Abstract

The invention discloses a power lithium battery leakage alarm and extinguishment integrated device which comprises a detection module and an extinguishment module. The detection module comprises a gas sensor, a smoke sensor, a temperature sensor and a detection module circuit board. The gas sensor, the smoke sensor and the temperature sensor are connected with the detection module circuit board. The extinguishment module comprises an electric igniter and an S-shaped aerosol fire extinguisher. The electric igniter is connected with the S-shaped aerosol fire extinguisher. The electric igniter is connected with the detection module circuit board of the detection module. The detection module circuit board is connected with a power supply module of a battery management system and a sensor CAN bus. The power lithium battery leakage alarm and extinguishment integrated device can implement online detection, give an alarm and remind a driver and after-sale maintainers to check internal hidden dangers of a power lithium battery set, the power consumption is low, the size is small, and the power lithium battery leakage alarm and extinguishment integrated device is suitable for occasions where fire risk early warning and fire early inhibition are needed for a power lithium battery pack of a pure electric vehicle or a hybrid power vehicle.

Description

technical field [0001] The invention relates to a lithium battery leakage alarm and fire extinguishing technology, in particular to an integrated device for power lithium battery leakage alarm and fire extinguishing. Background technique [0002] New energy vehicles are one of the seven strategic emerging industries in my country. In 2013, four ministries and commissions including the Ministry of Finance and the Ministry of Industry and Information Technology jointly issued the "Notice on Continuing the Promotion and Application of New Energy Vehicles". Promote the application of subsidies, but judging from the implementation effect, the key issue of new energy vehicles is not the subsidy, but the innovation of battery technology, the construction of supporting facilities and the acceptance of consumers, among which the safety and reliability of batteries are particularly critical. [0003] In recent years, the safety of power lithium batteries has been questioned more and mo...
