Ford Focus Electric
by Tom Saxton 06 Feb '14

06 Feb '14

I've got a line on a scan gauge for a Ford Focus Electric and a vehicle I can plug it into. I should be able to read some interesting values: SOC as XY.Z%, energy to empty (kWh), battery average volts, battery average temperature, accessory battery volts, odometer, average battery charger input power (kW), charge time remaining. I'd like to capture the CAN traffic while reading the values for analysis later. What's the cheapest way to get data out of the CAN bus? Would this work? http://www.amazon.com/gp/product/B005FEGP7I/ref=ox_sc_sfl_title_1?ie=UTF8&p sc=1 Any suggestions on where to source an OBDII Y cable? Tom

i-MiEV support?
by lee colleton 05 Feb '14

05 Feb '14

I've seen that charging the i-MiEV is supported from other threads in the archive. What's the status of environmental control? I don't see the i-MiEV listed on the support page: http://openvehicles.com/vehiclesupport For my own part, I've damaged my remote and it's replacement cost is very high. I'd like to automate the process of charging and especially heating my car and have an OVMS unit on order. regards, --lee

Re: [Ovmsdev] Twizy45 testing needed

Hi all, Hi Michael, Listen, first things first: Wow, what a f*cki’n crazy great job you’ve done there !!! Now: well, works as expected on my Twizy45, Tried these on a very short run: POWER 120 115 110 (I believe I feel a slight difference, but not that obvious) SPEED 60 75 (didn’t have any slope to go beyond, got up to 60 neat and fast, kind of surprising/scary at first) RECUP 27 42 Ok, Recup: 27 instead of the default 21 (on the T45) is sensible, at the limit of slowing down a bit to fast for the following cars without a brake light 42 on brake is scary: you’re already at 27, once you barely touch the brake, 42% recuperation kicks in after half a second, so you get your expected friction-brake slowdown and boom, an extra slow down from recuperation… 42 is really too agressive, making an in between/modulated foot controlled slowdown nearly impossible… Will try 25 35 (Delta of 10% instead of 15%) We’ll see… Again: w00t! in town the crazy parisians will be less tempted to push me over the road as long as I can keep up with their illegal speeds ! (note: This is to be done at your own risk, mostly legal) (sorry for the lack of mail quote, I deactivated the digest mode which is kind of a pita) -- Julien (JaXX) Banchet

OVMS prevents manual charging, even from smartphone app
by Bennett Leeds 04 Feb '14

04 Feb '14

I had a power failure last night, so charging was interrupted.I went to the iOS app to charge, and it did, then stopped. Tried again. Went out to the car and saw that "Charging Stopped by Request." Sent a "ADD DISABLE 1" message, and than charging started fine. Shouldn't a charge initiated from the smartphone app happen no matter what? For a crude implementation,it could do a temporary ACC DISABLE until charge is complete and then reinstate ACC. thanks - Bennett

Ampera Range
by Paul Churchley 30 Jan '14

30 Jan '14

Just a bit of feedback regarding the range displayed on the phone app for the Ampera. A full charge currently displays a range of about 22 miles. This is probably a bit over half the real range and well below the estimated range on the car dash.

Hi Michael, With a bit of luck I’ll give it a run on my 45 later today/early in the week, gotta get my pickit back from my storage facility and give the car a charge :) Wasn’t able to compile it myself, linking the binary didn’t work out *bummer* probably screwed it up somewhere, so HUGE thanks for the zip, and Enormeous Thanks overall ! :) Mfg, JaXX —— ... Unfortunately, the Twizy45 owner who provided the data readout is currently unable to do the test. ... Regards, Michael -- Julien (JaXX) Banchet

Twizy45 testing needed
by Michael Balzer 26 Jan '14

26 Jan '14

SEVCON configuration support for the Twizy 45 is basically complete, but untested. Unfortunately, the Twizy45 owner who provided the data readout is currently unable to do the test. So, if there are T45 drivers here willing to test, please use the attached firmware build. To check the source, see: https://github.com/dexterbg/Open-Vehicle-Monitoring-System FYI: - max speed configurable is 78 kph - max torque is 36 Nm (default 32,5) - power levels of 130% should be possible, but watch temperatures The ZIP contains a script of test commands with expected results to check the basic operation before test driving. Regards, Michael -- Michael Balzer * Paradestr. 8 * D-42107 Wuppertal Fon 0202 / 272 2201 * Handy 0176 / 206 989 26

i-Miev/C-Zero/iOn
by Thomas Bergo 25 Jan '14

25 Jan '14

Hi As a owner of a i-Miev I'm interested in OVMS support for the i-Miev/C-Zero/iOn EV. Has anyone looked into supporting those EV? I'm planing to start looking into adding support for those EV. And asking for help to add a vehicle plug-in module stub for those cars, so that naming and so on is correct. Best regards Thomas B

Github Re-Organisation
by Mark Webb-Johnson 22 Jan '14

22 Jan '14

Github now has a 'Organisations' feature that seems better suited to what we are doing. Accordingly, I've created an organisation 'openvehicles', and migrated the four main repositories to that new organisation. The github URLs are now: https://github.com/openvehicles/Open-Vehicle-Monitoring-System https://github.com/openvehicles/Open-Vehicle-Android https://github.com/openvehicles/Open-Vehicle-iOS https://github.com/openvehicles/CAN-RE-Tool Looks much nicer, and the most important point is that organisations can have multiple owners. Supposedly the old 'markwj' repositories will continue to work (and be redirected). What is broken (probably) is the permissions system. I'm setting up teams for this now, and will send out invites to / add the previous users with write-access, to join those teams. I should be done today, and then it should be back working again. Regards, Mark. P.S. This is important, of course, in case I get run over by a bus. That said, if it happens I sure hope it is at least an electric bus ;-)

Motor temp does not support negative numbers (car_tmotor)
by Håkon Markussen 21 Jan '14

21 Jan '14

Hi (Mark). In ovms.h the motor temperature is defined as unsigned char (non-negative): extern unsigned char car_tmotor; // Tmotor Currently the weather is cold in Norway (-15 C) and I noticed that motor temp was 244C. Is it possible to update the car_tmotor to extern signed char car_tmotor; // Tmotor in ovms.h? Best regards Håkon
