Abstract

The invention provides a battery module comprising a casing, battery cells, a heat equalizing plate and a heat dissipating device. The casing includes six panels in the up, down, front, rear, left andright directions respectively. The battery cells are disposed in the casing. The heat equalizing plate is installed in the casing, is sandwiched between the battery cells, and is filled with a heat transfer working medium. The heat dissipating device has heat equalization, heat exchange and heat dissipation functions. The present invention also provides a battery pack having the battery module, an electric vehicle, and a power grid system. The heat equalizing plate filled with the heat transfer working medium can quickly absorb the heat generated during the charging and discharging processesof the battery cells, and distributes the heat to transfer the heat to the heat dissipating device to quickly dissipate the heat inside the battery module. Therefore, it is possible to prevent the insufficient heat dissipation of the battery modules in the battery pack, the electric vehicle, and the power grid system from influencing the normal use or causing a safety accident.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module, a battery pack, an electric vehicle and a grid system. Background technique [0002] During the charging and discharging process of the battery pack, a large amount of heat will accumulate inside the battery. If the heat is not discharged in time, the battery temperature will be too high or the temperature uniformity will be poor, which will not only affect the battery capacity and service life, but also cause Thermal runaway will cause the battery to be disconnected and open, smoke, and even cause the battery to explode. Conversely, if the battery pack is in a low-temperature environment, it will shorten its life, sharply reduce its charge and discharge capacity, and reduce the battery utilization efficiency. Therefore, it is particularly important to control the heat and temperature of the battery. [0003] At present, the heat exchange of battery packs gen...
