After my previous attempt at a range record achieved 111 miles I was confident that I could beat it, so last week I had another go on my regular commuting route. This time I managed 122 miles (196km) on one charge. The approach was essentially the same as last time, so review that post for the details, except that I drove carefully and in Eco mode from the very start, and I had fully inflated the tyres beforehand.
I did, however, learn a few new things:
1. I knew this time the expected behaviour of the instruments, particularly the low charge indicators and the eventual complete loss of the range predictor, so I was more confident to keep driving even at a low battery state.
2. There is no ‘turtle’ mode that I could discern. Last time I thought the car was limited, though not consistently, to a maximum of 20mph. In fact I was confused; the limit came from the Speed Limiter value that I had set, and the reason I couldn’t set the speed to a lower value at the end, as I had hoped, is simply due to the Limiter having a minimum lowest speed setting of 20mph in all circumstances.
3. There is no easy way to determine the actual state of charge (SOC) left in the battery at any time. Therefore, towards the end, I stopped the car a number of times so that, on restarting, I could see the charge percentage indicator displayed. From this I could calculate how much further I could go (at least, until I checked it again). At the end the SOC was down to 2%.
4. The Total Consumption indicator is misleading. Although it displays a decimal point it only increments in whole numbers so you don’t know exactly what your consumption is (e.g. it jumps from displaying “20.0 kWh” to “21.0 kWh” with nothing in-between).
5. While driving my Eco score had been 97-98/100 but at the very end it jumped down to 0 (perhaps a hint that running out of charge is not considered to be good driving!).
Although this attempt had achieved a good range I am at a loss to see how I could improve it much further – particularly to something approaching the Spanish record. Therefore I probably won’t attempt it again until I have a better route to try it on, particularly one with fewer hills and junctions.
Nonetheless it was nice to get in the ZOE the next day after it had been recharged and be told the predicted range available was 116 miles.
