ev charging connectors
The EV charging connector is an important device for charging new energy vehicles. It can transmit electricity from the charging pile or household socket to the battery pack of the car. According to different regions and standards, there are many types of EV charging connectors, mainly divided into DC EV charging connectors and AC EV charging connectors.
The DC EV charging connector is a high-current, high-power EV charging connector, which is generally equipped in the fast charging station of new energy vehicles. The DC EV charging connector can directly input DC power into the battery pack of the car without the need for conversion by the inverter inside the car, so it can improve the charging efficiency and speed. There are generally four standards for DC EV charging connectors: Japanese standard (CHAdeMO), American standard (CCS1), European standard (CCS2), and Chinese standard (GB/T). These four standards differ in interface shape and parameters, so DC EV charging connectors of different standards cannot be used interchangeably.
The AC EV charging connector is a low-current, low-power EV charging connector, which is generally used at home or carried in the car. The AC EV charging connector needs to convert AC power into DC power through the inverter inside the car, and then input it into the battery pack of the car, so the charging efficiency and speed are relatively low. There are also three standards for AC EV charging connectors: American standard (Type 1), European standard (Type 2), and Chinese standard (GB/T). These three standards also differ in interface shape, but are relatively close in parameters, so they can be converted through an adapter.
Let's learn more about the AC gun. Taking the European standard EV charging connector under the name of AUPINS as an example, the IEC EV charging connector follows the European standard (Type 2) and obtains CE certification. In terms of the product concept, the IEC EV charging connector starts from the design aspect and launches two types of double gun heads and single gun heads. The difference between the two is mainly reflected in the compatibility of use. The double gun head belongs to the "independent finished product". It does not need to be docked (installed) to the charging pile by itself during use. It is plug-and-play.
In life, we can choose the right EV charging connector according to different occasions and needs. Generally speaking, if we want to quickly replenish the car with enough mileage, we can choose to use the DC EV charging connector of the fast charging station, but we must pay attention to choosing the standard that matches the car. If we want to slowly charge the car at home or in a public parking lot, we can choose to use the AC EV charging connector of the household socket or AC charging pile, but we must pay attention to safety and regulations.
