    Follow up to employee termination

    I wholeheartedly agree. I cannot quite conceive the mindset of those defending Tesla on this matter. If he was authorized AT ALL to communicate with sales prospects by e-mail, any guidelines should have been made clear and in writing PRIOR to a snafu. If they weren't, it's just one of many...

    Is it safe to connect a large inverter to the 12V battery?

    The Tesla Model S DC-DC converter is rated at 2500 watts. That's a little over 200 amps. I see know reason you couldn't do 2000watt inverter with 3000 watt surge off the 12v battery. You would need to connect it directly to the 12v battery terminals of course.

    Powering home from Tesla

    We have a 20kW inverter now that runs directly off of a full Tesla battery pack. Shuts down automatically at a little over 300v. Will make power up to 450v. You can power your entire house with your car. Provides 240vac split phase power. EVTV Motor Verks Store: 20kW Inverter for Tesla Full...

    Solar Charging Model S Battery Pack

    I am working on a system to incorporate a battery pack from a Tesla Model S into a Solar system for the home. This uses the entire pack from salvage as is. Yesterday, I discharged the pack down to about 1.4% state of charge using a 20kW inverter to the point where the internal BMS master board...

    Let the hacking begin... (Model S parts on the bench)

    So, not to be condescending, but it would appear my inquiry has indeed hit a nerve. I'll drop it. It appears it is you with product plans... Your characterization as to my contribution in all of this displays kind of an all encompassing ignorance of the thread. I've been working with Jason on...

    Let the hacking begin... (Model S parts on the bench)

    Well,....er.....we hope. Now if you fully DISCHARGE your car and take the same readings, I think you'll find things don't match quite as well. This offset/scalar combination or "linear equation" comes up a lot in CAN. I think we're pretty close. You're at 3072/2.379. At 392 volts...

    Let the hacking begin... (Model S parts on the bench)

    I guess I don't see the point. The Tesla SavvyCAN box is a box, a harness, and the EVTVDue CAN Microcontroller. That board is $99. The expense comes in connectors, wiring hte harness, and the enclosure. Which is why the Tesla box is $299. If you want to do it yourself, the board is $99...

    Let the hacking begin... (Model S parts on the bench)

    Well, if your interest is temperatures from the drive train, the Inverter actually has SIX sensors. I haven't had much luck mapping WHICH sensor is WHICH byte, but it looks pretty good. 0x306 1000 ms 8 bytes 4F 4D 6F 52 4D 4E AE 7D The first six bytes all seem to be temperature...

    Let the hacking begin... (Model S parts on the bench)

    Yah. It's 24 messages with four battery voltages in each, followed by 8 with temp sensors. The first byte is an index so you know where in the pack you are. The other 7bytes are a 56 bit packed array with each value being 13 bits and a trailing flag noting whether it is voltage or...

    Let the hacking begin... (Model S parts on the bench)

    Well yes, that's rather the issue. The dongle doesn't matter as long as it works. Unfortunatelyl, the Tesla does some higher packet loads than like a VOlt or a Leaf so you need something moderately quick. But after that it is a software game. I don't think anything can touch Collin's...

    Reading Battery Voltages and Temperatures via CAN on Model S

    Well yes, this is a quick and dirty that spits out ASCII text through thte USB port of an Arduino Due. If you want to glam it up, a 5 inch LCD display would do nicely. CAC? Not sure what you mean there. You can toggle debug by entering a D and actually see ALL the CAN messages appearing on...

    Reading Battery Voltages and Temperatures via CAN on Model S

    We've sold a fair number of our SavvyCAN for Tesla Model S http://store.evtv.me/proddetail.php?prod=TeslaCANKit&cat=28. But this tends to be for the real deal geeks out there that want to log off and analyze CAN message traffic primarily from the Drive Train CAN bus. However, Arthur Hebert...

    Let the hacking begin... (Model S parts on the bench)

    I guess you would call it a checksum or CRC in a way. Tesla does some very tricky stuff that initially looks like it is trying to prevent tampering. I guess with some further experience with it, I think it's more a data integrity thing applied to a number of messages that are kind of critical...

    Let the hacking begin... (Model S parts on the bench)

    This is causing an awful lot of hand wringing here guys. But you're frothing at nothing here. Sure, you should take it very seriously in the matter of people braking into your car over the wireless or via the Tesla computer system. Those kinds of vulnerabilities can cause damage and there are...

    Drive Unit Replacement Poll

    I might suggest a possible cause for these geardrive bearing issues. AC induction motors are a bit peculiar. The field in the rotor is the result of currents "induced" by the field in the stator windings. But this obviously causes a bit of voltage differential between the rotor and frame...

    How does a Supercharger work?

    Ok. I can't take it anymore. I try not to post to these forums because it enrages all the poseurs and wannabees. But I can't take it any more on this supercharger thing. There is no magic. they are 12 chargers JUST like the ones in your car. When you connect AC to your car on your home...

