For some reason the last few weeks my car only charges to 35 miles total. It stops there no matter how long I leave it charging.

I have the installed Caddy charger at my home and I live in CA and the temp has been warm and nice. At one point It was charging up to 42 miles, now no more than 35.

What's going on? Anyone have any ideas?

Basically, aggressive driving. the charging distance is directly related to the most recent battery consumption versus miles traveled. Some examples I was able to test, used the adaptive cruise control extensively. Started morning off with 42 miles charge. Drove to work, 33 miles, down hill at 75MPH. charged back to full charge. now charged to 40 miles. Returned to home on reciprocal path. Charged to full. In morning showed 38 miles. Then drove to work and home same route, same distance, same weather, but this time at 55MPH. The miles when leaving work was 43, and then the following morning it was 45. I continue to get the same results. More efficient driving and the car shows it can go farther on charge, less efficient driving and you get shorter distances.

I usually have my charge hover between 41 and 45 during the week. On the weekend when I do shorter more leisurely drives, my distance has been as high as 49 miles.

Ok but my full charge is only showing 35 miles now and I haven't been driving overly aggressively. This is very frustrating.

I don't understand why it wouldn't charge to at least the stated 37 miles. I feel something is wrong.

Do monitor your stats? Are you on Voltstats.net? both will provide you with feedback on your usage. The miles is a reflection of what the car believes it can cover in distance based on recent recorded usage. charge level is measured in kW. look at your charge info screen you get in and see if shows a full charge. make sure you are not in L when driving and do not do any aggressive driving. There are many considerations when trying to increase the range. Is there a lot of up\down hill driving? Has it been very cold? Are you driving in L a lot? etc.....

I am not on Voltstats but I will check it out. I appreciate your suggestions btw. To answer some of ur questions, I never drive in L, there are not a lot of hills around me and the temp has been warm and nice, we are in SoCal.

Nothing has changed. I've had the car for 9 months now driving the same way around the same areas and now it's only charging up to 35mi on a full charge. And I know it's not my charger because I have charged it at various places and always the same thing 35max.

Just don't get why it wouldn't charge up like before? Could something be wrong with charge system or battery?

Is anyone else experiencing this issue that when you charge it completely and it shows complete charge and only shows 35mile range?

The available miles your car shows is a guess, not an infallible statistic. What's is important is the actual range you're getting. The EV range my ELR shows when I turn on the car after a full charge can be as low as 32 miles or as high as 45 miles depending on how I've been driving, the temperatures in my area, and whether I charged from empty or half-charged. But regardless of the car's guess, on my regular commute, I almost always get 36-38 EV miles per charge without fail.

Also, usage. Things like is the AC off, ECO, MAX, set at 68 or 78?, are you using the heated seats? both or one? on high or low? etc. Anything that consumes power will affect distance.

To dovetail onto Blast post, I usually cover the 33 miles using about 8kw to, and 9kw back. Always at 75MPH. I should drive slower but you know....

I did a little experiment with my ELR using ECO one week and Max (comfort) the next week with the thermostat set at 72 degrees. Driving the same distance with fairly constant temperatures both weeks the "available" charge miles was 32 to 35 miles when using MAX and 40 to 42 miles using ECO. I also ran the battery down to zero in each HVAC setting and got actual EV miles of 39 in MAX and 47 in ECO. In other words the miles after charge is an estimate and shouldn't be taken too seriously.
