Abstract

The invention relates to a battery box heat dissipation system and a heat dissipation method thereof. The system consists of a battery box, a control main board, a plurality of heat dissipating devices, a plurality of rotation speed regulators, a plurality of rotation speed sensors, a temperature sensor, and a failure early warning device disposed outside the battery box. Each heat dissipating device is equipped with a corresponding rotation speed regulator to regulate the rotation speed, and each rotation speed regulator is in connection with the control main board. Each heat dissipating device is equipped with a rotation speed sensor for acquiring the rotation speed of the corresponding heat dissipating device. Each rotation speed sensor is connected to the control main board. The temperature sensor is connected to the control main board. The failure early warning device is in communication connection with the control main board. The control main board is connected to a vehicle control unit. The battery box heat dissipation system and the heat dissipation method provided by the invention can automatically adjust the rotation speed of the heat dissipating devices, calculate the compensation coefficient to adjust the balance, and coordinate the heat dissipating devices to achieve optimal heat dissipation efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of battery box heat dissipation, in particular to a battery box heat dissipation system and a heat dissipation method thereof. 【Background technique】 [0002] At present, the electric vehicle industry is developing rapidly, and people's demand for electric vehicles is also increasing. With the popularity of power batteries, fast charging has become a goal that people are constantly pursuing. At present, the battery box is designed as a closed environment. The heat generated by the battery during charging and discharging, and the accumulation of hot and cold expansion air pressure will cause excessive temperature rise, and multiple sets of heat dissipation devices (fans, etc.) inside are turned on for a long time. The damage or failure of a single internal cooling device is unknown, and the local temperatures of multiple groups of multiple internal cooling devices cannot be coordinated, which greatly reduc...
