WMG researchers convert used EV batteries into small off-grid ESS units

Green Car Congress

Researchers at WMG, University of Warwick, have repurposed end-of-life electric vehicle batteries as small energy storage systems (ESS) for off-grid locations in developing countries or isolated communities. Multiple 12V DC sockets and 5V USB charge ports. Enough energy for a small shop, farm holding or multiple residential homes.

SwRI develops device to test friction, wear associated with EV fluids

Green Car Congress

This small-scale bench test was built around a traditional universal testing machine. An inverter takes the direct current (DC) voltage input from the batteries and converts it to the AC power required to operate the vehicle’s motor. The setup and test protocol were further developed by the team throughout the project.
