A Battery Management System (BMS) is an electronic system that manages a rechargeable battery (battery or battery), for example, by protecting the battery from operating outside its safe operating area (Safe Operating Area), tracking its status, calculating secondary data, report that data, control of your environment, authentication, and/or balancing it.1
A battery pack that features a battery management system and external data bus communication is a smart battery pack. A smart battery pack must be recharged by a smart battery charger.
