Suddenly charging at 3.3kw and not at 9.6kw

[Baja Lightning]

I plug in almost every day to our Ford Charger, but today I am only charging at 3.3kw (16a) as opposed to the normal rate of 9.6kw.

What can be the problem?
Is it a Ford / truck issue?

Charge rate is set to 48a,

Make sure the FCSP firmware is up to date. There was a firmware version a while ago that had that exact symptom. I had it happen once. Updated firmware and that cleared the problem. Other people have reported the same thing.

Though your charger is set to 48a, and assuming it's a FCSP, there is a 'software' setting in Fordpass, that can be corrupted, or stuck at a lower than optimum rate.

You can find this under the Energy tab> Charge Station> Settings> Max Charge Current> Edit> slider to the right most available level> Save

You may need to repeat the adjustment a couple times and power cycle the EVSE by turning the circuit breaker feeding it OFF > ON to make the change stick.

If that does not work. test the trucks ability to charge on Level 2 equipment at a public charging station to see if you get better performance, take note that some of these units are also limited in amperage.

I would cut power to the charger via the breaker to give it a reboot then measure again.
