In terms of maintaining an EV, there is very little required, and even less that you can do yourself. No oil change, no timing belt, no gasket seal that can break.
As part of the regular service carried out by the main dealer (around €120), the cabin pollen filter gets changed, and that's about it. Obviously, if wear and tear items such as wipers and brake pads need to be replaced, then that has to be done too, just like with any car. The service carried out by the main dealer is required mostly to get the service book stamped, as the warranty depends on a full history. The warranty with the version of LEAF I have is 3-years bumper-to-bumper and 5 years on the batteries and motor. My car won't be 5 years old until 2020, so I will get the service from the main dealer as necessary to keep the warranty in place.
But apart from that, the car is pretty much maintenance free. Top up the brake fluid if necessary (it hasn't been necessary on my car so far), and keep the windscreen washer tank filled, and away you go.
