Abstract

The invention relates to a battery system and a safety protective system therefor. The safety protective system comprises a gas monitoring apparatus, a power battery, a control switch and a relay, wherein the gas monitoring apparatus is connected with the control switch and used for controlling the control switch to be disconnected when it is detected that the concentration of a characteristic gas emitted from a battery pack in the battery system is greater than a first preset threshold value, or otherwise, the control switch is controlled to be closed; the control end of the relay, the power supply and the control switch are connected to form a control loop; and the controlled end of the relay is suitable for being connected with the battery pack in the battery system and a high-voltage box in the battery system to form a controlled loop. By virtue of the safety protective system, real-time management and control on the failure risk of the battery can be performed; and when failure risk exists, automatic on and off can be realized, so that passive safety protection on the battery pack is achieved, and safety operation of the battery pack is guaranteed.

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...
