Poll, do you use Google Maps to get max EV range?

Ok, I started writing a reply with an idea of how to estimate the range penalty associated with a certain grade, but it got a bit out of control so I've posted it in a new thread here:

How about using Torque and log the KW from ICE and HV battery?

 

Torque is a GPS data logger and you can log any of the sensors along with the gps data.

 

I tried to do this with torque. When you average out those instantaneous mpg averages it wasn't anywhere close to my real mpg. Problem odd the distance traveled using zero gas-that torque still assigns that a fuel usage value

 

I would use kwh (gas and electric) used per road segment (per mile or km). I think one of the monitors (PID) is for KW from the ICE and another from the HV Battery.

 

the best approach is going to be to pull a PID that shows the volume of fuel used over a specific period - either distance or time. That way you can say precisely 0.0025 gallons were used over the last 1/4 mile (or whatever). I'm not sure there's a PID that does this, at least not for the GEN III that i've found yet.

 

A friend just sent me this link. You can put it your start and stop address and it will calculate your expected EV consumption.

I just tried my daily route from the previous post and it was spot on.

PS, the Volt is known as an Opel Ampera in Europe.

 

I keep forgetting this is in the PIP subforum, but it's something that would benefit all prius owners and the approach would be relatively similar whether EV or ICE.

I have access to decent software that can create a network based on real-world energy use data. I had a free weekend not long ago where I sat down and tried to implement. It was incredibly time consuming to build even a basic two-choice network (i.e. two ways to get to a destination - one over a hill and the other longer but flatter). In the end I gave up because it wasn't worth the time investment when I could just drive my car each way a few times and figure out which was more fuel efficient.

If the intent of this thread is to build (or talk about building) a model that would work universally around the country or world or whatever, that's not something that you or I or even 1,000 of us is going to accomplish soon, and it's not going to be very accurate. At least that's what I'm thinking right now.

I don't even think Google could accomplish this with much reliability because they don't have access to OBD fuel energy consumption data. It's really going to require a large investment by the automakers to pull this off. The good news is that once you have the energy consumption data/model created, the rest is easy. This is the future.
