Why do lithium ion batteries need to be connected in series?
To meet the power and energy requirements of the specific applications, lithium-ion battery cells often need to be connected in series to boost voltage and in parallel to add capacity . However, as cell performance varies from one to another [2, 3], imbalances occur in both series and parallel connections.

FAQs about Research on direct cooling and heating technology of battery cabinet
How does a direct-cooling battery thermal management system work?
In vehicles, the direct-cooling battery thermal management system usually connects the battery cooling plates parallel to the vehicle air conditioning evaporator, forming a cooling system with two evaporators with different cooling requirements.
Can a refrigerant-based battery thermal management system be used for electric vehicles?
A novel electric vehicle thermal management system based on cooling and heating of batteries by refrigerant Energy Convers. 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.
