Problems solved by technology

[0003] At present, the temperature control of the power battery box generally adopts the method of air convection to control the temperature inside the battery box, but the temperature control of the air convection method needs to introduce air from outside the box, which brings difficulties to the protection of the battery box. The protection requirement is IP67, and it is difficult to protect the battery box with the solution of using external air to control the temperature

Abstract

The invention provides a temperature control battery box and a temperature control method thereof. The temperature control battery box comprises a controller, a temperature control system and a temperature sensor, wherein the controller controls the temperature control system to operate in one of a heat dissipation mode, a heating mode and a balance temperature mode according to temperature conditions; the temperature control system comprises N heat-conducting plates, a water pump, a cooling water tank, a shunt pipe, a shunt valve, a return pipe, a frequency converter and an induction heater; a first outlet of the shunt valve is connected with an inlet of the cooling water tank; a second outlet of the shunt valve is connected with an inlet of the water pump; when the temperature control system operates in the heat dissipation mode, liquid is introduced into the cooling water tank through the first outlet of the shunt valve; when the temperature control system operates in the heating mode and the balance temperature mode, liquid flows back to the water pump through the second outlet of the shunt valve. The temperature control battery box can be designed into a totally sealed box according to a conduction heat transfer principle; by adoption of the conduction heat transfer, the heat transfer efficiency is high, and the temperature is rapidly regulated.

Description

technical field [0001] The invention relates to a battery box, in particular to a battery box for realizing automatic temperature control and a temperature control method thereof. Background technique [0002] At present, after years of demonstration operation, the technology of pure electric vehicles has been continuously improved, and the problems that were not noticed at the initial stage have gradually become clear. In order to ensure the safe and reliable operation of the power battery, it is necessary to control the temperature of the battery box so that the power battery always works at an appropriate temperature. within the range. [0003] At present, air convection is generally used to control the temperature of the power battery box to control the temperature inside the battery box. However, air convection is used to control the temperature of the battery box. Air is introduced from outside the box, which brings difficulties to the protection of the battery box. T...
