Re: How come D mode consumes more energy on a given load?

Tue Apr 19, 2016 4:12 pm

All we have amongst the three settings is simple gain changes when either applying power or regeneration. I have no documentation to back this up. Since you have CaniOn, as you pointed out, a time-consuming test would validate (or invalidate) this. After all these miles in the i-MiEV I have no suspicions that what I said isn't true.

Why would Mitsubishi build a DC-to-AC motor controller to react differently, especially when the car is always subject to being compliance-tested for power consumption accuracy ? That's another topic, as I don't think that Mitsubishi exploited the rules to their benefit as much as some of the other manufacturers did...

Sorry, but would like some hard data to back up such an assertion before going off on a wild goose chase.

Don't forget, we tend to use the 'real' brakes less when driving in B, and that alone could account for a difference. On any given trip there are simply too many uncontrolled variables, any one of which would distort the results - even an extra stop at a traffic light on an otherwise identical trip would produce a different result.

Hypermiling skills can dramatically alter the energy consumption on any given trip - that's the beauty of the i-MiEV: having these various settings we can play games and extend the range to whatever we need at the moment.
