1000KWh Battery Energy Storage System For Large-Scale Energy Storage

Grid-connected battery arrays are viable backup and carry-through power sources; application-specific measurement ICs which meet their unique and sophisticated requirements ensure reliable system performance.

The use of large-scale battery arrays for backup and carry-through energy storage is getting increasing attention, as evidenced by Tesla Motors' recent announcement of their Powerwall system for homes and offices. The batteries in these systems are continually charged from the power-line grid or other source, and then deliver AC-line power back to the user via a DC/AC inverter.

Using batteries for power backup is not new, with many systems spanning basic 120/240Vac and several hundred watts for short-term desktop-PC backup, to thousands of watts for specialty vehicles, such as ships, hybrid cars, or all-electric vehicles, up to hundreds of kilowatts for grid-scale telecom and data-center backup. Yet while advances in battery chemistry and technology get much of the attention, an equally critical part of a viable battery-based installation is its battery management system (BMS).

FAQ

Q: What affects battery lifetime?
A: The battery life is mainly determined by the use cycles of the battery. An AGM or flooded battery may have a life of 300 to 700 cycles under normal use; however that of a gel battery may be from 500 to 5000 cycles. The battery completes a cycle when it is charged and discharges once.

Q: How long will a 10kW battery power my house?
A: Residential. In case of power outages, the 10kwh Battery Pack can power your home for about 8 hours on average 1kWh / hr for 8 hrs Combine the 10kWh Battery Pack with solar or use independently to provide your home with power both day & night.

Q: How big of a battery would you need to power a house?
A: A 400 amp-hour 6 volt battery can provide around 2.4 kilowatt hours of power. A three-day battery bank planned to provide 90 kilowatt-hours of electricity to an average American household. The previous example battery can provide2,4 kilowatt hours, while 38 batteries would be needed.
