    I have found in the winter that it underestimates usage. For me a general rule has been that if it is 32f I would estimate 20f cooler and you will get very close to actual usage. Better to be conservative on winter travel. Other than that I love the evtripplanner. The on board planner gets better all the time, but I always use evtripplanner before every long trip.

    I've found that EVTP does some weird routing sometimes, and you have to check the path to make sure it makes sense. Such as: from my place in Western Colorado to Seattle, it had me go through Montana ...in the winter?! Not to mention that was a couple of hundred miles longer. Easy to fix, though, by putting in intermediate cities you want to be sure to go through.

    So sure: I use EVTP for planning. And I use the car's nav to execute that plan.

    Just a quick note on EVTripping, it uses actual weather (current weather if no planned trip depature time or past or future weather) for the trips. It also takes elevation changes into account, traffic, etc.

    For EV trip planner, how does one get the proper wind data to enter into the system? That's one factor I have no idea how to input.

    As well, the payload, and speed factor (increasing from 1.0 to 1.1) don't seem to make much of a difference with energy useage. I can't understand that.

    Payload does not make much difference however the speed factor makes a big difference. I just plotted a trip to PDX and at SF1 it comes back with 356Whrs/mi at 66 mph. Increase SF to 1.1 and it comes back with 389 Whrs/mi at 73 mph.

    Here's another site for wind forecasts: Windfinder - wind, wave & weather reports, forecasts & statistics worldwide

    Payload isn't worth bothering with, but speed factor does make a difference.
