A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), calculating secondary data, reporting that data, controlling its environment, authenticating. FunctionsA BMS may monitor the state of the battery as represented by various items, such as: • : total voltage, voltages of individual cells, or voltage of periodic taps • : average temperature, coolant intake temp. .
BMS technology varies in complexity and performance: • Simple passive regulators achieve balancing across batteries or cells by bypassing the charging current when the cell's voltag. .
