In fact, if I was receiving a jump-start in the Leaf (from a tow truck or ICE car), I would ensure that the donor car is OFF to keep the power rails quiet. Automotive electricity is a nasty place.
The LEAF does not have or need a starter motor/alternator. When a 12v dies it's usually dead so the LEAFs 12v system is off until it's replaced... or is it? Does raise a question of what does the LEAF do when it's 12v system fails. Will its 12v functions run off of the propulsion battery and tell you to replace the 12v??? I think it's going to be a bit of an adjustment for everyone regarding the simple anatomy of Electric Cars. The people with Owners Manuels might be able to verify more on this and if jump starting is recommended for gas cars.
Agreed. Since the leaf doesn't have a starter or motor, the 12v is likely too weak to safely start anything but a smaller vehicle. It's all about the amps, and the LEAF's 12v will be fairly week, I think.
In regards to what happens when the LEAF is dead, my guess is that electric cars, when dead, will have to be towed home OR be recharged from a significant battery bank on a tow truck to get have enough power to get home. This is assuming the car has been driven to its range-limit, or 100% depth of discharge, at which point the car will shut down to protect the batteries.
I have no idea what will happen when the 12v dies, but a good guess would be that you simply replace the battery and the car's auxiliary systems will come back to life. If you're talking about reacharging the 12v, its probably safest to disconnect the terminals and charge the 12v without its connections to the car.
Just guessing...
