I had to travel 75km one way and decided that this was an excellent opportunity to make a non scientific test of the range of my Think City.
The result was almost 147km from fully charged down to about 9%...
The theoretical range to full should be a little less than 160km, but no one should really drive to 0%... it is risky and you don't want to get stuck 700 meters from your destination - don't ask me how I know.
So along the way I took some photos from the nikometer screen as well as a photo of the dash showing how many km we have driven.
Then using this photos I created an excel sheet and used that to create a graph.
Here is the graph:
The thick blue line is the SOC as reported on the dash... there are two more SOC values based on different algorithms. The battery pack is using the 2 and combines them to come to a value that is presented to the driver. These 2 other values are presented by the brown and the grey thin lines.
And there is also the linear approximation line based off the thick blue one.
The wedge in the graph is when we reached our destination. Upon restart the SOC estimation algorithm had changed its mind... but as seen from the linear approximation this wedge did not represent significant change in driving distance.
Here is the raw data:
| km | SOC % | est 1 | est 2 |
|---|---|---|---|
| 0.0 | 99.2 | 99.2 | 99.6 |
| 39.2 | 76.0 | 73.2 | 73.2 |
| 47.4 | 71.6 | 68.9 | 68.9 |
| 64.3 | 62.0 | 57.2 | 57.2 |
| 75.1 | 55.6 | 50.0 | 50.0 |
| 75.2 | 50.0 | 49.2 | 49.2 |
| 93.0 | 38.8 | 39.2 | 39.6 |
| 111.7 | 28.8 | 30.0 | 30.0 |
| 133.1 | 15.2 | 18.0 | 16.8 |
| 139.2 | 11.2 | 15.2 | 13.2 |
| 145.6 | 8.8 | 12.4 | 10.0 |
And here are photos from the start and the end of the trip.
