How Lithium-ion Battery Management Systems Enhance Battery
It''s crucial to maintain an even charge across all of the cells in a lithium-ion battery pack because they are made up of numerous individual cells. The BMS does this via active or passive
At the heart of any solar storage system, you'll find a Battery Management System (BMS). This vital component is responsible for the efficient operation of your solar energy storage, guaranteeing peak performance and safety. The primary role of a BMS for solar is managing the charge and discharge of the solar battery bank.
The BMS helps batteries last longer too. It balances cells so weaker ones don't limit the pack's performance or get damaged faster. By stopping deep discharge and overcharge, it protects against common causes of permanent capacity loss. Lithium-ion batteries need precise control.
With residential ESS systems (especially with Lithium Iron Phosphate batteries), it's often unnecessary to have active balancing; passive balancing is most often used. Passive balancing, or top balancing, essentially uses the principle of discharging the cells through a bypass route as each cell reaches a defined top voltage.
This essential data informs the BMS when to stop charging or discharging to prevent battery damage or degradation, hence prolonging the life of your solar battery. Moreover, a BMS for solar is a safety net. It automatically cuts off power in cases of overcharging, overheating, or short circuit.
