Technical FAQs 4

Why do lithium batteries need a BMS?

The BMS prevents your lithium battery’s voltage from going too high (causing overheating and gas release) or too low (leading to permanent damage). Damage occurs if you overcharge (cell voltage gets too high) or over-discharge (cell voltage gets too low) a lithium-ion battery cell. Overcharging occurs when recharging exceeds a battery’s safe range.

Why should you use a battery management system (BMS)?

By balancing cells, controlling charging and discharging, and implementing safety measures, the BMS ensures your EV battery stays in top condition. For the driver, this means more reliability, better performance, and fewer worries about battery health.

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.

Do I need a battery management system?

For most RV, marine, and off-grid applications, an internal BMS is the safest and most convenient choice. Our team does not recommend purchasing a battery unless it has an internal battery management system. If you’re running lithium batteries, a BMS isn’t optional — it’s essential.
