![]() The capacity limitation of the DC/AC pile: currently for electric vehicles, generally low power It is AC AC pile (20kW, for example, CHAdeMO is 50kW, Tesla's super charge is 120kW). ![]() The main influencing factors of the charging pile are the capacity limitation of the DC/AC pile, the interaction between the charging pile and the battery pack, and the 400V/800V technical route. ![]() This power has a small impact on the large power grid. And if it is only for the fast charging of small batteries such as mobile phones, the impact on the power grid is basically zero for electric bicycles, it is mainly some adjustments in the safety of transmission and distribution. Generally speaking, it is: to improve the instantaneous energy supply capacity, and prepare the transmission capacity (wires) required for power transmission and distribution. Or a local photovoltaic power plant/distributed fuel cell power plant is working. It will not have a relatively large impact on the overall operation of the power grid. For example, if you put a battery pack to make a large power bank, you can carry out the battery (power bank) -> energy transmission in the car battery. Transmission and distribution side: mainly increase power supply capacity and allow transmission power to go online (Simply put, use a thicker wire that can send more current.)Įlectricity side: In fact, a simple solution is to increase resources in the fast charging station. Power generation side: add flexible units (flexible transformation of coal power to improve climbing ability, and introduce more flexible but high-cost gas turbine units) to improve the ability to respond to power changes. For fast charging, this means that we can do work in the following aspects: Therefore, power generation/power consumption should be matched at all times as much as possible, and rapid changes in power consumption in a short period of time will bring challenges to the transmission and distribution links. If you have some basic understanding of the power grid, everyone will know that the power grid actually needs to generate and use electricity immediately, and balance the power all the time.
