In the graph below your car is roughly marked with the purple cross.

Thanks - results as expected.

What reporting frequency is useful for your project so I can contribute in the future?

And 2 more from Spain.
Also one more from Canary Islands.

Only have this.

Javi - Can you explain this comment or provide a link where we can see more information.
I'm guessing this is about battery replacements, but the image you post shows 89.8% SOH which is no way near the 70% required for a replacement.

Here's an unusual DIY fix for a degraded battery.
Put a replacement 60kWh battery from a wrecked B olt EV into the boot.

The country with the best climate for the Soul EV seems to be France.
4 of the top 10 ten cars with least battery degradation are in France.
Look here and be impressed - Forum • SOH de nos Soul EV dans le temps et les km (à épingler)

Seen below the GOM of a July 2015 27kWh Soul EV after 107,427km

The deterioration stats include -
Teirhy - 60,000 km - 101.3% SOH
Gepeliste - 107,427 km - 94.5% SOH
CedSoul - 62,000 km - 100.7% SOH

All 3 of these will not reach the warranty limit until after 275,000km.

Found this thread via google and have studied some of your results. I'm a bit confused about the cumulate energy charged/discharged (CED/CEC) counters reported by Torque.

Shouldn't these numbers agree with the trip computer results reported by the car?

For example, using data from this old post:

Kish wrote:I did a drain/range test. Looks like the answer is "no" to my question earlier. I was able to drive a total of 81.2 miles to 1% SOC, at 80 mph (2.5 mi/kWh). The last 10 miles or so was at slower speed (55 mph). My SOH in Torque (110%) was unchanged after a full recharge to 100%.

Let's calculate the kWh actually used/recharged on the car's end:

Before driving:
CEC: 208 kwh
CED: 198 kwh

After driving:
CEC: 210 kwh
CED: 226 kwh

After charging:
CEC: 237 kwh
CED: 226 kwh

kWh used while driving
= total kWh discharged - total kWh charged (regen)
= (226 kWh - 198 kWh) - (210 kWh - 208 kWh)
= 28 kWh - 2 kWh
= 26 kWh

kWh used to charge
= CEC (after charging) - CEC (before charging).
= 237 kWh - 210 kWh
= 27 kwh


Using above numbers would suggest an efficiency of 81.2 miles / 26 kWh = 3.12 miles / kWh. Yet the owner reported that the car's trip computer reported an efficiency of only 2.5 mi/kWh. So why the difference and which number is correct?

The trip computer includes a number (I forget exactly how many, I think it is in the manual) of previous trips. The BMS numbers are the more accurate ones.
