Abstract

The invention relates to a power battery system and a vehicle. The power battery system comprises a first battery pack (1) and a second battery pack (2); a first coolant pipeline (11) is formed in thefirst battery pack (1); the second battery pack (2) is electrically connected with the first battery pack (1); a second coolant pipeline (21) is formed in the second battery pack (2), wherein the second coolant pipeline (21) is connected with the first coolant pipeline (11) in parallel; and the flow of the coolant which flows through the first coolant pipeline (11) and the second coolant pipeline(21) is adjustable. Therefore, the battery electric quantity and the cruising power of the vehicle can be increased and improved; and in addition, by regulating the flow of the coolant which flows through the two coolant pipelines, the temperatures of the two battery packs can be flexibly adjusted and controlled correspondingly and the cooling efficiency is improved effectively, thereby prolonging the service lives of the battery packs, giving full play to the maximum output capabilities of the two battery packs, and improving the power performance of the finished automobile.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a power battery system and a vehicle. Background technique [0002] At present, most pure electric vehicles at home and abroad use a battery pack as a power source. The battery pack is mostly located in the middle of the chassis. The layout space and arrangement of the battery pack are single, the power is low, and the driving range is short. Moreover, most of the battery packs adopt cooling methods such as natural cooling or air cooling, which are not enough to meet the heat dissipation requirements of the battery pack when the car is driving at high speed or accelerating, which will cause the battery pack to overheat, thereby affecting the service life of the battery pack And vehicle power performance, even there are potential safety hazards. Although it is possible to reduce the output power of the battery pack to prevent the battery pack from overheating, this will redu...
