Still not working, but found some interesting troubleshooting information. 1) Verified that the charger is not in an error state by charging an Ioniq 5 before our test. 2) First test with the 330 ohm to 5V and 2.7K pulldown on the PP line. Response was identical to last trip with no communications e...

I will flash the new version and test again later in the week.

- ground connection from Foccci to the PE of the CCS inlet Tests OK - CP connection from Foccci to the CCS inlet Measures 2.7k to ground - Are all wires of Focccis RF transformer still correctly soldered? Yes, checked with meter - Is it possible to "reset" the charging station, maybe it d...

No communication this time, undo last change... Yes, would have been a good troubleshooting test - but I didn't have the original 1k pull-up that I removed. Have you checked your port contactors that they are not stuck? Iso resistance of port? Does CP measure fine seen from the port? Test also with...

Did more testing today, but no success. I modified the PP circuit to add the 330 ohm pull-up to 5V and a pulldown to ground (tried a couple of values in the 2.2 to 3.2k ohm range). The charger faulted out very quickly. The Opstate stayed at 0 and SOC was not displayed on the charger. I did not recei...

I suspect that it is the PP line. I'm in Canada and it sounds like the PP requirements are different between CCS1 and CCS2. I will try changing the pullup on PP to 330 ohms and 3.3V with a 2.7K pulldown to ground. I also so some other discussions on the forum about another 47K to ground? I don't und...

No charging yet, but progress! When I connected with the PhiPhong Charger, I got up to Opmode 10. The station successfully read the SOC and I was able to see an EVSE Max Voltage and EVSE Max Current value on CAN. Contactors did not close though and the charger went into fault mode. I have attached a...

CAN communications are now working! Spot Values are updating and there are no time-out errors! Just a case of faulty troubleshooting on my part....! I'm ready to attempt a real charge session now.

Any further thoughts on avenues I can investigate on my board? If not, maybe I can purchase one of the new boards on the Web Shop. First race is coming up shortly and I dread the though of once again renting a big Diesel generator.

No CAN activity on 0x108/0x109 regardless of DemoMode setting. I'm assuming the CAN link must work though if the ESP32 board communicates?

Screenshots attached. HV was off. Inlet voltage from sense board(charger side of contactors) reads correctly when contactors are closed and HV on via test. CAN messages batvtg, targeting, chargecur, SOC are being broadcast to the addresses mapped by my Orion2 and are being ready successfully by my d...

I apologize in advance if this in the wrong thread - but I'm still not sure which is the best one to post in. I have now loaded the latest Clara firmware and am now sending "batvtg, targetvtg, SOC, and chargecur" via CAN from my Orion2. I have verified with another device that the data is ...

Thanks johu and uhi22 for your quick response. I am not aware of a separate QCA-Thread. You're right though, separating board/software development and use of Focci/Clara would be a good idea.

I’m finally at the point of being able to test my Focci/Clara setup. I have one of the 5 original V4.1 boards. I’ve reflashed the STM32 with the “stm32_canloader.hex” (Version dated June 23, 2023) and the latest “stm32_ccs.hex” file I could find on the website (1st Release Clara Software dated Dec 1...

I'll stay on the European list. Truthfully, I would rather pay the courier charges so I can take advantage of Uwe's kind offer to finish populating the board, flash, and test it!

I'll take a board as well! There is now a DC fast charger at our local track, so our goal for the 2024 race season is to stop using a diesel generator to charge our Tesla Cobra EV race car. I'm in North America, but will certainly pay for the courier charges.

Interesting method of switching two phases! We are looking at converting our race car to AWD and one option we looked at was to run a front M3 Induction Motor in reverse. Our solution for that option was to mount the inverter remotely and swap two of the cables, but your solution preserves the stock...

Communication is via CANbus. I've attached a datasheet and the CAN protocol. We regularly run these modules at the full 30kW for a full hour with no temperature issues at all.

Sorry "addvalue", I do check in on the board, but I haven't actually signed in for a while so have not seen your PM messages. The supplier we used was: Shenzhen Kaiyuan New Energy Technology Co.,Ltd. 40kW modules are also available now. https://www.alibaba.com/product-detail/UR100030-SW-Fr...

We built a unit using three parallel Gen2 chargers running in parallel for our race car. This provides 27kW of charging. Sounds like you have similar requirements as us. We used 3 separate NEMA 14-50 inlets to allow power from 3 sources. In our case, this was three NEMA outlets from diesel generator...

Just ran across this thread. People seem to be underestimating the capabilities of the Leaf pack. I have enclosed some data from a test report by Idaho National Labs under the DOE Advanced Vehicle Testing Activity Program. They tested every EV pack (except Tesla) up to about 2016 with very detailed ...

We used a Tesla charge receptacle on the car and a Supercharger Plug on the charger side. Ultimately, the charge will be managed by our datalogger/controller. The Orion BMS will act as a supervisory safety which will cut the charge in case our datalogger/controller mis-behaves. For the weekend, we u...

No pics! I was tempted out of curiosity, but decided against it after everything worked.

Over the weekend, we tested a new charger setup using a parallel pair of 30kW Charger Modules from China. Input was 3 phase, 440 V from a diesel generator. The charger performed flawlessly at the fully rated 60kw with no errors or problems. Control is via documented CAN bus commands, so this would b...

There were some benefits with compressed air/mist cooling. Running fluid in the air-gap created more heat from friction than we removed. You do not want to mess with the Model 3 cooling internal cooling design! Air gap is way smaller and there is a very efficient cooling scheme. Rotor cooling is not...
