Traditional auto batteries carry a 8 year/100,000 mile (160,000 km) warranty, but generally outlasting its known lifespan, according to Oilprice.com

A consortium led by automobile manufacturer Mercedes-Benz will set up a grid storage facility in Germany that will utilise used automotive batteries for home and industrial energy storage applications.

According to Oilprice.com, the project is aimed at “driving more interest in grid-scale utility storage and help to blend the consumer and commercial markets for batteries.”

The project is based on the premise that when EV and plug-in vehicle batteries reach the end of their working life for automotive applications (no longer reliable to start a car), the battery still has up to 80% of its original storage capacity remaining.

The project is expected to be the “world’s largest grid storage facility using used batteries,” and will have the capacity to store 13MW of power, which will be enough to provide electricity to 130, 000 homes.

The batteries will also be connected to incorporate wind and solar power.

Second life for EV batteries

The project is also intended to give used batteries a ‘second life’ with use in energy storage applications, as opposed to being discarded.

The big advantage is the economic value of using recycled EV batteries for projects like the one in Germany.

There is also the possibility of used batteries to lower the effective cost of electric vehicles for consumers, and make them more attractive to consumers.

Re-using EV batteries has the potential to “improve the economics of EVs – a possibility which has previously been absent,” says Oilprice.com

Mercedes Benz’ utility scale grid storage system is said to demonstrate their “out-of-the-box” take on storage applications in an attempt to meet the need for household energy use.

In addition, used batteries are poised to accommodate an increasing amount of clean energy comes online, with the recycling of batteries expected to become a “multibillion dollar business.”
