What is V2G charging technology?

According to authoritative statistics, by 2020, the number of pure electric vehicles in China has reached 4 million. With the rapid growth of the number of electric vehicles, it will have a certain impact on the power grid. The increase of power capacity demand will aggravate the peak valley difference of power consumption, which will have a great impact on the power grid and affect the normal life of residents. At this time, V2G charging technology can effectively alleviate this phenomenon, but do you know what V2G charging technology is? Today, Raines will take you to understand V2G charging technology.

V2G is actually the abbreviation of vehicle to grid, which means that the interaction between electric vehicles and power grid can be realized. Thus, when the load of electric vehicle is low, it can absorb electric energy, release electric energy when the load of power grid is high, and earn the difference income. If V2G is realized, everyone can regard each electric vehicle as a small charging treasure. When the load of the grid is low, the charging gun is mainly inserted, and the energy can be stored automatically. When the load of the power grid is high, the power battery energy can be released into the grid, so it can be effective? Relieve grid pressure.

For electric vehicle users, the vehicle can be charged at low price, and the energy stored in the vehicle can be sold to grid companies at high price, so as to obtain cash subsidies and reduce the use cost of electric vehicles.

For grid companies, not only can reduce the power pressure caused by the development of electric vehicles, but also use electric vehicles as energy storage devices to regulate load, improve the efficiency and reliability of power grid and reduce the investment in energy storage construction.

For automobile enterprises, V2G technology enables users to effectively reduce the cost of using electric vehicles. In case of natural disasters, V2G technology can also be used to use electric vehicles with power output function as emergency power supply, and the use of electric vehicles is added invisibly, thus promoting the production and sales of electric vehicles.

The ac/dc charge discharge integrated machine with V2G technology is the one with charge discharge. The charge discharge integrated machine is a high-end intelligent charging and discharging product launched for the new energy electric vehicle market. The product supports charging and off grid discharge. It is suitable for different charging environment, providing safe, reliable, stable and efficient charging service for electric vehicles.

The main functions of the system are: cutting peak and filling valley, regulating power grid; Low charge and high level, earn difference; Cycle charging and discharging, battery inspection; Regularly charge and discharge to protect the battery; Flexible charge discharge.

And with V2G technology, the used vehicle battery can be "turned into treasure". V2G technology can provide the possibility of recycling the used power battery group. Although the waste battery is not enough to support the daily vehicle demand, it can be used as the energy storage unit to supply the power grid in reverse during the peak value of power consumption, so as to realize "transforming waste into treasure".
