Embodiment Construction

[0032] In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the related drawings. The preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough and complete understanding of the present disclosure is provided.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. T...

Abstract

The invention discloses a power battery fire extinguishing device, a power battery, and a fire extinguishing method of the power battery. The power battery fire extinguishing device comprises a control system, and a lithium battery fire extinguisher, a gas cooling fire extinguisher, a temperature sensor and a smoke sensor electrically connected with the control system. The temperature sensor and the smoke sensor are installed in a tank body of the power battery, and are used for acquiring a temperature signal and a smoke signal in the tank body and transmitting the signals to the control system; the lithium battery fire extinguisher and the gas cooling fire extinguisher are installed on the tank body of the power battery; and the control system is used for controlling the lithium battery fire extinguisher or the gas cooling fire extinguisher according to the temperature signal and the smoke signal. According to the power battery fire extinguishing device, the power battery, and the fire extinguishing method of the power battery, the misjudgment of a fire accident cannot occur easily, the power battery cannot be damaged easily, and the service life of the power supply can be prolonged.

Description

technical field [0001] The invention relates to the technical field of power battery safety, in particular to a power battery fire extinguishing device, a power battery and a power battery fire extinguishing method. Background technique [0002] A power battery is a power source that provides a power source for tools, mostly referring to lithium-ion batteries that provide power for electric vehicles, electric trains, and electric bicycles. Generally, a power battery consists of a large number of battery cells. When a battery cell is short-circuited to generate a high temperature, other battery cells are also prone to short-circuit due to the melting of the diaphragm due to the high temperature, which may cause a fire. Traditionally, when it is detected that the power battery produces a high temperature, a lithium battery fire extinguisher is used to extinguish the fire to prevent a fire. However, sometimes there is a misjudgment of fire. When there is a misjudgment of fire,...
