Hello, I received a new Nissan LEAF SVE (equivalent to Tekna) in Ireland in April this year and for several months have been very happy with it. However, in September after ca. 7500 km (less than 5000 miles) the battery performance seemed to drop off significantly. Up to that point I had averaged between 1.4-1.5km per 1% of battery charge. Now I’m averaging only 1km per 1%. I still have 12 bars on the display despite an apparent drop in performance of over 30%. I travel the same round trip of 56km every day. This trip used to use max 40% of the battery, now it uses 55%. The board computer indicates that the energy efficiency hasn’t changed much since I got the car, still averaging 14-15kWh per 100km. This indicated to me that the battery appears to have lost capacity rather than any other external factor such as weather or driving conditions. I drive very conservatively, always in eco mode, never over 80km/h (50mph) and have used the rapid charger only 3 times in total, charging each time to 80%. Can anyone explain the reason for the apparent deterioration in battery performance? Why is the display still showing 12 bars? Can the telemetry in the car be trusted? Can I expect any satisfactory explanation from the Nissan dealer? Any information/advice appreciated. Thanks.
