These are the latest changes to the Soliton code.

Bug fixes:

  • Fixed a problem with Quiet mode that might be the root cause for desat errors in some rare situations.
Features:

  • Only run fans when the controller is warmer than 40C.
  • Increase max motor current to 600 Ampere for Junior.
  • Increased maximum allowed temperature for Junior.
Added safety:

  • Added ADC over- and underflow error.
  • Do a sanity check of the current sensor at start up.

No major fixes really but I'd still recommend that everyone upgrade, ESPECIALLY if you run a version older than 1.1! If nothing else the log functionality now gives much more clues to why the controller for example limit the motor current.

Oh, and this also means that Junior finally is available and shipping will begin! :cool:

All right -- You're telling me the Jr is now live so where do I go to look at one and possibly buy one. I see you managed a few more motor amps and that has been my biggest concern. My EV Buggy will be running 128 volts of Lithium and I wouldn't mind adding a little artwork.

P.S. - What is the estimate for the continuous current rating without liquid cooling?

I'm not sure which dealers are likely to have it first - I try to stick to engineering and let Seb/Chris handle the manufacturing and management end of things. I know that Kostov in Sofia, Bulgaria has a standing order for a bunch of them, and a few other dealers have shown interest. Rebirth Auto is almost assuredly going to have some first (as they are our sister company that does conversions, makes motor adapters, etc...). Not sure if anyone in the Pacific Northwest will be carrying them, however. Haven't gotten much traction with dealers out there.

That's difficult to answer... Like Zen-koan difficult. My recommendation is that if your vehicle exceeds 2000 lbs and/or you want to use idle with an automatic transmission that you plan on liquid cooling. The continuous current rating with air cooling looks like it will be somewhere between 225A at the low end and 285A at the high end. It depends alot on duty cycle, ambient temp, pack voltage.

UPS just delivered a brand new baby Junior this week! :D Wow! That's a beautiful piece of work! :D I spent most of Monday evening with it on my lap as I read the manual and studied the connections. I've got a little work to do to change my current wiring to take advantage of some of the Junior's capabilities. But that's a good challenge. I'm very excited to get this installed in Electro-Willys to see how it'll run. Now I just wish the weather would warm up. It was only -26 F this morning. :eek: Makes it hard to work in an unheated garage.

Congratulations on the release! A technically and optically great looking Controller!
There is even less distance between my not having and having an EV grin now :)

Is it true??? From Kostov site...

SJR is capable of 600A peak at up to 340VDC. It has the same extensive list of features as Soliton1 including water cooling and support for an rpm sensor
Yep. But please note that it's 600A peak, not continuous. Don't remember the continuous levels (Tesseract has to tell you those) but IIRC it's in the high 400A's with proper water cooling.
