Abstract

The invention relates to a safety protection system of a battery system and the battery system. The safety protection system comprises a gas monitoring device; the gas monitoring device is used for being connected to a battery management system and sending an early warning signal to the battery management system when it is detected that the concentration of characteristic gas exhausted out of battery packs in the battery system is larger than the first preset threshold value; the battery management system is connected to a vehicle control unit and a high-voltage compartment of the battery system, and the high-voltage compartment is connected with the battery packs to form a controlled circuit; the battery management system is used for sending the early warning signal to the vehicle control unit when receiving the early warning signal; and the vehicle control unit is used for emitting an instruction used for cutting off an inner circuit of the high-voltage compartment through the battery management system when receiving the early warning signal so that the controlled circuit can be disconnected. The safety protection system is used for managing and controlling the battery failure risk in real time, autonomous connection and disconnection can be conducted when the failure risk exists, the passive safety protection for the battery packs is achieved, and safe operation of the battery packs is ensured.

Description

technical field [0001] The invention relates to the technical field of battery protection, in particular to a battery system safety protection system and the 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, espec...
