Embodiment Construction

[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] refer to figure 1 , figure 1 It is a structural block diagram of the first embodiment of the vehicle bidirectional charging mode control system of the present invention.

[0050] The vehicle bidirectional charging mode control system includes: a bidirectional inverter controller 10, an on-board battery pack 20, and a vehicle controller 30;

[0051] In this embodiment, the function of the bidirectional inverter controller 10 includes converting the received AC power into DC power and converting the received DC power into AC power. In this embodiment, the bidirectional inverter controller 10 receives the AC power delivered by the charging pile, and converts The received AC power is converted into DC power, and the DC power is sent to the vehicle battery pack 20 .

[0052]It should be noted that the bidirection...

Abstract

The invention discloses a vehicle two-way charging mode control system and method, and belongs to the technical field of electrical systems. Alternating current transmitted by a charging pile is received through a two-way inversion controller and converted into direct current, and the direct current is transmitted to a vehicle-mounted battery pack; the vehicle-mounted battery pack conducts charging according to the direct current and switches the current work mode into the charging mode; when the inversion function of a target vehicle is started, a whole vehicle controller switches the currentwork mode of the vehicle-mounted battery pack into the discharging mode so that the vehicle-mounted battery pack can transmit the direct current to the two-way inversion controller; and the two-way inversion controller converts the received direct current into alternating current, and power supply is conducted for loading equipment of the target vehicle according to the alternating current. Two-way charging is achieved for a battery and the loading equipment, and meanwhile the two-way charging process is not influenced by power-on or power-off of the vehicle; and two-way charging can be moreflexible, and stability of two-way charging is also improved.

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.
