GB/T 20234.1-2015 stipulates the definition, requirements, test methods and inspection rules of the connecting device for conductive charging of electric vehicles. This standard applies to charging connection devices for conductive charging of electric vehicles, which:
① AC rated voltage not exceeding 690V, frequency 50Hz, rated current not exceeding 250A;
② DC rated voltage not exceeding 1000V, rated current not exceeding 400A. If the power supply interface of the charging connection device uses standardized plugs and sockets in accordance with GB2099.1 and GB1002, this standard does not apply to these plugs and sockets.
The GB/T Charger is renowned for its exceptional compatibility. Adhering to the GB/T charging standard, it is designed to accommodate a wide array of electric vehicles (EVs) that support this protocol. As a professional ev car charger supplier, our GBT charging piles are suitable for all electric vehicles on the Chinese market. If it is an imported model, a GBT adapter may be required. As long as it complies with the GB/T standard, our charger can deliver efficient and dependable charging. This broad compatibility makes the GB/T Charger a versatile choice for individual EV owners and commercial entities serving a variety of EV models.

As the electric system of an EV is a DC system, the AC power is not able to charge the power battery directly during AC charging, it needs to pass through a component called On-board Charger (OBC), which performs AC to DC conversion and is then supplied to the power battery after the voltage is transformed according to the command of the BMS.
In the case of DC charging, the DC pile itself is an AC/DC rectifier and DC/DC transformer, which can be converted from AC to DC directly outside the vehicle according to the needs of the BMS, replacing the role of the on-board charger, hence the ev chargers dc pile is also known as a non-on-board charger.
Charging interface is a "nine-hole" design, the picture shows the GB/T DC chargering gun head. The top middle CC1 and CC2 are used for electrical connection confirmation, while S+ and S- are the communication lines between the off-board charger and the electric vehicle. The two largest holes, DC+ and DC-, are used for charging the battery pack and are high current lines; A+ and A- are connected to the off-board charger and provide low voltage auxiliary power for the electric vehicle, with earth at the very center.
