What are BMS batteries used for?

BMS batteries are used in virtually every industry where lithium-ion batteries are found, including: Electric Vehicles (EVs) Ensures battery safety, efficiency, and extended driving range. Energy Storage Systems (ESS) Balances large-scale battery packs for home and commercial solar power systems.

What is battery management system (BMS)?

Battery Management System (BMS) is the “intelligent manager” of modern battery packs, widely used in fields such as electric vehicles, energy storage stations, and consumer electronics.

Why do EV batteries need a BMS?

A battery (lithium ion battery) used in an EV deteriorates every time the battery discharges or is charged. These cycles of battery deterioration may lead to a drop in the vehicle performance. The BMS is an important solution to this problem.

Do lithium batteries need a BMS?

However, they also come with strict requirements for safe operation. Without a BMS, a lithium battery is vulnerable to: A well-designed BMS prevents these issues by acting as the “brain” of the battery, constantly monitoring its state and taking protective actions when needed.

Does a battery pack need a BMS?

In a battery pack with multiple cells, a single BMS typically manages the entire pack, not individual cells. However, if you have multiple independent battery packs, each pack requires its own BMS to monitor and protect its cells.

Why do multi-cell batteries need a BMS?

Cell Balancing Especially in multi-cell packs, small differences in cell voltages can lead to imbalance over time. The BMS actively balances the cells during charging to maintain uniform performance and prolong the battery’s life.
