Abstract

The invention provides a soft package battery system with liquid cooling. The soft package battery system comprises a battery body and a battery box, wherein the battery body comprises a plurality of battery cell modules, the battery body is placed in the battery box, and a mounting gap is formed between every two adjacent battery cell modules; a liquid cooling assembly is fixed on the battery body and comprises a bottom cold plate and side cold plates, the bottom cold plate is provided with a plurality of side cold plates, and the plurality of side cold plates are inserted into the mounting gaps, so that the two side surfaces of the battery cell modules are attached to the second heat-conducting silica gel of the adjacent side cold plates, and the bottom surfaces of the battery cell modules are attached to the first heat-conducting silica gel on the bottom cold plate. Through heat dissipation of the bottoms and the side surfaces of the battery cell modules, the structural design that the plurality of side cold plates are matched with the bottom cold plate, and the design of the cold plate flow channels, the temperature distribution uniformity can be effectively improved on the premise of meeting high-rate charging and discharging, and the problem that the design space of a battery system is limited can also be solved.

Description

Technical field[0001]The present invention relates to a liquid-cooled soft-clad battery system belonging to the technical field of thermal management of lithium ion batteries.Background technique[0002]The uniformity of internal temperature distribution in the soft bag battery system has always been difficult to design the soft bag battery system. The difference between the dielectric core is continuously expanded due to the unevenness of the temperature distribution, and the consistency of the electrical core and the battery module will deteriorate, accelerate the battery. Failure; prior art cooling mode for soft bag battery system is mainly air-cooled and liquid cold; the air-cooled mode is the radial heat dissipation of the battery to realize the radial heat dissipation of the battery through the heat exchange of the air flow path in the system, has a certain extension After the lowness, the heat dissipation efficiency is low, and the temperature distribution uniformity in the sys...
