Yesterday we had a small object strike the M3 windshield near the lower left edge that has turned into a crack extending to nearly the center camera location at the top-middle. One Tesla service tech said that this was not the first comment they'd received. Other Tesla Service people are saying...

Latest photos at the FV SC. The pedestal footings are mostly complete, being backfilled with soil. Conduit installations for the chargers near finished. The big cement block footing for the utility power transformer is now in place. Photos were taken Thursday 7/16 at about 6PM. Much progress...

Not much activity at the site on Saturday 7/11/15. Here are several pictures of the status. I walked clockwise around the fence. The first photos show the 6 pedestals along the side of the building, then the staging area that has a large prefab concrete block (which I suspect is the footing for...

The permit drawings show 8 stalls, which are all located in the "A?" section of the photo on Page-2 of this thread. This is an extremely busy parking lot, as it also serves a Costco. The street on the left is Newhope Street, and the street below the Soup Plantation is Talbert Ave. Talbert turns...

Here are 3 photos taken yesterday at 10105. As you can see, there is significant progress in the parking lot. The photos show the location of the charger cable heads where they connect to the cars. I was told that Tesla will start their construction on 3/19, all things being equal. Enjoy!!

The CAN -formatted conversation between the SuperCharger and the S is NOT CHAdeMO. There are aspects of the interface that transcend the capabilities of CHAdeMO. There is now a team of owners/engineers that are logging these conversations. Analysis is just beginning, and this is a long-term...

spentan: looking at the middle stall (2B) immediately to the right of the gray car in stall 3A, the one which also requires a back-in car orientation and is currently being used by the white car... if the bank (and strip mall customer) angle-in parking that is behind the cars that are in stalls...

Hi rdrcrmatt-- Yours is a very reasonable request. We now have 3 recordings of charges, will have a 4th on Wednesday. A few pages back <nlc> noted that he'd found the SoC. We've also found what we think are current (several places, with different scaling each) and voltage. We need to instrument...

nlc: I hope you think to look here. Please advise your ISP that your private mail is being rejected because: "Deferred: 450 4.3.2 local delivery server failure (#2)" I'm getting the same message from your ISP's server #1. Something is broken!

nlc: Thanks for quick reply. Your thoughts on the data likely to be very interesting to all. Thanks for all the excellent work. Something I forgot to mention: the signal level on Pilot during the digital stream seems to be 0 to +5V. I didn't have a scope, but was measuring the high level at...

nlc: I have a complete log of a charging session. In addition to the ID's you list, the charger transmits ID's 0x244 (both length=0 and 8) and 0x214 (length=8). These files are LARGE, so I'd like to pass them around offline. Is there a PM function where we can privately exchange email...

I think my car was #3 in the testers list. It was really nice to meet Randy, Fred, and Andrew in person. You meet the nicest people at Superchargers!! The site really is UP. I was by there about 5:30 PM with one other owner tanking up. I expect the announcement will happen shortly after Tesla...

No, not from a Tesla employee, but from the next best thing. Keep your fingers crossed. It might be up tomorrow afternoon. THAT would be nice!

Tesla testing starts tomorrow. SDG&E turned over the service. Everyone think good thoughts! :-)

I just drove by the site, and there's NO ACTIVITY. All the cable pedestals are still wrapped in black plastic. I'll check again later.

There's an "ordinary" CAN bus on pins 1-9 that uses 500KBPS data rate (2 uS bit width). I've recorded this bus. Though the levels on pins 6-14 are CAN levels, the protocol is not "ordinary" CAN. The bitrate is on the order of 1 MBPS, but connecting the protocol engine used on pins 1-9 (set to 1...

There are actually 4 Supercharger cabinets, 2 each inside 2 buildings. I didn't get to see the wiring to each Supercharger, and the distribution end wiring was not entirely exposed. So, I suspect there are 4 runs of 480V 3-phase. I'll try to confirm that guess on Monday.

RandyS: Nice picture of the "finished product". Hand over inspection/certification starts at 10AM Monday. :-) Everyone have a great weekend! PS: SJC is a 7-stall system.

