Re: [EVDL] winter parking brake
It will still move, a motor with magnets will move slower since any EMF generated will cause a large current (short circuited generator) that counter-acts the movement, but the reaction is proportional to the speed of movement, so at slow speed there will hardly be any counter-action and the vehicle will still roll away, not be held by a short circuited motor. NOTE that this is only the case for motors with an active excitation such as a PM (Permanent Magnet) motor. Any motor without active field will not generate any voltage, so whether shorted or not, so you can turn an ACIM (AC Induction motor) for example as much as you like, it makes no difference if it is shorted or not.

Re: [EVDL] winter parking brake
I used the hand brake often while driving in The Netherlands (same latitude as south Canada) and only had an issue once. Remember that the time brakes will freeze to the rotors/drums is when they are *wet* before parking. If you noticed that you run through something wet (puddle) before parking, you can drive the car another block with the brakes lightly applied (pull the hand brake until it starts slowing down the vehicle) so it gets warm and the brakes dry, before parking. The one time I noticed was after a bright cold winter night, the car would not move backwards, only "upwards". It had frozen on one side. Jogging the car carefully back and forth cracked the drum brake loose and I could drive normally after that.

Re: [EVDL] winter parking brake
When you're at -30 there is likely near zero humidity. On the other hand, in temps from 20-30 there is much higher humidity and I would think brake freezing would be more likely. It's only happened to me a few times. I found that by rocking the car forward and back, gently, they eventually freed up. Hard to do on ice, though.

Re: [EVDL] winter parking brake
I drive in a city like Fresco with steep hills. My EV had a manual transmission where I park down hill, I would turn the wheels to the right and apply the parking brakes even in temperatures down to 33 below. If I park on a up hill street, I than turn the wheels to the left and apply the the parking brakes. In some cases I would not apply the parking brake when my tires are against the the street curbs. What also helps, is to put the transmission in reversed gear on a down hill or in 1st gear in up hill. In either of these gears, the overall gear ratio is over 15:1 or greater which will adds some resistance. The wheel chocks does not work so great, because I had to move the EV off the chocks to relieved the pressure and take a chance to retrieved them. Another thing that could be done, is a mechanical mechanism to apply a locking key into the pilot shaft of motor if it has one. Do not use the brakes so much where it will heat up the pads. I avoid using the brakes when coming to a stop. This will allow the air to cool the brakes.

Re: [EVDL] winter parking brake
Some factory conversions like the US Electricar have added the shifter from the automatic gearbox version, as well as the parking pawl that drops into the teeth on the flywheel IIRC, the rest of the shifter is unused except for operating a switch that tells the controller whether it needs to move the vehicle forward or reverse (and it can activate different regen settings for the different forward "gear" selection positions). For a home conversion - I don't know. Carry a cobblestone to place in front of the wheel?

Could Tesla have left Toyota for BMW?
Tesla previously had a partnership with Toyota, which produced a RAV4 EV.
That relationship is now over, but Tesla is still keen to work with other
major automakers, and vice versa. And now we can confirm that just last week
executives from BMW and Tesla had a sit down meeting to discuss and
strategize the future of electric cars. At the moment, BMW builds the i3 and
i8, but it is actively seeking to develop its EV technologies and Tesla is
perhaps the best partner to collaborate with.
However, Tesla is also speaking to other automakers in order to make new
friends in the industry. In other words, mainstream automakers are now fully
aware that EVs are here to stay. What’s more is that Tesla CEO Elon Musk
made clear that his company is not interested in protecting its technology
patents against others, just so as long as the technology is being used in
"good faith." So basically, Tesla is sort of outsourcing its technology to
help the world at large battle carbon emissions. Musk even made this clear
in a recent blog post: Tesla "can’t build electric cars fast enough to
address the carbon crisis…the world would all benefit from a common,
rapidly-evolving technology platform."

Lightning repeatedly vanquished the darkness like the angriest of strobe lights and thunder shook the building, punctuating the clatter of a heavy Texas rain on the metal roof as the clock ticked away the initial seconds of a rare full moon Friday the 13th. It was then that the Black Zombie came to life for the first time. Beneath the hood of this rust-free 1968 Mustang fastback, a 289-cubic-inch V8 no longer turns gasoline into heat, noise and pollution. As patient zero of Blood Shed Motors, the classic pony car has received a powerful electric transplant, and now boasts twinned Warp 11 DC motors and a pair of fresh Zilla controllers that will serve as the basic blueprint for future vehicles. Dubbed the Zombie 222 drivetrain, the setup will be limited to 750 horsepower in customer's cars to keep the maintenance experience low, and eventually will draw power from a 40-kWh battery pack. In this first example, though, the output is bit more extreme. For one day, at least, they have the 1,500-kW-capable pack that powers the record-setting Swamp Rat 37 racer belonging to Don Garlits and a brief window of opportunity to try it out on a track. Blood Shed Motors is the result of a collaboration between NEDRA co-founder John "Plasma Boy" Wayland, the man who helped bring electric vehicle drag racing to the attention of the world with his unassuming White Zombie Datsun 1200 conversion and Austin, TX business man Mitch Medford, who've put together a small team of experts in their chosen fields. The plan is to build a limited number of muscle car conversions on pristine early Mustang, Camaro, and Barracuda platforms. The plan is to build a limited number of high-quality muscle car conversions on pristine (No restored rust buckets!) early Mustang, Camaro, and Barracuda platforms. Each can be customized according to buyer's wishes and blessed with its own serial number. The price tags will be in the eye-watering $200,000-and-up neighborhood, reflective of the cost and rarity of these cars and the custom nature of the alterations. Of course, you can't just multiply horsepower and add the monster torque that these electric motors put out and expect an antique chassis to hold up. To help keep everything straight and under control in all driving situations – these aren't meant to be quarter-mile queens only, but also enjoyable road machines – the outfit has added subframe connectors and a unique motor cradle that helps stiffen the front end, along with high-performance suspension and other parts. The next evening, the calender still read Friday the 13th as Black Zombie did its first burnout on the asphalt of the San Antonio Raceway, ahead of a couple shakedown runs. There had been no indication to onlookers that the fastback on the track was anything other than what it appeared to be, so as clouds of smoke raised from the spinning rubber, so did eyebrows. Where was the deafening sound? What was powering that thing? A bigger shock was in store, though. As the dragstrip's light tree went green, jaws dropped as the front tires lifted and stayed off the ground for the first 50 yards. A glitch momentarily cut power to the motors and the Mustang seemed to settle. Wayland's foot was still to the floor, however, and so when power somewhat unexpectedly came surging back, the front end again came off the ground despite the 40 miles an hour of forward motion. The car didn't set any records that night. That was not really the aim. Besides, it was not really prepared to go a full quarter mile at life-threatening speeds. (Something about someone who's name rhymes with "pitch" forgetting to reattach a sway bar and no time for a proper front end alignment.) Still, it reassured the Blood Shed bunch that they are on the right track. With the first bit of fun out of the way, the real work begins. Now, with that first bit of fun out of the way, the real work begins. The Bla
