There are four main pain points: A. Battery standardization is too difficult. The separation of vehicle and electricity first requires the standardization of power batteries, BMS standardization, interface standardization, and software management standardization. Any vehicle upgrade must be compatible with the previous generation of products. Battery standardization is too difficult. Every car company wants to make its own electricity exchange standard. It is unrealistic for so many car companies to unify. B. The investment is large and the cost is high. The replacement of power needs to lay a large network, and the investment scale is far greater than charging. Build a power exchange network for a city to provide special tram exchange services. The cost can be recovered only after at least 6-8 years or even more. C. The deflagration hazard of the power plant is large, and the safety hazard is huge. D. It is difficult to improve the customer experience.

When the charging post is built, it should be used and managed well. The implementation of management responsibility and clear operation mode can make the charging pile safe and reliable. At present, the charging pile is faced with the problem of unclear management responsibility and unclear operation mode. There are some problems such as the aging of distribution facilities in the community, who will pay for the reconstruction, the quality of piles is mixed, and who will solve the hidden fire hazards. The same is true of public charging posts. There are not many DC fast charging piles with high investment standards and high power, but "problem piles" and "zombie piles" are common. In recent years, the number of charging pile construction and operators in China has grown rapidly, but the level of enterprises is uneven.

On board charging device refers to the device installed on the electric vehicle that uses the ground AC power grid and the on-board power supply to charge the battery pack, including the on-board charger (Figure 1-13), the on-board charging generator set and the operating energy recovery charging device. A AC power cable with a plug is directly inserted into the charging socket of the electric vehicle to charge the battery. On board charging devices usually use contact chargers with simple structure and convenient control, or inductive chargers. It is designed completely according to the type of on-board battery, with strong pertinence. Off board charging device, i.e. ground charging device, mainly includes special charger, special charging station, general charger, charging station for public places (Figure 1-14), etc. It can meet various charging modes of various batteries. Generally, the off board charger has large power, volume and weight to adapt to various charging modes.
