An aftermarket kit to improve charging to 6.6kW

Sat Jul 28, 2012 9:10 pm

What needs to be added or replaced to increase charging from 3.3k to 6.6k level 2? I would pay for this upgrade

The charger, which is located inside the Leaf. At one point, Nissan hinted that they might be able to upgrade current Leafs, but now they say it can't be done. Forget it, not gonna happen.

Now that makes me really feel like a 1st gen real EV car guinea pig. I'm holding out hope that Nissan will be kind to us 2011, 2012-ers and actually do something about it and offer an expensive but possible fix. Let's face it, the car is a one trick pony.

Honda where are you? Prelude EV please!

Nissan will never offer a retrofit; too complex/too expensive. You'd really need to wait for a small 3rd party to do it. And it will never be "cheap." I personally have no interest in paying for an upgrade, simply because I rarely use public L2 charging... and when I do, making it a little less than twice as fast doesn't help my use scenarios much. Quick/Fast Charging, however, I've found far more useful.

Prelude EV? Oh come on... ;)

I thought someone posted the charger (3.3kW) alone was about $2500. Add in the harness and new software you should quickly approach $5,000 or more.

Trading for a 2013 with the 6.6 would be less money.

I was wrong, the current 3.3 assembly is only $1500. Still a 6.6 would surely be higher.

I would rather have something that can use the L3 port on mine (that has never been used). Maybe an L2 to L3 external adaptor?

More specifically, the charger is located in the hump behind the back seat. A higher capacity charger will almost certainly be physically larger. Can it be configured to fit inside that hump? Maybe, maybe not. Rumor has it that Nissan isn't even going to try, and will relocate the larger charger to the front of the car. Can you imagine trying to reconfigure the "engine" compartment of an existing car to accommodate an additional component like that?

Not to mention that the charger is water cooled and uses some very hefty electric cables. The larger charger will need more cooling. Is the existing system adequate for that? Probably, but who knows. It will definitely need larger cables running back to it from the charge port at the very front of the car. Not only are these expensive, but will there be room in the existing channels for the larger diameter wires?

Of course it's doable, at a price. How many thousands of dollars are you willing to spend, and how many others can you find willing to spend those amounts so that there is a viable business plan for the product?

That wouldn't be an "adapter", but an external charger. The Quick Charge port doesn't connect to the charger. It bypasses that and connects directly to the battery. Since you have never used QC you may not have seen the refrigerator-size charger boxes that hum away off to the side of the user-interface charging unit. Of course that is the size you need for 50 kW charging; the 6.6 kW charge rate you are thinking of could be done with a much smaller charger box, but it would still be heavy and bulky. Are you imagining carrying it around with you all the time in the back of the car? Wild guess: By the time you include self-contained cooling, it might fill most of the recessed part of the hatch storage space, and weigh up to 100 pounds.
