Abstract

The embodiment of the invention provides an immersed liquid-cooled battery system, and relates to the field of energy storage batteries. The immersed liquid-cooled battery system comprises a battery box, a battery cell module and a cooling liquid. The battery box is provided with an accommodating cavity for accommodating the battery cell module; the battery box is provided with a water inlet and a water outlet, the water inlet and the water outlet are both communicated with the accommodating cavity, the water inlet is used for injecting cooling liquid, and the water outlet is used for discharging the cooling liquid, so that the cooling liquid dissipates heat of the battery cell module in a state of immersing the battery cell module. The battery cell module is directly immersed in the cooling liquid, and heat generated in the charging and discharging process of the battery is taken away through flowing of the cooling liquid. The temperature control of the immersed liquid-cooled battery system provided by the invention is more accurate, the temperature difference of the battery system is smaller, the consistency of the battery system is improved, and the service life is prolonged. Meanwhile, the battery system is directly immersed in the cooling liquid, so that the risks of thermal runaway and thermal diffusion of the battery system can be reduced, and the safety of the battery system is effectively improved.

Description

technical field [0001] The invention relates to the field of energy storage batteries, in particular to a submerged liquid-cooled battery system. Background technique [0002] Air cooling is a heat dissipation method that uses low-temperature air as the medium, and uses cold air to contact the surface of the battery for heat exchange, thereby reducing the temperature of the battery. The structure of the air cooling system is relatively simple, the technology is relatively mature, and the cost is low. However, due to the low thermal conductivity of the air, the heat that can be taken away is limited, and the heat exchange efficiency is low, resulting in uneven internal temperature of the battery system, and it is difficult to achieve more accurate control of the temperature of the battery system. [0003] Liquid cooling is a heat dissipation method that takes away the heat generated by the battery and reduces the temperature of the battery through liquid convection heat exch...
