BATTERY CHARGERS & BATTERY BANKS
INTRODUCTION
NEED OF BATTERY CHARGERS & BATTERY BANKS
Station battery charger is used to supply the control power to the electrical switchgear like breakers etc which need the DC supply for it’s operation and in case of failure of electrical power the control power is continued to be fed by the battery.
Battery Charger consists of
1) Float Charger
2) Boost Charger
Schemes for Battery Chargers
1) FC & FCBC scheme
2) FCBC & FCBC scheme
SINGLE LINE ....etc

The VRB-ESS is a device that is capable of storing energy in multi megawatt ranges for durations that range from hours to days, from any available input source such as Grid, Renewable resources or even from a diesel generator. The stored energy can then be provided back into the Grid or supplied to a load as required & directed. It is uniquely capable of being charged as quickly as it was discharged. This seminar presents the various features & applications of the VRB and discusses its future in the coming years.
