Battery Management System (BMS)

Products in the Battery Management PMIC (Power Management Integrated Circuit) family are used for various battery-related tasks. These include monitoring and controlling functions like authentication, cell balancing, condition monitoring, fuel gauging, source selection, short circuit protection, and over- and under-voltage protection. While some of these products may have a battery charging function, those where charging is the main feature are categorized separately.

A Battery Management System (BMS) is technology focused on overseeing a battery pack, which is a collection of battery cells arranged in a matrix (rows and columns) to provide a specific range of voltage and current for a certain amount of time based on expected load conditions.

What does a battery management system do?

The BMS's main job is to make the most of the remaining energy in a battery. It protects the battery from issues like deep discharge and over-voltage, which can happen with very fast charging or high discharge currents.

Frequently Asked Questions

Do cell phones have a battery management system?

Yes, cell phones have a Battery Management System (BMS). This system is crucial for lithium-ion batteries, as it regulates the battery's voltage and temperature to ensure it performs optimally and safely.

Why do vehicles need a battery management system?

A Battery Management System (BMS) communicates with the onboard charger to keep an eye on and control the battery pack's charging. It also helps to make the most of the vehicle's range by efficiently using the stored energy.

What does a management system do on a car?

An engine management system in a car includes a range of electrical and electronic components like sensors, relays, actuators, and an engine control unit (ECU). These components work together to provide the system with important data needed to manage various engine functions.
