An electric vehicle battery anti-spontaneous combustion system

Abstract

The invention discloses an anti-self-ignition system for an electric vehicle battery, comprising a battery box and a wind collecting cover connected with the battery box; a plurality of longitudinally extending battery pack slots are arranged in the battery box at horizontal intervals, and adjacent battery pack slots are formed between adjacent battery pack slots. The airflow channel is provided with ventilation pipes. The ventilation pipes run through the front and rear ends of the battery box. The air collecting hood includes a fixed air collecting part, a rotating air guide part and a driving motor. The air part is connected with cold air pipes near both ends, and the cold air pipes are connected with the air outlet of the refrigerator to guide the cold air provided by the refrigerator into the air collecting hood. Each battery pack slot is provided with multiple battery positions, and each battery position is installed with A battery and a temperature sensor that detects the temperature of the corresponding battery, all batteries are connected in parallel, and a temperature control switch is connected to the lead wire of each battery. The system uses air cooling, which can effectively prevent the battery from being caused by excessive current, voltage and temperature. Spontaneous combustion.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, in particular to a self-ignition prevention system for electric vehicle batteries. Background technique [0002] In the newly emerging electric vehicles, spontaneous combustion occurs from time to time, and the occurrence of spontaneous combustion can easily cause personal casualties and economic losses to vehicle owners. For the spontaneous combustion of electric vehicles, the reasons are: [0003] Due to the improved battery life, electric vehicles use more batteries. If the series voltage of the batteries is high, and if the parallel current is large, once a short circuit occurs, the car will inevitably ignite spontaneously. [0004] The electric vehicle battery will increase the temperature when charging, especially in hot summer, when the temperature rises to a certain height, the circuit insulation material of the battery will fail, causing the circuit to short circuit a...

Problems solved by technology

[0007] Although the above-mentioned patent can solve the technical problem of lowering the battery temperature and further avoiding self-explosion, the above-mentioned patent uses liquid for heat exchange and cooling, and additional water pumps are required, so it is still relatively complicated to apply to electric vehicles
