How I Use My Nissan LEAF's Trip Computer
The instantaneous mi/kWh metric is utterly useless. A 5 second rolling average would be far better. Also, a scale of 0-8 trivializes the major difference between 4 and 5 mi/kWh.
The "To 100% Charge" is usually wildly off. 6kW and 3.3kW recharge times would be far more useful. Considering Nissan says the 120V is "emergency charging," it makes no sense to show 240V and 120V times.
The power dots are cool, but I only use my Leaf from -4 (regen) to 3 dots. This leaves the upper 10 dots completely unused. I still like them though, not much to complain about there. On the center console screen, the pie chart thing is meh. It shows the same thing as the power dots, with few and far between data points. I'm a data freak, so I think it's cool to see when I'm using 18.5kW of power instead of "about 20kW" where the closest label is.
The temperature scale is also pretty useless. "It's neither too hot nor too cold" doesn't tell me a whole lot. I'd much rather see an exact temp, much like the GOM shows miles instead of just ±15% battery charge.
