As batteries can store a huge amount of energy, so sudden discharge or fault can result in catastrophic failures. By handling and maintaining the battery’s functional factors, and protective mechanisms, avert these unsafe operations and prevent dangers such as overcharging, overheating, and short circuits.
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
The most common methods of implementing backfeed protection in UPS systems include the use of transfer switches, static transfer switches (STS), and intelligent circuit breakers. These devices ensure a safe and controlled power transfer between the UPS system and the utility grid.
