Embodiment 1

[0030] figure 1 A schematic diagram of a fire handling device for a power battery pack of an electric vehicle according to an embodiment of the present invention is shown. The power battery pack is set in the battery box of the electric vehicle, figure 2 A schematic side view of a battery box of an electric vehicle according to an embodiment of the present invention is shown.

[0031] according to figure 1As shown, the device includes a first temperature sensor 10 , a second temperature sensor 20 , a smoke sensor 30 , a flame sensor 40 , an alarm device 50 and a controller 60 .

[0032] The first temperature sensor 10 is arranged on the shell of the battery box and is used to detect the temperature of the battery box. Optionally, the first temperature sensor 10 is arranged inside the shell of the battery box to prevent the sensor from being squeezed and damaged during the handling of the battery box; at the same time, being set inside the shell can more accurately obtain ...

Abstract

The invention discloses a fire treatment apparatus and method for a power battery pack of an electric vehicle. The fire treatment apparatus comprises a first temperature sensor, a second temperature sensor, a smoke sensor, a flame sensor, an alarm apparatus and a controller, wherein the first temperature sensor is arranged on the shell of a battery box body and used for detecting the temperature of the battery box body; the second temperature sensor is arranged on a single battery of the power battery pack and used for detecting the temperature of the single battery; the smoke sensor is arranged on the inner side of the top cover of the battery box body and used for detecting whether smoke exists in the interior of the battery box body or not; the flame sensor is arranged on the inner side of the top cover of the battery box body and used for detecting whether flame exists in the interior of the battery box body or not; the alarm apparatus is used for giving out an alarm; and the controller is connected with the sensors and the alarm apparatus separately and used for controlling the alarm apparatus to give out an alarm according to detection signals of the sensors. By virtue of the fire treatment apparatus and method, the temperatures, smoke and flame conditions in the power battery pack can be detected in real time, and an alarm can be performed in case of an abnormal condition, so that a solution can be adopted by a related working staff in time conveniently.

Description

technical field [0001] The invention relates to the technical field of electric vehicle safety, in particular to a fire handling device and method for a power battery pack of an electric vehicle. Background technique [0002] With the continuous increase of automobile usage, fuel consumption will intensify and consume oil reserves, which will inevitably cause an energy crisis. At the same time, the exhaust gas emitted by automobiles pollutes the air, deteriorates the environment, and destroys the ecological balance. As a result, environmentally friendly electric vehicles have emerged at the historic moment. While the technology of electric vehicles has been further developed, a considerable number of electric vehicles have been put into production. [0003] Under normal driving conditions, the possibility of fire accidents in electric vehicles is very small, but compared with traditional vehicles, the added battery also increases the dangerous system of electric vehicles. ...
