Probably not for everyone… but was surprised on how well it worked for us.

My dad now drives a PHEV kia suv. It’s good mental enrichment for him, seeing how he can manage to avoid the gas engine from turning on.

There have been rumors of BMW going the “range extender” route (i.e. the gas motor is relatively small and used to charge the battery), which makes more sense for my use case.

So I’m “just” 12 years ahead of you.

Yeah… knowing the cities you live and work in a phev makes a ton of sense. If I were still commuting to Palo Alto (where I used to work) I’d go for the same.

My wife and I are still loving our hybrid cars. They suit our lifestyle best. 13 gallon tank with a 500+ mile range for combined, city, and freeway. We gas up our cars around once a month or so, taking just a few minutes.

I may have mentioned this, but the Ford Escape PHEV seems to be an ideal vehicle. It will fully charge on a 120 outlet in 10-11 hours. So basically overnight. It only has a 40ish mile range, but if you live less than 20 miles from work, you will rarely buy gas. And you can choose which power source you want to use. So you can use battery to get you out of the city and then change to gas for rural roads. Or let the car decide.

They really need to make a Maverick PHEV.

my last few cars were an eagle talon, porsche boxster, and tesla model s. My wife’s i4 is plenty fast enough for me. And whatever it gives up in pure speed it makes up for in driving, comfort, and features.

One of these things is not like the other. LOL.

Do you guys stick with OEM tires on your vehicles?

when i need to replace my tires, I get whatever equivalent tires I can find. Especially because on my tesla they end up getting replaced after a year anyway.

On the Porsche I was more careful, mostly because different brands had different noise profiles and I made the mistake once of buying very loud tires and then I was stuck with them for a few years.
 
We were thrilled this Keys trip with the EV (DCFC) infrastructure (doesn't come up for us that much as we only do a couple of 250+ mile on way trips a year). We headed down to the Keys via 95, then back up to Orlando via the turnpike, to break up the trip home, Stayed at Cabana Bay at Universal (Orlando). Chargers everywhere.

Last trip to the Keys, I was being a goon with only wanting to stop at a freebie EA stations, but in FL, there are so many public DCFCs that are only $0.30/kWh. We did ~840 miles, paid at FPL on the way down (major stop, had lunch, 35 minutes to full - in fact, I moved the car from the charger to right outside the restaurant), then free at Cheeca in the Keys, then paid at ChargePoint (just a 10 minute stop so we'd arrive at Cabana Bay around 20-25%), then free at CB (back to full), and factoring in the cost if we topped off at home back to the departure charge we did the trip for $0.05/mile 🙂

I still contend that without home charging, it's very questionable to own an EV, but if you can get that setup, so many trips that require a DCFC stop/stops, are still not that much different vs. ICE 🙂

FWIW, pics coming in a different thread, trip was amazing, stayed at Cheeca resort again.
 
We were also just up in the PGH, flew out of Sanford (SFB), took the Wrangler, wanted a little "mileage load balancing", but also for < 2 hours, it's plenty comfy and I love it's PARKING INVINCIBLE :ROFLMAO:

We did stop and stay over at the BIL's in NSB on the return an already late flight ran later, and I was done with driving after 30 minutes (at 1am ...) vs. the full 2 hours to get to our house.

(Jeep is a PHEV, so sort of on topic ...)
 
Offspring’s Mach-E just hit the lot. I knew it was getting close to time, but it just showed up today.

She will be in Saturday to pick it up so I need to get on the stick and get a charging outlet installed in the garage.

I noticed reading through some stuff that Ford only recommends DC Fast Charging when needed and not every day.

Is that typical of all EV models or just the ones with LFP batteries? It does say they can be charged to 100% daily vs 80%.

Lithium batteries in general don’t like being charged above 1C, and tend to age faster when they are. For a 90kWh battery in the extended range Mach-E, 1C is 90kW. So if you are fast charging regularly, that means you are also likely exceeding 1C regularly. Ford’s charge rates are a bit more conservative than other brands where top speeds can get upwards of 3C, but the advice is still up to date with my knowledge on battery aging.

DCFC is also the most expensive way to go unless it’s on someone else’s dime anyways.

It really depends on the chemistry too. The batteries Tesla uses don't seem to care as much about DCFC as they do calendar aging and sitting at 100% (for non-LFP chemistries).
 
Just use it however you like, people get too weird about charging. Your typical DCFC sessions are probably a small percentage of charging anyway, and if you don't have home charging (to avoid constant DCFC), you shouldn't be buying an EV anyway :)

There are some differences, but it also gets muddled in the fact that we are also still learning how much cooling loops in cars help battery packs in DCFC situations, so while any battery doesn’t generally like being charged above 1C, heat is a big reason for that. One reason phones now include thermal management when fast charging so it can throttle charging in >1C situations when the heat starts building up. Many/most EVs include a coolant loop to either heat or cool the battery to keep it as close to the ideal range as possible, on top of other thermal management, which should help. But I still probably wouldn’t want DCFC to be my only charging method unless I had no choice. In my area it is 4-5x more expensive for one.

But yes, data around NMC seems to say calendar aging is the primary component of battery age in normal use. The ID4 owners forum has been tracking this for a few years now with folks that have OBD readers and sees a similar trend.

I don’t think anyone in the thread was taking it that far? The question was about daily DCFC, not occasional DCFC.
