The difference between charging at the same time with two guns of the charging pile and charging in turn depends on the power distribution strategy of the manufacturer. If the power of the charging pile is evenly distributed, then the simultaneous charging of the two guns at the charging pile will have the same power. If it is intelligently distributed according to the state of the battery SOC, then The charging power of the two guns of the charging pile at the same time is also different. There are also charging gun heads that can only be charged individually in turn, but the power can reach the maximum power of the charging pile. 1. When the charging pile is in the charging state of two guns, the A charging gun and the B charging gun are inserted into the charging socket of the electric vehicle and connected to the A charging interface and the B charging interface of the electric vehicle respectively, and the a charging interface and the b charging interface communicate through the BMS The A charging gun communicates with the B charging gun to check whether the two parties can find each other. If there is no response, it is considered that the BMS communication line of the electric vehicle is not connected. 2. Charging gun A and charging gun B communicate with the electric vehicle respectively. The one that responds to the communication acts as the main gun, and the one that does not respond acts as the slave gun. 3. Both the A charging gun control unit and the B charging gun control unit are connected to the billing 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 main gun control unit notifies the power distribution unit of the main gun control unit and the power distribution unit of the slave gun control unit respectively according to the received charging demand information. 6. The power distribution unit of the main gun control unit and the power distribution unit of the slave gun control unit send corresponding current and voltage signals to the corresponding charging guns respectively. 7. A charging gun and B charging gun charge the electric vehicle at the same time. Among them, one of the charging guns is set as gun 0, and the other charging gun is set as gun 1. When the two guns can communicate with each other and can find each other, the gun with the smallest address, that is, gun 0, is the master gun, and gun 1 is the slave gun.
