Volkswagen Presents Charging Of The I.D. R: Video

Volkswagen I.D. R – electric power pack on four wheels – currently the fastest electric race car in existence.

Volkswagen is gearing up its all-electric racing car I.D. R for the record attempt at the Nürburgring Nordschleife later this year.

The German manufacturer recently shared a video about how challenging it is to perform a 20.8-km run at full power of up to 500 kW, including the three-kilometer nearly dead straight ‘Döttinger Höhe’ section.

The I.D. R is not equipped with liquid cooling to save weight, so it must be cooled via cool air during the charging sessions. The DC fast charging is done at up to 90 kW – not that much as the team doesn’t want to increase the battery cell temperature.

“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.”

François- Xavier Demaison, Technical Director of Volkswagen Motorsport said:

“To drive a whole lap of the Nordschleife with full performance is a huge challenge for electric drive. 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.”
