Abstract
The battery thermal runaway protection system and the electric vehicle provided by the embodiments of the present invention relate to the technical field of battery thermal runaway protection. The battery thermal runaway protection system is used to perform thermal runaway protection control on battery modules of electric vehicles. Detect whether the module has thermal runaway, and output a corresponding detection signal; the switch circuit connected to the thermal runaway detection board is used to obtain the detection signal, and output a corresponding level signal according to the detection signal; The control device connected to the switch circuit is used to obtain the level signal, and determine whether to perform thermal runaway protection on the battery module according to the level signal. Through the above configuration, the simplicity of battery thermal runaway protection can be improved.
Description
technical field [0001] The present application relates to the technical field of battery thermal runaway protection, in particular, to a battery thermal runaway protection system and an electric vehicle. Background technique [0002] With the continuous enhancement of the concept of low-carbon and environmentally friendly life in society, electric vehicles, as a new type of travel tool, have gradually entered people's daily lives, bringing great convenience to people's lives while avoiding negative impacts on the environment. In order to pursue high energy density and high battery life, the current electric vehicles reduce the thickness of the separator in the battery, which poses a certain safety hazard to the battery safety and can easily cause thermal runaway. For lithium-ion batteries, when the temperature is too high or the charging voltage is too high, it will cause many potential exothermic side effects, and if the heat is not dissipated, it will cause the battery tem...
