After nearly four years of driving a LEAF, I have finally got round to purchasing the LeafSpy Pro app for iOS. The app has gone up in price from £15 to £20, and with an OBDII wi-fi dongle at £13 from Amazon the total outlay comes to £33. There’s a lot of information to be gained from the onboard diagnostics and the app does a decent job of explaining it – given that the author has had to interpret the data flows himself. It’s not pretty, but it works. A recent upgrade even reports live tyre pressures on cars from 2015 onwards, which have TPMS. Saves all that messing around with gauges.
One reason I purchased the app is to keep an eye on battery condition. My second LEAF came to the end of its 2-year lease in October, and RCI Banque offered a reduced balloon payment that I couldn’t turn down – especially with four years’ interest-free credit. For some reason, even though the car is still the property of RCI, I feel more of a sense of ownership. Maybe it’s knowing that I shall have the challenge of selling it on one day.
The figure everyone looks at first is the battery health percentage. When I first looked at LeafSpy it reported 94% – not bad for two years and 31,000 miles, but hardly exceptional. Some people have reported that hard driving and rapid charging is, contrary to expectations, good for the battery; so on a recent run I took the charge down to 1% (another benefit of LeafSpy is being able to monitor the charge level right down to zero) and gave it a rapid charge to 85%. Hey presto, LeafSpy reported the battery health at 98% immediately and today it is showing 99%. It will be interesting to see if this still works when I come to sell the car!
