There are two ways to match in battery packs: more common electricity conditionsThe state (SOC, the percentage of battery capacity) does not match and does not match the capacity/energy (C/E). Both will make the capacity of the battery pack (MA · H) restricted by the weakest battery core. In the case of battery series or parallel connection, the pre -level analog end (AFE) can eliminate the non -matching between batteries and greatly increase the battery efficiency and overall capacity. The possibility of not matching batteries increases with the number of battery cores and the increase of load current.

　　When the pool core in the battery pack meets the following two conditions, we call a balanced battery:

　　If all battery cores have the same capacity, when they have the same relative power status (SOC), the title is balanced. Opening circuit voltage (OCV) is a good SOC indicator under this condition. If all the battery cores in an unbalanced battery package are charged to the complete charging state (at this time it is balanced), the next charging circulation will return to normal without additional adjustment.

　　If there is a different capacity between the battery core, we still call the state of all battery cores in the same SOC state. Since the SOC is a relative measurement value (the residual discharge percentage of the pool core), the remaining absolute capacity of each battery core is different. In order to keep the battery core of the battery core of the battery core of the battery core, the battery core is the same. SOC, the balancer must provide different currents between different battery cores connected
