Introduction
The objective of this activity is to use EV batteries in a sustainable way by giving them a second life. Reusing old batteries will considerably benefit the environment as less resources will be used to produce new batteries and energy storages and at the same time, renewable solar energy will be used to charge the EVs. The system will thus consist of old EV batteries, PV panels, EV chargers and battery charging equipment. The latter is the most important part of the system as this equipment is currently not available on the market.

The planned system allows to fully charge in a sustainable way around 30 EVs each day, depending on the location of the system. Also, depending on the climate conditions, surplus electricity produced by the PV panels can be used for other on-site purposes (e.g. lighting) or sold to the grid.
