What Is A Battery Management System?

A battery management system is a piece of equipment that will read data in a system and act on it, in a way that it will change certain parameters to protect the equipment in the system.

Batteries are important pieces of equipment for different practical applications. In some cases, like emergency power backup systems, a battery failure can be critical and create a crisis situation. To avoid such situations, it is wise to make use of a battery management system. A well-rounded understanding of this topic can be developed by understanding its basic definition, capabilities, and applications.

A battery management system, in very basic terms, takes care of a battery or a pack of batteries by protecting the battery health. The functionality of a battery management system involves various activities. Some of them include monitoring, reporting, controlling, and protecting. To give an overview of the process flow, the system would monitor and report readings such as voltage, current and temperature.

These readings would be used for calculations such as the charge level of the battery and the total number of cycles. The processed information is also used to assist the protection mechanisms of the system which protects the battery from threats like over-voltage and over current.

The purpose of having a battery management system in place is to ensure its normal operation for the longest possible duration. This opens the door for the application of battery management systems in a broad range of sectors.
