I have a question. I'm new to the e-Up! and I was wondering what is Available power and e-max. Under e max there are 5 bars. The first 100km or so of driving the car all those bars were filled, but since I last charged it only 4 out of the 5 bars are filled. What does this affect? Does it affect the acceleration? How can I change it? It's been about 80km and it hasn't changed.
