A battery management system for dynamically balancing power in a battery module is provided. The battery management system comprises a plurality of modules, and each of the plurality of modules comprises a plurality of bricks. Each of the plurality of bricks comprises a plurality of blocks, electrically connected in one of a series configuration or a parallel configuration and a controller assembly provided in each of the plurality of the modules. The controller assembly comprises a first converter adapted to be connected to the plurality of bricks and a second converter adapted to be connected to an external system. The controller assembly is configured to obtain a plurality of battery pack parameters from the plurality of bricks using the first converter, process the obtained plurality of battery pack parameters and determine a current level to regulate a charging or discharging of the battery pack using the second converter.

System and method for dynamically balancing power from distributed power sources in a battery pack

A system for dynamically balancing power in a battery pack during charging and discharging includes a battery pack, a control unit, and a load unit. The battery pack includes one or more modules. Each module includes one or more bricks. Each brick includes one or more blocks connected either in a series configuration or in a parallel configuration. Each block includes one or more cells. The control unit is connected with the battery pack across each of the blocks for processing power from each of the blocks irrespective of a power mismatch between the blocks. The control unit dynamically balances the power in the battery pack by controlling a differential current from a block with higher state of charge (SOC) to a block of lower SOC, using one or more converters and thereby maximizing available energy of the battery pack during charging and discharging.
