Embodiment Construction

[0009] figure 1 Shown is an embodiment of a battery pack module of the present invention, wherein the battery pack module of the present invention includes a plurality of single cells 6 and a temperature regulation system, the temperature regulation system includes a pump 1, a temperature regulator 2, a flow channel 3 and fluid medium. The fluid medium is filled in the flow passage 3, one end of the flow passage 3 is connected with the pump 1 to the inlet 4, and extends through the temperature regulator 2, the other end of the flow passage 3 is connected to the pump 1 and the outlet 5, and the fluid medium is in The circulation channel 3 flows in the direction indicated by the arrow, thereby forming an internal circulation structure of the fluid medium. The fluid medium is pressurized and extruded by the pump 1, and then passes through the circulation channel 3 after being adjusted by the temperature regulator 2. The temperature regulator 2 is used for The fluid medium in the...

Abstract

The invention relates to a battery pack module comprising a temperature regulating system and a plurality of monomer batteries or a plurality of battery packs, wherein the temperature regulating system comprises a pump, a temperature regulator, a circulating passage and fluid media, wherein the fluid media are filled in the circulating passage; the circulating passage is connected with the inflow entrance of the pump and is connected with the inflow entrance of the pump, thereby forming a circulation loop of the fluid media; and the temperature regulator is used for enabling the fluid media in the circulating passage to be heated or cooled so as to heat or radiate the monomer batteries or the battery packs arranged around the circulation loop. The temperature regulating system of the battery pack can provide constant high-efficiency temperature regulating for the battery packs.

Description

technical field [0001] The present invention relates to a battery pack, and more particularly to a temperature regulating system for a battery pack. Background technique [0002] The battery will generate a lot of heat during charging and discharging. This heat will not only affect the performance of the battery, but more seriously, when the heat accumulates to a certain extent, it may cause thermal runaway and explosion. For lithium-ion battery packs used in automobiles, heat dissipation is very necessary. In the prior art, external circulation is usually used to dissipate heat from the battery pack, for example, by blowing cold air from the outside of the battery pack module to the battery pack, and discharging the air passing through the battery pack to the outside of the battery pack module. A large cycle is formed externally. This heat dissipation method usually brings moisture in the external air into the battery pack module, which is not conducive to the stable oper...
