电动汽车充电电缆是如何工作的？
纵观汽车发展史，传统燃油汽车经历了社会和技术发展到电动汽车的普及，乘用车在减排和环保方面似乎有了新的思路，其中，主要有两个方向：起电和加氢。
有四种类型的电动汽车充电模式。其中，人们日常使用的模式是模式二和模式三组合式的家庭充电。如下
充电方式二：单头充电枪+电缆+控制箱+插头接单相市电组合
充电方式三：单头充电枪+电缆+控制箱+插头接单相市电组合
电动汽车主要由直流电机和电池组驱动，其他原理基本相同。此外，直流充电桩主要由模块、主控板、通讯板、人机界面、充电接头、计费系统、空气开关、防雷、放电电阻、绝缘检测等组成，适用于社会车辆和公共巴士；电动汽车的大概行驶距离为30-90KW/h，续航里程为200-500km；（公交车）承载60-240kw/h，续航里程当然是充电桩功率越大，充电速度越快。
如果您正在为您的商业楼宇、楼宇住宅安装电动汽车充电设备，这里可以为您提供更多充电解决方案，解决电动汽车充电问题。在使用不同尺寸的电缆和连接器连接直流或交流充电桩设备时，更好地为电动汽车充电并提供更好的续航里程。
Mode 1:
Mode 1 (Schuko mode) refers to a household socket that uses a simple extension cord for charging without any safety device. This model is very unpopular. Volkswagen manufacturers no longer use it because leaders are always alive. Mode 1 is dangerous, and the battery charging speed is slow (from 0 to 100%, nearly 40-60 hours).
Mode 2:
Mode 2 is also called portable electric vehicle charger. This mode supports charging from Schuko and CEE sockets. The built-in charger in the vehicle converts AC * to DC * * and controls battery charging. In addition, we can plug this electric vehicle charging mode lead into a standard socket (usually 15A-16A), which takes 14-16 hours to fully charge the battery. It depends on the size of the battery.
Mode 3
It is a fixed point AC charger for residential or light commercial use. This mode 3 can be used in two ways. For example, the charging cable can be directly connected to the charging unit or it can be a detachable cable that you can carry in the vehicle and then insert into the charging unit. With Mode 3, the battery will charge in 4-9 hours.
Mode 4
Equipment using DC charging cables and connectors. In other words, "fast charger" mode 4 is the fastest way to charge the electric vehicle. Fast charging stations are very expensive, which is why they are often public. It is not approved by all electric vehicles. This mode can charge the car to 80% within 1 hour.
Electric bus charging infrastructure design
A major part of preparing for the electric bus ecosystem is building an adequate and efficient bus charging infrastructure.
The dynamics of EV charging infrastructure are different from other automotive segments such as electric 2W, 3W and automotive. Charging infrastructure has two main parts: charging solutions and power infrastructure.
Among them, the distinction between electric bus charging solutions:
Fully reliant on commercial charging; unlike other automotive sectors,
1. Electric buses do not have the specifications and models of household charging pile cables;
2. Compared with other vehicles, the battery capacity is 100kWh~200kWh, etc.;
3. The output efficiency value of the charging connector is different from the charging connector selected by other vehicles, generally 80~120kW, etc.; 4. Electric buses are used in public transportation, transportation industries, etc., and the charging equipment used for vehicles is compared with other electric vehicles. The automotive sector needs to pay higher capital;
Of course, while electric buses (passengers) provide guarantees for electricity, the power infrastructure needs to be coordinated through various sites and planning to achieve optimized charging facilities, provide additional safety measures, control systems and auxiliary infrastructure.
Under the current market operation, electric buses develop various operations through different business models. Among them, the operating cost model is one of the modes of establishing and operating the vehicle charging infrastructure. Under the charging infrastructure layout, the manufacturers of charging equipment and charging cables operate through the construction of the entire charging network to jointly maintain the vehicle charging infrastructure.

Consumer demand for electric vehicle charging cables
With the development of technology in the automotive era, electric vehicles have gradually become one of the mainstream vehicles on the road. Of course, the electric vehicle charging cable is important as a connecting device in the charging field.
