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.
