The reason why electric cars aren™t everywhere is simple ” at the end of their range, they have to be stationary for hours while the batteries are recharged.

This is a pity, because even cars recharged from Ëœdirtyâ„¢ power stations are three times more environmentally friendly than conventional vehicles. Thatâ„¢s because only 20 per cent of the energy from gasoline or diesel actually reaches the wheels; in an electric car, itâ„¢s 60 per cent.

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.The

The typical future-tech scenario calls for millions of low-powered radio frequency devices scattered throughout our environment -- from factory-floor sensor arrays to medical implants to smart devices for battlefields.



Because of the short and unpredictable lifespans of chemical batteries, however, regular replacements would be required to keep these devices humming. Fuel cells and solar cells require little maintenance, but the former are too expensive for such modest, low-power applications, and the latter need plenty of sun.

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
