I downloaded the new EV ChAmp app a few days ago and used it for the first time last night.
It calculates the charging amperage necessary to have your car fully charged by the time you want to leave in the morning (or other time). You enter the start time and start range as well as the end time and range desired and it calculates the amperage necessary to have the car charged to your desired level by the specified time.
I entered a start time of 9pm (when my electric rates drop) and a starting range of 64 miles. It indicated I should set the charging amperage to 18 in order to have the car charged to a range of 180 miles by 8am. It's now 7:45 am and the car is charged to 179 miles. So it's incredibly accurate.
This is a great app and it enables something that many of us thought should be a built-feature. This app should be especially helpful when I want to do a full charge for a long trip but not let the battery sit fully charged for very long. In fact, I have a long trip tomorrow and will try it out. I'll set the desired range to 260 miles with a departure time of 9am.
