Abstract

The invention discloses an automotive power battery air cooling system, a control method thereof and an automobile with the air cooling system. The air cooling system is simple in control strategy, simple in structure and capable of effectively lowering the internal temperature difference of an automotive power battery pack. The control method includes: when a first preset condition is met, the automotive power battery air cooling system is started; after the automotive power battery air cooling system is started, the cooling process of the automotive power battery air cooling system comprises a first step and a second step which circulate in a reciprocating manner; in the first step, when a second preset condition is met, cooling air enters a battery box through the first ventilation port of the battery box and flows out through the second ventilation port of the battery box, and the first ventilation port and the second ventilation port are respectively located at two ends of the battery box; in the second step, when a third preset condition is met, the cooling air enters the battery box through the second ventilation port and flows out through the first ventilation port.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method for an air-cooling system of a power battery for a vehicle, an air-cooling system for a power battery for a vehicle, and an automobile provided with the air-cooling system. Background technique [0002] The battery system is a key component of new energy vehicles. Overheating of battery cells or excessive temperature difference between internal cells will affect the service life and efficiency of the battery. Taking the temperature difference as an example, the heating power of each cell in the battery system is different, and the heating and cooling environment is different, which will cause uneven temperature distribution of the battery pack. The uneven temperature distribution of the battery pack will cause the power imbalance of all monomers, thereby reducing the performance of the battery pack and the whole vehicle. [0003] Generally, in order t...
