Battery box of new energy automobile and control method of battery box

Abstract

The invention provides a battery box of a new energy automobile and a control method of the battery box. According to the battery box of the new energy automobile and the control method of the battery box, in the aspect of the device, a plurality of temperature sensors are arranged in the battery box, and two sets of cooling devices and a set of heating device are arranged at the same time. When the average temperature value detected by the temperature sensors is too high, the first cooling device is started, and when the average temperature value detected by the temperature sensors is too high and the temperature of a certain position is obviously abnormal, the second cooling device is started, and the rapid cooling effect is achieved. When the indoor temperature and the outdoor temperature are low, the heating unit needs to be started and operates at a low heating power value, and when the average temperature value detected by the temperature sensors is too low, the heating unit needs to be operated at a high heating power value so that the requirement for normal charging of the battery can be met. According to the battery box of the new energy vehicle and the control method of the battery box, timely and accurate two-way temperature control is provided, and the system risk of the new energy vehicle is reduced while the battery is protected.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery box of a new energy vehicle and a control method thereof. Background technique [0002] New energy vehicles mainly include hybrid vehicles and pure electric vehicles. Among them, pure electric vehicles are vehicles that use a single battery as an energy storage power source. Drive the electric motor to run, thereby propelling the car to move. Batteries are the core of new energy vehicles, and the quality of batteries directly affects the performance of new energy vehicles. The battery generally needs to be placed in the battery box of the new energy vehicle to achieve the purpose of protecting the battery. [0003] However, the airtight structure of the battery box tends to increase the difficulty of temperature control of the battery. When the car runs at high speed for a long time, it consumes a lot of power, forcing the battery plate to react violently...
