Problems solved by technology

In some cases, this structure has the problem that the power of the energy storage battery pack cannot meet the power requirements of the external electrical appliances at that time, or the power of the driving battery pack cannot meet the current driving requirements. The power distribution management system of electric vehicles cannot realize the coordinated management of the two battery packs, and switch and distribute the two battery packs according to their respective remaining power. The existing body-mounted energy storage battery packs cannot be used to drive the chassis to achieve driving acceleration. range, it cannot improve the cruising range; at the same time, the driving battery pack cannot be used for external power supply of the bodywork, and it is impossible to meet the extreme power consumption conditions of the bodywork.

Abstract

The invention provides a power distribution management system and a management method for a special electric power vehicle, and relates to the field of electric automobile control. A first charger is connected with a first BMS (battery management system) through a third CAN (controller area network) bus, the first BMS is connected with an energy storage battery pack, the first charger transmits data to the first BMS of the energy storage battery pack through the third CAN bus, a second charger is connected with a second BMS through a first CAN bus, the electric quantities of the second BMS and a driving battery pack are managed and distributed, and the second BMS and the driving battery pack supply power for an upper electric device and a chassis electric device. Therefore, power of a dual-power electric automobile is distributed and managed, battery management system data positioned at different CAN bus networks can be forwarded in a bus routing manner, and BMS power can be managed.

Description

technical field [0001] The invention relates to the field of special power supply vehicles, in particular to a power supply distribution management system and management method for electric special power supply vehicles. Background technique [0002] Pure electric special-purpose power vehicles generally use a driving battery pack for driving, and an energy storage battery pack for powering external electrical appliances on the body. In some cases, this structure has the problem that the power of the energy storage battery pack cannot meet the power requirements of the external electrical appliances at that time, or the power of the driving battery pack cannot meet the current driving requirements. The power distribution management system of electric vehicles cannot realize the coordinated management of the two battery packs, and switch and distribute the two battery packs according to their respective remaining power. The existing body-mounted energy storage battery packs c...
