ZEN improves domestic energy storage

The South Australian firm ZEN claims that its active balancing battery management system halves the expense of storing electricity, compared to other lithium-ion units, reports the Brisbane Times. ZEN is primarily a software company, rather than a conventional battery manufacturer, and has applied its expertise to batteries produced by its sister company, the US-based Greensmith Energy Management Systems.

The 20kWh Freedom PowerBank is the size of a large fridge and currently retails at AUD$30,000 (USD$31,000), although the company hopes this will go down to AUD$20,000 once production is ramped up. The company hopes the unit will find favour with those wanting to store low-cost, night-time electricity for use in the day, when prices can go up by a factor of five. It would also benefit those wanting to dispense entirely with their grid supplier.
