Firmware release 3.3.003 to MAIN / 3.3.004 preparation
by Michael Balzer 16 Jan '23

16 Jan '23

We missed releasing 3.3.003 to /main. It's been in /eap since 09/22, /main still has 3.3.002 (since 03/22). Mark, would you please go ahead on this with api.openvehicles.com? I'll follow with ovms.dexters-web.de. Regarding 3.3.004: Thanks to all contributors we have three new vehicles in the queue: - Renault Zoe Phase 2 initial support by Carsten Schmiemann → https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/732 - Hyundai Ioniq 5 initial support by Michael Geddes → https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/762 - Mini Cooper SE initial support by Vincent Barat → https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/789 Michael Geddes has also done a lot of great work on implementing full user metrics unit support at the module. This already works very well and stable in the shell, and the web UI extension now is also ready for inclusion (Michael, unless you've got some open todo I missed?) → https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/795 To get the new vehicle support into /main ASAP, I suggest heading for the 3.3.004 release now, including Michael's user unit support. Please report any open issues that need to be addressed for the 3.3.004 release. Thanks & regards Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 833 5735 * Handy 0176 / 206 989 26

Coulomb metrics !?
by Michael Geddes 09 Jan '23

09 Jan '23

Hi all, I've just found the total power used/recovered metrics (after realising in the I5 code that I was retrieving but not updating the appropriate metrics). Anyway, I then noticed the following: v.b.coulomb.used v.b.coulomb.used.total v.b.coulomb.recd v.b.coulomb.recd.total The weird thing is that these are all in Amp Hours, which is not coulombs (coulombs is "amp seconds"). I'm going to submit a patch-request that adds kC (kilocoulombs) since that keeps the numbers reasonable, as well as megajoules (related to kwh) I was wondering whether it's worth having the above values stored as 'kilocoulombs' rather than 'Amp Hours'!? But I realise that this would have potentially bad affects as the raw metric values available on servers etc would change. *sigh* Is there anything that can be done? //.ichael

Replacement ovms!
by Michael Geddes 08 Jan '23

08 Jan '23

So I've had this issue with the HUD not powering up when connected to the OVMS and then I just had an issue with a bad file in /store causing continuous reboots and thought I'd get a replacement base unit. I already got a small refund from the old distributor because of the faulty hud power. The problem is that the shipping cost is stupid expensive. US $180 for base module (no GSM) then $205 for shipping!.. =AUD $560 from medlock. Going for the UK site I have to get it as a kit with cables, but at £166.93 + £19.97 shipping... Which at AUD $328 is a lot cheaper... What the actual f? And I get 2 antennas I don't need and a SIM I can't use as well as the GSM module that I was going to either transfer over or get an in-car wifi solution. What on earth is going on!? Michael

Is Car (CAN / OBD) Data Visible Without A Server Connection?
by Douglas Urner 01 Jan '23

01 Jan '23

I’ve started experimenting with our Kia Niro EV (2022). I'm connecing to the OVMS module via wifi and a web browser, and don’t have a server connection yet. The only data that I’m seeing from the module appears to be module state (12V battery voltage, wifi state, modem state, etc.). I’m not seeing any of the “car” data like battery voltage or SOC. Should I be seeing any of the car state at this point? Thanks, Doug — Douglas Urner (he/they) | dlu(a)canishe.com | +1 360.769.5565

Remaining Charge calculator
by Michael Geddes 01 Jan '23

01 Jan '23

Hi, There's a remaining charge calculator currently in the hyundai base class which I have improved upon. This configuration allows for the charge voltage to be part of the equation. This is the example from data I collected with the ioniq 5 on 800v charging .. and I've written a plugin so I can get more charge profile information at other charge voltages. I'm happy to leave it in the Ioniq 5 code, but was wondering if I should put the implementation in a common area.. vehicle.h maybe? //.ichael ---8<---------------------- // Charging profile // - Must be from lowest to highest to%. // - Higher voltages must come before lower voltages for the same to% charging_step_t ioniq5_chargesteps[] = { // voltage, to%, WattHours { 750, 10, 100000 }, { 750, 25, 190000 }, { 750, 45, 220000 }, { 750, 75, 120000 }, { 750, 80, 80000 }, { 400, 85, 60000 }, { 400, 90, 40000 }, { 100, 90, 1100 }, { 400, 95, 25000 }, { 100, 95, 7400 }, { 100, 100, 7200 }, { 0, 0, 0 }, }; int CalcRemainingChargeMins(int chargeVolt, float chargespeed, int fromSoc, int toSoc, int batterySize, charging_step_t charge_steps[]) {
