Abstract

The present invention relates to an immersion-liquid-type battery compartment temperature control system comprising an immersion-liquid-type battery compartment; a first cooling pipe; a second cooling pipe; a third cooling pipe; a temperature sensor which is disposed on the battery pack side of the immersion-liquid-type battery compartment and is used for detecting battery pack temperature; and a temperature control unit which receives battery pack temperature signals sent by the temperature sensor to control startup and shutdown of a first cooling loop, a second cooling loop, a third cooling loop or a heating device. The immersion-liquid-type battery compartment temperature control system has excellent temperature control and temperature balancing capability.

Description

technical field [0001] The present application relates to the technical field of battery box temperature control, in particular to a liquid-immersed battery box temperature control system with temperature control and thermal runaway prevention that can be commonly used in various electric vehicles. Background technique [0002] Most of the battery boxes used in existing electric vehicles adopt wind control or water control in terms of temperature control. figure 1 It is a schematic diagram of an existing air-controlled battery box. This air controlled battery box has an inlet 204 and an outlet 206 for temperature controlled air. The air-controlled battery box requires an open space and sufficient intervals between the single batteries, which reduces the space utilization rate and the energy density of the battery box. The open space is easy to cause foreign objects such as dust and liquid to enter, and the deposition of dust reduces heat dissipation. Efficiency, improve th...
