Electric vehicle on-board charging solution

An electric vehicle (BEV) is a vehicle that is driven by a vehicle power source and drives a wheel with a motor. As the impact on the environment is smaller than that of traditional cars, its prospects are widely optimistic. At present, the biggest shortcoming in the development of electric vehicles is the construction of charging piles. How to deal with various environments and solve the problem of vehicle charging is the current priority. On the basis of predecessors, this paper summarizes the bus charging scheme, taxi charging scheme, micro-bus charging scheme, community vehicle charging scheme, enterprise vehicle charging scheme, urban micro-living charging scheme, stereo garage charging scheme, urban comprehensive charging station. .
