<div style="word-wrap:break-word"><div><br></div>Thanks, Håkon - nice clear answer.<div><br></div><div>One other suggestion is that you can put "car_idealrange++; return TRUE;" and "car_estrange++; return TRUE;" in the poll0 and poll1 functions, near the top. A few STAT commands and you can see if the poll functions are actually being called. You can also put "car_idealrange=id; return TRUE;", etc, to get an idea of what IDs are being delivered. It is very nasty trying to debug interrupt handlers, but this approach can help.</div>

<br>Are you able to read any CAN-bus values from your iMiEV?<br>
<br></div>I experienced once at my Think City, that the Ovms-module did not read the CAN-bus at all; I got 0% SOC.<br>The problem was I had two external CAN-devices connected at the same time (Duinomite Mega + OVMS).

<br></div>Du you have access to any kind of can-reader tool?

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:0px 0px 0px 40px;border:medium none;padding:0px">
<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><br></div></blockquote><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>

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>
