The difference between charging pile dual guns charging at the same time and taking turns charging

2020-09-08
The difference between charging piles with dual guns at the same time and alternate charging depends on the manufacturer's power distribution strategy. If the charging piles are equally distributed, then the charging piles with dual guns are charged at the same power. If it is intelligently distributed according to the battery SOC state, then The charging power of the dual guns of the charging pile is also different at the same time. Some charging tips can only be charged individually, but the power can reach the maximum power of the charging pile.

1. When the charging pile is in the dual-gun charging state, the A charging gun and the B charging gun are plugged into the charging sockets of the electric vehicle and connected to the A charging interface and the B charging interface of the electric vehicle respectively. The a charging interface and the b charging interface communicate through the BMS Line connection; A charging gun communicates with B charging gun to detect whether the two parties can find the other party. If there is no response, it is considered that the BMS communication line of the electric vehicle is not connected.

2. The charging gun A and the charging gun B communicate with the electric vehicle respectively. The one that responds to the communication serves as the master gun, and the one that does not respond serves as the slave gun.

3. Both the A charging gun control unit and the B charging gun control unit are connected to the charging control unit through the CAN bus, and the A charging gun control unit and the B charging gun control unit communicate with each other.

4. The main gun control unit communicates with the electric vehicle to obtain charging demand information.

5. The master gun control unit separately informs the power distribution unit of the master gun control unit and the power distribution unit of the slave gun control unit according to the received charging demand information.

6. The power distribution unit of the master gun control unit and the power distribution unit of the slave gun control unit respectively send corresponding current and voltage signals to the corresponding charging guns.

7. A charging gun and B charging gun simultaneously charge the electric vehicle. Among them, one of the charging guns is set to 0 guns, and the other is set to 1 gun. When the two guns can communicate with each other, the gun with the smallest address is 0 gun as the master gun, and 1 gun is the slave gun.
