Quick Charging

Dino said:

Why don’t they use the EV’s “motor controller” as a charger? It seems to me that you could disconnect the motor and connect power directly to the controller and charge the battery as you would during braking regen. Even if had to be three phase and you couldn’t do it at home, couldn’t it replace the need for a DC quick charger? But I guess the rate or kw capacity would be limited to what the controller is capable of delivering, probably need more cooling for the controller among other things But might we see this in the future? Or am I missing something.

AC Propulsion has a patent on this technology and, perhaps, Nissan did not want to pay to license it. But, yes, it does make far more sense and was used on vehicles such as the Mini-E. As in the Mini, it does also generally allow for much higher charging rates.

I suppose someone has a patent on using the “motor controller” for V2G too. I guess don’t really get the whole “patent” thing. It seems to put a damper on progress in the name of profit, eg. Bloom energy

I certainly would not argue against the supposition that the U.S. patent system is seriously broken...

In 1994, AC Propulsion unveiled the AC-150, an innovative 200 horsepower integrated drive system for compact to mid-size passenger cars that attained 0-60 mph acceleration in 6.2 seconds and a 145-mile range. In 1997, AC Propulsion introduced the original tzero™ sports car at the LA Auto Show, and showcased its capability for 0-60 mph in 4.9 seconds, while reliably achieving a 80-100 mile driving range. In 2006, AC Propulsion created the eBox, the world's first vehicle-to-grid (V2G) capable electric vehicle.

Since then, AC Propulsion has issued and owns 6 patents on electric vehicle technology, many of which have been customized for our technology and automotive customers globally.
