Volkswagen I.D. R Pikes Peak Pure Electric Car Can Be Fully Charged In 20 Minutes

- Sep 27, 2019-

According to foreign media reports, the Volkswagen team has improved its charging technology to ensure that the IDRPikesPeak pure electric car has enough power in the 24th of this month to use the two 90kW charging devices. Charging, so that the car can be fully charged in 20 minutes, return to the track.

Due to the rules of the competition, the car is only charged for 20 minutes at the interval. Therefore, while meeting safety requirements, the car should increase its charging efficiency as much as possible. To this end, the Volkswagen team equipped its pure electric racing car I.D.RPikesPeak with two 90kW charging devices and simultaneously charged the power battery, which greatly improved the charging efficiency of the power battery. Since the two devices are divided into two groups of circuits to simultaneously charge the power battery, and the power battery is also divided into two groups, the total charging power is shared, so that the heat generation of the battery is greatly reduced, and the influence of high-power charging on the performance of the battery is reduced. And improve the safety during the charging process.

Despite this, Volkswagen I.D.RPikesPeak pure electric racing car still designed the air-cooled power battery temperature control system to maintain the optimal charging temperature of 30 degrees Celsius. However, it is not possible to provide cold air inside the battery pack during heat dissipation, as this may cause condensation to form, causing problems in the electrical system.

It is understood that there is no power supply for the charging equipment at the venue, so the Volkswagen team relies on traditional generators to provide power. It is worth mentioning that the team does not use traditional fuel like diesel, but uses glycerin. Glycerin is a more environmentally friendly by-product of biodiesel that does not produce harmful gases or residues when burned. Glycerin itself is also a non-toxic liquid and is even allowed to be used as an additive in the food and cosmetic industries.
