New energy power battery box fire extinguishing system and fire extinguishing method thereof

Abstract

The invention provides a new energy power battery box fire extinguishing system and a fire extinguishing method thereof and relates to the technical fields of power battery safety monitoring and fire extinguishing. The system comprises a monitoring control module and a sensor connected with an input end of the monitoring control module; and an output end of the monitoring control module is connected with input ends of at least two fire extinguishing devise and an input end of a CAN bus. According to the invention, the new energy power battery box fire extinguishing method is simple, and with adoption of the method, integral security data of a battery box can be reliably obtained in real time, the safety problem of the power battery box caused by overcharging, high temperature, puncture and the like can be monitored in real time, and the problem of lack of a protective measure during a time slot from an early warning of a battery thermal failure initial stage to a thermal failure occurrence is effectively solved.

Description

technical field [0001] The invention relates to the technical field of power battery safety monitoring and fire extinguishing, in particular to a new energy power battery box fire extinguishing system and a fire extinguishing method thereof. Background technique [0002] In recent years, the safety of power lithium batteries has been questioned more and more. The promotion and application of pure electric vehicles and hybrid vehicles has led to an increase in vehicle spontaneous combustion incidents. Since 2015 alone, there have been 8 new energy bus fire incidents, such as Xiamen The bus spontaneous combustion incident led to the serious consequences of burning more than a dozen vehicles and the death of one person, causing greater losses and negative impacts on vehicle manufacturers and battery manufacturers. [0003] In view of the potential safety hazards of power lithium batteries, on August 1, 2015, the Ministry of Transport implemented the industry standard JT / T325-20...
