Rapidly cooled lithium battery module

Abstract

The invention discloses a rapidly cooled lithium battery module which comprises a temperature probe, a connecting plate, a lithium battery pack, an aluminum shell, a semiconductor refrigerator, a heatradiator and a fan, wherein the semiconductor refrigerator is sandwiched between the aluminum shell and the heat radiator; the refrigeration surface of the semiconductor refrigerator contacts the lower surface of the aluminum shell; the semiconductor refrigerator is matched with the temperature probe. As the lithium battery pack is mounted inside the aluminum shell, the lithium battery pack can be effectively protected, the structure is stable and reliable, single lithium batteries are sandwiched between aluminum fins and side walls of the aluminum shell respectively; the temperature of the lithium battery pack can be monitored by the temperature probe above the connecting plate; when the temperature is too high, the semiconductor refrigerator starts to refrigerate, and the temperature ofthe lithium battery pack is rapidly reduced by the semiconductor refrigerator through the aluminum shell and the aluminum fins, so that the service life of the lithium battery pack is prolonged, thelithium battery pack is prevented from explosion because of too high temperature, thermorunaway can be delayed, and the escape rate of operators can be greatly increased.

Description

【Technical field】 [0001] The invention relates to the technical field of lithium ion batteries, in particular to the technical field of rapidly cooling lithium battery modules. 【Background technique】 [0002] The existing lithium-ion battery market has become increasingly mature, and the scale of various manufacturers is also increasing. The advantages of lithium batteries are gradually reflected. However, lithium batteries will accelerate aging under high temperature conditions, and their service life will be greatly reduced. It will cause the lithium battery to explode, which will not only affect the normal use of the equipment, but also cause casualties. The existing grouping process of lithium batteries is fixed by the combination of components. The safety of lithium batteries is more difficult to control. In the early stage of thermal runaway, the temperature of the battery cells rises rapidly. Personnel escape time shortened. Therefore, the application number: 201610...
