Currently, lithium ion batteries are the mainstream technology in the field of electric power energy storage, and have the advantages of high energy density, long cycle life at normal temperature, and the like, but the temperature adaptability is poor, the resistance inside the battery can be increased at low temperature, the discharge capacity and the power of the battery can be reduced, and simultaneously, polarization phenomenon can also occur in the charging process. At high temperature, chemical reaction inside the battery is accelerated, and electrolyte and SEI film are easily decomposed, resulting in shortened life of the battery. Therefore, in order to improve the performance of the lithium ion battery at extreme temperatures, a series of optimization measures such as controlling the operating temperature of the battery, optimizing the electrolyte composition of the battery, improving the structure of the battery, etc. are required, wherein the design of the battery pack is particularly important for the function of adjusting the operating temperature of the lithium ion battery (the optimal temperature range is usually 15-35 ℃).
In general, ventilation and heating are mainly considered in the design of a battery pack for energy storage so as to meet the use requirements in high and low temperature environments, for example, patent CN202111104679.5 discloses an energy storage battery pack shell, and through the arrangement of a lower transverse heat dissipation channel, a lower longitudinal heat dissipation channel, an upper transverse heat dissipation channel and an upper longitudinal heat dissipation channel which are mutually communicated, ventilation inside an upper shell and a lower shell is enhanced under the cooperation of a lower air blowing component and an upper air blowing component, so that the heat dissipation speed of the energy storage battery pack is increased, and the heat dissipation effect is improved; patent CN202122139458.3 discloses a heatable battery module, a heating film is arranged on the bottom of the heatable battery module in a pasting manner, the heating film is connected with a power switch, and the heating film is selectively heated in an on/off mode; patent CN201910388368.2 discloses a battery pack design, which is to add an insulation layer around the periphery and at the bottom of the battery pack, so as to reduce the influence of ambient temperature on the battery pack.
However, the heat preservation and heat dissipation measures in the methods often have conflicts in effect, and the existence of the heat preservation layer influences the flow direction and the flow speed of the air duct, reduces the heat conductivity coefficient and influences the heat dissipation of the air duct under the high-temperature condition; meanwhile, the heat insulation layer is difficult to cover the battery in a large area due to the existence of the air channel of the energy storage battery pack, and the heat insulation effect is affected.
