Audi is creating 72 additional charging points for electric vehicles at its Neckarsulm site through the use of so-called cubes, which use used lithium-ion batteries from dismantled Audi test vehicles to store electricity.
Two of the cubes feed a total of 48 charging points and expand the charging capacity for employees and visitors to the Neckarsulm site in multi-storey car park 1 to the south-east of the Audi plant. One Cube with a further 24 charging points is located in the car park at the north-eastern boundary of the plant. In each of the three cubes, 198 used battery modules with twelve cells each act as energy storage. According to Audi, the capacity can be expanded: there is room for 132 more modules in each of the cubes.
By supplying power to the charging points from the second-life batteries, Audi says it can dispense with the “complex installation of a cost-intensive infrastructure with medium-voltage supply lines and transformers”. All three cubes together have an energy content of 1.58 MWh, i.e. just over 500 kWh per container cube. These are each charged overnight with a 70 kW supply line at a low grid load, and during the day they deliver their electricity to the 11 kW charging points. “Thanks to the batteries in the cubes, we gain 300 kW of charging power for the wallboxes from the relatively low connected load of 70 kW,” explains Jannik Mastall, project manager
