Configurable 5kW  Charger
Previous1 of 5Next
5kW Configurable Charger 

For budget minded EV builders, the Hangzhou TieCheng charger (TC Charger), also known as the Chennic or Elcon charger (two trading companies that sell it). has emerged as the low cost charger option.  The drawback is that you must select a charge profile when you order it, and it is permanently configured.  It cannot be changed by the end user.  If you make changes to your battery pack and need it to charge to a different voltage, you must send it off  to have it "reprogrammed."  As most EV builders make changes to their battery packs, move chargers between vehicles and builds, this can be very inconveient.

But the power electronics are reasonably good and the charger has been mostly reliable and accurate.  EVTV has now developed an Arduino Due based serial controller that controls this charger through the CAN port on the charger..  We've added a sturdy aluminum enclosure for this to help block EMI/RFI, a DC to DC converter and powerup relay to startup when the charger starts up and isolate our power source from the noisy vehicle 12v system, and added a hardened USB port so you can configure this controller with any laptop with terminal program over USB.

The result is a reasonably priced charger you CAN easily control to change the charge voltage, current, and termination.  And we've made it ridiculously simple.  The controller puts out a serial ASCII one line messege that shows your target voltage, charge current, termination setting, ampere-hours, and kilowatt hours.  You can plug in ANY laptop with ANY serial terminal program to this device and watch it for hours on end - the fun never ends.

1 Siemens 1PV5135-4WS14 AC Induction Motor
Previous1 of 4Next

Siemens 1PV5135 4WS14 AC Induction Motor

This is perhaps the most unusual AC Induction Motor in the world.  Siemens makes extremely high quality heavy duty AC induction motors - mostly for yachts and busses, but some trains as well.  This motor was specially produced for the Azure Dynamics Ford eTransit Connect project and we obtained a large lot  of these motors, brand new in the box, from the Azure Dynamics liquidation auction.

What is so unusual about these motors is that Siemens typically designs very high voltage (600-750v) three phase AC induction motors.  This motor was specially produced for AZD and is wound for a relatively low 215vdc.  Azure Dynamics used them with a 335v pack using their DMOC645 inverter controller.

These are voltages much more amenable to conversion vehicles.  The motor was tested to 221 foot lbs - 297 Newton Meters at 300v and 400 amps.  This is the equivalent of 134 horsepower.

Liquid cooled: 50% glycol/water at 16 liters/min

This unit is tagged at a nominal voltage of 215 volts and 47 kW continous power at variance with the data sheet on this motor.  It was probably specially wound by Seimens for the Azure Dynamics eTransit Connect project.

Brammo  GVM Traction Motor
Previous1 of 9Next
 GVM145-2

This is a close variant to the motor BRAMMO uses for their famous motorcycles.  This version produces 40kW peak power (74 Newton Meters/54.5 ft lbs.).  This is a very small, light, powerful liquid cooled motor ideal for motorcycle applications.

 Internal Permanent Magnet AC (IPMAC) motor with six poles and capable of voltages up to 450vdc and currents up to 600A rms.  Produces 52 horsepower at 5000 rpm in a package 7 inches in diameter and 10 inches long weighing just 32 lbs.  That's 2.5kW per kilogram.

We picked up a small number of this from a company who never had them out of the box.  These motors list for over $3500 from BRAMMO.

Brusa NLG513-U1-O1l Charger
Previous1 of 3Next
Brusa NLG513-U1-O1l 3.3kW Charger 

Our first charger was a Brusa NLG513 model and we use them still in Speedster Redux, the Electric Spyder 550 and the 2009 Mini Cooper Clubman.

These chargers are quite configurable, very high quality fo build, and reliable. They are also largely unsupported here in the U.S. by the manufacturer and with the rise of the Euro from 88 cents to 1.35 the price climbed to nearly $4000 each. So its been awhile since we've purchased any.

As part of the Azure Dynamics Liquidation auction we purchased a block lot of 48 of these excellent chargers new in box on a pallet. And so we are able to offer the to our viewers for a limited time at a firesale price. These are currently listed online elsewhere at $2995. We've recently learned the WHOLESALE price on these in quantity 50 is about $2725 USD plus shipping from Switzerland. And Brusa has announced they will discontinue the charger after August 2013.

Quaife ATB Limited Slip Differential for Tesla Model S
Previous1 of 3Next
 The QDH2T is a direct replacement for the standard open differential in the Tesla Model S.

Unlike a conventional plate-style limited slip differential, the Quaife ATB differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The ATB differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.

The ATB differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.

The ATB differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.

With over 370 applications, the Quaife ATB Helical LSD differential is second to none. Accept no imitations!

Quaife ATB differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment.

The Quaife ATB differential is also now subject to a lifetime warranty (subject to terms and conditions).

Please confirm your application using the attached technical drawing.
