Car wireless charging technology V2G, every car is a power bank - News

Earlier, Bloomberg New Energy Finance (BNEF) reported that it is expected that there will be 559 million electric vehicles in the world by 2040, which will have a significant impact on the power network on which the world depends. By 2050, global electricity demand is expected to increase by 57%, and the demand for electricity supply in Southeast Asian countries with large populations such as China and India is expected to double.

At CES (International Consumer Electronics Show), Honda showed the concept of electric vehicle wireless charging V2G (full name Vehicle-to-grid Vehicle-to-Grid), which can realize the wireless connection of electric vehicles and power network. V2G is also a two-way energy transmission system that can not only charge the vehicle, but also supply power to the home or power network. The purpose is to alleviate the surge in power demand and effectively handle this peak power demand pressure.

Vehicles with V2G technology can deliver power from the vehicle's battery to the power grid when the battery is fully charged but idle. This two-way power transfer technology charges the electric vehicle when the power generation is greater than the power consumption; when the power consumption is greater than the power consumption, the electric vehicle is discharged to the power grid, thereby helping to offset the gap between the power supply and demand, which is beneficial to the link Stability of electricity supply and demand.

Different from the traditional charging pile charging, the V2G system realizes non-contact charging and discharging through the charging board, which means that the vehicle equipped with the V2G system has the wireless charging function and will become the standard configuration. The vehicle is simply parked on the wireless charging floor, and it can be charged or discharged non-contact, without any bulky charging gun, which makes the charging experience more convenient.

Now, some car companies around the world have begun to experiment with V2G technology, including Nissan, Mitsubishi, PSA Group, etc. They all hope that in the future, the V2G system can become a common technology for global car manufacturers to integrate electric vehicles and power grids. Actively cooperate with the development of the future power system.
