Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the present invention includes an alarm display unit, a detection control unit and a fire extinguisher. The alarm display unit and the detection control unit are connected through CAN bus or RS485 bus, and a set of battery thermal runaway state detection and control device includes a display alarm unit and 1 to 256 detection control units, and each detection control unit is connected to control an independent fire extinguisher.

[0031] The alarm display unit is installed in a manned position to display the alarm status of each detection control unit, and when receiving an alarm message from the detection control unit, there will be an audible and visual alarm prompt. At the same time, it provides a manual control injection button for the fire extinguisher. Press and hold for more than 5 seconds to actively control the injection of...

Abstract

The invention relates to a battery thermal runaway state detection control device and method, which are used for detecting and controlling the thermal runaway state of a battery compartment. The device comprises an alarm display unit, 1-256 detection control units and a fire extinguisher, the alarm display unit and the detection control units are connected through a CAN bus or an RS485 bus, and each detection control unit is connected with and controls the independent fire extinguisher. The alarm display unit is installed at a position where people are on duty and displays the alarm state of each detection control unit, and when alarm messages of the detection control units are received, sound-light alarm prompt is given, and the fire extinguisher is controlled to spray a fire extinguishing agent to extinguish fire. According to the method, the fire extinguishing time is early, control can be conducted at the initial stage of thermal runaway, in-cabin fire extinguishing is achieved, the fire extinguishing agent is sprayed multiple times in stages, the fire extinguishing effect is good, and after-combustion can be effectively inhibited.

Description

technical field [0001] The invention relates to a battery thermal runaway state detection and control device and method, which are used for detection and control of the thermal runaway state of a battery cabin (box), and belong to the field of battery safety. Background technique [0002] With the vigorous development of new energy electric vehicles and battery energy storage industries, the application of lithium batteries is becoming more and more extensive. While bringing convenience to people, battery fire incidents also occur from time to time. Lithium battery safety accidents are directly related to the internal components of the battery and the way the battery is used. During the use of the battery, especially the abuse of the battery, such as battery overcharge, overdischarge, external short circuit, extrusion, collision and high temperature, etc., may cause the chemical substances inside the battery to react, causing a large amount of heat to be generated inside the...
