Problems solved by technology
[0002] Since the electric energy used by the electric vehicle is the direct current energy of the battery pack, the on-board charger is usually used to charge the battery pack on the car. According to the prescribed AC charging mode, the mains electric energy on the AC charging equipment pile is converted into AC by the on-board charger. After DC, charge the battery pack again. How should the on-board charger be reliably connected to the mains on the AC charging equipment pile according to the relevant requirements? A variety of charging modes, charging mode 1 and other charging modes also have control differences, charging mode 1 connection mode B circuit is the national standard mode in the field of electric vehicle charging, but in the specific circuit connection relationship, each needs to pay creative work, and this is urgently needed Field technicians solve the above technical problems

The invention discloses an electric vehicle alternating-current charging mode-I control device and an electric vehicle alternating-current charging mode-I control method. Voltage acquisition signal input ends of a voltage acquisition module are connected with two ends of a power storage battery pack respectively. A signal output end of the voltage acquisition module is connected with a voltage acquisition module input end of a vehicle control device. The vehicle control device is connected with a vehicle-mounted charger. A cable wire current capacity identification end of the vehicle control device is connected with a charging confirmation detecting point. One end of a first relay coil is connected with a port of a charging signal output end of the vehicle control device, and the other end is grounded. One end of a contact of a first relay is connected with a positive electrode of a charging voltage output end of the vehicle-mounted charger, and the other end is connected with a positive electrode of a storage battery. One end of a third first relay coil is connected with an auxiliary power supply positive electrode end of the vehicle-mounted charger, and the other end is grounded. One end of a normally-open contact of a third relay is connected with a second storage battery, and the other end is connected with a power supply positive electrode input port of the vehicle control device.
Description
technical field [0001] The invention relates to the field of electronic circuits, in particular to an electric vehicle AC charging mode-control device and control method. Background technique [0002] Since the electric energy used by electric vehicles is the DC power of the battery pack, the on-board charger is usually used to charge the battery pack on the car. According to the specified AC charging mode, the mains power on the AC charging equipment pile is converted from AC to AC by the on-board charger. After direct current, the battery pack is charged again. How does the on-board charger reliably connect to the mains on the AC charging equipment pile according to relevant requirements? After the connection, how does the on-board charger identify the allowable current of the connecting cable? A variety of charging modes, charging mode 1 and other charging modes also have control differences, charging mode 1 connection mode B circuit is the national standard mode in the f...
