Battery Management System

A battery management system or Battery Management system (BMS) is a technology system that functions to maximize the life of an electric vehicle battery and its characteristics. It is strongly recommended that all battery-powered electric vehicles be installed with BMS. The aim is to ensure the battery stays within the ideal working parameters. Some battery chemicals (such as lead acid) are tolerant of misuse. Still, lithium and NiMH can both be permanently damaged by abuse such as overcharging, over-discharging or overheating.

All types of electric car batteries will benefit significantly by installing a BMS.

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 balancing it. A battery pack built together with a battery management system with an external communication data bus is a smart battery pack. A smart battery charger must charge an intelligent battery pack.
