110 Volt Charging

[ageevt]

Good Afternoon All,
Just wanted to hear peoples thoughts on 110 Volt charging, although it takes longer when you have time is this better for the battery life and will it give you more range verses 220 Volt charging at home?

It's slow as balls and not any better for the battery than 240V charging. There's not enough power from it to run the 6 kW heater for preconditioning. So it's a waste of time IMO. If anything, the range will be less on 120V because the battery can't be completely heated.

120V is really only better than not charging at all, that's about it.

Or put another way, if you can get by with only 110V charging, you should probably not have bought an EV since your usage will not offset the extra greenhouse gas emissions that building the car entailed (as compared to building a similar ICE vehicle). On average, an EV needs to be driven about 10,000 miles (16,000 km) per year to be greener than a similar ICE vehicle.

110 V charging is only around 70% efficient so a lot of wasted energy. Of course if you can get by with 110 you are not using that much overall but still wasteful compared to 220V which is over 90%.

120v charging gives the large battery about 29% per 24hrs whereas 40a 240v charging will do about 10%/hr. If you're able to use the factory chargers 120v plug connected to a 15a 240v circuit, you can get about 66% in 24hrs.

I notice you’re in France. Is 110/120V even an option for you?

I was all fired up for installing a 240v outlet when I got my Mach E, but I'm now 5 months in now and 120v is enough for my driving.

I only go about 10-15 miles per day, so 240v is overkill. I'm sure I'm in the small minority of use cases, but for me 120v is all I need.

You may want to consider efficiency. There is overhead just to run the systems in the car needed for charging. 120V charging uses about 1.4 KW with a net charge rate of about 1.1 KW. So about 21% of the electricity you are paying for is wasted.
Charging at 240V, 32A yields about 7.2 KW with 7.6 KW input. Less than half the losses.
These numbers may not be exact in every case, but the concept is sound.

Wow, I did not know that. I bought it more for the performance than anything, but thought it was greener than an ice vehicle. I have 8700 miles in a year and a half. Just curious, is there a break even point if I drive it enough miles/years? Planning on driving it till the wheels fall off.

I used a 120v line to charge a Prius Prime. It took about 5.5 hours to charge the the small battery. I then installed a 240v line and it took about 2.5 hours.
That same configuration charged my MME 20 miles per hour.
Then I installed a 50 amp breaker with a Grizzl-E and the MME charges over 37 miles per hour.
It makes little sense to buy an EV and not upgrade to a 240v and and a larger breaker.
To me the cost of the Grizzl-e and the 50 amp breaker is well woth the time I save.

If you do not drive too many miles a day and can charge all night 110 does work fine for many. Even the efficiency differential needs to be balanced out between the cost of the 240V installation and any energy cost savings which if you are not using your car much is small. But if you purchased your EV to go green then wasting energy should also be important. All that being said I have come to realize that for many the 110 option works fine. I wonder how many go that route now that the EVSE no longer comes with the car?

Obviously is varies from vehicle to vehicle, but what I've read is about 10,000 miles per year on average. Of course you driving your Mach E more isn't the point. The point is replacing miles that would have been ICE miles. It's all complicated. I too didn't know this when I bought my Mach E and I average a bit less than 10K miles per year. Had I known, would I have still bought the Mach E? Hard to say, honestly. But I sure am glad I have it!

Thanks very much for the info, much appreciated. This is the first car I ever owned that I get a little sad when I arrive at my destination. So agreed, I’m sure glad I have it.

I keep the factory charger sitting in the frunk with just enough cord loose to plug into the vehicle. A 50' 14ga extension cord bundled up in it. Both cords route out the front and allows for easy extension cord connection while the frunk can close 1 click. There's not enough space to take either the charger or the cord via this method, also keeps water out. If I need to do light charging there's very little to fool with. Only thing needing attention is to arm wrap the extension cord.

10,000 miles per year is not required to break even on emissions, and depending on how you count emissions EVs can be cleaner starting from Mile 0. The large majority of emissions in a vehicle's lifecycle are tailpipe emissions, and the relative savings vary significantly by region. In general, less driving is less emissions. And it's nearly a myth that the indirect/non tailpipe emissions for EVs are higher than ICE vehicles. See third link below.
