I should have asked the Nissan rep's at the ride and drive, but didn't think about it until now... But does anyone know if the Ariya will support a hilltop reserve mode (otherwise known as 'charge to 80%' (or sometimes 90% depending upon manufacturer).

For us Leaf owners, you may know that the pre-2014 Leafs supported an optional 80% charge limiter available on the charge menu, but that was removed (I don't have that option on my 2015 Leaf).

Did anyone ask about this during the Ride and Drive?

I was wondering the same thing. I wonder if Nissan recommends charging to 80% for all but long trips or if it's ok to charge to 100% all the time?

Darn I really should have asked the engineer at the Ride And Drive event. They would have had an answer. Here's the convo I just had with Airya Live Chat:

So a link to the generic spec-sheet, which doesn't mention anything about reserve/hillltop mode.

I'm assuming the answer is 'No', which is a shame because I actually do live on a hilltop and it's annoying to roll down a 700 ft elevation drop with no regen in my Leaf whenever I leave the house at 100%.

Wow! It had never crossed my mind that Nissan wouldn't include that. How can that not be EV charging 101?

The thing really should have:

• Hilltop Reserve
• Charge Start/Stop Scheduling
• Smart Phone Integration (via Wifi)
• Variable Charge Rate EVSE

On the other hand we don't know what EVSE it's going to come with either. I continue to predict/fear we get a dual voltage (120/240v) unit rated to 12 amps/2,800 (max) watts. Which means most of us are going to be buying an upgraded EVSE. If that is the case I'll be looking at something like this: Grizzl-E Smart – GRIZZL-E

More, given the low rate of the standard OBC few are going to want to run the car really low. The full 87KWH battery charge would take 12'ish hours. If we assume a recharge to 70KW (roughly 80%, and we recharge with 60 miles remaining (roughly 18 KW), then we're looking for 52KW. About 7 hours. Personally, if I don't get Hilltop I'll just manage when it starts and stops. Yes, I'm just said in day-to-day practice I'm going to be planning on 170 miles of range. That's in the area of 4 days of typical use and requires a 40 amp circuit.

Sadly, at the moment I've got a 30 amp handy, or 5.75KW. Ugh, I'll need 9 hours.

Mind you if I can keep 4 days of typical range through the winter I'll be pleased. I'll charge wifey's car on Sunday night to whatever, let's say 80%, and have her plug in on Thursday nights. If, on the other hand, I feel like 85%, even 90%, gives me what I need for 4 days in the winter then so be it.

What year is your Leaf? My 2018 and 2020 both had full regen when the charge was 100%.
I always use e-pedal; but. I don't see why that would make a difference.

Respectfully, if your 2018 and 2020 both had "full" regen when at 100% then something was very wrong with your 2018 and 2020 LEAFs.

What do you mean by "wrong"? Regen is good when the battery gauge says 100%. Remember, Nissan EVs batteries have both top and bottom "reserves" so users don't have to be concerned about the top and bottom charge status. Bolts and Teslas had to warn users they had no regen braking when the battery gauge said 100%

Moot discussion. You shouldn't be charging to 100% on the reg anyway.
