Install a Remote Control in a 2011 i-Miev

Mon Nov 04, 2019 8:33 am

Hi

i have recently bought a 2011 i-Miev. The car doesn't have the remote control and I asked myself if it's possible to upgrade mine with the system. does that anybody know?

Greetings from Switzerland

Welcome to the forum! - Glad you found us :)

I doubt it would be easy - If the car didn't come with one, then very likely the receiver and the antenna aren't built into the car, so they would need to be added . . . . and hopefully, the factory wiring would be there to support them?? Lots of work for a marginal gain, IMO. We have two 2012's and we have the remotes for both of them, but we haven't touched either for several years. No doubt by now both would need new batteries

Good luck with the project, if you decide to give it a try - Document what it entails so maybe it will help someone else

The reason for wanting the remote (and receiver) is that models without them cannot pre-heat - eg it's impossible to run the heater while plugged in, even manually.

This is one of the things I dislike most about my 2011 Ion. In winter when there is ice to deal with I end up unplugging and turning the heater on manually about an hour before depature, blasting the heater for about 10-15 minutes then turning the car and heater back off again and plugging it in to top up the charge by the time I leave. Better than nothing, but certainly not ideal. It's either that or leave the house with less than a full charge, and I don't have the range for that.

Has anyone made any attempts to reverse engineer the pre-heating system by looking at the circuit diagrams and capturing CanBus dumps to see what commands are being sent to activate the heater and onboard charger simultaneously ? (Which are normally interlocked out)

Best case scenario is that the optional receiver ECU(s) simply plug into the CanBus and inject CanBus commands onto the network to command the onboard charger and heater to come on at the same time. If it's just messages onto the CanBus and we can reverse engineer them, then theoretically an OBD-II dongle could be used with appropriate software to operate the pre-heating system, potentially remotely if run on a 3G/4G connected tablet, (or maybe even a Raspberry Pi) and with much greater functionality than the original remote... (the OBD-II port has permanent 12 volts available)

I suspect that as well as CanBus data there may be a "wake up" control line to wake up the ECU's as normally the OBC and Heating ECU's would be asleep when the car is turned off and not charging, with no CanBus traffic. But that shouldn't be too hard to accommodate if it comes to it.

Any takers ? :twisted: I would dearly love to hack in some sort of pre-heating even if it means entering the car to manually activate it. Just activating the heater and onboard charger at the same time would not be quite enough because the heater power output would also need to be controlled to remain within the available power from the OBC depending on power source, since the OBC is limited to a maximum of about 3kW while the heater can draw up to 5.5kW.

So I assume the official pre-heating solution regulates the heater power consumption to avoid discharging the traction battery by keeping the power drawn equal to or less than what the OBC is putting out with the currently available power source.

Completely agree here, I've been reading countless forum threads on various sites (this one and speakev especially) and there doesn't seem to be any conclusive understanding of the CAN messages.

Most people seem to have either gone the petrol/diesel heater route or given up it seems.

There has got to be a way to figure out what the receiver unit is doing for the remote, but no one that I've seen so far has attempted to open up the box or capture its output. (Maybe I've missed something, but now in 2019 there has to be a way to do this, maybe drop in an arduino or something!)

I've so far attempted to run the heat on the charger (nope!), but also tried putting the car in ready and then plugging in charger... of course it immediately jumps back to ACC mode WITHOUT heat.

I've got an OVMS unit arriving anytime, so would be game to join in this effort to see if preheat can work. This car is super lovely, but would like to leave with fuller charge, especially on winter road trips.
