I've not long got a new nissan E-NV200. In order to maximise range is it recommend or not to use drive mode B, where you get more regenerated power, along side Eco mode. I don't mind having the significant reduction in driving speed and acceleration.

Thanks

B will recover more energy when you take your foot off the accelerator at the expense of more of your speed. It is objectively more efficient to avoid slowing down and to preserve your momentum where possible. If you have to slow down then you're better off using regen than friction brakes. Better still is to avoid having accelerated in the first place.

In practice, using B with discretion only when slowing for junctions and roundabouts and sticking in D on the open road will save you a small amount of energy. However, with experience, you can learn to achieve identical efficiency in B and D by controlling the amount you ease off the accelerator.

Don't look at B mode as "maximise range", think of it as a convenience feature. If you are in D mode and take your foot off the accelerator, the momentum will carry you forward as you coast to a stop. If you do the same in B mode, the momentum carries you forward and also gets "consumed" by the battery, but the consumption process isn't 100% efficient, so you don't get back anywhere near as much as you've put out. But in B mode, if you still lightly press the accelerator, you can coast as far as in D mode, but with no regen. Having said that, I use B mode quite a lot in start/stop traffic, roundabouts, twisty roads, etc - basically anywhere that involves a lot of acceleration and braking, because I can do most of my control using just the accelerator pedal and only need to move to the brake to do a complete stop. Both modes are useful and have their place, but you can get the exact same range in either mode, so really use whichever you prefer the feel of and work on your technique. I view it more as a "coasting on/off" switch (which incidentally my old ICE VW had as well).

Very well described, thank you.

Hi! Anyone gathered data on realistic range kW/100km (e-NV200 40kW) driving avg/max 90/100km/h on highway normal vs ECO mode? Is it wortheless difference (1-2km)?

cheers!

No data but I have experienced the range indicator showing that getting to home looking a bit close to the wire. Switching to Eco about 30 miles to go and completing journey with charge in hand.
So I am conviced Eco does what it should.
But I do live in a very hilly area where it may be more effective.

Driving style will have the biggest effect IMO. All 'eco' mode can do is limit power, and probably make the cabin colder/hotter (depending on the weather). You can make all of those changes yourself. The motor will always be as efficient as it can be.

I just got back from 1000km trip (Milano, Italy-Split, Croatia). Tested everything. Driving on highway, D mode, eco and non eco mode, max speed (137km/h). Aprox 70-80km/h at highway is optimum (eco or non eco doesn't matter), thing is, it is just hard to drive that slow on highway. I drove 90-120km/h mostly, and was getting cca 140km (100 to 15%). I haven't used AC, so not sure how it impacts range. In the city it is amazing, i can get for sure 200km of range.

Anyone heard for these folks:

maybe one day add 33kW addon battery (instead spare tire) :)

tbh, i am in love with my e-NV200, tho it can be just as easily love in EVs in general, since this is my first EV :)

cheers all!

On my leaf the only thing eco mode is used for is reduced power when road conditions are icy
And even that is better served by swapping the heavy boots probably needed for walking n snow & ice for the lightest pair of shoes you can find !
