Slow charging with Autel 50A

[kcoates2]

Does the Lightning automatically charge to the highest available amps available from the charger or is there a setting on the truck to select the kW? Only getting a 3.7kW charge and trying to figure out why.

There is no setting on the truck. Yes it normally goes as high as the EVSE says it will go. To see more detail you'd have to use an OBD dongle. Using that you can get more specific info about what voltage and current is available.

What SOC is your battery at? It will slow down above 90%. Also the Autel app allows you to change the max current so verify that it is set to 40A (on a 50A breaker) or 48A (on a 60A breaker).

your EVSE probably has it's own internal or adjustable AMPERAGE setting...

SOC is at 44%. Charging at 3.7kW.

So it's either pulling 15 amps at 240 volt or 30 amps at 120 ... hmmm????

You can't select the charge rate in the truck or with the Ford app. When you plug in the truck to a Level 2 charger the truck will tell the charger it can accept 48a at 240v or 12a at 120v. The charger will then supply what it's capable of up to that level.

It's unlikely there's an issue with the truck. It could tell the charger to slow down. I don't think it slows L2 charging even up to 100% (I could be wrong). It may slow it down if there is a fault or possibly if the battery gets really hot and it can't cool it down. I haven't heard of many issues with slow L2 charging that were truck related.

Check you charger settings and see if the charger app gives real-time amp output (my Emporia does). I noticed on mine the charge rate dropped. I swapped to my mobile charger and the rate didn't drop. I finally determined that my wall charger was getting too hot in my garage. I put a fan aimed at it during charging and the problem was solved.

I'll bet the Autel unit is charging at a default 16A/240V minimum setting. It probably needs to be configured for the the correct capacity of the circuit.

download the quick start guide. It shows the correct rotary dial setting for the desired amperage. https://cdn.shopify.com/s/files/1/0...-in-body-holster-quick_guide.pdf?v=1659462464

Was the wall charger noticeably hot to the touch or did you do a laser temp?

Did you check the Autel app to see if the output current is set to 40 or 48?

The communication for J1772 is from the charger to the truck. The charger advertises its maximum current and then the truck takes what it wants up to the limit. The only communication from the truck to the charger is start/stop.

It wasn't hot to the touch; it felt warm, but it wasn't so warm that make me immediately think it was overheating. It got up to the 90s in my garage so I had a theory that maybe the charger was too hot. Didn't have any more problems after I put a fan blowing on it.

I couldn't find any information from Emporia that the charger would slow down if it started getting hot. I just read that it could shut off. I thought about reaching out to them to see if the behavior I was seeing was expected.

The garage is insulated, which goes both ways, so when it get hot it stays hot. We like to keep the doors closed for security. I'm planning on putting an a/c system in there before next summer.

Oops. I knew that, I don't know why I got it backwards in my post.

That's good to know. Mine was not hot to the touch, but it was about 90 degrees with the laser temp. I'll try the fan method. Thanks for the tip!
