Masterflux recommendations for Battery Powered Applications

Posted on May 19, 2011 by Aaron Choate

Masterflux has recently added recommendations for how to reduce the impact of input power voltage/current ripple on controller performance. In some cases, the batteries in an electric vehicle will sag under load and the car’s motor controller may attempt to rob power from the low impedance capacitors in the Masterflux system’s motor controller. To prevent this, Masterflux recommends using a diode such as the Powerex – CS240650 – Diode Module, 600V, 50A, POW-R-BLOK.

UPDATE (7/6/2011) REVOLT has listed this part in our store and we bundle it as an option with our mid and high voltage kits. You will find it in our store here:

For the full details, please refer to the full high voltage bulletin on the Masterflux site.

Electric Vehicle Air Conditioning – low voltage from Masterflux

Posted on April 19, 2011 by Aaron Choate

Our “low voltage” configuration is for vehicles with traction packs that are roughly 70V to 90V.  The controller has both a low and high voltage cutoff at 55V and 110V respectively so be aware of your full charge voltage as well as how far your pack will sag as it depletes under load.

We suggest that you purchase the following Masterflux components:

The links above go into the REVOLT Electric Vehicle components store where you should be able to process your order and find more details on the components.  If an item is out of stock, you can go ahead and order it and we will get it from Masterflux as quickly as possible.  It can take up to 10-12 weeks, but they often ship much quicker than that.

If you have any questions, please feel free to ask via the store’s contact form and we’ll get right back to you.

Mounting system for the digitization arm

Digitization setup for the Audi A3 engine bay

Digitization setup for the Audi A3 engine bay

This is the rig that Chris is using to digitize the key surfaces in the electric Audi A3 project. It holds the digitization arm in a stable position so that we don’t have to worry about introducing any inaccuracies from movement of the base of the arm.
