Hi,<div><br></div><div>Thanks for the offer, but I can do the mod here. I am more concerned that what gets released to other users is consistent with the other versions.</div><div><br></div><div>Matt</div><div><br><br>On Tuesday, September 24, 2013, Thomas Bergo wrote:<br>

<br><br></div>Regards to max charge rate "STANDARD xxA":<br>
The variable car_chargelimit should contain the maximum available mains current, which is set by the EVSE. <br>This is done in vehicle_thinkcity.c and I assume this can-message is available in a iMiEV and could replace the hardcoded "13A".</div>
<div><br>The evse sends a pilot signal controlling the charger max rate, which can be adjusted by the user in steps depending on the evse type.<br></div><div>The first evse's for iMiEV was delivered with two charging steps (maybe 10-16A) and got popular among Leaf-owners. Running up to 16A over the Schuko-connector is bad firesafety, so the later evse's were replaced with 13A. (I guess) limit max.<br>

<br></div><div>This setting is only for information in the app, as no information is send to the car from the car module. There is no way that the car module can impact on the charge current. The voltage and current (13A) is reported by the car and not limited by the OVMS.</div>
