Are electric vehicles deadly dangerous to build and repair? Answered

A local high school tech class is converting a pick-up truck to electric and I got the idea that I could convert our Explorer, (the engine is shot) but an auto mechanic I met told me he can't get insurance to work on an EV due to the danger of the high voltage- this is disappointing to me because I could really get a lot of use from re-purposing this truck to a green(er) vehicle. Help me be more green!

Chosing a Motor for EV Motorcycle

I am thinking of building a EV Motorcycle. But I don't want to make any finical commitment unitl I know exactly how much I have to pay.my question for the day is:i see many motors, and motor controllers that "support regen" i know what regen is, and i don't want a bike without it. but do i have to match a motor that "supports regen" with a controller that "supports regen" or can i just buy any motor with the proper voltage and buy a "regen" controller.i realize that i would be very convient to use a kit like http://www.robotmarketplace.com/products/ETK-ETEKBL250.html but if i can drop the cost, by useing other sites that would be great if you have prefered sites for specific products, that would be great.-thank you for you time.

DIY Design PWM Contoller for 3 HP 36VDC Motor

A friend of mine and myself want to build a couple of small electric utility vehicles to use for chores around my farm and his cabin. We are thinking of something along the lines of the eMule.  http://www.solarevolution.com/eMule/  We just bought 2 new 3HP 36VDC motors for a really great price off of eBay.  See pics. I want to build some PWM controllers for these to help keep the price of the project down and because I like building things. I could use some help though on a few things. How many amps should the controller be rated for? 100 amps? Larger? Are there any designs out there for a DIYer like me? Thanks.

I got a siren!

A little over a month ago, my dad got a siren on eBay. It's the Wolo Model 345, about halfway down the page. Note: if you want one, go through eBay, Wolo wants $64, but this was brand-new for $20. It's not Instructable-worthy, and I don't have enough pictures to make a Slideshow, so I'm using the Forums for their original use. We were originally going to put this on my mom's ZAP Xebra, because it's completely silent and we wanted a way to warn walkers of her approach, but she didn't like it, so I got it to put in out Ford Courier. Since it's electric, I only go 39 in a 40 mph-zone to save range, so I'm often cut off by people going 45. Being electric, the truck has no radiator, just a flat plate of steel. We were already going to paint it black, so we mounted the horn speaker in there. There is an instrument bay overhead, so I stuffed the control box inside an empty slot. Eventually I'll take off the plastic case and mount it in the aluminum sheet to make it much cleaner, but this is fine for now. There were already two extra switches that did nothing, but already had an always-hot line running to them, so I wired it in to that. It can do sirens, animal noises, or a PA. I'm leaving it set to a police-style siren, so if someone cuts me off, I can just flip the switch and give a short blast, then watch them look around for the police car. If I have more time, I can just use the PA to yell at them. Other potential use: I'm going to make a CD of engine sounds. That way I can make my electric sound like an idling Harley at a stoplight. Or a turbine engine. Or a semi. Or a whatever.

speed vs. distance?

Hello All, I am considering building a electric motorcycle in the next year, all the Instructables I have read on the subject boast top speeds of 70 mph and a 10 - 20 mile range. I live in a small city in Canada where the maximum speed limit is 50KMh(~30mph) and the city is not even 7 miles across, also there is nothing outside the city that is close enough to get to with a ev such as this. My question is how does the speed and distance connect, for example, if I was to travel at half the speed would I be able to expect to get double the distance?

Regen Braking Motor Controller

Good morning.... Quick question regarding motor controllers with the facility of regen braking..... For a project of mine I am creating an EV (with a dune buggy chassis), which needs a system to recharge the batteries when been driven or 'towed' by an external force. I've been looking at a 4QD motor controller, which has the regen braking system already built in. My idea is to use the back EMF to charge the batteries. This in theory is quite similar to regen braking, having done a bit of research, and also with some info from the 4QD site itself. I know that if the back EMF is to great, I risk damaging the motor controller. But if there was a way to regulate the back EMF (either by controlling the speed it is been externally driven or with use of electronic circuitry), could I essentially recharge the batteries using this motor controller???! Thanks in advance, Dave

DIY Plug-In Hybrid Pickup Truck

Hi everyone, For a while, I've had this as my "back-burner" project. I'm trying to really get going on it now. It's an Open Source, DIY, Plug-in Diesel/Electric Hybrid Pickup truck. That's really a mouthful, so I'm just calling it the "SuperTruck" project, until I can come up with a better name. The entire concept is that it is a parallel hybrid, which you can charge from the wall, and it has a diesel engine that can run on diesel, bio-diesel, and possibly veggie oil. Either the engine OR forklift motor will be able to propel the vehicle. (Meaning that it will have a dedicated EV mode.) The driver can manually decide to run it on diesel, electric, or both depending on the driving situation. The mechanicals are relatively simple. It uses a manual transmission (rather than a CVT or planetary gearing.) In theory, this will be a project than any advanced grease monkey will be able to duplicate. I'm not much of a car guy, but I have learned quite a bit working on my electric motorcycle, electric car, and experimenting with running my car as a hybrid. Here's a YouTube playlist of what I've got going so far. For the latest on this project, please visit the page for it on my blog: http://300mpg.org/projects/supertruck/ I'll definately need help on this project, so please tell all your friends about it!

Would installing a manual master cylinder in a 1979 Datsun 280ZX be a good idea?

I need to put in a new braking system in a Datsun 280ZX that I am converting to electric. Since there is no vacuum from an engine, I was considering using some sort of vacuum pump but I came upon using a manual master cylinder instead, which is good because it does not require extra power besides my leg, but since my vehicle initially came with power brakes, I am not sure if it will be compatible. I will most likely have to replace all the brake lines, because they are fairly old and there is a good chance that they've been damaged. So this gives me the chance to replace them with suitable lines for either type of master cylinder. Does anyone have any experience with this sort of thing? Any input would be greatly appreciated!

Circuit for electric vehicle? Regenerative braking / free-wheeling?

I'm working on a circuit for an electric trike I plan to build for the local EV challenge competition. I plan to incorporate regenerative "free-wheeling" to recharge the batteries on the down hill sections. S1 closed and S2 open to accelerate the vehicle. S1 open and S2 closed to recharge the batteries while freewheeling down hill. Batteries: sealed lead acid batteries 12V or 24V (depending on motor) Motor: brushed DC motor Would this kind of circuit work? Is it possible to recharge SLA batteries in such a way? Any help and/or suggestions is appreciated. PS. I know it would also be possible to implement regen braking using a full H-bridge, but i think we would be doing more freewheeling than braking on the race track.

In short if you have an Ev and u want to set the ev run on different speeds what are the quantities that have to be checked or monitored (current,voltage) and .If you move from 30 to 40 miles/h what will happen to the variables?
