Mode 1:
There is no control box on the EV chargers. When charging the car, it is directly plugged into the household AC socket through the cable of the EV chargers. It can not 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.
Mode 2:
The main charging mode of portable EV chargers on the market. The difference from Mode 1 is that a protection device, that is, an adapter, is added. At the same time, communication is established with the vehicle through the control wire, and charging parameters can be exchanged between the vehicle and the charger. This mode is generally used for portable EV chargers.
Mode 3:
The difference between Mode 3 and Mode 2 is that the charging connector is not connected to the household AC power grid, but to a dedicated AC power supply device- AC EV charger. At this time, the charging connector can be without an adapter because the AC EV charger itself plays a protective role. Mode 3 can not only ensure safety of charging, but also increase the charging speed. AC EV chargers are Mode 3.
Mode 4:
Mode 4 is a DC charging mode that charges electric vehicles in a short time. It has high-power and high-voltage working conditions, such as Tesla super charging stations, which are generally not for home use, but are specially set up at fast charging stations. The charging current of mode 4 is large, and the current is generally DC 80/125/200/250A or even higher, so the charging speed is naturally the fastest. However, DC charging has very high installation requirements and costs, and long-term DC charging will affect the life of the battery.
