Marius,
First, let me say that my posts are moderated here, so you may not see this response for days, or even weeks.
It’s always discouraging to read anything like your experiences with any of our products. Sorry for all the issues.
I want to be clear, however, that there is not an “updated” software set. Even if we did change software, we would not update cars that are not experiencing problems.
The CHAdeMO charger side of the software is identical to that used with the 2012-2014 Toyota RAV4 EV. There are about 250 of those throughout North America and Europe, all in use without issue. There are 50 in Norway. There are well over 100 in California, where our company is located. The RAV4 EV is my daily driver, and I have been personally using JdeMO on 4 different RAV4 EVs that I have owned for the past 4 years. I have never had an issue.
We have many customers using the RAV4 EV for Uber service, sometimes charging 4 or 5 times PER DAY with JdeMO. I can assure you that they would be complaining loudly if there was an issue. Of course, the chargers themselves can be finicky, and the networks can be even worse!
We would have to know what specific issues there are before we could address any remedies with your unit. We have a number of these kits operating throughout California on the Tesla Roadster for years now, and none have come to me with these problems. We specifically had the cars in California installed first to test for problems. The original Roadster JdeMO installed 3 years ago (which was and remains a complete “hack job”) has been sold and is in Seattle, where the new owner uses the JdeMO regularly. It works every time, according to him. I’ve tried to convince him to upgrade all the equipment to the current production specification, but he doesn’t want to. He likes it the way it is.
The very first kit sent to Germany worked at first, and then didn’t. It had a blown a fuse (that we didn’t realize until about a month ago) in the car that supplied power to the JdeMO unit. I flew to Barcelona, Spain (where the Roadster was at the time) and swapped the entire control box. It still doesn’t work, even with a fuse replacement. Of course, both JdeMO units that were installed on that Roadster were fully tested personally by me, on a Roadster, here in California. They worked perfect then, or they would not have shipped to the customer.
So, addressing an issue with the car is something entirely different. I don’t know if there is anything in your car that could be contributing to the problem. It can’t be a fuse, or it wouldn’t fail to work once, and then work fine. We could loosen the programming for all the “time outs” related to a loss of CAN communication, which may or may not help. I suspect that there is a possible issue with any car that is not properly transmittting its CAN data set every 100ms, or if there is noise or interference that drops data. Maybe a shielded cable from the underdash CAN source to the control box would help. Currently, JdeMO has a timeout message for a loss of signal greater than 600ms.
The time out feature is the same is on the CHAdeMO charger side, however I seriously doubt that there is an issue there, since ALL the bits are identical to what we use on the RAV4 EV. We previously used two separate printed circuit boards for the RAV4 and Roadster, but now all the RAV4 kits use the Roadster v3.0 JdeMO boards.
My understanding is that the remaining 4 Roadster JdeMO kits sent to Germany have all been removed (or never installed). I asked to visit them in November 2017, after my trip to London and Barcelona, and was told that they didn’t want me to visit at all. I honestly have no idea what issues they may or may not be having.
The Henry Sharp product does not have any software, or even a microprocessor. It’s a simple, dumb mechanical device. We build similar styled adaptors for other vehicles besides the Roadster, like our JDapter Stub™, which allows Tesla charge stations located in North America and Japan to recharge J1772 / Type 1 equipped cars.
In closing, I want you to know that we don’t abandon our customers who are having problems, even if those problems are well after the warranty period. I would say that I personally take extraordinary efforts to address any cars with issues, and thankfully there haven’t been that many. But, a common theme with Roadster issues appears to be the car itself. I suspect that I could take the JdeMO unit that I personally removed in Barcelona and test it on a Roadster here in California, and it will work. I haven’t done that yet, but I will.
The RAV4 EV, and Mercedes B-Class ED / B250e also use Tesla batteries and motors, and are much more reliable than the Roadster.
