Vehicle bidirectional charging mode control system and method

Abstract

The invention discloses a vehicle bidirectional charging mode control system and method, belonging to the technical field of electrical systems. The invention receives the alternating current delivered by the charging pile through the bidirectional inverter controller, converts the alternating current into direct current, and transmits the direct current to the on-board battery pack, and the on-board battery pack charges according to the direct current, and switches the current working mode to the charging mode, When the inverter function of the target vehicle is turned on, the vehicle controller switches the current working mode of the on-board battery pack to discharge mode, so that the on-board battery pack transmits DC power to the bidirectional inverter controller, and the bidirectional inverter controller will receive The received DC power is converted into AC power, and the load equipment of the target vehicle is powered according to the AC power, realizing bidirectional charging of the battery and load equipment, and the dual-battery charging process is not affected by the power-on and power-off of the vehicle, making bidirectional charging more convenient. It is flexible and also improves the stability of bidirectional charging.

Description

technical field [0001] The invention relates to the technical field of electrical systems, in particular to a vehicle bidirectional charging mode control system and method. Background technique [0002] Pure electric vehicles are a new type of low-pollution travel mode, with unique advantages that other new energy vehicles do not have. Pure electric vehicles have a bidirectional inverter function and can be charged in both directions, that is, electric vehicles can receive alternating current to charge the vehicle, and also It can output alternating current to the load, but the existing two-way charging requires relatively harsh conditions. During the process, the pure electric vehicle cannot be powered on and off, and the two-way charging needs to add additional hardware circuits to realize it.
