This charging standards are primarily used in the United States and Canada. AC max voltage is 240V AC, with a max current of 80A. For DC charging, max voltage is 1000V DC, max current 500A DC.

CHAdeMO（Charge de Move）from Japan, designed to provide high-power quick charging services for electric vehicles. This standard was initially developed by a consortium of companies, including Japan Electric Vehicle Club, Tokyo Electric Power Company, and Nissan Motor Co., and has gained widespread international recognition.

New energy vehicles typically feature an electric drive system consisting of a battery pack, an electric motor, and a controller. The battery pack converts chemical energy into electrical energy, the electric motor converts electrical energy into mechanical energy, and the controller manages the output of electrical energy and controls the operation of the electric motor.

two important metrics that impact vehicle charging: charging power and charging time.

New Energy Vehicles (NEVs) refer to vehicles that utilize new energy technologies and use non-traditional fuels or energy sources as their power source, characterized by zero or low emissions and being energy-efficient and environmentally friendly. Based on the primary power source and driving method, NEVs can be categorized into the following main types:
