Manag., 237 ( 2021), Article 114145 System simulation on refrigerant-based battery thermal management technology for electric vehicles Energy Convers. Manag., 203 ( 2020), Article 112176 J. Electrochem.

Why is air-cooling battery thermal management system bad?

Because of the miniature thermal conductivity of air, the air-cooling battery thermal management system has low heat transfer efficiency and insufficient cooling capacity, so it cannot meet the cooling requirements of the battery when the battery is operating at high power.

How does a new air conditioner control battery temperature?

The increased cooling capacity of the air conditioner also means that the ability to control the battery temperature is reduced, leading to an increase in battery temperature. The control effect of the new system proposed in this paper on this supply imbalance is achieved by changing the evaporating pressure, as shown in Fig. 6.

How do evaporator and battery temperature control work?

By regulating the VOV on the evaporator side and the VOV on the cooling plate side of the battery under different conditions, the cabin's and the battery's temperatures are stabilized around their temperature control targets. Fig. 5. Uneven distribution of cooling capacity.

How does a new air conditioner system affect the cooling capacity?

When the battery is operating at a lower heat generation, the new system can increase the evaporating pressure on the battery side and reduce the evaporating pressure on the air conditioner side, thus changing the cooling capacity of the two branches.
