Just did some googling, and _including_ exit and entry through pit lanes, fastest refuel is 51.3s. I think a battery swap would be reeeeeally tough to accomplish.
And most cars refuel every 14 laps, and races are about 384 laps. Totals over 5000km in 24hrs. That's a lot of batteries...
- mdorazio 10y agoJust for comparison, your numbers come out to one refill every 52 minutes. If we assume that charging a battery takes about an hour and a half (pretty reasonable based on current charge times for an 85 kWh battery), you really only need 3 batteries total. The battery swap that Tesla originally demoed was done in 90 seconds, and that was obviously for a low-speed, consumer-friendly environment. I don't see why you couldn't do a battery swap in 60 seconds if that was an engineering priority. I still think this is a pipe dream with current battery tech for other reasons (weight, power density, overheating, etc.), but from a logistics standpoint it might actually be possible.
- ubercore 10y agoCan an 85kWh battery do 190km at race speeds? Le Mans records are 140mph (225km/h) avg speed and 253mph (407km/h) top speed. EDIT: thanks for noticing, added metric equivs. The difference was just in the sources I found reporting the units differently.
