Ok guys, on Sunday night just gone, I charged the PHEV in the late evening and it was showing 36 miles range when fully charged. I had also been thinking about doing a long range test in ECO mode with the air fan in the off position; thought this was a good opportunity!
Only really started using the ECO mode the other day and also switched the air fan to "OFF", as it is usually showing 15 degrees, with one bar for the fan.
Anyway, to cut a long story short, I set off at about 11.30 p.m. from the West Midlands heading to the East Midlands in ECO Mode, together with the Mrs and the chihuahua; headlights on, radio on and all that jazz and managed to get a range of 39 miles before the engine had to fire up! I thought that was impressive.
Right! Now to the subject of battery care!
1. I never ever re-charge PHEV straight after returning from a long road journey or having been on the motorway, as the batteries may still be hot; I always try and re-charge batteries from a cool state.
2. Sometimes I leave PHEV batteries fully depleted overnight to give them a rest and charge the next day, or if PHEV not needed for a full day or so.
Following the above principles, I recently got a range showing 38 miles after a full charge the other day, which I captured with my phone camera!
Hope this helps!
Good Luck!
Happy PHEVing!