    Do We Own Our Vehicles? General Motors Says No.

    Most of this discussion of rights is theoretical. But the concept of right to repair is not. The interesting thing about the Massachussetts law, aside from Tesla attempting to ONLY make their service.teslamotors.com site available there, is that it passed with an 85% margin. There is NO case...

    Production vs. Conversion, Model S Drivetrain, EVTV coverage etc.

    It is all there to view JRP. And your characterizations are a deliberate and malicious lie. I've never been kicked off of any board anywhere. I've resigned from several cess pools that you love to inhabit. And have had to DEMAND my account be closed on several occasions when they simply...

    Production vs. Conversion, Model S Drivetrain, EVTV coverage etc.

    QWK. You really do have some sort of reading/writing thing going on here. I'm not certain you're serious. The entire premise, of essentially a GUESS, is that electric motors apply torque in a much faster moment of inertia than an ICE engine car. It doesn't matter if you make 1600 foot lbs of...

    EVTV on Tesla 8/23/13

    Well, GM has a new CEO and he's not very much in the Not Invented Here camp. In fact, he's slashed the R&D budget after noting that of the many celebrated patents in their portfolio, precious few have made it into a car in recent years. He's also set up a team to "study" Tesla. There are...

    Devils advocating...from someone who shorted TSLA

    The document you cite shows the 80% capacity level as low as 600 cycles. 80% is the level customarily cited in life cycle testing. It is true it does flatten out a bit after that. But 70% is pretty much a substantial decrease in range. The second reference is for an entirely different 400...

    Devils advocating...from someone who shorted TSLA

    Realist: Frankly there is nothing wrong with your thinking process. The series of well over a dozen bankruptcies of electric car companies makes your point that getting into the car business is hard work. I recognized kind of early on that the shorts would not have the deep knowledge to be...

    Same guy Coconut. I've moved to my original hometown of Cape Girardeau Missouri. Today I do something very like Boardwatch, but it is a weekly two hour video, and it is about converting cars to electric drive. It's a lot of fun. We are having a convention in August -6th to 11 with a couple...

    Devils advocating...from someone who shorted TSLA

    As I said. I think there will be a build in stock price leading up to the Q2 numbers and a bit of a dip after the announcement. But if they ARE up to 550 per week, and show say 450 average across the quarter, they'll be over 5000 units. The dip will be driven by more fundamentalist shorts...

    Ok. A few words of help. I feel your pain. It's a bit of a mess. But for the past 20 years all the 10 baggers have been disruptive technology companies with huge growth factors. The key element to watch is of course growth management. That growth is the kind of problem to have doesn't...

    Rumor: Apple buying Tesla

    Those are hurtful words caveman. I am pouring my heart out for two hours a week in those videos. I'm working 24x7x7 just to make those precious moments on video come alive. And you don't like me just because I'm little, and ugly and my mother dresses me funny? I'm crushed. I may never do...

    Rumor: Apple buying Tesla

    Actually, it reads APPLE ACQUIRES TESLA MOTORS On a Cold Day in July in Cape Girardeau Missouri. A rather obvious play on "a cold day in hell." This is also a tie-in, for those unfamiliar with some cold temperature battery testing we did during a very HOT week in July. Apparently our viewers...

    Rumor: Apple buying Tesla

    Actually we talk about it quite a bit in the video. This blog is largely extra information, charts and links to accompany a weekly video on electric vehicle construction. If you don't watch the video, it probably doesn't make much sense on its own. Jack Rickard EVTV Motor Verks | Electric...

    Rumor: Apple buying Tesla

    Why would they want to invest in a LOSER. The whole point is that Apple very much NEEDS acquisitions, and acquisitions of a size to do any good in their own space leads to a jungle of anti competitive hearings. If they move OUT of their space, that goes away. The automotive market offers...

    Actually, I would like this story BETTER if Elon bought Apple. How about it Elon? Now if you think that sounds ridiculous, I went through this in 1998. I called a company that was 10 times my size and publicly traded that I was calling to buy their company. They told me that was ridiculous...

    Rumor: Apple buying Tesla

    They cannot have 95% year on year growth by selling more iPads. At some point everyone has an iPad. At some point everyone HAS an iPhone. And actually they have a third problem. The Android movement, because it is much more open than Apple's IOS, is gaining sway. Some say Samsung phones are...

    Rumor: Apple buying Tesla

    Actually, it would be a brilliant move for Apple to buy Tesla, as well as SpaceX and Solar City. Apple has a couple of looming problems. First is their CEO is an able administrator and really an accomplished executive. But he is not an visionary leader. The deal will be to buy all three...

    Woah - No new Roadsters 2012-2013?

    Actually, I think you're all pretty much missing the point. Not only can Tesla switch from Elise to Evora for that, they would have very strong reasons to do just that. Evora is a larger car, and MUCH easier to get into and out of by all reports. More importantl, it is a 2+2, with a very...
