Problems solved by technology

It is also worth noting that under normal conditions, the above thermal management methods can control the temperature rise of the power battery to a certain extent, but the temperature uniformity effect is not ideal, and the ability to suppress the spread of local thermal runaway induced by abnormal factors is poor

Abstract

The invention provides a vibration-enhanced battery thermal management and thermal safety protection device, comprising: a battery module, consisting of several battery cells connected in series and encapsulated in a sealed shell, the top of the sealed shell is provided with an interlayer, so A sublimation material with high thermal conductivity and high latent heat is encapsulated in the interlayer; a lower battery box; the battery lower box has a non-conductive liquid working medium, and the liquid working medium immerses the battery module; an upper cover plate is provided with On the top of the battery lower box; and a condenser, a vibration amplifier is provided on the opposite two side walls of the condenser, and the condenser is connected to the battery lower box through an air duct and a liquid return pipe. The invention effectively solves the problems of temperature control, temperature uniformity and thermal runaway spread inhibition of the power battery, and has better thermal runaway early warning capability.

Description

technical field [0001] The invention relates to the technical field of power battery thermal safety, in particular to a vibration-enhanced battery thermal management and thermal safety protection device. Background technique [0002] The development of new energy vehicles is an important measure for the automobile industry to save energy and reduce emissions, alleviate environmental problems, and achieve sustainable development. However, the thermal sensitivity and thermal safety of power batteries seriously restrict the further development of new energy vehicles. On the one hand, excessive temperature and uneven temperature distribution will reduce the cycle life, endurance and power performance of the power battery; on the other hand, excessive temperature is an important cause of thermal runaway, which can be released after single thermal runaway or partial thermal runaway. The large amount of energy causes the rapid spread of heat, which leads to the fire and explosion o...
