Abstract

The invention discloses a battery pack cooling arrangement system. The system comprises a main circuit, wherein the main loop comprises a water inlet loop and a water outlet loop; the battery pack cooling arrangement system further comprises a first battery pack, a second battery pack... and an Nth battery pack, wherein N>1, a water inlet of each battery pack is connected with the water inlet loop, a water outlet of each battery pack is connected with the water outlet loop, the main loop further comprises a main water inlet and a main water outlet, the lengths of pipelines between the water inlets of the N battery packs and the main water inlet are sequentially increased, and the lengths of pipelines between the water outlets of the N battery packs and the main water outlet are sequentially decreased. According to the battery pack cooling arrangement system provided by the invention, the water inlet and outlet of the battery pack are arranged in a first-in and second-out mode, and theproblems of water inlet and outlet positions, overall pressure drop, pipeline water pressure and the like of each pipeline are balanced, so that the purpose of averagely distributing cooling liquid flow is achieved, and the cooling effect of each battery pack is basically consistent.

Description

technical field [0001] The invention relates to the field of automobile thermal management, in particular to a battery pack cooling arrangement system. Background technique [0002] Most of the cooling circuits of battery packs on the market are arranged in series or parallel mode. When connected in series, the temperature of each battery pack will be inconsistent and tend to rise gradually, especially when the vehicle runs for a long time in high temperature weather and the number of battery packs When it is more, the temperature of the front battery pack is low, and then the temperature of the battery pack increases sequentially, and the rear battery pack is in a high temperature state for a long time, and there is no cooling effect; when connected in parallel, there will also be temperature inconsistencies among the battery packs. Due to the positional relationship, the battery pack coolant flow in the front is very large, and the battery pack coolant flow in the back is ...
