Bolt!

The connector between the two isn't very stiff or sturdy, so that alone probably warrants replacement.

The subpanel has a breaker on the main panel that keeps tripping, even after I turned down the amp setting on the charger. Might need to replace it, hopefully it's just old and a new one might fix it. It's a double breaker and only 1 side is tripping so it seems like an age issue.

What's the breaker's limit and what are you trying to run the charger at?

I'd turn that off pronto.  The charger is only getting 1/2 voltage on that odd config, which means if it doesn't trip off the breaker that on is pulling 2x the amps which could lead to a fire

I'm just guessing that as soon as the one phase breaks the charger shuts off so the other power is safe?

[CaminoRacer]

40a breaker, so I'm well under the limits. Started at 32a, went down to 24a, and now I'm at 16a and it's finally not tripping.

Yeah the charger shuts off

I'm guessing there's been an upswing in people scrutinizing their electric feeds: capacities, panels, breakers etc. I think these L2 chargers can go to 48A - which needs a 60A double-pole breaker.

Especially in my 1974 house.
I realized this week that most of my house project list is electrical. Car charger, lighting in a few rooms, replacing old outlets/switches, and eventually solar and battery storage.

Is there a way to limit the AC charging rate in the Bolt?  I know Teslas have the feature because they are famous for owners not doing it and tripping off L2 chargers

If you can it should be limited below 7.5kw/h

My son's in a 1955 mid-century modern. They had to get the utility to bump up the gauge of the service feed to something like 250A to accommodate all the upgrades they were doing inside, which included an EV charger outlet.

Earlier Bolts are limited to 7.7 kw charging (2023 models can go up 11.5)

Yeah I'm gonna need to increase from 100a to 200a/250a for solar/battery storage. I think I might be lucky and it'll be cheaper than usual, since the wire to the house is above ground and the breaker panel is next to the meter, so it's all right there and easy to upgrade.

My question was if you can limit the charge rate in the infotainment somewhere like a Tesla.  The Bolt is capable of pulling in way more than a household L2 will provide.  A Tesla is similar and owners need to manually set a limiter.

My experience with installing Chargepoint chargers is the chargers are massively poor at self limiting and cars by default will try to pull as much as they are capable of - and in the case of Tesla will trip breakers if not limited.

Installers have an app they use when commissioning the Tesla wall connector, where they set the breaker size. If they did that right, the car should never pull more than the connector tells it it can handle.

The Bolt's onboard AC charger is only 32a/7.7 kw. Only the DC charger can go higher

Keep in mind 7.7KW is a full 40A or more depending on power factor.

The power factor is over 9000

A new 50a breaker on the main panel seems to have fixed it. The wiring between the panel and subpanel is beefy enough for even more than 50a, which is surprising but nice

[Eye of the Tiger]

A larger fuse easily solves many electrical problems.

[CaminoRacer]

A new 40a would have fixed it too, but might as well match the subpanel's breaker.

The Bolt's windshield washer pump wasn't working last week. It has two pumps, for the front and rear, but they share a fuse. Neither was working, so I checked & replaced the fuse. It all works fine now, but I'm curious if it will pop the fuse again soon. I hope not, because I think replacing the pump(s) would require removing the front bumper.

[CaminoRacer]

I finally replaced the headlight bulbs today. The driver's side HID bulb has been on & off since this summer. Replacing them involves almost taking off the whole front bumper to get to the last bolt holding the housing on, since there's not enough clearance behind the housing to swap the bulb while it's in the car.

Took about 2 hours to swap both bulbs, but I think it would only take an hour if I did it again. I've heard shops charge $500-800 to do the job, definitely not worth paying that much. I got Hella bulbs from RockAuto for $40 each.

I'm hoping the bulb was the issue and not the ballast, otherwise I'll have to take it all apart again and the ballasts are like $130.

The car has 121k miles now. All the EV stuff is still rock-solid but the other normal car parts need some maintenance now, as you can tell from the last page or two of this thread.

... suspension bushings, steering bushings, dampers. The degradation introducing slop & looseness so slowly you don't notice it.
