Batteries,BMS & Charger
A battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and/or balancing it.
