HV Battery Charge State

[topgun/goose]

New Maverick hybrid owner. I was seeing what different things I could look at the other day on one of my short drives into town and back which is about a total of 35 miles round trip. Found the EV coach screen and after a bit figured out how to tell the charge state of the HV battery. Well I have about 250 miles now on the truck and have yet to take it on a long trip on the highway. From the view in charge mode which shows the position the two vetical lines are in at full charge it appears I have not gotten more than about half a charge into mine. As soon as I see electric mode the bars are half as wide as they are in charge mode. And therefore it doesn't take long in electric mode until the two bars are at the minimum distance apart and the engine has to come back on. It was interesting watching them grow closer and closer together, as they get closer you have to back off on the throttle to delay the starting of the engine. It was a learning experience for sure on how it all works together to keep the little truck running smoothly down the road. Looking forward to next week which will be the first road trip of about 250 miles round trip. It has been a slow progess but the combined average has finally gotten above 33 mpg, did see mpg on trip reading of 99.9 once and that was fun.

Loving this little truck so much. Being able to haul stuff and get great mileage is so great. I spent about two months looking at different vehicles before deciding on the Maverick as the replacement for my aging Focus with 300,000 miles on it. And I feel like I chose wisely.

You didn't post your location, but assuming you live where one has actual winter weather, your mileage should improve a lot once the temps warm up and you don't have to run the heater.

Search the forum threads for "pulse & glide" driving, to maximize Hybrid non-highway MPG.

While that is for the Power Meter you don't have exactly the same view of, the info and methods, and probably the same values at some point on newer power meter - still apply.

Might help understand the EV Coach too.
Which I'll add on the older style - the Recharge bar length never matched the Battery usage bar length either.
Pretty sure more length given to the usage so you can attempt to stay under the level the ICE starts, whereas on braking/coasting recharge not as much range needed to stay in it.

On recharge - as long as in the box you are getting the max you'll get, whether that is a long coast down barely dipping into recharge, or a harder press almost maxing it out. Same amount of Amps put back into the battery.

Also - it's not really giving the charge state, though as you mentioned longer is more fully charged, but would be hard pressed to glance and see if the blue section is as long as possible meaning fully charged.
Because as soon as you switch to EV mode the bar starts reducing.

Oh - some other info.
If your desired power (go pedal) is within range of using EV mode (below 10% if fuller HVB), but the charge is below 40% it'll keep the engine on until back to 40%, then it'll switch over to EV mode. And at 30% it'll turn ICE on again.
So you kicking over to EV and seeing small bar - that's probably what's happening. You are getting the 40-30% usage range.
Whereas if ICE was running for heat or needing more than 10% power, or long coast or braking then HVB may actually charge on up to 70% - that's the max bar size you'll see sometimes.

Crude and not linear.
But it is somewhat helpful.

That bottom one is 70% with 72% the maximum ever allowed and only occurs when braking on a significant downhill.

Here are a couple of older threads on charging that I found informative

The max hybrid SOC that I’ve hit was 74% on a one mile downhill glide/braking as measured by my OBDlink dongle. Never could get higher than that.

I can get that longer bar solid at a couple parking spots reliably, on 1st startup, and not so cold the ICE turns on immediately.
One parking spot proceeded by decent coast down to it, other barely above 10% power usage ICE running and full charge by the time I park.
I'm not sure I've ever enabled the scan logging because usually part of short trips I don't bother with, so not entirely sure what SOC is claimed when well beyond normal.

ETA: had one yesterday on startup ready to drive off. 64% SOC.
Despite the line being much longer than full would be.
Wondering if a glitch, though sometimes when it starts like that I can go above the 10% power and not kick on ICE.

Keeping it between roughly 70 to 30% charge is by design, to extend the high voltage battery lifetime. Like any lithium-ion battery, you never want to charge or discharge it fully, because it shortens the lifetime of it.
