Default Charge cable issue and general questions

Hello everyone,

My wife and I just purchased a 2023 XC90 Recharge and find the charging cable quite finnicky. We're currently utilizing the 120V charging adapter and we tend to leave the charger plugged into the wall outlet in the garage so that when we get home, we simply hook up the charger to the car. The issue is that when we do that, the charger doesn't seem to function, we physically have to go into the garage, unplug it from the wall outlet and plug it back in and then it will start charging. There's also the issue that it'll be charging and then randomly stop and the LED on the outlet portion will flash red... Are others experiencing the same issues? I'll eventually purchase a chargepoint charger since the 13+ hours of charging isn't cutting it.

I also had a question regarding driving on PURE and then running out of battery and switching to the engine. Does the engine get warmed up enough to safely be running at the current speed/rpm on a random jump? I just fear that in the winter time, the engine won't be warmed up at all and then randomly jumps on while cruising on the highway while still being cold. This would not be good for the motor in long terms.

Does the computer separate what mileage the vehicle has made on the electric motor vs the gas motor?

Thanks

Mitch

1. I think this might be an issue with the circuit itself. It could be the EVSE unit, but that's unlikely since these things are really just glorified plug adapters with some built in power quality checks. I suggest having a dedicated 240V circuit installed and then seeing how it works for you. You'd need one anyway if you were going to upgrade to something like a Chargepoint system (and honestly that system won't charge your XC90 any faster than the included adapter).

2. Yes - the engine is designed to fire an immediately provide power. However, the engine computer derates the output a little during a brief initial warmup cycle. Fluid pumps are electric, so it's not really analogous to a 100% cold start. In fact, in winter, the electric heater heats the coolant in order to provide cabin heat through the heat exchanger. Not super efficient power utilization, but it is efficient in terms of packaging and complexity.

I totally forgot to mention that the dealership couldn't find the original charger that came with the vehicle so they gave us one they found laying around and ordered a new one for us; It is possible that the one they lent us is defective. I'll see when they provide us with the new cord if it changes anything. Oh I see, the Chargepoint is just a fancier charger. I already have a 240V outlet laying around so all I need to do is run some wire to my panel and pick up a 50 amp breaker, should be pretty easy!

That makes sense then, if the coolant is heated then the motor and oil should be warm enough for that initial startup and quick drivability. This thing is very complex and well packaged for every aspects that it takes to make it work. It is very interesting which is why I have all these questions.

Thank you for filling me in with this useful information, it is much appreciated!

I don’t see how people even used those things. I use it as an emergency only. Sounds like a ground to me in your building. Have a 40am charger installed and make sure it had a good ground.

This is new to us so we are using it for the time being as we normally leave it plugged in and the cable is just there when we get home. So its the same concept as a permanent charger just waaayy longer to charge lol.

The ground isn't the issue, I figured out what's been going on. These things draw quite a bit of power and my garage door opener is on the same outlet we use for the charger (i need to re-wire my garage since it's original from 1968) . Anyways when I open or close the garage door, it seems to trip the charger and stops charging.. I will eventually install permanent 40 amp unit and re-wire my garage.
