Battery thermal runaway monitoring, preventing and safety protecting system

Abstract

The invention discloses a battery thermal runaway monitoring, preventing and safety protecting system, which relates to the technical field of battery safety. The system comprises a high-temperature alarm monitoring part, a thermal runaway prevention and rescue part, a thermal runaway safety protection part, a power supply and a controller, wherein the battery is respectively connected to the high-temperature temperature monitoring chain and the prevention and rescue temperature monitoring chain, a pressure monitoring device of the thermal runaway safety protection part is arranged on a connecting circuit of the thermal runaway prevention and rescue part; and an audible and visual alarm, a driving pump of the thermal runaway prevention and rescue part and a fire extinguishing system are respectively connected with the controller. Monitoring, prevention and safety protection of all batteries are realized; when the temperature of any battery reaches a set temperature T1, an automatic audible and visual alarm is given; when the temperature of any battery reaches a set temperature T2, thermal runaway prevention and rescue measures are automatically started, further development of thermal runaway is prevented; and when the pressure of any battery reaches the set pressure P1, thermal runaway safety protection measures are automatically started, so that the safety of the battery is improved.

Description

technical field [0001] The invention belongs to the technical field of battery safety, in particular to a monitoring, prevention and safety protection system for battery thermal runaway. Background technique [0002] The energy storage system can not only cut the peak and fill the valley, effectively alleviate the fluctuation of new energy and the rate of power abandonment, but also the power source of new energy vehicles. As one of the core parts of the energy storage system, the battery's safety is highly recognized by all sectors of society. Attach great importance to it. At present, most of the monitoring, prevention and safety protection of battery thermal runaway have limitations. There are few monitoring and collection signals, a single early warning mode, and the accuracy is not high enough. The early warning response is lagging behind, and there are no supporting thermal runaway rescue measures . Contents of the invention [0003] Aiming at the above-mentioned te...