With the general increase in electric vehicle charging areas, some of which are charged through lamp posts, charging piles, etc., and other innovations, it is necessary to ensure that the cable provided by the electric vehicle can fully utilize every kilowatt, so that the owner can reduce the time waiting for the car to charge, Increase effective efficiency in charging electric vehicles.
as standard for charging cables. Not long ago, there were no clear standards for the charging equipment that every new car was equipped with. Automakers take note. This comes after detailed R&D and production of various power cords supplied by car manufacturers. Electric vehicle charging cables are now required to be implemented across the entire range of standards to make owning an electric vehicle simpler and more practical. Among them, the market currently has European standards, international standards and American standards to standardize charging cables.
When the situation is clear and clear, the requirements for charging cables required by users and consumers are fully reflected, and there are goals for charging cables; as an auto parts manufacturer, there are plans to sell electric vehicle charging cable products, providing more electric vehicle users. Consumers offer more practical and convenient cables for charging.
EV mode 3 charging cable
With the popularity of electric vehicles, passenger vehicles seem to have the best way to reduce emissions, which are mainly divided into two directions: electrification and hydrogen energy. For the comprehensive development of electric vehicles in the future, there are still many deficiencies. In any aspect, the transmission speed is expected by the masses. For example, the rapid operation of logistics and the rapid charging of charging piles are still what our people expect
As one of the important transmission channels and tools for vehicles to connect the charging pile equipment, the charging cable of the charging pile has four kinds of classified charging modes. For example, charging mode 3: the combination mode of single head charging gun + Cable + control box + plug connected to single-phase mains
The difference between charging mode 2 and charging mode 1 is that the controller is increased. Charging mode 2 has complete protection measures compared with charging mode 1, including over-voltage, under voltage, over-current, over-temperature and leakage power-off protection. Charging mode 1 has no protection measures. Charging mode three-phase for the first two modes, mode three increases the charging current to improve the charging speed, and the demand for charging safety will be higher. The charging mode 4 is a DC charging gun.
There are three connection methods:
The charging cable is connected with the electric vehicle end and pluggable with the power grid connection end;
The charging cable is connected with the power grid connection end and can be unplugged with the electric vehicle end;
The charging cable can be pluggable with the electric vehicle end and the power grid connection end.
The application can be used as a charging infrastructure for electric buses, electric trucks / trucks and other vehicles. Of course, for more information about the specifications of charging cables, or visit EV charging cable manufacturers, please visit or search: Https://www.omgevcable.com
How long does it take to charge an electric car at a charging station?
From the understanding, electric vehicles can be charged at home or at any public charging station. It only takes 30 minutes to fully charge the car, or it can take up to half a day.
However, as we move towards a new world of electric vehicles, onboard cables should be able to take advantage of faster charging speeds that will soon become more widespread at roadside charging facilities or charging stations.
Limiting the amount of time electric vehicles need to be charged before they get back on the road is an important factor driving their adoption, and many studies have focused on reducing these charging times. A new advancement utilizes alternative cooling technology to remove heat from the charging cable, allowing it to handle the type of current required to charge an electric vehicle within five minutes.
What size charging cable is used for electric buses
With the development of new technologies for electric vehicles, they can be charged at ultra-fast charging speeds such as 100-150kW, which are for users to see in auto parts advertisements. However, this requires finding the right charging cable and connector to provide the achievable power, which can only be found in custom charging cables.
Among them, the charging interface of an electric bus, as a hybrid passenger car, generally has an AC charging port, and a pure electric passenger car has two charging ports, one is an AC interface (connected to an AC power pile), and the other is a DC interface (connected to a DC power pile). . However, the bus only has a DC port. Because the single gun of the DC charging gun is the largest, the charging speed is the fastest. This is a good performance for the fast operation of public transport.
Electric buses, also known as electric medium-sized buses, are powered by on-board power supplies. It includes battery electric vehicles (Bev), hybrid electric vehicles (HEV) and fuel cell electric vehicles (FCEV). Three core components: battery, motor and electronic control. It is the same as the charging principle of other electric vehicles. It uses the charging cable of the specification through the charging station and the connector to transfer the power to achieve a fully charged condition of the whole vehicle.
