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[]) {

Server Authentication Confusion
by Douglas Urner 30 Dec '22

30 Dec '22

We’re trying to set up an OVMS server and I’m puzzled by the authentication process. After (making an attempt at) following the server setup instructions (https://docs.openvehicles.com/en/stable/server/index.html <https://docs.openvehicles.com/en/stable/server/index.html>) we’re seeing these message after starting the server: 2022-12-30 00:18:03.533595 +0000 info OVMS::Server::AuthDrupal: - - - Periodic Drupal maintenance DBD::mysql::db do failed: Table 'openvehicles.users' doesn't exist at plugins/system/OVMS/Server/DbDBI.pm line 181. After a bit more poking, it appears that the only functional authentication module wants to talk to a Drupal site (presumably to populate the users table). Do we need to set up a Drupal instance, or is it possible manually populate the openvehicles.users table? Thanks, Doug — Douglas Urner (he/they) | dlu(a)canishe.com | +1 360.769.5565

OpenChargeMap read failed
by Greg D. 30 Dec '22

30 Dec '22

Just noticed this; not sure when it started. I open the OVMS app on my Android phone, and see a diagnostic pop-up that goes away in a few seconds, so hard to read the whole thing, but it repeatedly shows every so often. It starts OpenChargeMap read failed: https://api.openchargemap.io/v2/poi/?output=json&verbose=false&latitude=... with my lat / lon and more stuff after that. Something need a thwacking? The car is a 2010 Tesla Roadster 2.0. The OVMS is connected via WiFi to the home network, and the displayed data seems to be valid. Greg

Slider widget not disabled when first loading unchecked?
by Michael Geddes 27 Dec '22

27 Dec '22

Hi all, I've noticed that if you create a 'slider' widget with a checkbox that if it's unchecked when it first loads, then the slider is enabled. If you check/uncheck then the slider is disabled. Or at least that's what I seen in google chrome. I'm really not familiar with NodeJS, but this _seems_ to fix the problem: Does this fix make sense? If so - I'll do a p/r for it. //.ichael * Slider widget plugin */ $.fn.slider = function(options) { return this.each(function() { - var $sld = $(this).closest('.slider'), data = $.extend({ checked: true }, $sld.data()); + var $sld = $(this).closest('.slider'), $cbi = $sld.find('.slider-enable'), data = $.extend({ checked: $cbi.prop("checked") }, $sld.data()); var opts = (typeof options == "object") ? options : data; // init? if ($sld.children().length == 0) { var id = $sld.attr('id'); $sld.html('\

SPIRAM memory test fail
by Patrick Stein 24 Dec '22

24 Dec '22

Dear all, I’m having a weird problem. As I’m not courageous enough to keep the module connected all time, I will connect the module when starting the vehicle. For some reason however the module always had to be reconnected cause otherwise the blue light would stay continous and unresponsive ( no wfi ). Today I went into the underground garage with my laptop and connected the usb cable (not connected via obd) and immediately then connect Terminal.app. And I saw the following: > E (2061) spiram: SPI SRAM memory test fail. 131071/131072 writes failed, first @ 3F800000 > > E (2061) cpu_start: External RAM failed memory test! > abort() was called at PC 0x400818ea on core 0 > > ELF file SHA256: f4a716b153577bae > > Backtrace: 0x4008ddd2:0x3ffe3c10 0x4008e06d:0x3ffe3c30 0x400818ea:0x3ffe3c50 0x400792bc:0x3ffe3c90 0x4007969d:0x3ffe3cc0 0x40080721:0x3ffe3df0 0x40007c15:0x3ffe3eb0 0x4000073d:0x3ffe3f20 > The version is a modified one as I added a battery voltage check to the code that uses a calibrated voltage. I don’t think the error it’s related to the code. After pressing reset the system boots normally. Interesting enough it only happens after a night’s reset without beeing connected to the car. When I try it after it has worked it will always boot up fine. I’ve never encountered that error on my desk. Is the new module maybe broken ? Regards Patrick

New Metric Units
by Michael Geddes 14 Dec '22

14 Dec '22

Hi all, Some of the code I copied from Kona/Kia code had both kwh/100km and km/kwh metrics in the code as 'Other'. Adding the various power consumption Units is not particularly hard (I will have a pull-request soon) - though the conversions between them all required some thought! ... but it also made me think these two metrics that are (with the consumption units added) defined like this: m_v_trip_consumption1 = MyMetrics.InitFloat("xiq.v.trip.consumption.KWh/100km", 10, 0, kWHP100K); m_v_trip_consumption2 = MyMetrics.InitFloat("xiq.v.trip.consumption.km/kWh", 10, 0, kPkWH); These are effectively the same metric but in different units! I'm wondering if we would be better to have scripting and Duktape support for converting metrics to different unit! This might be also quite useful for those strange countries that insist on using miles as a measurement. On top of the 'metric list' and 'metric set' we could add a 'metric get' which gets a single value.. and add unit support for get/set. I've also got a pull request that improves the precision of the km<->mi conversions and factors it out. //.ichael
