Nano batteries need BMS

What is a battery management system (BMS)?

The BMS protects the battery from damage, extends the life of the battery with intelligent charging and discharging algorithms, predicts how much battery life is left, and maintains the battery in an operational condition. Lithium-ion battery cells present significant challenges, demanding a sophisticated electronic control system.

Why should you use a BMS for a lithium-ion battery?

A properly designed BMS for lithium-ion batteries is not optional—it's essential for safe, reliable, and efficient operation. The technology protects valuable battery assets, ensures user safety, and maximizes performance throughout the battery's operational life.

What happens if you run a lithium battery without a BMS?

Operating a lithium battery without a BMS can expose it to risks that might compromise safety and efficiency: Overcharging and Deep Discharging: Without a BMS, cells in a battery can exceed their voltage thresholds during charging or can be depleted beyond safe levels, both of which can lead to battery damage or failure.

How accurate is a battery management system (BMS)?

The BMS employs multiple algorithms including coulomb counting, voltage-based estimation, and advanced techniques like Kalman filtering to provide precise charge level information. SOC accuracy directly impacts user experience and battery protection. Overestimation can lead to over-discharge, while underestimation reduces usable capacity.
