Sorry, I knew that. I was confusing topics (there's like 3 display topics I'm in right now).... my bad. I did try out subspeedo, worked good. When do you think you'll have support for other stuff like elithion.
what bluetooth adapter have you designed around?

Will be a couple of months, but I can push out test versions earlier. This month is a bit hectic especially at the end of the month so probably won't be till late Feb for a test release.

I will test on a bluetooth adapter but I havent decided what one for sure.

Let me know when you get ready to test. I've got a rooted android (Samsung Galaxy Player 5.0 and a Samsung Infuse) and can sideload APK's, and own a Lithiumate Pro. If you end up doing any canbus stuff, let me know as well. I've got a Curtis controller, and the Can spec and an OBDII-Bluetooth adapter.

Good idea to have single frontend capable of pooling all the various data streams into one gauge and logger.
It's about time.

You can greatly expand and hasten the adoption of your software by adding support for serial comm. from TBS E-Xpert Pro flow energy metering device (formely known as Xantrex Link10/LinkPro E-meter), which has been quite popular (defacto became THE standard) through the years, incl. this forum. The metering unit takes current/voltage from a shunt inside the EV's batt. pack, and then basically spits raw data divided by comma or something via its RS232 serial output (note: this port is not present on some models "Lite").

Obviously you get the ~same data upstream via controller, but allowing for more data inputs via such shunt like TBS Pro Meter will be specifically of importance for people with prototyping new batt. packs, or runing various parallel and addon batt. pack (think PHEV) etc.

So, apart from getting liveview display from the data stream, also adding data logger inside the Android machine, and providing some basic data manipulation/customization are the basic tasks, as usual these days. So, find someone in your area with this meter to help/team up in debugging..

Some related info here and older code available (and elsewhere): http://www.ohler.com/palm/EVDash.html

In the "latest" revision of the hardware sold as TBS they might have changed the pins in comparison to good old Xantrex, so it should be checked this serial route is still possible, shouldn't be necessary having their overpriced usb interface kit..

Two pages of good info on protocol and software for Xantrex Link/Pro:

Thanks for the info Mesuge

Xantrax protocol is straight forward but its not similar to any that I've implemented in the app so far so it will be a big chunk of work. Should b no problem using serial.

I'm reworking my logging, it was a bit adhoc before. Not sure how I will do it yet because I'm contemplating having a single log entry once per second with data from all sources instead of a separate log for each device. I need to be mindful that these phones/tablets dont have unlimited computing power.

Interesting thread

[evlowrider]

I have an update on this project and require some feedback....

Updates:
I have been making some great progress, my bluetooth connection code is looking good and I've implemented most of code for Zilla and Elithion Lithiumate data parsing.

Now the Zilla is simple because it uses the same gauges (graphics) that the Soliton1 code is using. So its mostly done now.

However I need to make new gauges for the Lithiumate since I do not have graphics for BMS type gauges.

I will be providing a hardware solution for connecting to USB/RS232 devices like Zilla and Litiumate. It will be provided as a DIY solution and a ready-made kit. More details on this later.

Feedback needed:
I'm looking for feedback on what data would you like/expect to see in the app from a BMS ? What info do you want to see and more importantly *how* do you want to see it.

Thanks

Pete.

What I'd use for my Elithion Lithiumate Pro
Gauges:
Pack voltage
Pack current
Average pack temp
Charge current
SOC
DOD

Indicator LED (on/off):
plugged in status
Contactor on
Ignition on
COM status

The following in an info screen:
Lowest cell voltage, highest cell voltage, highest cell temp, lowest cell temp, highest cell IR, lowest cell IR

The following in an info screen:
Faults

Maybe a user defined warning box, so they can chose a value, set high/low and set alarm color and have an alarm box in the corner. If there are multiple alarms, set it to toggle between them.

Now thats a good idea!

Yesterday I started adding a preference screen that is used to configure all settings of a gauge - expected min/max data values, angles for needle gauges, source for the graphics etc... So adding an alarm for each gauge will be quite simple.

I'm waiting on some hardware at the moment and I need to test that out before I can recommend it. Hoping to get a test release out to some people before the end of Febuary. Won't be a polished release - it will be to confirm that the Lithiumate and Zilla code is all good.

i am excited to see this app work with zilla, although i'm not finished my car, i would love to be able to monitor charging while i'm in my house or at a restaurant with the car plugged in. you might want to try speaking with Otmar about ways to get info from the hairball...and otmar was planning on adding features to the hairball...maybe you guys could talk about features that would benefit this app...it would be great if you didn't have to worry about gps for anything and just have the car telling you all the info

also will you ever adapt this app for iphone, windows phone, and black berry?
