It's gonna take some power to be able to get back home too!  |
We're not talking about an "EV RV" we're simply talking about using a Li-ion battery pack instead of the house batteries. The propulsion would still be gas or Diesel. The term "electric coach" is being used now to describe coaches that use an induction stove with a residential fridge and an electric water heater (no propane).
However, since you're asking about charge times:
- The 7.7kWh battery in my C-Max takes about 2 hours to charge up from empty using 240V @ 35Amps
- The 23kWh battery my old Focus Electric had took about 3.5 hours to charge up from empty using the same 240V @ 35Amps
If you have a 5kW generator you could charge up 7.5kWh battery pack in about 1.75 hours (there is some loss in there). Likewise the same 5kW generator could charge a 25kWh battery in a bit more than 6 hours (again the charging process is not 100% efficient--its more like 80%-90% efficient).
