Abstract

The invention relates to a temperature control system of a power modular battery. The temperature control system is used for performing temperature control on the battery by a phase-change material and a heat-transfer fluid in an electromobile and is characterized by comprising a battery box, and a battery integration module which is arranged in the battery box; the battery box comprises a bottom plate, wing plates vertically connected with two ends of the bottom plate, a fluid temperature control device connected with the bottom plate, and phase-change temperature control devices at the inner sides of the wing plates; the bottom of the battery integration module is in contact with the bottom plate; and the side surface of the battery integration module is connected with the phase-change temperature control devices. Compared with the prior art, the temperature control system is high in energy utilization efficiency, simple in structure, good in applicability and the like.

Description

technical field [0001] The invention relates to the field of power battery management systems for electric vehicles, in particular to a temperature control system for power modular batteries. Background technique [0002] Since the 1990s, as environmental pollution and non-renewable energy crisis have become worldwide problems, the automobile industry has been looking for new breakthroughs to reduce the pressure on environmental pollution and energy consumption. However, electric vehicles have received more research and attention due to their advantages such as high energy utilization efficiency and good environment. In recent years, electric vehicles have made great progress both in technology and in the market. As the power source of electric vehicles, the importance of battery packs to electric vehicles is self-evident. For pure electric vehicles, the cost of the battery accounts for about 1 / 3 of the cost of the vehicle, and the performance, life and safety of the batte...
