What charging speed are you getting on your Level 2 charger?

[FloridaSun]

Probably a long shot, but is your 240V AC charging current set to less than 'Maximum' through the in-car settings? I can't find anywhere in this thread where that was verified.

Mine is set to maximum..

Most residential is 220-240V. Most businesses have 208V and a small amount of residential also have 208V.

Single phase system voltage is 120/240 .
3 phase electrical system voltage is 120/208 (1.73*120)
There is no "220 V"
The max voltage drop should not exceed 5% from system connection to branch circuit utilization -2% service and 3% feeders and branch.
The voltage should not be less than 228V (really bad) if fed from 120/240 V system, and not less than 197.6V (equally as bad) from a 3 phase 120/208 V system.
If I see anywhere close to this with minimum load I am on the phone to utility supply right away.
Having the voltage too high can also be an issue (5% rule) which I have seen frequently when the demand goes down and the utility supply has not set their distribution transformer taps down yet , usually happens just after dinner which coincidentally when most light bulbs burn out.

From a North American perspective of course....

Of course. We do have quite a range in Canada - 120/240, 120/208, 277/480, 347/600, even more variants in delta 240/480 (rare) USA included
Mexico apparently does have 220/480.

I have a 24amp clipper creek charger plugged into a 30amp dryer outlet. Charges at about 5.5kwh

I'm not sure what's up with my EVSE. It seems to be charging faster than it should. My EVSE only has 2 amps more than yours and I'm charging at 6.0 to 6.1 kwh.

I wasn't aware of all those options. I grew up in Austria and we had 220 Volts and 380 volts if I recall correctly.. I actually studied Electrical Engineering but never worked in that field as I went into Programming.. It has been over 30 years ago and I don't recall all the details but I believe that the high voltage was 380 volts..

EDIT: 380 Volts, not 360 Volts..

What amp rating is your EVSE?

 

[electriceddy]

What amp rating is your EVSE?

Mine is 30A (7200 W ) Eaton EVSEL230HNAW . Had it since 2013, charged both my Leafs @6.6 kW , finally get full use out of it with the Kona (7200 W ) - I have good voltage about 40' from the transformer.

 

[electriceddy]

Didn't know that there was a difference..
I wonder what the actual dash readout indicates with those who have a 32 amp EVSE at home??
One thing that my setup has going for it is that it's likely running on very high efficiency as the outlet for my charger is right beside my breaker panel. The longer the distance to the panel, the more loss you will have.

Interestingly, it says "INPUT CURRENT 35A Max". I have charged on a 75 AMP juicebox before.. I hope that this is not an issue as I assume that the car would never draw at that rate anyways or am I wrong?

Your correct, the car will not draw more than its rated max regardless if you use an over rated EVSE.

I'm still pondering if I should upgrade my EVSE to 32 amps.. I have had zero issue with my 26 amp EVSE but on the other hand, 26 amp has been proven to be sufficient for my needs.

no, I had verified this some time ago, those settings are all at max

this is not entirely correct

people refer to 110/220 because historically in north america we've used 110, 115 and 117V. Today the nominal is 120.

the service supply is not guaranteed -2%.

for Hydro Quebec for example the 120V/240V can range from 106/212 to 127/254V
(document is unfortunately in french, you can see the numbers on page 12 and 13 http://www.hydroquebec.com/data/documents-donnees/pdf/caracteristiques-moyenne-basse-tension.pdf)

here's another document in english
https://www.pge.com/includes/docs/p...ergystatus/powerquality/voltage_tolerance.pdf

most of the time the voltage should be up to +/-5% but sometimes it can be up to +6/-13%. occasionally it can be outside this range for short durations.

so you could be -5% all the time and still be in the standard range. this is for the supply that comes to you from the power company. in other words your 228 is not "really bad", it's the lower end of what is considered the normal range.

CEC part 1 2018 24th edition (and this rule has NOT changed since previous editions)
Rule 8-102, Sub-rule (1) The voltage drop in an installation shall be based on the connected load of the feeder or branch circuit if known; otherwise it shall be based on 80% of the rating of the overload or overcurrent device protecting the branch circuit or feeder, and not exceed
(a) 3% in a feeder or branch circuit; and
(b) 5% from the supply side of the consumers service (or equivalent) to the point of utilization.

Those voltage differentials seem pretty extreme. I even get the better part of 108 V from a dodgy 14 gauge 100 + ft run to my outhouse. I can't really complain as its just for LED lights and I am my own utility(100% solar) at my farm
