Currently, liquid cooling is the most widely used solution for managing battery temperatures due to its technical effectiveness, ability to dissipate heat, and cost-effectiveness. Transverse flow and series connection are mostly employed for the heat dissipation of cylindrical battery packs that are either liquid-cooled or air-cooled.
Additionally, the simulation and test results demonstrate that the liquid cooling solution can restrict the battery pack’s maximum temperature rise under the static conditions of a continuous, high-current discharge at a rate of 3C to 20 °C and under the dynamic conditions of the New European Driving Cycle (NEDC) to 2 °C.
For liquid cooling of cylindrical cells, all methods proposed or in use today require a certain gap between all the individual cells in the diameter direction to allow a coolant flow path to pass through, which undoubtedly increases the size of the battery pack and reduces its volumetric energy density.
Lightweight design: For the vehicle to be lightweight, the design of the liquid cooling system also focuses on weight reduction. The use of lightweight materials and structural optimization can reduce the weight of the system and improve the overall performance of the battery system.
In the simulation model, the coolant inlet flow of the battery pack is set at 0.2 L/min, which is equal to the flow used in the test. The initial temperature is adjusted to the ambient temperature during the test, 22.6 °C.
Effect of coolant flow rate on heat dissipation performance of longitudinal-flow battery pack Under the current cooling water flow rate and the thermal power rate of the TDCs, the maximum temperature of TDCs does not exceed 40 °C, but the maximum end temperature exceeds 40 °C.
