Systems integrator Powin Energy could gain an award today for a seemingly bizarre energy storage application: using batteries to charge batteries.

The Oregon, USA-based company is among those shortlisted for a 2016 Energy Storage North America Innovation Award for an electric vehicle fast-charging station at the headquarters of microprocessor firm Intel.

The installation, in Santa Clara, California, uses Powin Energy’s Battery Pack Operating System (bp-OS) to manage 30kw and 43kWh of lithium iron phosphate storage linked to 15 SolarWorld PV panels with a capacity of 4.1kW.

The use of batteries for electric vehicle fast charging avoids the need for standard three-phase 208/277/480V AC connections and helps avoid high demand charges, said EV4, the firm that designed and manages the station.

The technology also makes it possible to place charging stations in areas where three-phase AC is hard or costly to obtain.
