[Ovmsdev] Leaf SOH

Wed Feb 6 04:30:09 HKT 2019

The SOH did come back the next time I started the car.  Thanks.

Is this with the car switched off?  Can you check with the the car ready
to drive?

Most other values we display are passively read whenever the can bus
is active, but to get more detailed values from the battery (v.b.soh,
xnl.v.b.hx, v.b.cac), we need to send an active poll request.  We don't
want to do this when the car is asleep, since it causes modules to wake
up and consume power.

We did previously get v.b.soh from a passive message 0x5b3, which is a
7-bit value (0--100%) available whenever the car is awake.  The active
poll to 0x7bb.6101 gives better resolution (~11 bits).

We had a similar situation with the SOC, where I think we have a better
solution.  We now report both low- and high-resolution values as separate
LEAF-specific metrics: the simple percentage in xnl.v.b.soc.instrument
and the high-resolution value scaled as a proportion of the "new car"
value as xnl.v.b.soc.newcar.  By default, the standard metric v.b.soc
reports the value from xnl.v.b.soc.instrument; there is a config option
if you want it to report xnl.v.b.soc.newcar instead.

I think it would be better if we followed the same pattern with SOH.

This is implemented in:

https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/200

Report SOH from passive 0x5b3 in private metric "xnl.v.b.soh.instrument".
Report SOH from active 0x7bb.6101 in private metric "xnl.v.b.soh.newcar".
Standard metric "v.b.soh" copies from "xnl.v.b.soh.instrument" by default,
or from "xnl.v.b.soh.newcar" if config option "xnl.soh.newcar" is set to "true".

Hello Mark

I have a Fiat 500e and asked if there is anybody who is firm with the CAN Id?s.

In the meantime I have some CAN informations for Fiat 500e  and can give to you or somebody who is familiar to programm the OVMS for this car.
I don?t have enough experiance to programm this. Sorry!

What informations to you need to insert this car to your project ?

I?ve had a user in Australia contact me about this recently. It seems there is some activity on Fiat forums, with people discussing this? I am told the factory app is non-renewable after 3 years, and many cars are being exported out of USA.

This user is a Fiat and Alfa technician, so has quite some knowledge of the cars.

Regards, Mark.

  I had trouble with the Arduinos I'd gotten, they seemed to garble the 2nd CAN whenever the baud rate was set correctly. I only got a single day to play with it before the telematics was cut off on our roomates 2014 :( 

  Another local friend just got a 2015, don't know if his telematics work or not though.

    (Maybe perkins.jason)
    I have also some sniffing done and send you file for arduino. This works for SOC.

    Maybe we can share information?
