Can I Lower Charging Current?

[Science]

After about three months, our circuit breaker for charging our Lucid Air started to "pop" (the circuit breaker "breaks"). This is new behavior.

We notice on our two other (brand unnamed) we can lower the charging current with the app. We did some searches here and in general it seems it cannot be done on the Lucid Air.

Note also we never had the breakers pop on the unnamed brand car and we've had them for more than five years.

Also note that we've had some electrical storms lately. Could the circuit breaker have anything to do with ground faults?

Can’t be done in the Air unfortunately but can be done in the Gravity. Maybe one day that feature will show up for the Air via an OTA.

It can be done with third party chargers, but honestly, “breaker keeps tripping” means time to call an electrician. Especially if it got worse over time. It almost certainly means some part of the circuit has been getting uncomfortably hot and is degrading. Keep pushing it and you’ll end up with arcing, which is how fires start.

I agree that if the breaker keeps popping that there is an electrical problem that needs to be fixed right away. I would call an electrician before using it again.

Yeah...good advice. I had to replace the wall outlet. It was 10 years old and not very robust.

Please make sure you replaced it with an EV-ready or industrial/commercial outlet. Do not replace it with the $15 Leviton outlet from
Home Depot.

Standard Breakers trip due to heat. If you exceed the amperage rating of the breaker, it heats up and trips. Very simple system. It's not just a too high amperage device that causes a breaker to trip. The other culprit is resistance in the circuit due to a myriad of reasons: corrosion, loose wiring and as we have seen too often, worn out contact blades in a receptacle. In the hi fi equipment business where I advise, we see many electrical issues resolved simply by removing the old crummy receptacle, cleaning wires till shiny, and using a new heavy duty commercial grade receptacles with screw terminals properly torqued.
