Estimated charge time for Level ll (home charger) for BEV or EREV models?

[ArtL]

A little off topic: Any info (or guesstimates) on what the charge time(s) might be with a Level ll (home charger) for the BEV or EREV configurations - haven't found any pre-production projections (maybe not looking in the right places)?

That will vary depending on the wiring/breaker/interface used.

Typically EVs come with a mobile connector (most call it a charger) that is usually capped at 32A. You can find some third-party devices that can hit 40A.

Most people will opt for a Wall Connector (again, most people call them chargers) and these can offer varying charging speeds. The actual charging speed will still be dependent on the vehicle's on-board charger. Next the breaker and actual wiring will need to support the desired/max charging speed of the EV.

For instance some of the early Teslas had dual on-board chargers and could hit 80A if the wiring and breaker supported it. Most EVs sold today will be capped at 48A from the on-board charger.

I am going to make a few assumptions.

150KWh battery size (EV Only)
48A on-board charger
6AWG THHN/THHWN wiring with a 60A breaker
Wall Connector (Scout brand or third-party) that supports 48A

At 48A charging that is a roughly 11kW per hour charge rate. So if you could get your battery State of Charge (SoC) to 0% and you wanted to charge to 100% it would take around 13 hours. Most people will not be arriving home at 0% and charging to 100%. For the EV only if the batteries are NMC chemistry then you will want to limit your max charging to 70-85% for daily driving and only go to a higher limit for longer trips.

The average driver is probably going to need to charge from 40/50%-85% as a guestimate based on my past experiences with Tesla and Rivian EVs. Let's just use round numbers and say the average Joe or Jane will charge 30-40% each day for their daily driving needs.

This means they will need to charge, on average, 30-60kWh each day. So the average person will charge for 3-5 hours to be ready for the next day.

There are a lot of variables and unknowns that can affect those numbers, and as time goes on it will be easier to get more accurate numbers.

I just leased a Lightning standard range (98kW) so I'm experiencing this charging now. Using the mobile adapter that came with the truck I'm pulling 1.2kW on a regular wall plug adding 2.5 miles per hour of charging overnight which is actually sufficient for my daily commute.

I'm waiting for the electrician to come install the Charge Station Pro which will be on a 60 amp breaker, providing 48 amps (80% rule) to the charger to give me 11.5kW charging around 25 miles of range per hour of charge. The charger and installation are provided at no cost from Ford, so I'll have all the infrastructure ready when the Scout arrives around the time my lease is up.

Check out the State of Charge channel on YouTube, great info on home charging there.

The bigger the vehicles battery pack, the longer the charge time.
The Emporia wall charger has a fussy to use app and it's 100% controlled by the app.

Though set for 48 amp charging, it would default to 32 amps.
So we had to keep resetting it each charge.

Jus' sayin' in case someone has the Emporia charger.

Customer service can be helpful, it can be not so helpful.

I'd like a control interface on the wall charger but haven't found one with that yet.

I can't wait to have my first EV when I'll be able to energize the vehicle at home and avoid going to gas stations to refuel.

With my typical use case (about 25 miles per day), I may be able to get away with level-I charging most often, and at times when electric rates are at the lowest level. This should be about 10 hours over night, on most days.

Slow charging like this produces less heat within the battery pack and keeping the SOC between 20% and 80% may help preserve the maximum potential battery capacity for a longer period of time over the life of the battery.

Good take.

I have Emporia level 2 chargers on n both homes one outside mounted on a fence pole other in garage 499 bucks great mobile app and at 48amps with 60 amp breaker it charges Volvo in 5 hrs because of cars interface. But the EV's all have cooling systems fans etc while charging to keep battery condition. Not hard to install you can use pump cable for exterior runs no need for conduit.
