Rimac Upgrades Fan’s Electric Wheelchair


Powered by a 91 kWh lithium-ion phosphate battery pack and four-electric motors making a total of 1,088 horsepower, the Rimac Automobilii Concept_One is a mighty electric supercar. Electric supercar builder Rimac has showcased another use for its EV technology; improving the performance of a fan’s wheelchair.

Rolly Bugnar contacted Rimac to see if the company could help improve the performance of his underpowered wheelchair, and Rimac responded in the best way possible. While their ultimate goal is to sell EV powertrain parts to niche automakers, Rimac engineers repurposed the battery system from another one of their products, the Greyp electric bicycle, along with the battery management and human interface modules for Frolly’s wheelchair.

As a result, Rolly’s wheelchair has six-times more range now than it used to, up from just six miles to an impressive 37 miles between chaires. The lithium-ion batteries more than 20 pounds lighter than the lead-acid batteries that used to power his wheelchair, which means it goes a little bit faster too.

The system is one-off, and for now Rimac has no plans of replicating it. But it just goes to show that the advantages of the EV spread far beyond the confines of the auto industry.
