Get the right charge, you're halfway there

The charging system of the Volkswagen ID.R

It is a science in itself: the ID.R charging system. Only with optimally charged batteries can the pursuit of the lap record for electric vehicles on the 20.8-kilometre Nürburgring-Nordschleife succeed. To this end, driver Romain Dumas (F) will also have to deploy the full system performance of 500 kW (680 PS) on the three-kilometre ‘Döttinger Höhe’ section at the end of the Nordschleife, which is nearly dead straight.

“To drive a whole lap of the Nordschleife with full performance is a huge challenge for electric drive,” says François-Xavier Demaison, Technical Director of Volkswagen Motorsport. “Therefore, optimal charging before the lap begins, along with the recuperation when driving, are of crucial importance.” Marc-Christian Bertram, Head of Electrics and Electronics at Volkswagen Motorsport, continues: “The ID.R’s battery has a particularly high power density. It is not maximum range that is required, but rather the highest possible power output. That is why we chose a lithium-ion battery consisting of eight modules with 56 cells each, divided into two blocks next to the driver and behind the monocoque.”
