Not true, in the Nordics we have 230V supply, charging still takes around 7 hours limited by onboard charger.
The cable is only a controller.
Surprising. Normally it takes about 3 1/2 hours on a 10A charger. Are you sure the cable box doesn't switch down to 6A because the outlet lacks sufficient power?

Hi,

How could I charge my PHEV quickly at home?
I understand that the charger that comes with the car can work in two modes depending on the current.
Is there a way I can install a power socket that will provide faster charging to the PHEV ?
How?

Alex

Install full 3 phase power and a DC fast charger at home. CHAdeMO will charge from empty to 12 bars in about 18-20 minutes (the car cuts off charging at 12/16 bars in DCFC mode). But it WILL kill your battery if you make a habit of doing it. I've only done it twice on my PHEV in about 6000 miles, both times in Santa Cruz because they have a free CHAdeMO charger.
Hasve you looked at the price of such a charger? At least 10.000 $. Not counting the adaptation of your electric supply system.

Yeah, I have. I think $30k-40k is a more reasonable estimate actually. I made it pretty clear that it's not practical, nor is it even recommended. But it IS by far the fastest way.

Now what I have in my garage is a NEMA 6-50 outlet and Charge point Home. That's a lot more practical. Many other EVSEs connect to NEMA 14-50.

16 amps charge station (only 14.5 consumed by car) should result in 3.5 hrs.
10 amps should result in 5.5 hours.
6 amps should result in even longer times.

Maybe the control box is designed to be able to detect a voltage drop when high current is consumed. I think / hope that when this happens the charger would switch off instead of step down, as it could indicate serious trouble.

If you look in the manual, Mitsubishi does not recommend frequently using DCFC, for the obvious reason that it'll kill the battery (although strangely they will allow the battery to DISCHARGE at over 30 kW in Normal mode for a sustained period of time which is just as bad or worse than CHARGING the darn thing at 18-20 kW).

I can confrim this is correct. My 2019 4HS will charge from 'flat' to 'full' in a little over 5.5 hours, at a little over 9.1A charge current.

I have monitored the current the charger consumes during the start-up phase and can confirm that a small load current is drawn for the first 30 seconds or so, around 2A (460W). It appears the system is looking at the actual voltage drop and calculating the maximum current it allows based upon this. On the two circuits I charge on at different houses, I have never seen 10A (9.1-9.2A is the most I've seen) and I suspect the charger is using a nominal 230VAC as it's reference point. i.e. it won't allow a voltage drop to below 230VAC which in effect will limit the charge current.

Yep, that's correct on consideration :oops: . I have a third-party one which is a nominal 10 A but when plugged into a 16A socket (nearly all of them over here) will obviously pull a bit higher current and be correspondingly faster.

I know the charging process ramps up slowly. That can be controlled by the control box but also by the OnBoardCharger. I am quit convinced the control box simply advertises 10 amps full stop. Maybe until to big of a voltage drop occurs and then it advertises 0.

Not from what I've witnessed. It will go from zero charge (0A) to about 2A (460W) instantly, stay at 2A for about 10-15 seconds, and then go straight to ~9A and stay there until charging is almost complete, after which it gradually reduces the charge rate from ~9A to 0A over a period of about 30 minutes.

Interestingly, even after a complete charge, the control box consumes about 2.4W for as long as the mains supply is connected and switched on. Although insignificant, it's something to bear in mind if you leave the car plugged in for extended periods of time - it'll cost you some extra money for no benefit.. :lol:

Thank you everyone for answering my question.
Here is what I've found:
My charging cable has 2 modes: 6A and 12A.
I was trying to change the mode when car was plugged and it did not work.
If I plug the cable and then press the Power button, it allows to change mode from 6A to 12A.
Problem solved.

I am thinking to get a Level 2 charger which is 30A to get a quicker charge at home.
Current cost is CAD 800 and $600 to install.
