Azure Dynamics Force Drive DMOC 645 Inverter
Previous1 of 3Next

Azure Dynamics Force Drive Digital Motor Controller (DMOC) Model 645


This is the Azure Dynamics 3-phase AC Motor Inverter.   This device is controlled by CANbus messages to drive the Seimens 1PV 5135-4WS14-Z AC Induction Motor.

Azure Dynamics was liquidated in November 2012 and we acquired a quantity of these in a liquidation sale. These are orphans as  there is no product support, warranty, or repair services from the manufacturer for this inverter.  

It was specially configured for the Ford eTransit Connect vehicle, and has no software to allow a stand alone operation.  It  requires a Vehicle Control Unit (VCU) to translate driver inputs into appropriate Controller Area Network (CAN) messages to control the inverter.

This is the configuration  used in our VW THING build and it works quite well, developing about 145 horsepower with the Siemens motor..

Configurable 5kW  Charger

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.

36kW MPPT Solar Charge Controller for Tesla Model S Battery
Previous1 of 5Next
 There are now over ONE BRAZLLIAN different weeny cheap charge controllers in the solar market.  ALL of them are for 24/36/48 vdc and do less than 3 kW.  Worse, ALMOST all of them allow a Photovoltaic Arrary input of a MAXIMUM of 100 or 150vdc.

And almost all currently grid-tied professional solar installations use PV array strings of 400 to 600 vdc.  This allows the use of smaller cables and less line loss on longer cable runs.

We had this controller designed specifically to charge the Tesla Model S full battery pack at up to 400vdc.  And we insisted on a PV array input maximum of 750 vdc.  Bettter it features a whopping 36kW of power putting out up to 100A at 360vdc to your battery.  That means you can FULLY charge a Tesla Model S 85kWh battery pack in less than 3 hours of sunshine.

It's the most powerful solar charge controller we have seen.  It has the highest max PV input voltage.  And we just can't find anything to charge a battery to 400vdc.   Not just at this price point.  At ANY price point.

It's simple.  It's powerful.  And it's selfish.  It does one thing, and it does it very very well.

Brusa NLG513-U1-O1l Charger

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. 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. 

Excellent for use as Selfish Solar isolated charger for Tesla Battery Packs.

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.
