Abstract

The invention discloses an automatic fire extinguishing system for a power battery system of a passenger vehicle and a control method of the automatic fire extinguishing system, and belongs to the technical field of automobile safety fire-fighting. The automatic fire extinguishing system comprises an air conditioner cooling sub system and an automatic fire extinguishing sub system which is connected to the inner part of the air conditioner sub system, wherein the automatic fire extinguishing sub system comprises a controller, a solenoid valve, a sensor, an alarm and a battery pack; the controller processes received signal data, and outputs an instruction according to processed information; the input end of the solenoid valve is connected to the output end of the controller for receiving afire extinguishing signal output by the controller, so that fire extinguishing is started; the output end of the sensor is connected to the input end of the controller for detecting environment data inside battery pack; the input end of the alarm is connected to the output end of the controller for receiving an alarm signal output by the controller, so that alarm is started; and the battery pack is further connected to a BMS. The automatic fire extinguishing system does not occupy extra size, facilities layout, and improves lightweight level of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile safety and fire protection, in particular to an automatic fire extinguishing system and a control method for a power battery system of a passenger car. Background technique [0002] New energy vehicles are one of the seven strategic emerging industries in my country, and their power sources are battery packs. The safety and reliability of battery packs are particularly critical as the power source of the vehicle. When a short circuit, thermal runaway, high temperature, external force extrusion, puncture, etc. occur inside the battery pack, it is easy to cause thermal expansion of the battery or capacitor, resulting in explosion and combustion. [0003] The traditional solution is to install the automatic fire extinguishing device of the power battery system on the new energy vehicle. The automatic fire extinguishing device host is combined with sensors and fire extinguishing pipes. level of li...
