Thomas,<div><br></div><div>Earlier this year, Matt Beard mentioned he was interested in doing i-Miev support, but I'm not sure of his status. He is on this list, so should see this. There are also several OVMS users who have that car in their stable, so the requirement is definitely there.</div>

<div><br></div><div>It is probably worth firstly doing a quick feasibility check, to see what level of OVMS support is possible:</div><div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div><div>

Firstly, What are the specs for the CAN bus? What baud rate is it, and what is the connector? There are  just three messages that are key to feasibility:</div></div><div><div><div><br></div></div></div></blockquote><div><div>

<div><ol><ol><li>SOC - battery state of charge - <i>car_SOC</i></li><li>Car On/Off (ignition switch, or Park/Drive gear lever) - <i>car_doors1 [bit7]</i></li><li>Car Charging (true or false) - <i>car_doors1 [bit 4]</i></li>

</ol></ol></div></div></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div><div><div><br></div></div></div><div><div><div>If those three are available, and readable by the OVMS hardware, then the project is most likely feasible. There are lots of other parameters (range, temperature, odometer, speed, vin, tpms, etc) that are nice to have, but are either optional (nice-to-have) or can generally be derived from these three key messages - so long as they can be found. For example, on the Volt/Ampera we don't know the detailed charge messages, but do know whether the car is charging or not - we can assume charge interrupted if the charge finishes before 95% complete. Similarly, if the range of the car is XXkm, we can estimate the current range based on XX * SOC%. If the car has no GPS details on the CAN bus, then we can use the GPS in the OVMS module itself.</div>

</div></div></blockquote><div><div><br></div><div>What vehicle two-character abbreviation do you think is suitable: IM or MI? Examples are RT (Renault Twizy), VA (Volt/Ampera), TR (Tesla Roadster).</div><div><br></div><div>

If you can let me have the can bus specs and information on the above 3 messages, I will create you a stub vehicle implementation.</div><div><br></div><div>Regards, Mark.</div><div><br></div><div>P.S. With reference to the development guide (<a href="https://raw.github.com/markwj/Open-Vehicle-Monitoring-System/master/docs/OVMS_Development.pdf" target="_blank">https://raw.github.com/markwj/Open-Vehicle-Monitoring-System/master/docs/OVMS_Development.pdf</a>), these are the current set of parameters that OVMS supports.</div>
