Home Charging

[marcheLLL]

I usually charge it at home with a 240V, 30-amp charger. Before, it would charge from 18% to 22% in like 3.5-4 hours, but now it's taking longer. I first noticed this around late June when we started using the AC more. But looking at the data, it doesn't seem like anything's really messing with the charging. I've been using the same charger and the garage temperature has been going up steadily.

I'm using a regular NEMA 15-40 outlet. I've heard people talk about using a fancier NEMA 15-40R outlet, but I'm not sure if it's worth it. The temperature difference between the two days wasn't much.

I'm wondering if everyone else's ACs turning on and off might be messing with the voltage, which could be slowing down the charging. Has anyone else had this problem, especially during the summer?

You know that sometimes the connectors of the NEMA can loosen over time. This is why you are noticing slower charging. Indeed, it is a better idea to think about a receptacle that can support the high-amp draw that EV chargers require.

The garage heat could be making your EV battery manage itself more conservatively, which slows the process down. Also, voltage drops due to higher AC usage (yours and neighbors’) could be limiting the power reaching your charger. If you have a smart charger, you might be able to monitor the incoming voltage directly. A quick call to an electrician to verify the outlet’s performance during peak usage could help pinpoint the issue.

It sounds like the warmer garage temperature could be affecting charging efficiency. AC cycling might cause slight voltage fluctuations, slowing charging.

Have you checked if your NEMA 14-50 outlet is getting hot? Your Ford app might show the plug's temperature. That's usually the first thing I'd look at. Also, did you double-check that the wires are all tight where they connect to the outlet? Just want to make sure everything's hooked up securely.
