It's been going for a long, long time. To mention just a few: Too many people die due to not wearing seatbelt = seatbelt laws. Ford Explorers roll over because of low tire pressure = mandated TPMS sensors in ALL car tires. Insurance companies paying out because so many cars are stollen = $$$ key with ID transducer chip. Record number of car companies being sued for record amounts for failure to recall cars with (known to them) defects = ability to reprogram car, including deactivating it if it might be unsafe. I'm all for Right to Repair! My dealership sucks big time. I want the right to chose who repairs my car AND I'm willing to suffer whatever consequences for not taking it to the dealership. I do as much of my own service as I can, I take whatever repairs I want to an independent mechanic of MY choice and I check over all the dealership only service because they screw things up more often than not. Big deal Tesla can deactivate the cars it built! The Tesla is just a computer designed to look and work like a car. If it's your car then reverse engineer the software hardware and make it your own! Heck, you could even go in and disable Tesla's ability to disable it. Or talk to it. No, it's not easy, pretty near impossible, but not impossible and some of it so simple as to be overlooked. It's just a game of cat and mouse. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/EValert-Don-t-buy-a-salvaged-Tesla-EV-to-repair-drive-video-tp4671831p4671963.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
Re: [EVDL] Really efficient electric drive trains and what they are?

They said these motors were 98 % efficient. I thought the run of the mill ADC motor with a Curtis controller was 90 % and brushless were a bit more efficient. Are these motors worth the 10's of thousands they cost? Are there motorcycle/bicycle hub motors we can buy that are very efficient? Each of the Stella motors are 20kw. Some bicycle hub motors are very powerful. 10 or more kw. Is there a loss of efficiency with these new powerful motors? What do I need to compliment a very aerodynamic body/go freeway speeds not suck the life out of my batteries? I'm certainly no motor expert, but my understanding is that PM motors only get that high efficiency at max power. The cogging effect (the field is always there) hurts efficiency everywhere else, and a road vehicle spends virtually all of its time NOT at max power. Other attractions of PM motors are their relatively light weight and ease of implementing regen. Those who have converted motorcycles have used these advantages, but some have come to realize they come at a cost. Light weight also means a greater tendency to overheat. Startup torque can be underwhelming. Series motors solve these issues nicely, and also coast freely. I don't want to re-start the coasting vs. regen debate, but coasting with no regen can be a pretty effective range enhancement. The other issue is hub motors. To my knowledge, no-one has made these work on an everyday on-road vehicle. The main concern is unsprung weight, which will be even more of an issue in a hyperlight car. If you want to give a try anyway I'd suggest scooter hub motors, because they have presumably been designed to survive the pounding an unsprung component gets. But the ones I've seen have been designed more for cost than efficiency. If it was me doing this, I'd probably go the Tropica route. Use small series motors near the drive wheels. Use trailing arm suspension and mount the motors at or near the trailing arm pivot, with belt or chain drive to the wheels. That should get you a solution close to what you're looking for with low risk. You're going to have your hands more than full with all the other aspects of this vehicle. Getting hub motors to work well is a whole 'nother project by itself. Chris -- next part -- An HTML attachment was scrubbed...

Those rules govern how much PV square area it has, how big a battery, I think how much motor power, and probably much more.

Re: [EVDL] Open source software to control donor ICE's CPUs
Automotive CPU, MPU, ECU, etc. are often designed using in ASICs (Application Specific Integrated Circuits) and nowadays FPGAs (Field Gate Programmable Arrays). The software is not served up by a drive, or kept on a flashable EEPROM, it is literally built into the silicon. Or in the case of an FPGA it is mapped onto an all purpose Gate Array - essentially hardware, not software. The OS is real time, or deterministic, so there is less glitchiness and no need for fancy GUIs and such (there are certainly higher level GUIs like Teslas, but at the functional level (not the wants and needs of the operator level) of running the car, a deterministic control system is very attractive.). This is definitely the better way to operate equipment. It may require the original the development system to reprogram it. Or it can only be reprogrammed by replacing chips and boards - meaning it is very unlikely a DIYer will have the ability to hack it. Far more likely to strip off the salvaged control system and use more basic systems. Hard to see how a salvaged Tesla, with all its controls removed and DIY ones installed would be a satisfactory result. The OEM controls are the result of many thousands of hours of programming by some of the best minds silicon valley has to offer. The reality is, cars have achieved levels of sophistication and function with the Tesla,, and high end ICE, that scratch built alternatives night not be very popular.
