These are the battery chargers are mainly used for charging
the battery bank which is responsible for control supply of
control systems such as breaker closing coil, trip coil,
protection relays etc.
**In float charging battery is charged with the same rate
as it is discharged.It is used when battery rarely gets
discharged.It requires charging the battery at reduced
voltage to avoid the battery from overcharging.

**Boost charging involves a high current for a short period
of time to charge the battery. It is used when battery is
discharged heavily, it enables quick charging of batteries.
