Default Charging questions

Much to my delight, my sports club installed car chargers last fall.
When I first started using them, I would get about 10 miles of range per hour, which was significantly better than I had previously experienced at charge point or blink etc.

Recently however I am only getting 7 miles of range per hour.

Any ideas as to why this may be?

And secondary question, lately when in stealth mode, I seem to be using more miles to go the same routes I know well to the office or to the club.

Everything else is running as before, and I have no cel light or any other issues being signaled to me.

Any ideas?

Reduced charging can be caused by other EVs using nearby chargers.

Besides my beloved Karma, we now have a 2020 Model 3. On YouTube there are Tesla videos explaining how this phenomenon is occurring even at superchargers. The Tesla suggested solution is to charge during less popular times or to use a different charging location.

Also, reduced range in cold weather is normal.

Thanks for this reasonable answer.

There are two twin chargers and I always try to choose one that doesnít already have another car on it. I suppose that somebody can sneak in there after I leave the car, but have not noticed I yet. And I live in houston so although it is not summer here, it is also not that cold- it was 75 on the weekend.

There may not be an answer.

Do you think I will get any more info if I put the obd on?

Without a CEL, an OBD only reads permanent error codes. If there are permanent codes, look them up online and discuss with your service center.


With regard to charging, have you tried a different location such as in a shopping center? It might be an infrastructure issue with the two chargers at your club.

Turns out you must have been right....same charging station yesterday yielded 10 miles of range per hour. And the usage was back to normal today too as temperature was about 72

A/C usage, quick starts, seat heater turned on, stop and go,...etc

All factor effect range.

The Karmaís built-in charger can only use 1/2 of the available power provided by a Level II charger (3.3KW of 6.7KW). The impact of temperature is pretty minuscule, unlike the 100+KW DC charging power delivered by Tesla super chargers that require the battery to be in optimum thermal and SOC conditions to receive all that power. Add to that the wildly optimistic Range-O-Meter, and you can see why the range/charging estimate From the car is pretty much fiction.

In my personal experience, the Karma spends about (on average) about 500WH to travel each mile, so about 7 real miles per hour of charging is the best you can expect. I actually get a lot faster charging using the stationary charge and charge-on-the-run options of my TOM unit (9KWH and 14KWH, respectively), but thatís still peanuts compared to DC Combo charging or Tesla Supercharging.
