Problems solved by technology
[0002] Among all external environmental factors, temperature parameters have the greatest impact on the charging and discharging performance of lithium batteries, except that low-temperature charging and discharging may cause damage to 72v lithium batteries and high-temperature charging and discharging may cause accelerated battery aging and affect life. The charging and discharging performance at different temperatures is different, and the temperature difference of the battery cells of the group products will also accumulate differences during the charging and discharging process, resulting in unfavorable phenomena such as excessive final pressure difference. At the same time, the existing lithium-ion power battery packs do not have a good Heat dissipation function, so it has a certain impact on the lithium battery

Description
Technical field [0001] The invention belongs to the technical field of new energy, and particularly relates to a lithium ion power battery pack with active equalization maintenance and battery thermal equalization kinetic energy. Background technique [0002] Among all external environmental factors, temperature parameters have the greatest impact on the charging and discharging performance of lithium batteries, except that low-temperature charging and discharging may cause damage to 72v lithium batteries and high-temperature charging and discharging may cause battery aging to accelerate and affect life. When used in groups, due to battery cells The charging and discharging performance at different temperatures are different, and the battery cell temperature difference of a group of products will also accumulate differences during the charging and discharging process, resulting in undesirable phenomena such as excessive final pressure difference. At the same time, the existing lit...