Of course, with a good connector and a high-quality charging cable, the transmission will be more effective during the charging process. OMG is committed to becoming a world-class provider of new energy vehicle cable solutions.

What are the #high-voltage harnesses of automobiles
In new energy vehicles (pure electric as an example), the high-voltage harness can be divided into five parts
(1) Power battery high voltage cable: that is, the harness connecting the power battery to the high voltage box
(2) Motor controller cable: that is, the harness connecting the high-voltage box to the motor controller
(3) Fast charging harness: that is, the harness connecting the fast charging port to the high-voltage box
(4) Slow charging harness: that is, the harness connecting the slow charging port to the on-board charger
(5) High voltage accessory harness (high voltage harness assembly): that is, the harness connecting the high voltage box to DC / DC, on-board charger, air conditioner compressor and air conditioner PTC.
Shielding material of high voltage harness
In order to ensure the safety of high-voltage and high-current wire harness, it is very important to select the insulation materials used for
vehicle cables. The shielding materials of high-voltage harness are as follows:
(1) LSZH: LSZH can be divided into po (polyolefin) and EPR (ethylene propylene rubber), of which Po cable materials are the mainstream. There are a lot of AI (OH) 3 and Mg (OH) 2 inorganic flame retardants in the formula of Po type LSZH flame retardant cable material, which makes the cable material have better flame retardant, low smoke, halogen-free, low toxicity and other characteristics, but also makes it different from other non flame retardant materials and halogen-containing flame retardant materials in physical and mechanical properties, electrical properties and extrusion process properties.
(2) TPE: TPE is a polymer material with both rubber and thermoplastic characteristics. It shows high elasticity of rubber at normal temperature and can be plasticized at high temperature. However, this material is not wear-resistant and cannot meet the requirements of high-voltage wire harness for electric passenger vehicles.
(3) XLPE: XLPE is made of ordinary PE (polyethylene) material with temperature resistance grade of 75 ℃ after radiation crosslinking. Its temperature resistance grade can reach 150 ℃, and it has excellent physical and mechanical properties, overload resistance and long life, but it is not flame retardant.
(4) Silicone rubber: silicone rubber has high breakdown voltage, so it has arc resistance, leakage trace resistance and ozone resistance. It also has good high and low temperature resistance, high temperature resistance up to 200 ℃, good insulation performance, stable performance and flame resistance under high temperature and high humidity conditions. After comparing the properties of the above materials, silicone rubber has become the first choice of high-voltage cable insulation materials for electric passenger vehicles because of its good physical and mechanical properties, long service life and low price.
performance requirements for automobile high voltage harness
(1) Electrical performance: in terms of electric passenger vehicles, high-voltage cables mainly play the role of transmitting energy, which needs to transmit the energy of the battery to each subsystem. Therefore, the high-voltage harness of electric passenger vehicles designed must meet the high-voltage and large current transmission.
(2) Shielding: during the operation of electric vehicles, the repeated changes of electrical loads and the frequency conversion technology widely used in the system cause sharp fluctuations in harness voltage, current and frequency, resulting in large electromagnetic interference. Generally, high-voltage connectors are 360 ° shielded, and high-voltage cables are shielded cables.
(3) Mechanical performance: due to the large diameter of the high-voltage cable of the electric passenger vehicle, special routing is required, that is, the high-voltage harness of the electric passenger vehicle is arranged outside the vehicle. Therefore, the high-voltage harness of the electric passenger vehicle must be designed for mechanical protection, dust prevention and waterproof
(4) Durability: the high-voltage harness shall have the properties of temperature resistance, weather resistance, corrosion resistance, vibration resistance, cable abrasion resistance, etc., and shall have large safety margin and connection life to ensure long-term reliable operation of the vehicle. In order to improve the service life and quality of the high-voltage harness, the connection between the high-voltage cable and the high-voltage connector should be reinforced, the connection between the high-voltage connectors should be locked, and the wiring scheme should be optimized. The high-voltage harness material should be wear-resistant
High-voltage cabke,unshielded cable

What is the composition of automobile high-voltage cables
As an automotive interior device to operate effectively, automotive high-voltage cables play an important role in it. The technology of key components such as batteries, motors, and electronic controls is inseparable from high-voltage wiring harnesses.
