In between the final Formula E test sessions at Donington Park, Qualcomm unveiled the BMW i8 safety car. However it was hard to spot any differences to last season’s version, there was a large upgrade to report.
Instead of a 3.6kW wireless charging system, the Qualcomm BMW i8 Formula E safety car has now been equipped with a Qualcomm Halo 7.2kW system. It indeed delivers twice the amount of energy to the battery per hour and approximately halves the full charge time, enabling the vehicle to fully charge in one hour.
Employing Qualcomm Halo DD technology, with magnetic architecture optimisation, ensures higher coupling coefficients and drives lower system currents, higher efficiencies and the ability to support higher power levels.
“We are excited to continue our support of Formula E in this second season,” said Steve Pazol, general manager of wireless charging, Qualcomm Incorporated. “Qualcomm is showcasing its innovative new technologies within the championship and using the motorsport platform to accelerate the development of automotive technologies, which is perfectly illustrated by the wireless charging technology fitted to the new BMW i8 Safety Car.”
However recorded during last year’s launch, this video gives you an idea how Qualcomm’s wireless charging system works:
So far BMW isn’t interested in the all-electric racing series as long as drivers have to switch cars mid-race.
