A picture takes you to understand the 4 charging modes of EV chargers.


  1. Mode 1 (MODE1)

There is no control box on the charging gun. When the car is charging, it is directly plugged into the household AC socket through the cable of the charging gun. It cannot establish communication with the vehicle, and the maximum current intensity, voltage, temperature, etc. cannot be confirmed during charging. The charging method of Mode 1 has basically been eliminated due to poor safety.

  1. Mode 2 (MODE2)

At present, the main charging mode of portable chargers on the market. The difference from mode 1 is that a protection device is added, that is, an adapter. At the same time, communication with the vehicle is established through the control wire, and charging parameters can be exchanged between the vehicle and the charger. This mode is generally used for on-board chargers, and the charging current is small. , generally 8-16A.

  1. Mode 3 (MODE3)

The difference between mode 3 and mode 1 and mode 2 is that the charging gun is not connected to the household AC power grid, but is connected to a dedicated AC power supply device, that is, an AC charger. At this time, the charging plug can have no adapter, because the AC charger itself plays a protective role. Mode 3 can not only ensure the safety of charging, but also improve the charging speed to a certain extent (10/13/32/63A). Both the AC charger and the wall-mounted charging case are MODE 3.

  1. Mode 4 (MODE4)

Mode 4 is a DC charging mode, which charges electric vehicles in a short period of time. It has high-power and high-voltage working conditions, such as Tesla super charging stations, which are generally not for household use, but are specially set up in fast charging stations. The charging current of mode 4 is larger, and the current is generally DC 80/125/200/250A or even higher, so the natural charging speed is also the fastest. However, DC charging has very high installation requirements and costs, and long-term DC charging will affect the life of the battery.
