Problems solved by technology

[0003] The battery disconnect unit (Battery Disconnect Unit, BDU) is a very important electronic control integrated component in the battery system. When the battery disconnect unit is charging and discharging, due to the contact resistance of the heating component (also known as "soft connection") and other components, As a result, a large amount of heat will be generated when there is an excessive current. If it is not discharged in time, the temperature of the heat-generating component will rise sharply, resulting in a high temperature of the entire battery cut-off unit. as a result of

Abstract

Embodiments of the invention provide a heat dissipation system, a battery cut-off unit and a battery system. The heat dissipation system is applied to the battery system comprising a battery module and the battery cut-off unit. The heat dissipation system comprises a liquid cooling circuit, wherein the liquid cooling circuit is in contact with the heating component of the battery cut-off unit andis in communication with the liquid cooling system pipeline in the battery module, and is used for introducing cooling liquid in the liquid cooling system pipeline to cool the heating component by thecooling liquid. According to the heat dissipation system, the battery cut-off unit and the battery system, the thermal management of the heating component in the battery cut-off unit can be realized.

Description

technical field [0001] The present application relates to the field of battery technology, in particular, to a heat dissipation system, a battery disconnect unit and a battery system. Background technique [0002] The power battery system is the core component of pure electric vehicles, which is directly related to the performance of its motors, battery life, and the safe operation of logistics vehicles. [0003] The battery disconnect unit (Battery Disconnect Unit, BDU) is a very important electronic control integrated component in the battery system. When the battery disconnect unit is charging and discharging, due to the contact resistance of the heating component (also known as "soft connection") and other components, As a result, a large amount of heat will be generated when there is an excessive current. If it is not discharged in time, the temperature of the heat-generating component will rise sharply, resulting in a high temperature of the entire battery cut-off unit...
