Abstract

The invention discloses a battery pack heat management device by employing a liquid medium. The device has a perfect battery pack heat management function, and according to the device, the heating and radiating of a battery pack can be finished, so that the battery pack always works in an optimal temperature range, the temperature of each battery unit can be accurately managed, and the time required for heating the battery pack is obviously shortened; and therefore, the consistency and good performance of the battery pack can be well guaranteed. The battery pack heat management device employing the liquid medium mainly comprises a liquid cooling box, an electronic fan, a liquid medium, a thermostat, a secondary liquid tank, a semiconductor and temperature sensor unit, a battery box temperature sensor, a battery unit, an outer battery box shell, a battery box insulation layer, an inner battery box shell, an electric pump, a battery management unit, a heating module and the like.

Description

technical field [0001] The invention belongs to the technical field of batteries, and relates to a heat management device for a battery pack, in particular to a heat management device for a battery pack using a liquid medium. Background technique [0002] With the continuous development of electric vehicle technology and key component technology, vehicle electrification has become the development trend of the global automotive industry, and pure electric vehicles and other vehicles that are mainly driven by electric energy have become the main development trend in my country. [0003] In recent years, lithium-ion power battery technology has made significant progress. Among the many types of lithium-ion batteries, lithium iron phosphate batteries are mainly used in my country. [0004] In terms of single performance parameters, it can basically meet the requirements of electric vehicles. However, due to the consistency problems in the production and use process, the battery ...
