Apparatus for a modular battery management system (100) with interchangeable slave modules (112) connected to each cell (108) and including a master module (110) controlling and managing the battery system. All the modules (110, 112) receive power through a transfer switch (104) that selectively switches between an external source (102-A), an auxiliary source (102-B) and the battery (106). The modules (110, 112) are configured to connect to a cell (108) of the battery (108) for charging and monitoring the cell (108) individually. Each module (110, 112) is electrically isolated from the other modules. The modules (110, 112) are autonomous and shut down the battery (106) and disconnect the module (110, 112) when a critical parameter of the cell (108) is reached. When the battery (106) is in service and a cell parameter approaches the critical level, the master controller (110) instructs the corresponding slave module (112) to charge the cell (108) using battery power. The master module (110) initializes the slave modules (112) to uniquely identify the modules (112). |
