Four minutes and 37 seconds. That’s how much time it took for Nyobolt’s working EV prototype to top up its batteries from 10% to 80% charge using a 350-kilowatt DC fast charger. That’s roughly the same time it takes to fill up an internal combustion car’s empty gas tank—a large one, at least–making it pretty clear that EV tech is on the right track to dethrone ICE vehicles in the near future. However, there are some asterisks.
Furthermore, the Cambridge start-up claims that its 24.5-amp-hour cells have successfully gone through over 4,000 full Depth of Discharge cycles, which equate to over 600,000 miles in the case of the lightweight two-door Nyobolt EV prototype. The lab testing also concluded that the cells retained over 80% of their capacity after these fast-charging cycles, an impressive feat on its own.
