OVMS for Mitsubishi i-Miev, Citroen C-Zero and Peugeot iOn

[PV1]

So, I just got this notice from PTel. Looks like I need to find a new SIM card. Anybody have any suggestions?

Dear PTel Customer,

We regret to inform you that after 15 long years, our journey has come to an end. We will discontinue offering wireless services at the end of January 2016. We do advise you to port out your number to a new provider. We will still be here to assist you in your move. We have negotiated some offers with excellent providers using the same network so you can still use your existing phone and keep the same coverage. We have offers for you below. Please check our website regularly (ptel.com) for any updated information or offers.

Straight Talk, $500 a year (bought up front) can get them at Walmart. Mine runs on ATT and is great, no issues.

I was reading on the Tesla forum that the OVMS has the capability to stop charge at either a desired range or a SOC. Have you or anyone else tried to get the i-MiEV to stop charge at 80%, for example?

I gather daily readings of usage, distance, HVAC usage, etc. Currently, the best (most accurate) way to gather daily usage info is to allow the car to fully charge everyday, so that ending SoC is the same. I would like the capability to automatically stop charge at a lower SoC, say 85-90% to extend the life of my battery.

Here's the page on the Tesla forum:

was there an answer to PV1's question about OVMS ability to stop charge at a selectable SOC % ?

I wonder what would be required to bribe the devs into adding pre-heating and charger control. Although I'm not sure that the Mitsu has charger control from the can bus.

i was wondering about that today also, then looked it up on the schematic--indeed the on-board charger is on the CAN2 buss.

i want to figure out the CAN commands to turn on the defroster while plugged in to the EVSE. The remote obviously sends a signal that tells the car to do this, so it should be possible.

Here is how I did this for home use (not remote use) with a Intermatic CA3750 Z-wave device, and a VeraLite Home Controller, and a BeagleBone Black Single Board Computer.

I purchased a Intermatic CA3750 to shut off my electric car charger when the charge reaches a certain percentage (like 80%). Many thanks to the previous reviewers of the Intermatic CA3750 on Amazon.com for clarifying how to wire this unit up for electric water heaters; the wiring is the same for an electric car EVSE. I simply wrote a Python program to read the charging status and state of charge percentage from the OpenVehicles.com server. So when the car is charging the Python program watches to see when the car is charging and when the state of charge reaches say 80%; it then sends a Http request to my VeraLite Home Controller which sends a Z-wave signal to the CA3750 and shuts off the power to the car charging unit. The python program runs on a BeagleBone Black Single Board Computer Development Board I had laying around doing nothing. This set up works really nice and I already had all the parts except for the Intermatic CA3750. Plus I learned Python in a very short time and love its ease of use.

Very cool. Glad someone was able to make something like this work.

As for my SIM card, I switched to Ting, which has pretty reasonable rates (no traditional plans, just tiered rates for separate items such as data and messages). Plus, because I switched from PTel, I got a $75 credit on my account, which should last for 3-4 months.

With this setup there is also a safety factor built into the OpenEVSE I am using since it it set to only charge between the hours of 00:05 through 07:30. So I don't have to worry about the Intermatic CA3750 coming back on unexpectedly and charging the car more. If I want to charge during the day I just push the OpenEVSE button to charge now and the Python program will still shut it off at 80%.

Yes, I switched to Ting as well. However I did file a complaint against PTEL with the FTC and the state attorney generals office since I still had air time with PTEL which could not be used and will not be refunded. I won't do any good but at least it felt good to complain about it.

I've discovered that the OVMS uses very little data, I see usage logs of 8-15kB, and apparently it's being rounded to 0 on the billing system.

I'm using a Simyo prepaid sim, and apart from 2 SMS messages for 10 cents each, I still have 22,30 euro left. The data is billed by the kB for 15 euro cents per MB. So far, just 20 cents has been deducted after a week of use.

Jjlink, PTel was offering refunds on remaining account balances, but it was case-by-case. I'm not sure what happened to them, but they could've been a little more graceful on closing the company.

I had $77 left on my account, but didn't find out about the refund availability until it was too late. At least I got a $75 credit with Ting, so that pretty much made up for it. Something happened to my in-app notifications, so I've been using SMS, and that took care of some of the balance I was building up (no cost incurred with data usage). A side benefit is that I know exactly when my car finishes charging at night (I turn data off on my phone when not using it to save battery, so any in-app notifications come in with the time stamp that the phone gets them (which is when I turn data on in the morning).

Not sure yet if this affects Ting, but yet another hurdle for us OVMS users on AT&T or one of their MVNOs:

So much for the flip phone I just bought two months ago to replace my Droid Turbo.

**UPDATE**
It doesn't appear that T-Mobile's GSM network is going away, so Ting and other T-Mobile MVNOs should keep working.

A CNET representative confirmed that the 2G network would not go away.

Hadn't been on this forum for a while, but wanted to point out that I've been using a FreedomPop Global SIM card for the past few months in my OVMS unit with no problems. It's a data only SIM card, so it won't send or receive SMS texts, but for getting the charge status, location, etc it works great. Best of all, the SIM is at most $10 to buy (usually on sale from $1-5), and has no further fees for the free 200MB/month level of service. Just be sure to CAREFULLY remove all of the "premium" features that are automatically turned on when you sign up for FreedomPop. It would be best to search online for detailed instructions on how to do this. Once you have it set up though, you never need to worry about paying for anything, you just get to check your charge status from anywhere.

If you already have a SIM in your OVMS unit, just reconfigure the APN to the FreedomPop settings, then drop in the new SIM. If you don't have your OVMS currently working, though, you may have to borrow a SIM, or else get a cheap H2O or other SIM just to do the initial setup.

EDIT:
Actually, just after posting this I saw they're offering SIMs for $0.99 right now (with a free powerbank and selfie stick...) https://www.freedompop.com/offer/labordaysim . Might pick up a third for myself. Why not?

i've searched all over the OVMS site and github, but can't seem to find the imiev specific source code for the OVMS--something like vehicle_imiev.c and .h maybe? Does anyone have the source or can direct me to it, i would like to take a look at which CAN ids are being used, etc.

 

[PV1]

There's an experimental build you download that has vehicles in development, including the i-MiEV. Switching between vehicles is handled by a parameter in the settings, specifically MI for us.

Managed to find this:

Thank you that's what i was looking for, just couldn't seem to find it...

I have been using OVMS Firmware version: 2.6.2/MI/V2 from Jan 18, 2014 for some time. Is anyone using a newer version?

 

[PV1]

There's firmware 2.8.5 out there, but it doesn't show any MiEV specific changes.

I'm still running 2.6.5. The only issue I have is that app notifications stopped working.

 

[jjlink]

Ok, I will stay on the Firmware I currently have. Thanks

 

[PV1]

Does anybody else that uses OVMS have issues with notifications? At first, they stopped working on my Android apps but continued working on iOS. Now, both apps and text notifications no longer work.
