It's been done several times, as in the example by jray3.
All you need to do is connect to the main bus. That's the main two power wires coming out of the traction battery. One is positive and the other negative. Just hook up to those. As long as you don't put any voltage to them when the car tells the main contactors to open you'll be fine. Basically you need another set of contactors to close and open synchronously with the main contactors or turn them on after turning on the car and turn them off before turning on the car.
With your extra battery or APU (auxiliary power unit) generator supplying electricity to the main bus the Leaf won't be able to tell where that extra power is coming from. It's like hooking up a second 12V battery or a second alternator to a car battery. How's the car going to know where the electricity is coming from? It's not. The car will continue to function normally by drawing electricity from off the main bus. The difference is that you're feeding electricity into the main bus by two different means, the Leaf's own traction battery and your auxiliary battery or APU generator or solar roof or hydrogen fuel cell or portable nuclear power generator or whatever.
This guy shows where to hookup another power source. He also makes the mistake of having that power source hooked up while the battery is trying to disconnect from the bus.
