Having built a Fisher Fury R1, I'm after building something similar but with electric motors and batteries. Anyone got experience of suitable motors, transmission parts, power control systems, etc. please?
try www.pmlflightlink.com/Depends on the power required. I'm taking one to Stoneleigh with Lithium Iron Phosphate batteries.(LiFeP04) Try www.evparts.com and Netgain technologies who do Warp motors.
PML flightlink are not selling their cheery yellow wheel motors to anyone but big business at the moment so you can forget them. The Warp electric motors are series wound DC motors. Good quality from what I've heard but the technology dates from early last century. Doing a DC motor conversion is definitely the cheapest way to go but it's also the least efficient and gives you only a small amount of regenerative braking. This is where the motion of the car is turned back into electricity when you slow. this can improve your range by around 10%. An AC motor with an inverter/controller gives you regen and will undoubtedly become the standard configuration in EV's of the future.
Your single biggest hassle with any EV is the battery pack. I have done extensive research on the subject and here's the best that's currently available. Go for the 90Ah or 160 Ah unit. You'll be spending over five grand UK to get a decent pack.

There is also someone in th US of A with an electric arial atom (you can find it on youtube) which looks wicked fast.
Also, there is some new battery technology on the way (alledgedly) from eestor (ultra capacitor) and the altair nano (battery). Both claim to use lithium titanate electrodes which allows fast recharge and discharge equivilent to a capacitor but the energy storage density superior to ordinary lithium batteries.
Also see lightning car co which is using 'nanos and 'hypadrive

Didnt see them at Stoneleigh but the Battery Vehicle Society were at Exeter and Newark last year.

There was an electric car stand at Detling show so I would imagine they will also be at Stoneleigh. Didn't clock the name but will probably be in the Detling show web site.

The EEstor caps are an unknown quantity. I have seen a couple of chemistry guys make disparaging remarks about their ultracaps. They can achieve the storage they claim but only in a very narrow temp range. Anything outside this and the devices perform very poorly. EEstor have hoovered up huge amounts of investors money but so far produced very little. They have also failed to demonstrate a working device as far as I know. Words such as "secretive" have been used to characterise their operations. Not sure about the Altair offering, they have made some pretty big claims too. At present the LifePO4 chemistry seems to offer the best energy density and highest capacity per unit of price. There are many manufacturers, YESA, A123 Systems, Thundersky etc etc

They plan to be at Stoneleigh this year.Steve_D said:
