OVMS v3 wrong estimated range

Message status from OVMS v3 with e-Niro, now gives wrong estimated range:

Not charging
SOC: 56.0%
Ideal range: 237km
Est. range: 10924km
ODO: 16772.0km
CAC: 89.6Ah
SOH: 100%

(Estimated range can't be high as 10,924 kms being at 56%...)

Also while getting this message, the car has charging, might be related to
https://www.openvehicles.com/node/2331 ?
However by going to the website ( https://dexters-web.de ) there says that is charging (but still, extremly high estimated range)

Estimate range

The range is calculated from the 20 last trips. I think it will be better over time. Otherwise post here again.

it's random

Hi Timo,

We'll I've done those 20 trips after the EDGE upgrade (Oct-14).
Today was giving an estimation even crazy/higher (181622 kms!):

OVMS# stat
Not charging
SOC: 90.5%
Ideal range: 362km
Est. range: 181622km
ODO: 16949.0km
CAC: 144.8Ah
SOH: 100%

So after your comment, make me think, and I've tried one simple thing that I didn't: Reboot.
After the reboot I'm getting a quite more reasonable estimation:

OVMS# stat
Not charging
SOC: 90.5%
Ideal range: 370km
Est. range: 412km
CAC: 144.8Ah
SOH: 100%

I'll follow on the coming days to see how evolves... but really looks like this reboot in between those two readings helped ;)

Thanks!

Estimate range

Sound like a variable that was not initialized. I will check if I can find something in the code.