The appearance of high-voltage cable sheath is generally cross-linked polyethylene insulation, XLPE, PVC, etc., but the structure of high-voltage cable is composed of core, inner insulation layer, semiconductor layer, steel armor, filler, outer insulation layer, etc.; conductor is copper or plated Tin copper, but in conventional cables, copper is mostly used as the conductor. Cables with different uses use different materials, but the cores are copper or aluminum. The specific use of copper, aluminum or tinned copper is related to the price of the market materials and can only be used in special cables.
However, how many layers of high-voltage cables do they play?
The high-voltage electricity is sealed to three layers, the innermost layer of the first layer is an insulating layer, and the next layer is a conductive layer, among which there are shielded or unshielded cables. The shielded cable has an improved electric field. As a measure of distribution, a conductor wrapped with a conductor outside the conductor is called a shielded wire. The conductor wrapped with a conductor outside the conductor is called a shielded wire, and the wrapped conductor is called a shielding layer, which is generally a braided copper mesh or copper moor (aluminum). Of course, the inside of the cable is a conductor, which conducts electricity as a whole product. The overall cable forms an insulating layer that truly protects the entire cable, and is generally divided into three layers for the correct function without damaging the cable.
Problems and solutions encountered in the charging of new energy vehicles
The main problems faced by new energy vehicle charging include: long charging time, insufficient charging facilities, opaque charging fees, and inconsistent charging methods.
To address these issues, the following solutions can be taken:
1. Long charging time: New charging technologies can be researched to improve charging speed, such as fast charging technology, wireless charging technology, etc.
2. Insufficient charging facilities: Government agencies and units can increase investment in the construction of charging facilities and encourage enterprises to increase their efforts in the construction of charging facilities, such as building charging stations and setting up charging stations in public places.
3. Untransparent charging fees: Reasonable charging standards can be established and supervision strengthened to prevent the occurrence of arbitrary charging.
4. Inconsistent charging methods: It is possible to strengthen the formulation of charging standards, establish a unified charging interface and mode, and facilitate users to charge in different places.
In summary, strengthening guidance on the construction of charging stations, encouraging enterprises to invest in the construction of charging facilities, improving charging standards and regulatory mechanisms can effectively solve the problems faced by new energy vehicle charging.

What is "smart" charging for electric vehicles
Smart charging refers to a charging system that provides a shared data connection between the electric vehicle, the charging station and the user. Smart charging allows monitoring, managing and limiting energy consumption, thus optimizing energy consumption in terms of cost and usability.
According to news reports, the benefits of smart charging are so prevalent that a revision by a professional body has resulted in smart chargers only being eligible for it. Along with user benefits such as reduced operating costs, scheduled off-peak rate usage and avoidance of annoying trips through load management, smart charging is now most often installed.
However, while smart charging offers inherent benefits, it does pose installation problems for electricians.
While some chargers have adopted Wi-Fi connectivity to establish data connections, many charger manufacturers have identified Wi-Fi-related issues (such as range and signal loss due to construction) and have chosen to use "hardwired" data connections to improve reliability and user experience.
This means that electricians typically need to install two cables: one for power and one for data. This, of course, results in more work, longer installation times, more inventory, and often having to route both cables through difficult routes into the building.
In this area of charging cables, more cable manufacturers' R&D teams are identifying problems so that electric vehicle charging cables can be better improved and give users an enhanced experience.

Explanation and Application of Bidirectional Charging of Electric Vehicles
With the constant changes in international fuel prices, changes in the electric vehicle market industry continue to occur, especially as a charging cable for vehicles and charging piles, which may be a trend in the future. However, in response to global performers, a new innovative opportunity and business model has emerged: two-way charging.
Bidirectional charging is an emerging technology that enables a growing number of electric vehicles to not only store energy for driving, but also power buildings and the wider grid. Keep refrigerators, lights, and the Internet running in homes and other buildings during an emergency, eliminating or reducing the impact of most power outages. Bidirectional charging also has the potential to make the entire grid greener and more efficient, with increased and better use of wind and solar energy.
In simple terms, bidirectional charging is when your car battery can receive energy from the grid and share the electricity it produces. However, there will be two main categories of distinction.
