FAQ
Q: What does a smart BMS do?
A: Temperature impacts, lifetime aging, self-charge/discharge, and other variables are all within the control of the smart BMS. The usage of BMS is pointless without any of this. Therefore, BMS applications guarantee that your battery is constantly operating at its best capacity and range.

Q: What is the difference between smart BMS and BMS?
A: Features of smart active balance BMS: Smart active balance BMS performs better in terms of protection than standard BMS. By automatically regulating the battery pack’s voltage and current, it can provide more accurate protection.

Q: What are the three types of BMS?
A: In total, there are three common types of BMS architectures:
Small, single-board BMS
Distributed BMS
Large, centralized BMS

Q: What is the difference between smart BMS and dumb BMS?
A: The main objective of dumb BMS is simple voltage and current monitoring. It ensures battery safety by providing protection against overcharging and overdischarging, but it lacks the sophisticated capabilities of a Smart BMS.

Q: What does a smart management module do?
A: By managing power consumption and preventing overload, Generac’s Smart Management Modules (SMMs) enable PWRcellTM to maximize its leading backup power and capacity.

Q: Why do I need a BMS?
A: A BMS keeps an eye on the operating conditions and takes action to prevent dangerous situations by altering the charge/discharge rates or switching off the battery.
