Hey guys!
I got a tip from CNC Dave about some stuff going on at Castle. So, I gave them a call. I spoke with Bernie in tech support. We spoke for over a half hour. It looks like they are working on a 140 amp HV controller with on-board data logging including current ripple logging! It must have crazy fast sampling rate to capture current ripple.
Anyway, they are in the design stage right now. This should not be a hugely time consuming thing like the SHV line has been because they are using an established platform in their HV110 ESC. This is an entirely new controller. However, they are borrowing heavily from the HV110 design for this new "ICE HV 140" controller.
Apparently they are using the HV110 new style FET board that are now fully populated with higher quality FETs and an entirely new controller board with higher gate current available along with new firmware and data logging. This is truely good news!
Beyond that, we spoke about the new HV110 that uses very thin and wide FETs. These are the HV110s that have been shipping over the last few months. Bernie told me the thermal transfer rate of the new FETs is far beyond the old style. That yeilds a far more thermally stable ESC as well as allowing greater amp draw. He said the new style HV110 (again these have been shipping for a couple months now) has surplus gate current now that they are using fewer more efficient FETs. That is resulting in lower heat as well. I can attest to this in my PK Ripper. The ESCs on that bike run nice and cool no matter how hard I abuse those poor things.
Anyway, I have been trying to get onto their BETA test list for over a year to no avail. But Bernie told me I have (in his opinion) more RC E-bike experience and anyone else and he would try to get me on the ICE HV 140 BETA list. He said giving me a ESC to run in a bike is like of like saying "Here, beat on this with a hammer for a half hour........" So, he said that would be a great bit of info for them.
I asked about current limiting. He said they are not doing it because in the RC market, the limit would be turned off in most applications and the controllers could not be warranteed then and that would be a hassle. So, no limiting for now. But, he also said these new controllers should be FAR more stable than even the new HV110. So limitting may not be much needed.
At any rate, I am excited to see what comes along the pike!
