Ordered Extended Range Battery, Got the Standard

[RickMachE]

Mine has a button,

I also ordered an extended battery and so far can’t get a charged over 270. How can I tell if I receive the extended battery? Is there something in the vehicle registration in the car that I can check?

You got the extended battery.

I'm in Michigan also. Your 270 is what you get. And, you should not be charging over 90% unless you're headed on a trip.

Imagine if you will. Let’s say the wrong battery did get installed on the assembly line. What would this do to the cars system? Throw some codes? Is this even possible to drive? Software would be installed for the ER battery. Theres more cells. This would have to throw a code no?

It would be just like if there was a real Nigerian prince that needed to move $10,000,000 to the US……he’s SOL!

Why not charge to 100%

Why not charge to 100%

Read your manual.

Why not charge to 100%

Ford recommends charging to 90% for daily use (it's in the manual), 100% for trips where you need the range, to preserve the battery longterm.

Why not charge to 100%

because doing this to lithium batteries reduces their life. Same thing happens to your phone and PC BTW. There are lots of threads on this.

They don't like:
Being completely full
Being completely empty
Being real hot
Being real cold

among other things.

I have extended range AWD. In winter, when outdoor temps dip into single digits (outdoor is where our Mach-E is parked year-round), I'm lucky to see 100% battery range get above 200 miles. I normally charge it to 80% though to preserve battery life.

I'm pretty sure you have the extended range, and welcome to the world of EVs, where nothing is as it's marketed.

We're happy to help here at the Mach E Forum with just a few simple questions! First and most importantly, what color is the car?

I should start a battery verification service. Seems like I could have a lot of business...

An estimate of the battery capacity is to use the data from a charging session. Record the KWhr added (KWhrA) and SOC before (SOCB) and after (SOCA) charging session. The battery capacity (BC) can be estimated with:

BC = Neff*KWhrA/(SOCA-SOCB),

where Neff is the charging efficiency of the charger. My Charge Point Home Flex seems to have an 81% charging efficiency so Neff = 0.81.

For example, my last charging session added 26 KWhr and the SOC was 77% and I charged to 100%. The battery capacity can be calculated from,

BC = 0.8*26/(1-0.77) = 91.6 KWhr which is close to the usable capacity of the MME extended range battery.

If you have a standard range battery, then this calculation should yield around 70 KWhr.

The ChargePoint Home Flex EVSE doesn’t convert AC into DC to charge the battery. The actual charger is in the car. The efficiency of the car’s charger is actually closer to 91%. If you are seeing 80%, then the extra amount of power that is pulled from the wall is being used for running the battery’s thermal management system. For instance, charging in cold weather will require heating of the battery to a more optimum level for charging.

I would not necessarily go by what the Ford app says for SOC and kWh added. Truncation of the SOC is happening. 70% might be 70.0 or 70.95. Same for kWh. If you want an accurate figure, get a Bluetooth OBDII reader, a copy of the CarScanner app, and use that to get actual before/after kWh to empty figures, and then pull data from the ChargePoint for kWh pulled from the wall.

Before you pile on a question, try reading the 10 pages of discussion that's already there.

There’s an X on the outside of your front doors.

Thanks for your thoughtful and considerate reply?

I stopped around page 8 so maybe somebody said this, but I think this definitively proves why Tesla does their range estimate the way they do.

Yeah, it has been a common debating topic here. And check this out:

Ford does a pretty good job with the GOM, and Tesla does not. But Tesla drivers are not going on forums to find out if they have the wrong battery either.
