Honestly, I have no idea what the actual capacity is on any given day. In my normal around-the-city driving, I rarely go more than 30, and I have almost never "run out." I tell people my car is an EV 300+ days a year.

I don't know if the BMW shows this, but you can see miles/kWh on most EVs. It is a much better indicator of range than the guess-o-meter.

You can honestly drive yourself crazy with range stuff. I think plug-in hybrids are a smart move right now, especially if most of your average driving is commuting to the office with occasional longer trips.

My unsolicited advice is not to pay much attention to the range. Drive it and enjoy it... punch it occasionally or all the time if that is what you like.

I guess lets see how it improves or not, I hope battery doesn't need service.

Mine was exactly same as yours the first few days out of the dealer. Now two months in, it's exactly like everyone else reports here.

One thing about the L2 charger: For this car, there's no point in putting in more than a 220V-20A circuit because the car can't use any more amps than that. Only reason to put in a higher amp circuit is if you think you might get an EV that can pull more amps.

Also, there's no point in spending $600 on a fancy EVSE. I got this one for $180 and it gives me a full charge in 5.5 hours just fine on 220/20.

Depending on how far the wiring must run, the labor is pretty much the same if you run 12g or 6g (but the price of the wire itself will go up!). It highly likely your next PHEV or EV will accept more power. You can install a smaller EVSE onto the heavier wiring, but you can't put a bigger one on smaller wiring. So, depends somewhat on how long you think you'll be there what you install. There's something to be said for a larger EVSE, drawing less power, that might last longer, but that mostly depends on the quality of the unit you select.

I agree here. Just use it as intended. Usable battery is 17.1kWh, max charging wattage is 3.7kW? However long it takes to charge that depend on your EVSE.

To answer the highlighted part, yes 45e show this, but it is a misleading number. It uses the total milage driven (EV + ICE), divided by kWh usage. So if you did some mixed driving, you will see a very high number, makes you think you beat Tesla in mi/kWh.

Mind sharing your trip computer screen shot "since factory" setting?

Being new to hybrids/EVs of any sort, it has taken me 6 months or so to get to this point. I now know for certain that I can do my daily chores on electric only, no matter what the reading shows, and if for some reason I run out of juice, the machine will just flip into hybrid.


And I d love driving the car, esp in electric mode. It is so quiet and smooth. The ICE loaner the dealer gave me felt archaic. YMMV

The noise is something I'm definitely getting readjusted to! That, and missing instant torque. With that said, the ICE X5 is no slouch... it just announces its intentions

I think you have the right mindset on range. If you didn't watch the estimated range in your ICE, then don't do it now. It is a little different for a full EV because you can't pull in and charge everywhere, but no reason to worry about it much with the 45e.

I agree... if you plan to live at your current home for the foreseeable future, it is probably worth putting in a high amp breaker and wire.

A 60A breaker (assuming you have the capacity) and appropriate gauge wire will be nice for the future (48A charge rate on supported chargers). I believe that you get a one-time tax credit (not full credit) for installation and charger, too.

It's IRS form 8911: https://www.irs.gov/pub/irs-pdf/i8911.pdf

Generally the smaller of 30% or $1000.

I saw this from you a few times, but never the trip computer from “since factory”. It is life time consumption, representing the real life usage. In your case 13k miles. The range number from EV mode can be all the place. The can archive 50-55 here if I choose to.

I have posted since factory actually on another thread. Cannot remember which one…

My factory results are skewed to a lot of ICE driving as we took the vehicle on a cross country trip. Actually makes miles/kw look extremely high (double digit high); whereas the 2.7 miles per kw is VERY representative of our EV usage around town.

Going on memory we're probably about 9,000 ICE and 4,000 EV.

PS- You and I have already danced this dance. My factory numbers are posted in thread "45e and auto journalism" (or words to that affect) mpg results.

With that screen info, we can back calculate the actual kWh used. Then we can use total EV miles / kWh to get a better representation of mi/kWh of the car.

Just finally was able to get back to 100% on stock charger. App shows 27 while in car says 24. Its not crazy cold either and car has right now about 80 miles. The capacity shows full.

I went and got a 320$ charger but after looking back on the thread Im thinking to down grade, but I already have a 20a circuit to 14-50R. So looking maybe for a cheaper solution for that. Or maybe change the circuit.

[jad03060]

I think the X5 shows the amount put into the batteries, but the app might take into account power that was used to provide cooling and that lost in the conversion process. You'll always put more watts into the vehicle than eventually get into the battery. That depends some on how hot/cold things are and the capacity of the EVSE. A level 1 device is less efficient getting the high voltage DC needed to charge the batteries versus starting with 240vac versus 120vac.

curious about your XC90… how fast was its charger (in kW) and how many amps could you pull from its EVSE while plugged into your household outlet?

the 45e's on-board charger is 3.7kW. its included EVSE maxes out at 10A, so the charger can't go any higher than 1.2kW. also note the XC90 battery capacity was 9.2kWh which is almost half of the 45e capacity, so all things the same, of course the XC90 will fully charge in less time.

if you absolutely need it charged overnight, your best bet would be to get a L1 16A assuming you have a dedicated 20A household outlet for it which will fully charge in ~11h, or a L2 which will take 5.5h

I honestly never paid attention I would be able to go from O to 100% over night and never even cared, there was a point where I was preping to buy a L2 and did install outlet and circuit but only at 20Amps and never went thru with getting a charger this was few years back as getting charged over night was more then sufficient.

Looking at specs its a 11.6kW so at 120 at 10amps over night about sounds about right. Here at 24kW closer to over double sounds right.

Also any tips for maximizing the range on electric? What are your guys default settings?

[jad03060]

Drag goes up non-linearly with speed. IOW, the faster you go, the less efficient.

Driving smoothly versus small speed-up/slow-downs when possible, even with regeneration affects range. Precondition while plugged in when you can.

Using the seat heaters versus keeping the whole cabin warm can make a difference, and having the rear seat heater option can help keep people from complaining back there.

Acceleration isn't a big energy user, but overshooting and then having to slow down is. An ICE tends to be less efficient during acceleration, but an EV motor isn't significantly different in overall usage.

Don't rush up to a stop sign or stopped traffic and use the brakes...regen helps, but coasting is better and you'll still be producing regenerative braking, but for a longer time. If you time it properly, you may not have to stop at all.

Once the cabin is where you want it, Eco mode can help as it makes the throttle less sensitive, so fewer spikes of current requested, and the HVAC will be less aggressive.

Or, just drive and don't worry about it!

you've got a 20A outlet for L2? then can get a 16A L2. check out clipper creek

No I got a 50amp outlet a
On a 20amp circuit. But I can just add a 50amp circuit and I have the plug already, or replace the plug and I still have dedicated 20amp outlet.

Im looking at chargers and thinking to get a lower 16amp one for about 100$ cheaper but not smart at all and only 240/16amp. While I got a smart one for 300$ with 110-240 10-40amp (not that this applies much here.)
Any recommendations for a cheaper smart one with low 16/min/max/amp you guys use or see in sale now?
