New Life for EV Batteries as Australian Company Launches New Energy Storage Unit

Australian company Relectrify is launching a 36 kW / 120 kWh commercial scale modular battery product that uses second-life electric vehicle battery packs.

EV batteries are often considered to have reached end-of-life when their batteries have degraded to 80 per cent of their initial capacity. While EV drivers may seek a new battery to improve driving range, the second-life battery remains a valuable and useful asset in stationary storage applications.

Backed by the Australian Renewable Energy Agency (ARENA) – established by the Australian Government in 2012 to improve the competitiveness of renewable energy tech – Relectrify is to roll out 20 battery units across commercial and industrial customer applications throughout Australia.

The company’s BMS (Battery Management System) + Inverter battery control technology can boost lifetime and performance of batteries, while reducing battery system costs. The technology, which was developed with support from ARENA in 2018, combines both hardware and software.

Relectrify’s project will showcase the capability of its technology to extend the lifetime of batteries while also highlighting the opportunity to reduce battery cost further using second-life batteries.

Relectrify will offer the batteries to selected Australian customers and electricity network businesses. Prospective customers include utilities, industry and communities, both grid-connected and off-grid.

“Battery storage is already playing a crucial role in supporting the transition to renewable energy within industry, however, we need to do more to make it commercially viable,” said ARENA CEO Darren Miller.

“Second-life batteries have significant potential to drive down costs, and Relectrify’s battery management and inverter technology can provide what is needed to transform them into valuable assets for businesses looking to make the switch.

“This new commercial-scale battery – roughly 10 times the size of a Tesla Powerwall 2 – will provide a cost-effective form of battery storage for use in commercial and industrial settings.”
