There are different classifications for electric vehicle charging equipment in the United States/Europe. The United States generally uses Level 1/2/3 to classify; while outside the United States (Europe) generally uses Mode 1/2/3/4 to distinguish.

Level 1/2/3 is mainly to distinguish the voltage of the input terminal of the charging pile. Level 1 refers to the charging pile directly powered by the American household plug (single-phase) 120V, and the power is generally 1.4kW to 1.9kW; Level 2 refers to the charging pile powered by the American household plug High-voltage 208/230V (Europe)/240V AC charging piles have relatively high power, 3kW-19.2kW; Level 3 refers to DC charging piles.

The classification of Mode 1/2/3/4 mainly depends on whether there is communication between the charging pile and the electric vehicle.

Mode 1 means that the wires are used to charge the car. One end is a common plug connected to the wall socket, and the other end is the charging plug on the car. There is no communication between the car and the charging device (there is no device in fact, only the charging cable and plug). Now many countries Charging of electric vehicles in Mode 1 mode is prohibited.

Mode 2 refers to a portable AC charging pile with non-fixed installation and vehicle-to-pile communication, and the charging process of the vehicle pile has communication;

Mode 3 refers to other AC charging piles that are fixedly installed (wall-mounted or upright) with vehicle-to-pile communication;

Mode 4 refers specifically to fixed-installed DC piles, and there must be vehicle-to-pile communication.
