charging with portable generator

Fri Nov 09, 2018 12:27 pm

Hi,I'm newbie to the message board and to ev ownership.
Just bought used 2011 leaf with partially depleted battery. Does anybody know what is the amperage when charging the car with small portable generator? Is the amperage constant or fluctuating?
Trying to decide whether 1250W generator is sufficient.
Thank you for sharing your knowledge
John

While technically getting a generator with 1300W capacity for L1 charging would work, it would be stressing out the generator to work at 100% like that. I would recommend 2000w generator for L1 charging, and a 5000w generator for L2 charging. If you want to bring it with you in the Leaf, you may want to consider Propane instead of gasoline as you won't have the stench of gasoline, and the generator will last longer. I would recommend L2 charging at 240v instead of L1 charging at L1 as it will cut the charging time 3x and is more efficient as well.
Pulled the trigger on going EV on 10/2016 with a 2012 Leaf, and a Tesla Model 3 reservation expected to receive in June 2018.

Durandal!
Thank you for expert advise. I know eventually I need to replace/refurbish the battery so while waiting for the procedure price to come down few extra miles goes long way. However portable power station seems to be less messy although more expensive option. What do you think?

Why would you buy a car you need to charge with no electricity available?

I am not sure what you mean by "portable power station", but any battery-operated units will not have enough capacity to charge a LEAF. You need a 2000 watt generator to charge at 120 volts because the Nissan EVSE allows the car to draw 12 amperes which is 1440 watts. The current ramps up quickly when the car starts to charge so you need some overload capability in the generator for the initial surge.
