Ford Charger Pro won’t charge at 80 amps?

I installed a Ford Charger Pro recently, and the setup process with FordPass was a nightmare—it’s still pretty glitchy. The first time I tried charging, my battery was at 95% and the charge rate was only 2.7kW. It was freezing outside, so I’m wondering if the charge rate automatically reduced. Now I’m at 88% with about 10°F outside, and the rate has gone up to 10kW. On my JuiceBox, I get a consistent 8kW. Has anyone else run into this kind of issue?

What year is your Lightning? If it’s a 2024, it’s capped at 48 amps.

Yeah, I have a 2024. Why the cap?

The 2022 and 2023 models had dual onboard chargers, but Ford switched to a single charger in 2024 to cut costs. It’s still plenty fast at 48 amps, though.

I’m kind of annoyed because I bought the Ford Charger Pro expecting 80 amps. I already had a regular Level 2 charger.

Can you return it?

Not sure—I drilled into it during installation, so maybe not, but I’ll check.

If it’s 10°F out, most of the energy might be going toward heating the battery to a better temperature for charging.

Is your charger hardwired to a 100-amp circuit? Also, did you check the internal dial setting on the charger? It might not be set to 80 amps out of the box.

Yes, it’s hardwired to a 100-amp circuit. I didn’t change the dial, but according to the manual, it should be set for 80 amps by default. I’ll check when the weather improves.

@Vic
Mine wasn’t set to 80 amps out of the box—it was at 40. I changed it to 48 since my setup uses a 60-amp circuit. Your 2024 model maxes out at 48 amps unless it’s a Pro model with the extended capacity. I’d recommend checking the dial; you’ll need to remove the cover and some screws to access it.

Check the charging curve for your Lightning. Once the battery goes above 85%, the charge rate naturally slows down to protect the battery.

That makes sense—thanks for confirming my suspicion.

What size breaker are you using for the charger?

It’s on a 100-amp breaker.

It’s on a 100-amp breaker.

For 2024 models, the maximum charge rate is 11.5kW due to the single onboard charger. Your setup is normal. You can adjust your FCSP to 48 amps unless you have another vehicle that needs the higher rate.

Did your electrician set the internal dial to match your setup? If not, that might be why you’re not getting the full 80 amps.

I’ll have to check that when it warms up outside. If it’s not set properly, that could explain the issue.

If you have a 2024, it’s limited to 48 amps due to the single onboard charger. It’s working as designed.

Ford removed the dual onboard chargers for 2024 to save costs. It’s frustrating but common with newer models.
