A diesel generator set that can output 100kW continuously for fast charging starts at around 2000kg / 5000lbs. You can fit a lot of battery capacity for a lot less weight that that!
- masklinn 8y agoYou really can't. The 85kWh Model S battery pack is more than 500kg.
- Reason077 8y agoAn 85kWh pack can easily sustain, say, a 100kW discharge rate. You could even double that and still be half the weight of the generator set [^]. A 10 minute charge and you'd have topped up the stranded vehicle with 16kWh, enough for 50 miles or so travel to get home or to the nearest fast charger. And you'd still have plenty left in the pack in the unlikely event of further callouts. [^] (Modern EV packs already have significantly higher energy density than the old 85kWh Model S, by the way).
