type1 type2 GB/T EV charging plugs difference

EV Charging plug interface standards are roughly divided into 3 categories: one is the American standard, the other is the European standard and GB/T . According to the charging technology, they are divided into direct current charging (DC) standard and alternating current charging (AC) standard. DC plugs are high-current, high-power charging EV connectors . They are generally equipped in fast-charging stations for new energy vehicles. They have high voltage and fast charging speed. AC charging plugs are used for home or portable charging ,which charging speed is relatively slow. 1. AC charger There are three main types, type1, type2 and GB/T, which can also be called American standard, European standard and China national standard. Of course, Tesla has its own standard charging connectors , but due to pressure, Tesla also began to change its standards according to market conditions to make its cars more suitable for the market. ①Type1:SAE J1772 Basically, the United State

The composition of EV charging plug

The composition of EV charging plug The EV charging plug is a device that connects the power supply to the battery when charging an electric vehicle. Its main components include: 1. Plug: used to connect input and output cables, responsible for transmitting electrical energy. There are terminals in the plug. 2. Insulated handle: used to hold the handle of the charging gun to protect fingers from the risk of electric shock. 3. Locking mechanism: Fix the charging gun on the electric vehicle battery charging interface. 4. Cable: A wire used to transmit electrical energy and a sheath to protect the wire. 5. Safety device: prevent overload and short circuit to ensure safety. 8. Control circuit: Processes the power input, output and electric vehicle battery signals, and controls the charging process. 9. Shell: Protects the internal components of the charging gun from being exposed to the external environment.

How does the AC EV chargers work?

How does the AC EV chargers work? AC charging means that on-board charger(OBC) converts the alternating current into direct current to charge the power battery to complete basic AC charging. The components of AC charging mainly include power supply equipment, such as Portable EV charger or AC charging station, OBC, slow charging EV connetors, high-voltage control box, power battery, VCU, BMS, high-voltage wires, low-voltage wires, etc. 1. On-board charger: converts alternating current into direct current according to control instructions to charge the battery. 2.AC charging connectors: divided into type1, type2, GBT EV connectors 3.VCU: Monitors the status of the vehicle and issues control instructions to the on-board charger to make it work or stop working, control its operating current and voltage, etc. It is the control brain of vehicle charging. Mode 2 charging : It is a charging cable with control box that connects the external power grid and the vehicle, and directly provides AC
