Table 1 indicates the solutions adopted for battery cooling for the new energy vehicles in recent years. According to the data in the table, liquid cooling is the primary technological solution applied to the battery thermal management system for new energy vehicles.
A parallel configuration of a power battery cooling refrigerant-based, and an AC system was set up to study the dual system's cooling performance and control dynamics. The study involves an integrated thermal management system of pure electric vehicles and covers data transfer, control strategy execution, and control programs.
Few studies have been on synergistic control that combines power battery cooling based on refrigerant and the AC system. Due to the two-phase heat transfer involved, thermal management systems for refrigerant directly cooling batteries via cold plate need complex control logic.
Therefore, the current lithium-ion battery thermal management technology that combines multiple cooling systems is the main development direction. Suitable cooling methods can be selected and combined based on the advantages and disadvantages of different cooling technologies to meet the thermal management needs of different users. 1.
