Curious how long it really takes to charge a 2022 ER/ 2023 xc60 recharge? At our condo, we have access to a Level 2 Chargepoint station. Volvo says 5 hours. Is that realistic?

Yes. A level 2 charge station or the standard Volvo cable (with a 240V/20A receptacle) will charge at 3.7kwh. It will take about 5 hours to fill your battery at that rate.

It can be variable dependent on temperature (both ambient and battery). It can sometimes be as long as the stated time. In practice I’ve seen ours go faster but definitely slower when very cold out. The last 1/4 left to recharge is what takes the longest. In our case the stated time to charge at L2 is 2.5hrs (the battery in our 2017 is half the size of the new 2022/23 ERs. In practice it’s <2hrs from depleted net capacity. When below freezing and typical below 20F is when it takes about 2.5hrs.

I have never seen mine charge at 3.7... the best I have seen is 3.1kwh.

I connected to a 22kw 3 phases public charge. And it was charging at 3.1kwh. battery was at 45% .

Although it has a 18.8kwh battery, I think only just less than 15kwh is usable. So 5 hours @3.1kwh make sense. When battery level to close to 100%, it slows down to under 1kwh.

The Volvo Hybrids have a charging rate limit at ~3.7kwh maximum. So, even if the charging station is capable of more, the car will limit the charging rate at that...

I've done both 120v and 240v charging in my garage. On a standard 120v/15a circuit, I used the Volvo cord, which only pulled about 10.5 amps. This is probably good, because circuits are normally rated for 15a max, but only about 80% of that sustained. I then installed a 240v/50a circuit and bought an aftermarket current-selectable EVSE cable, which I use at 16 amps (about 3.6 kwatts).

On the 120v circuit at 10.5a with the Volvo cable, I got about 2.5 miles per hour of charge, tapering off at the top end. So to get from 0 - 35 miles of charge took me about 15 - 16 hours. (If you have access to a 120v/20a circuit, you could probably get an aftermarket cable and run it at 16a. I don't think the Volvo cord would pull more than the 10.5a -- but I could be wrong about that.)

On the 240v circuit at 16a with the aftermarket cable, I get about 9 miles per hour of charge, again tapering off at the top end. So to get from 0 - 35 miles of charge takes me about 4.5 hours.

I keep the Volvo cord in the rear compartment of the car and use it on travel...since it only pulls about 10.5 amps, I never have to worry about tripping anyone's breaker.

I'm always amazed by how thoughtful and informative posts on this board can be. OP asked a very simple question and a bunch of you filled in with all kinds of informative details.

Well done!

Short answer to original question - L2 to L2 cable on public charger that provides 3.7kW or more takes on T8 ER 2022 (18.8kWh battery) about 5.5 hours from empty to 100% full.

On a public charging stations in Europe - all i tried to use provide either up to AC 21kW (for slower charging cars like e.g. Volvo recharge) or from 21kw to 50 or 100kw (for purely electric) - those seem to be both AC and DC.

So i never tried high power charger as electricity is more expensive on those and I'd be blocking it for pure EV cars for a long time.

Net is - as many people said - Volvo car charger (inside the vehicle) is 3.7kW. Therefore as long as charger is 3.7kW or more 7.4kW or 11kW or 21kW - car was charging with max 3.7KW. from 0% to 100% it takes about 5.5 hours (5hours 20minutes to be precise). last few percent/10-20minutes charging is at much less power (1kw trickling) otherwise it would be in 5 hours about 90-95% full.

here is the report from 2 sessions on public charger. Second session (on top was) from 51% to 100% the 1st one at the bottom from 1% to 51%.
Net is - you add these 2 together - its 5 hours and 6 minutes for 1% to 100%. Last 10 minutes of 2nd sesion it was trickle charging at 1-2kW but 1st session (divide 8.9kw with 2.25 hours ) and most of second session charging was at 3.65kW/hour.

No big surprises ... Volvo supports 3.7kW max charging speed. Battery (user chargable) is 18.8kWh. so in ideal conditions with 16A/3.7kW charging speed it should take no more then 18.8/3.7=5.08hours = 5 hours 5minutes. I got 5 hours and 6minutes.

Temps (as its summer) were about 20-21C (optimal maybe) ... net is - if your charger (public or home one) supports 3.7kW charging speed slightly more then 5 hours will charge it from 0-100% on Volvo Recharge 2022 models (ER with 18.8kW battery).

If anyone needs more time to charge it - either chargers are not that great or other conditions (temperature ?) are sub-optimal.
