I recently bought a second hand 2012 Twizy, with around 9.000 kms on the clock. It is quite the funkiest little car to drive.
But I have got the impression its range is less than the new Twizy I tested prior to buying my unit.
For the test, I drove the brand new test-unit from the dealer to my house and back. The Renault dealer is on the same road as my job, just 8 km further. It was a total of 60,5 km and I had 4 km left of expected range.
My commute is just 45 km on that same road so I was expecting to get back home with at least 10km of expected range left, if not more. That is not always the case.
Since I lease the battery from Overlease, I demanded a free test to check its status. I got an appointment at an official Renault Z.E. dealer nearby. They told me the test to check the degradation of the battery would take almost a full day. But after I left the car, they called me in 30 minutes to pick it up. They told me the test was done and it was at 100% capacity. I tried to explain to them that is hardly possible, since the car was from 2012. I found out they just plugged the car to a computer and the item regarding the battery only showed two values, total capacity=100% and current capacity=46% (meaning the battery was currently half charged).
I called Renault customer support and they were not certainly of any help. They seemed not to have a clue about how to perform such check to the battery. I called Overlease and explained the issue. I’m pretty sure the test performed to my car was not the proper one to determine the degradation of the battery.
They just took note and told me they would forward my question to tech support, and let me know whether I should take the Twizy back to the dealer or take it somewhere else for the test I want to perform.
It just seems to me weird not even Overlease is sure about the degradation test. Hasn’t anybody done it yet in Spain? What is the test like? Do they upgrade the firmware or anything like that i should be concerned about during this procedure?
