Abstract

The invention provides a battery power system, a vehicle and a control method; the battery power system comprises the following parts: a driving module which is used for driving the vehicle; a plurality of battery packs used for supplying power to the driving module; multiple first switching devices, wherein each battery pack is connected with the driving module through one first switching device;any one of the plurality of battery packs is used as a main battery pack to supply power to the driving module through closing of the first switching device connected with the main battery pack, andthe other battery packs are redundant and standby when the first switching devices connected with the other battery packs are disconnected, or supply power to the driving module together with the mainbattery pack when the first switching devices connected with the other battery packs are closed. Through the technical scheme of the invention, the power supply of the whole vehicle is provided through the independent power supply of the main battery pack under a conventional working condition, and the normal work of the vehicle is ensured; and the redundant standby battery packs and the main battery pack can be combined together to increase the electric quantity under a special working condition, so that the vehicle can still work normally under the special working condition.

Description

technical field [0001] The present invention relates to the technical field of vehicle equipment, in particular, to a battery power system, a vehicle and a control method. Background technique [0002] Electric vehicles generally use a fixed set of battery packs to provide power. The battery pack is composed of many battery modules or battery cores. The battery system also includes a high-voltage power distribution protection device and a battery management system (BMS). The battery pack has a fixed Platform voltage, power, charge and discharge and other parameters to match the vehicle’s working conditions; when the battery fails or the battery capacity needs to be increased to adapt to different vehicle working conditions, it is necessary for the battery to have a redundant system, and it can be quickly and automatically switch. [0003] In the prior art, due to the limitation of battery voltage consistency characteristics, special working conditions need to increase the p...
