Looks Great, nice plates tooI finally got around to installing the the JdeMO kit on my Roadster 2.0.

1979 Corvette 100% original. 1- owner, 1- driver, 32k miles.Random sidebar... @samcarney, what's hiding under the tarp there? Should we guess?
I am considering chademo but I have no space at the back of the car...
Does anyone has experience with an installation of a cable in the trunk only?
Can you still partially close the boot, right side only? Cable in the crack?
If not possible then just stay with the charging car for 45 minutes?
Anyone have experience with chademo charging in Europe? Which apps do you use to find the chademo stations? In Belgium, France and Germany for instance?
How do you pay for charging in these countries?
Thanks for the help!
Jdemo test Tesla Roadster Sport 2,5 - Road Trip Oslo- Nürburgring
-Some discoveries on the road-
Just after having gotten the Jdemo kit installed, I decided that a real life «unlimited range» test was in order. I set out to drive the car for a lap at Nürburgring, something quite unimaginable not long ago, without the Jdemo (-or a car trailer).
Distance Road Trip: 2.406 km.
Stopped 19 times at CHAdeMO charge spots. Charged DC 14 times at 13 different chargers.
Sum total energy kWh: 394, 95 (Total from AC: ca. 120 kWh, Total from DC: ca. 275 kWh)
Sum km.: 2406, 3
Sum h.: 33h.56m. (Operating time, car in gear)
Average consumption: 164, 1 Wh/km
Average speed: 70,913 km/t (Operating time, car in gear)
Estimated 19 hrs. in search for chargers, and DC-charging. Average speed incl. charging: ca. 45 km/t
-DC charging the Roadster:
The Jdemo unit makes the car read the incoming DC power as regenerative braking. As a safety feature added, the car must be in «P» and handbrake on for it to work. Because the car must be turned on for DC-charging, locking the doors is not possible. (Some OMVS solution to this yet?)
-Regeneration
What came as a surprise to me is how much regeneration is affected by the DC-charging when driving. It seems not to affect on shorter charge-sessions less than 20 min. However, on this trip I was charging 40-70 min. at a time, and when DC- charging for 40 min. or more the regeneration is completely gone when driving on. When gone like this it will not recover until about half the range is consumed. In reality, it meant driving with no regeneration half the time/distance of the total journey.
Moreover, the pattern of absent regeneration stuck with the car after next AC-charging cycle too. Still did not regain regeneration until there was only 150-180 km Ideal range left. When I got home, I found that it took three full charge cycles on AC for the car to normalize the regeneration when driving.
Anyway to address this?
-Power Limit makes DC charging impossible
The car will turn on PowerLimit (yellow text lights up in dash) not only when hot, but also at a low SoC. This happens when there is about 40 km remaining in Ideal Range, std. mode. In Range Mode, the PowerLimit will turn on ca. when it stops showing range, at 37-40 km Ideal Range, Range Mode. (At witch point you will be forced to AC-charge back up past the threshold before any DC-charge can start)
NB! There is a long delay. If you get PowerLimit in STD. Mode, and switch from STD. Mode to range mode, several minutes will pass before the light for PowerLimit comes off. The car/Jdemo will fault the charging as long as the PowerLimit light is present in dash. Wait until it has come off before starting DC-charger.
-Estimated range affected, energy calculation is not affected.
The estimated range is a 3-digit number. As the car «regenerates» on a DC-charge, the estimated range increases. It seems that when estimated range passes 999 km, it goes into a random calculation mode. It will show anything between 0-999 km at random, although it will tend to show 160 km most often, for some unknown reason. It will normalize itself after 60-80 km of driving.
The energy calculation showing the Wh/km ratio and the energy history in the trip-counter is not affected. This must be due to the connected timer for operating time; hence, it does not register energy- input/output when gear is engaged in Park.
-Reset of Jdemo:
At one charger, something happened. The charger read the battery SoC, but aborted on initialization and would not charge. This happened several times, even after a reboot of the DC charger (Efacec). I had contacted the support, and they told me this was a known issue at that location. I had to shut down the car/Jdemo to release the connector.
The interesting part is that the same thing happened at the next charger. And the next, and the next… I was of course worried at this point, and got a tip on the phone from Ravn (a fellow Jdemo-pioneer) to reset the Jdemo simply by disconnecting it from the CANbus, wait a minute and reconnect. I tried first without the reset on a new spot, it did not work. Tried the reset… And it worked. It has worked fine ever since. Nice to know if something similar should happen.

You forgot the important detail.... How was the lap around the ring???
The Jdemo unit makes the car read the incoming DC power as regenerative braking. As a safety feature added, the car must be in «P» and handbrake on for it to work. Because the car must be turned on for DC-charging, locking the doors is not possible. (Some OMVS solution to this yet?)
A while back, for Jdemo users, I added a feature (FEATURE_ROADSTERBITS_LOCKWHILEON) to bypass that restriction. Set feature #10 to 1 to enable this (with latest firmware).
Can be good to have AC cooling of the battery from OMVS to cool the battery extra under charging
The heat raise is 2C for 5 min of charging
Open Vehicles | Open Vehicle Monitoring SystemThank you Mark! I tried this, but it still will not lock while on. I don´t know what "the latest firmware" means, but the app is telling me I run 2.6.5./TR/V2 on app 1.6.6. Not right? What is the solution?
1. NO METHOD TO LOCK CAR WHILE CHARGING - There is an OVMS update to allow you to remotely lock the Roadster from your phone. There may be other clever ways to do that, also, and we may develop a method to lock and unlock the door from the truck / boot (which can be locked and unlocked with the key). You would need to carry two identical Tesla keys; one for the boot, and one for the “ignition”.

I hope to see some of you on my travels.