The transformer is in place and being hooked up now. The meter in Tesla's cabinet will be hot by close of business today. Turnover inspection is Monday morning. Then Tesla begins testing. More later. :-)

Today's progress (no photo needed): the entire site has been cleaned up and the fence removed, ready for tomorrow's transformer(s) installation. Everyone take a deep breath and think good thoughts! This reporter will be watching to bring you the latest... :-)

nlc: Thanks for the schematics. I knew about the 7660, which dates to the MAX232 family of level shifters. Unfortunately, my junkbox doesn't contain any. Most of my parts are older, so I have to make do with what I have. A new SC is about to come online. I'm ready to record its operation...

Today's progress: Asphalt covered bare ground around pedestals. Crash posts painted bright yellow.

Fred and everyone else that is interested in this SC (I understand from Tesla that there is more interest in this SC going up than in any other location): I go by this site twice a day. I'm now carrying my camera to capture any changes/improvements. Will post the latest within minutes of taking...

Regards my comment earlier about the brake disk showing 2Kohms to GND in the charge connector: The observation was indeed a red herring. When measuring, for example, to pin 4/5 in the OBD connector under the dash, the charge connector GND pin shows direct connection. Surprising what stray grease...

A last tidbit on the topic of the "Resistance to GND" paragraph above: While charging, I'm measuring 2176 ohms between the ground pin in the charge connector and the brake disk plate on the wheel nearest the connector. There is neither any DC or AC measurable. Hmmmm. Methinks there's some GFI...

nlc: To answer your question about the resistance between the PP-to-GND pins of an idle (not yet powered-up) SC, the answer is 450 ohms. I didn't think to press the button to get the "signalling" resistance. I can do that shortly if you really want to know. There's a good possibility that this...

Today's update installment and photo... As you can see from the photo below, the concrete footing around the outside of the transformer encampment has been poured, as well as the anchors for the barrier posts to protect the equipment therein. I could not see that any of the duct tape covering...

This is certainly a workable solution. Personally, I'm not afraid of cutting into insulation and soldering a tap in place, then applying the suitable amount of electrical tape over the connection. This way I'm assured of a good connection and very little chance of unintended consequences. I've...

Thanks nlc and wk057. I'm going back to the J1772 spec to assess the electrical meaning of the various State's, adding hardware and software to emulate the EVSE's end of the connection to the AVR-CAN, then test. I already have in place in the trunk a 3-wire connection to the charging port wiring...

Thanks to C10Cruiser for yesterday's thoughtful remarks. I was inspired to follow up, so I just took the photos below to augment his text. The forming for the pad concrete pour are most visible in the first photo. Something I didn't notice in the previous inspection is the conduit that is just...

nlc: I believe you have reversed the connections from your receive interface to the AVR-CAN on pins EXT2-6 and ext2-20. Nice output data. None of this is CHAdeMO. The only message ID in common is 0x0102, and the correct CHAdeMO length is 8. I can supply code (.c, .hex, or both) for the AVR-CAN...

These photos taken over the lunch hour today. The first two pictures, taken of the space just behind the transformer shack (third photo), show work completed since last night. The second photo show the slab with conduit sweeps coming from the street and going into the transformer shack...

I've never tried to use other than JTAG to flash the AVR-CAN board. I'm sure there's a way, like ISP. When I was first exposed to the family of microcontrollers, I didn't know one interface from the others. Now I know the difference, but since a knowlegable friend gave me an ICE that "just...

Hello Everyone. Background: I rummaged in my junk box, found an available Olimex AVR-CAN Development Board. The product description and schematic can be found at <https://www.olimex.com/Products/AVR/Development/AVR-CAN/>. I think this particular board came from Mouser Electronics, but I'd...

Update: I found my way under the trunk protectors! The three lower pins in the charging port connect to (lower-left pin, viewed from outside the car) a #16 AWG purple wire, (middle) a #8 AWG green wire, and (lower-right) a #16 AWG orange wire. These three wires are wrapped in a black cloth...

nlc: very nice job figuring out the transition from AC to DC signalling on the Pilot line, and the single-ended CAN bitrate. I have an AVR-CAN development board wired and programmed, ready to listen. I also have access to a SuperCharger (SC) locally. I'm under the weather currently, and could...
