I work for AEM so maybe I can answer any questions you have. I am not here officially but if it's info I can share I will.
The VCU 200 is shipping now (this thread is titled VCU200) but I think you are really talking about the Tesla base LDU board right?Biggest question is "When", and how plug-and-play is it? I'm not looking to squeeze every last ounce of torque out of my Tesla LDU, I just want something that will let me hook-up and go relatively easily.
Don't know about Rywire. I have not had anything to do with them or any project they are working on.Do you know if "Rywire" is up and running with the VCU-200? Do you know of any customers that have paid, received, and are using the VCU-200 successfully in a complete EV?
I am not working on that specific project so I don't have dates or anything like that but I can say that it seems to either be complete and may just be in the buttoning up phase. Last I saw they were validating very high speed regen so there cant be much left if anything.Correct, specifically the LDU. I think I have plans for everything else that's just the last component... (I think)
You can definitely control the A/C with PWM and keep the VCU completely out of it. For the VCU to do it then it needs to be one of the CAN based compressor units. Without that the VCU cant use the A/C along with a chiller to cool the batteries.I think I can do everything but A/C, cause I'm using a PWM (not CAN) compressor, unless the VCU200 will drive that. Otherwise I am totally fine running everything with the VCU (in fact I was hoping to).
Yes. The ability to add the A/C chiller to either the battery or inverter cooling loops just gives you more options when ambient temps are very high and you are loading the systems. Not terribly necessary for the battery loop but supercooling the motor/inverter loop before a run allows you to run harder longer.I think I am misunderstanding something here. I'm intending to use a traditional coolant system and Tesla coolant heater for temperature control of the batteries. I expect I'll be able to manage both of those through the VCU, correct?
Yes, doing that essentially makes the system CAN controlled and the VCU would be fine with it.Actually, Mojave, I'm assuming I can send a CAN signal to an arduino via the VCU, and just have the arduino interpret the CAN message into a PWM signal that drives the A/C compressor... I already have the PWM signal setup to output correctly from an arduino to drive the compressor. I'd just be changing my code logic on the arduino to interpret a CAN message instead of a temperature value from an external sensor. That would in theory let me retain climate control via the vcu, correct? I'm assuming that all interfaces and supports programmable behavior via the carbon display?
I don't think they have announced anything on that but I think its fair to say its in the works. I have no timeline or ETA.Any updates on the sport LDU drive unit board?
Just want to correct something here, the AEM CCS solution WILL consist of an add-on CCS module. The CCS program is ongoing at AEM and no announcement or product is imminent, I just saw this and didn't want to let it hang out there when I knew it was incorrect.They're working on CCS fast charge support, it sounds like it'll be essentially drop-in to their BMS system without needing to buy a special extra module from them or anything
