Dear Keerthana Prithiviraj ,

it depends, strongly, on the

1) expire date, on the

2) (manufacturer's) specs, as well as on the

3) (historical) origin

of these/your Used EV (brand ?) Batteries.

One of the simplest ones is to power street lamps (that is not solar powered) in your university / nearby park. You could add few solar panels to store energy at daytime and then at night use the batteries to power up the lamps. It could be a nice project to monitor the efficiency, usage patterns etc.

Thank you for you contributions Ioannis.

I have for many years been involved in EV innovation and the Off Grid Standalone Power Plant industry as a systems designer and hard/software manufacturer, and I am experienced with re-use of EV storage stacks [up to 800 VDC] for integration with other power plant systems, including solar PV; pico-hydro; wind and ultra-capacitors.
