Nobody? I know people have dealt with these controllers before. Maybe I need to post in one of their threads.
Hi xrot,My first question is this: If I use a Kelly KDHB controller for regen with a series-wound motor,
I also talked to Kelly about this via Alibaba and email. Here is the response I got:Kelly has a series wound REGEN setup using two controllers. For example I have a KDH09401 with REGEN. The setup would use a KDH09400 to drive the field coil and a KDH09401 to drive armature REGEN.
Apparently this setup will work with any of the Kelly controllers that have a REGEN and non-REGEN model of the same series, and Kelly has the diagrams to do it.
This is the response I got:
Right now we provide dual controllers for series motor regen, such as 09400 to drive field coil, and 09401 to drive armature regen.
Single controller isn't able to do regen with series motor.
Unfortunately, when I mentioned that I was using a 20 kW motor, she told be that Kelly didn't have a controller that would handle that. I am not sure that the motor size is such an issue though. The HV system is as follows:Hi Jackson,
You may consider Dual KDH/B assembly.
This assembly can do regen braking for series wound motor.
The price of assmbly don't include the controllers and DC/DC converter.
You need a KDHA controller and a KDHB controller.
Could you please tell us the rated power and voltage of your motor?
We will recommend two specific controllers for you.
Hi xrot,It was my understanding that a KDHB controller could do REGEN if paired with a second controller,
Might work3 hours down-stream on electric only, 1 hour back up-stream via a 165 hp Honda motor. The battery pack needs to regen during that 1-hour trip.
Yeah, but running at 48V and under 200A he could set it to neutral. It may be predrilled and just need the CEH rotated.I recall that the series motor uses an advanced timing on the brushes that causes fire to shoot out when in regen mode. Hence regen has not been recommended in the past. A better authority than I needs to comment.
Hi xrot,IJust talked to Steven Li again. He confirmed that he could sell me the controller and then have me reflash the micro so that it would do regen at a later date (when the firmware has actually been written). Of course, if Kelly's development team discovers that regen isn't going to work so well after all... I don't know what happens at that point...
