Nissan Energy

Thu Dec 20, 2018 9:48 am

Sorry if this is posted already but I didn't see it anywhere when I searched "Nissan Energy".

Nissan to create an electric vehicle ecosystem that will allow for V2H, V2B, and V2G as well as battery storage from old depleted packs. This is the first I've seen this for Nissan USA.

This would seal the deal on me buying a Gen2 or later Leaf. V2H with my solar panels and a Leaf would be a dream come true. Lets hope it gets implemented well.

So Nissan has already started this in the US? What exactly was the first step?

I'm glad Nissan is doing this but honestly, I think this is one place where I would trust an independent third party more than Nissan. At least once the battery is out of the car.

If the battery is still in the car (I guess that is what V2* means afterall.....) then yeah, go Nissan. It does raise the question of how much degradation the extra cycling would cause.

If I went down this path I think I would do it with a cheap 'worn out' battery or one from a wrecked car in which case the battery would be a stand-alone device and wouldn't need any Nissan proprietary equipment.

I think that using air-cooled packs for this is a big mistake. They will degrade from the stationary cycling in hot weather.

Extra cycling effects; minimal. Realize that V2H does not involve the abuse of power surges to over 100 KW or swings to regen to nearly -60 KW...

Its all about a smooth quiet and cool drawdown of power. Its about as night and day as you can get.

In Japan, where this is already being done, excessive degradation is being reported. I'm explaining something that is already being seen (degradation of the packs), not speculating on what might or might not happen.

Considering the background noise of "normal" degradation, I wonder how they can tell? It would be somewhat easier if people in specific regions had shared experiences but that does not seem to be the norm.

V2X concepts are certainly not new. Systems of hardware/software approved by Nissan for the Leaf that satisfies warranty conditions would be very interesting and useful - especially if affordable. I've yet to find any specific information about such US based systems that have been offered by Nissan for the Leaf - anyone??

Many (myself included) do see advantages of using EVs as energy storage devices (especially combined with home solar). Having "approved" systems for US based EVs would help bring it out of the "DIY" realm into the mainstream. The "marriage" of intermittent solar renewable energy with the (eventual) massive amounts of EV energy storage will likely be part of the answer to "cleaning up" our Nations' energy systems.

That's a fair concern. What level of increased degradation are they seeing compared to a regular pack that isn't connected to the grid?

I'm personally not in this for optimizing a TOU plan. I just want emergency backup power during outages that is quiet, clean, and seamless so I'm not as concerned about that as some of y'all might be who live in areas that have higher rates and strong TOU incentives.
