Regarding heat dissipation issues of Ni-MH battery pack
The heat dissipation problem of Ni-MH battery pack has always been one of the key technologies in the industry. Lithium-ion batteries have higher energy density and larger charge and discharge rates than traditional lead-acid batteries, nickel-cadmium batteries, and nickel-metal hydride batteries, so they generate serious heat during operation;
Especially in the field of power lithium-ion batteries, where road conditions are complex and the environment is harsh (especially in high-temperature summers), the battery generates more heat, which has a more significant impact on battery capacity, life, and especially safety performance.

To a certain extent, the safety problem of lithium-ion batteries is actually its thermal problem. The heat generation rate of the battery is greater than the heat dissipation rate, and the battery pack will heat up. Once the temperature critical point that the battery pack can withstand is exceeded, the electrical equipment will Serious safety accidents occur, so the heat dissipation problem of lithium-ion powered lithium-ion battery packs is crucial.
Lithium-ion powered lithium-ion battery packs will generate a certain amount of heat during the charging and discharging process, especially during large-current charging and discharging, a large amount of heat will occur inside the lithium-ion battery. However, due to the structural characteristics of lithium-ion batteries, different There is a significant difference in thermal conductivity in the direction. The thermal conductivity in the direction parallel to the pole piece is significantly higher than the thermal conductivity in the direction perpendicular to the pole piece. Therefore, different heat dissipation methods not only have significant differences in efficiency. difference.
