Abstract

The invention discloses a battery fire disaster early-warning device which comprises a detector and a data concentrator. The battery fire disaster early-warning device is characterized in that the detector comprises a first upper cover, a first lower cover, an installation support and a first circuit board located between the first upper cover and the first lower cover, a first control chip, a sensor, a first filtering capacitor, a first communication interface and a first interface chip are integrated on the first circuit board, the data concentrator comprises a second upper cover, a second lower cover and a second circuit board located between the second upper cover and the second lower cover, and a second control chip, an upgrading interface, a second filtering capacitor, a second communication interface and a second interface chip are integrated on the second circuit board. The lithium ion battery fire disaster early-warning device is independent in a BMS, the out-of-control stateof a power battery can be detected, an alarm is given as soon as possible, and an internal small fire extinguisher can be automatically started for primarily suppressing fire behaviors.

Description

technical field [0001] The invention relates to a battery fire warning device. Background technique [0002] In recent years, the new energy automobile industry has grown rapidly, and the accompanying power battery has grown synchronously. At present, most power batteries are lithium-ion batteries. Their safety is a pain point. Overcharging, over-discharging, and high temperature may cause fires. Practical applications There have also been many fire accidents. Power batteries are equipped with BMS (Battery Management System), which can monitor the voltage, current, and temperature of the battery, and automatically manage charge and discharge and over-temperature protection. However, if the control fails due to conditions such as BMS system failure, it may cause an accident. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a battery fire warning device. [0004] The present invention is a...