1: Vehicle-to-Grid (V2G): Energy is output from the EV charger to support the grid.
2: Car to Home (v2h): Energy is used to power a home or business.
The inevitable question, then, how does this work for charging my electric car?
When you charge an electric car, the alternating current (AC) it receives from the grid needs to be converted to direct current (DC) in order for it to power the car battery in the correct form. Of course, this can be done via a converter in the vehicle or an external charger.

How to solve the problem of charging time of freight forwarders
So far, electric trucks have either been used for long distances, or additional charging stations have been set up. However, the tight schedule in the shipment does not actually allow any additional docking points to charge the battery. Therefore, the promotion of new technologies in the field of charging technology is crucial to make alternative drives attractive to logistics companies.
The development of innovative charging system not only ensures the local zero emission transportation of goods. Trucks can be used as energy storage for renewable energy sources (such as wind turbines) when stationary. These plants can generate energy even if the demand is low. Therefore, using trucks with large battery capacity for intermediate storage and subsequent power transmission can not only store energy, but also promote the stability of the power grid by buffering the peak demand. The problem of charging time can be solved, which can improve the transportation cost and reduce the electrification of commercial vehicles used by the transportation department to optimize the grid connection.

Browse the website of electric vehicle home charging cable
Electric cars are becoming more and more popular every day. By the end of July, nearly 130000 new electric vehicles had been sold this year, an increase of 50% over the first seven months of last year.
But the reality is still that if you can charge it at home instead of relying on the public charging network, then electric vehicles are a more viable option. Electricity is much cheaper. You can charge your car when you sleep, instead of waiting for it to charge when you go out.
Of course, this also applies to plug-in hybrid vehicles, because their smaller batteries are more likely to need to be recharged every day if you want to get the most from them.
If you charge at home, you really need a wall box instead of relying on the standard three pin plug and socket. Although you can charge the car in this way, if your home wiring does not meet the requirements, it will be slower and more dangerous. Wall boxes are almost a must-have.
Inevitably, even in the relatively early days of the current EV revolution, many suppliers have provided home charging solutions, and it may be a task to try to determine which one is most suitable for you.
For most families, a 7kW wall box is enough, because this is all the power that your home power device may be able to provide. If you are lucky enough to have a three-phase power supply, you may get a 22kW wall box, which can charge your car faster.
Here, auto experts focus on some of the best websites to provide advice and equipment for drivers who want to charge at home. For simplicity, we list them in alphabetical order, as well as one we avoid.

Details of standard requirements for insulation materials of new energy cables
With the rapid development of the new energy industry, new energy cables, as key components of power transmission, have increasingly stringent standard requirements for insulation materials. The following is a detailed analysis of the standard requirements for insulation materials of new energy cables:
1. Physical performance requirements
The physical properties of insulation materials of new energy cables must comply with national standards, mainly including:
Tensile strength: ensure that the cable is not easy to break when stretched by external force, and ensure the stability and safety of the cable.
Elongation at break: reflects the elongation ability of the material before breaking, and is an important indicator for evaluating the flexibility of the material.
Hardness: Appropriate hardness can not only ensure the insulation performance of the cable, but also avoid excessive wear during installation and use.
2. Electrical performance requirements
Electrical performance is the core requirement of insulation materials of new energy cables, mainly including:
Dielectric strength: indicates the ability of the material to withstand the action of the electric field without being broken down, and is a key indicator for evaluating the insulation performance of the cable.
Volume resistivity: reflects the difficulty of charge transfer inside the material. High volume resistivity means that the material has good insulation performance.
Dielectric loss: Under the action of the electric field, part of the electrical energy in the insulating material will be converted into heat or other forms of energy and lost. The smaller the dielectric loss, the higher the transmission efficiency of the cable.
In summary, the standard requirements for new energy cable insulation materials cover physical properties, electrical properties, heat resistance, environmental aging resistance and other aspects to ensure that the cable can maintain stable insulation performance and good operating conditions in various application scenarios.
Introduction to charging pile of DC charging device
DC charging pile refers to the pile that uses DC charging mode to charge the traction battery assembly of electric vehicles. The DC charging mode is to directly charge the traction battery assembly with the controllable DC power output from the charging pile.
