I've never seen "<1%" on my 2018. It is either 1% or 0%.
That's a new one. Is the sequence...2%...1%...<1% or ...2%...<1%? Frankly, I'd be happier with a simple declination of...2%...1%...0%.

I wonder if it has to do with how long it takes for it to switch over to ICE operation. It doesn't seem to be an immediate switch over upon hitting 0%.

Recently, I had gotten down to 0%. However, I was near a charging station and it 'seemed' like it stayed on battery, for maybe as much as a half mile (or more).

So, the question is, how long does a PacHy actually remain on battery power, even if it indicates 0% (or <1% on a 2019)?

I suppose it's some sort of legal/engineering thing. Removing every last bit of charge from a battery is not good and holds the potential of shortening its life (if not outright bricking it). So, maybe in an effort to make it more accurate to say a tiny bit of charge is retained, they went with "<1%" instead of "0%" the latter of which, technically, looks like the battery is completely discharged (when it really isn't).

2%..1%..<1%

Also, they don't completely drain the battery ever so that they won't brick it and can offer the long warranties that everyone wants because they're scared of battery replacement costs.

Looks like another difference between 2018 and 2019 PacHy has been discovered.

I wonder if there's any actual difference between '0%' and '<1%' or if it's just some engineer's idea of being more technically correct in the readout since the battery is never really down to a completely discharged state of '0%'.

It sounds rather like the readout on the Prius which, although it would show between "100%" or "0%", in actuality, a Prius' battery is only charged to 80%, and is never discharged less than 60%.

Yes I noticed this - our work fleet '17 Pachy went to 0% but my personal '19 Pachy does the <1% thing. I figured it was just noting the same thing. Like mentioned above, 0% isn't accurate as there is always some minimal charge being held.

Didn't know that a Prius only does 60%-80% of use - why is that? I understand peak performance ranges on a battery but why limit use like that

From what I’ve heard it is harder on lithium-ion batteries when you charge/discharge them when they are near the fully charged or fully discharged state. It’s much better to keep them in a range of, say, 20%-80%. I’m sure that most devices like cell phones do a similar thing. Their indications of 0% and 100% are not necessarily indicative of reality.

The % is misleading. Think of it as the % left of pure electric before going into the hybrid mode. It probably switches to the hybrid mode at about 20% of actual battery charge left, although it will display 0%.
If you plug into a charger that tells you the delivered power you will see >13kW even when you charge from 0% display. The battery is 16kW so at 0% display there is probably ~3kw left.

I'm glad FCA is still working on these vans, but I wish they would introduce something more useful than changing display from 0 to <1, like adding an option to use only electricity for preconditioning for the vans plugged in garages.

Or gas only for my highway portion of my commute so I can save the electricity for the city portion.

The only problem is that, for a long time, Priuses used a Nickel-Metal Hydride (NiMH) battery (don't know if the latest version still does). But I think the same principle applies.

Yeah, I think the rule applies generally to all types of batteries with some (like the Li-ion) being more sensitive than others.
