Microgrid Energy Storage Units

Used vehicle batteries for microgrid storage
NOVEMBER 17, 2012 - Clean Technica reported on Nov. 16, 2012 that GM and A.B.B. had made a conversion of Chevy volt batteries into usage by microgrid energy storage units for an alternative energy resource.

The one thing that makes this variant different from current microgrid storage battery systems is the fact it utilizes batteries from electrical vehicles.

The system contains 5 used Volt batteries which can provide 25 kW of energy for two hours bringing the total to a 50 kWh energy capacity. Doing the math, at this rate, this can provide power to three to five homes for a period of two hours.

That being said, such a battery holds around 16kWh when first installed in a vehicle As time passes, it looses it's ability to keep a charge, but with this latest development, this could mean that there could be an extension of battery life. read more>>>
