Abstract

The invention discloses a battery pack thermal management system for a hybrid automobile. The battery pack thermal management system comprises a path control valve, a battery pack, a primary cooling circuit, a secondary cooling circuit, a preheating device and a thermal management controller, wherein the path control valve comprises an inlet, a first outlet and a second outlet; the battery pack comprises a power battery module, a battery cooling plate, an electronic water pump, a temperature sensor and a first coolant pipeline; the primary cooling circuit comprises a battery heat radiator and a second coolant pipeline; the secondary cooling circuit comprises a third cooling circuit, a compressor, a condenser, an evaporator and a battery cooler, and the battery cooler is positioned on a third coolant pipeline; the preheating device has a charging preheating mode and a driving preheating mode; the thermal management controller is respectively and electrically connected with the path control valve, the electronic water pump, the temperature sensor and the battery cooler. The battery pack thermal management system disclosed by the invention can realize two-stage cooling of the battery pack and solves the problems that a battery cannot discharge at a low temperature and is low.

Description

Technical field [0001] The invention belongs to an automobile power battery, and in particular relates to a thermal management system for a hybrid power automobile battery pack. Background technique [0002] As people's awareness of environmental protection has increased, more and more new energy vehicles have appeared in our lives. Currently, the development of new energy vehicles has two directions. One is a pure electric vehicle, and the other is a plug-in hybrid vehicle. Due to the impact of the cruising range, the use of pure electric vehicles is subject to certain restrictions. Compared with pure electric vehicles, plug-in hybrid vehicles use two sets of power systems, electric motors and engines, which can not only reduce energy consumption, but also ensure unrestricted driving performance. It is currently the most ideal alternative to traditional internal combustion engine vehicles. [0003] Compared with traditional internal combustion engine vehicles, plug-in hybrid ve...
