In order to reduce the temperature of the battery and improve its thermal safety during use, this paper tentatively designs an oil-immersed battery thermal management system to validate the feasibility of the insulating oil on cooling the discharging battery. Through a series of experiments, the dielectric property of the transformer oil and silicon oil is further confirmed, and their cooling effectiveness is superior to the natural convection. Specifically, the insulating oils not only control the battery temperature below 35 ℃, but also thermally homogenize the battery with temperature differences below 3 ℃ in the discharge rate ranging from 1 to 2 C. Furthermore, both the cooling and homogenization performances demonstrate that the transformer oil is better than silicon oil. This work experimentally demonstrates the performance of silicon oil and transformer oil for cooling the battery, and the feasibility of self-designed oil-immersed battery cooling system is also verified, which can provide effective guidance for the development of higher-efficient direct-contact liquid cooling system in the future.
