The current "Infineon" controllers sold by Keywin and others as well as the newer 18 FET controllers which are currently being by rebuilt by Methods and Doctorbass are in fact controllers which are designed by Xie-Chang. There are controllers with the Infineon XC846 microcontroller as well as some that use a microcontroller called the XCKJ 8B116A, which I suspect is either a proprietary microcontroller or a knockoff of some other microcontroller. While Xie-Chang has a reasonably extensive product line, all their documentation is in Chinese.
I've taken the liberty of downloading all their documents, and I've converted them all to editable MS Word format, for ease of translating. I hope that some of our Endless Sphere folks can read Chinese and help translate these documents, since the Xie-Chang controller design is ubiquitous. These editable documents are attached below in a .zip file.
By the way, the controller I have came from Keywin and is his 72V/45A 1500W model. It is an OEM controller from Xie-Chang (with some finishing touches no doubt from Keywin) and is the EB812XC-A-B. An earlier version of this board (EB812XC-A-6) is in the controller which is dissected in the thread Infineon XC846 72V 45 Amp Controller. If any of you are familiar with this model, I could use some help as I'm still sorting out the issues with hooking this up to a Puma.
So with the hopes that some of y'all can read Chinese, here are the docs:
