Audi is funding a project by the start-up Nunam. Batteries from E-Tron test cars donate electricity to businesses in India, which improves working conditions and in some cases makes it possible to earn money locally.
The batteries are among the most expensive components of an electric car, and valuable raw materials are also used for the batteries. After the end of a car’s life, electricity storage systems are far from being recycled. Depending on their condition, they can be reused in different ways, for example in stationary systems.
The start-up Nunam takes care of the second life of batteries. Audi is now the new cooperation partner of the Berlin company. The lithium-ion batteries from two discarded E-Tron test vehicles were assembled by Nunam to form a solar nano grid. A photovoltaic system generates electricity from solar energy, which is stored in the batteries.
Batteries help with power outages
The prototype that Nunam built with the two batteries from the electric cars is in use in India. There it supplies enough electricity to enable 50 dealers and self-employed people to work even after dark.
“In parts of Uttar Pradesh, hours of power outages regularly make life difficult for local residents,” explains Nunam, Prodip Chatterjee, co-founder of Nunam. A lack of electricity means a loss of income for many people in the affected areas. The start-up wants to help out with its battery storage systems.
In a first step, batteries from old laptops were used, with which low-power consumers such as lamps or smartphones can be charged. With the larger batteries from the Audi E-Tron, enough energy should also be made available for larger consumers and for a higher number of customers. Audi supports the work of the non-profit GmbH and is now also providing the E-Tron batteries.

The prototype of the solar nano-grid should be able to supply 50 small shops with electricity for the LED lighting of the shops for a week on a full charge.
