I'm thinking of using one in a bike.

Too cold here in the winter for bikes. Brrrrr!

For an EV controller something like 200a 144v would be good. SDHV - Super Duper High Voltage

EHV = Extra/Extreme High Voltage. Rolls off the tongue a bit better. :wink:

That still leaves room for UHV (Ultra/Ultimate High Voltage) for the ~400v setups. :smile:

90v is pretty good on an EV too, but I would limit it to motorcycle or golf cart use. A 24 horse system has pretty good kick.

Too bad the system is out of my price range. It is a lot of cash, especially when I have the 50v plane controllers and some china controllers already sitting here waiting for projects.

There are lots of controller companies out there. Off the top of my head there is curtis and kelly. They are relativly cheap. A 90v kelly 200a was under 300 IIRC.

They are cheap, but much bigger than the castle unit. MUCH! I have a 70v 45a controller here that is cheap too, but it has ridiculously choppy throttle, horrible sensorless commutation, no programming, and is the size of a demi-loaf of bread.

You get what you pay for. Like I said, I have enough controllers sitting around to keep me from splurging on the castle unit. Gotta get my mini bike running again first!

EV usually use one of these.

Z2K:

2000A
375V

Zilla Specifications

* Maximum nominal input voltage range for Lead Acid batteries: 72 to 348 volts.
* Absolute maximum fully loaded input voltage range: 36 to 400 volts**
* Maximum motor current at 50°C heatsink temperature: 2000 Amps for Z2K, 1000 Amps for Z1K
* Maximum Battery Current at 200V: 1900 Amps for Z2K, 950 Amps for Z1K
* Maximum Battery Current at 300V: 1770 Amps for Z2K, 885 Amps for Z1K
* Maximum Battery Current at 400V: 1600 Amps for Z2K, 800 Amps for Z1K
* Continuous motor current @ 50°C coolant temp & 100% Duty Cycle: over 600 Amps for Z2K, 300 Amps for Z1K
* Peak Power: 640,000 Watts for Z2K, 320,000 Watts for Z1K
* PWM frequency 15.7 kHz
* Power devices IGBT
* Voltage Drop: < 1.9 volts at maximum current.

** At this time we are suggesting not exceeding 375 volts on the EHV models, we hope to bring that back up to 400 volts with further testing

Dimensions

Dimensions of the Zilla Z2K 2000 Amp Controller:
7.00" Wide, 4.63" High, 14.75" Long, Weight 29.5 lb.

Sweet! I'm gunna get that the second I have $5200 laying around along with a custom made giant brushless motor...

I didn't know that Zilla's were for brushless motors.

They're not. It would be nice if they made ESCs for the ever popular 3 phase motors though.

That's a lot of $$, even for an EV.. There are cheaper ways to get "ride-on" power..

does anyone know the dimensions of the 200A SHV esc?

From the special projects page:

L: 4.875” (123mm)
W. 3.75” (95.25mm)
H: 1.25” (31.75mm)

They has stopped making the zilla...not sure if that is temporary or permanent...

I am building a full size ev car and the curtis controllers seem like the best bet so far. I am using a brushed motor though. According to everything I have read they brushes will last for around 80k miles!
