Abstract

The invention relates to a battery early warning fire extinguishing system and a battery system. The battery early warning fire extinguishing system comprises a gas monitoring device and a fire extinguishing device connected with the gas monitoring device. The gas monitoring device is used for being connected to a battery management system in the battery system and sending early warning signals to the battery management system and fire extinguishing start signals to the fire extinguishing device when it is detected that the concentration of characteristic gas emitted by a battery set in the battery system is larger than the preset threshold value. According to the battery early warning fire extinguishing system and the battery system, the gas monitoring device is used for conducting management control over power supply of the battery set, meanwhile, the fire extinguishing device is used for conducting fire extinguishing on failure batteries, so that fire extinguishing is conducted in time, passive safety protection on the battery set is achieved, and running safety of the battery set is guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery protection, in particular to a battery early warning fire extinguishing system and a battery system. Background technique [0002] When the battery system is overcharged or working with high current for a long time, the temperature of the battery pack will rise. In severe cases, thermal runaway may occur, which will endanger the safety of the battery pack. Since many batteries are arranged in close proximity, the heat is easily diffused, causing thermal runaway of other batteries, and such a chain reaction will greatly increase the failure risk of the battery system. [0003] The current use safety of the current battery system is usually monitored through the battery management system (BMS), which is an active safety protection measure. However, as an integrated circuit, the BMS management system has a certain risk of failure. Therefore, how to improve the safety during use of the battery pack,...
