Description

technical field [0001] The invention relates to the field of batteries, in particular to a system for realizing balanced charging of batteries. Background technique [0002] Equalizing charging refers to charging that equalizes battery characteristics. During the use of the battery pack, due to the individual differences of the batteries, temperature differences and other reasons, the battery terminal voltage is unbalanced. In order to reduce the trend of unbalanced voltages at the battery terminals, it is necessary to balance the battery characteristics in the battery pack and prolong the battery life through the maintenance method of balanced charging. [0003] When charging the battery pack, the state of charge (SOC) is calculated according to the highest cell voltage; when the battery pack is discharging, the SOC is calculated according to the lowest cell voltage. Usually, a battery pack is composed of multiple cells connected in series. In the charging state of the ba...
