Re: [EVDL] winter parking brake
Medium duty trucks used to have drive shaft brakes that could be cobbled from junkyard parts. I use the hand brake on all manner of vehicles (yes, sometimes up north in the winter). I do not find this to be a problem. Is this just habit based on older vehicles? I seem to remember having to jog some truck other to get the rear wheels to turn, but I didn't quit using the E brake all together and the problem was not chronic. Another alternative is to turn your wheels so thy hit the curb. You need a little incline for this.

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
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 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
Help me here. I thought that if you shorted across the motor cables it would not move, no? Mark Grasser as well as the parking pawl that drops into the teeth on the flywheel IIRC The MES drive has an output to activate a parking pawl when in electronic park. I never implemented it but I thought it was a great idea. On Fri, Jun 20, 2014 at 9:47 AM, John Lussmyer via EV ev@lists.evdl.org wrote: Probably Wheel Chocks would be the next choice.

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.
