Also, the harder part is to find and afford a current sensor that can measure all the way to 2000A. I have not looked into this yet, but I was thinking I could build a circuit that would measure 2 current sensors and create 1 output for the controller. It would also interrupt the gate signal to the drivers and use lockout to balance the current between the 2 controllers if it gets out of hand. Again, this is all in my head.

I like your reasoning 2000A would be monstrous for me but not for your vette jealousy is overcoming me now hehe..

It would be really interesting to be beta tester what is involved ?

Please keep the info flowing you just have to keep it evolving Thanks again.

Hi Adam,

Could you tell me if Paul's Melexis HB current sensor PCB would be compatible with your controller ????

Current Sensor PCB

1000 amp test range

Thanks

He's an artist! What artist is going to make 99% of his creation, and then stick someone elses crap inside it for the last little bit? ALSO, the current sensor needs to be calibrated for given bus bar dimensions. A LEM would definitely be less fuss.

It seems to make more sense (no pun) to mount a small Hall sensor (Melexis - MLX91205HB) PCB flat on busbar.

The ring shaped sensor (HTFS-800p) with a connector and power conditioning circuit on a PCB sound like a lot more hardware than needed.

Yes, he would have to calibrate the height the hall sensor PCB on his busbar by shimming its height, but that still seams a lot easier.

If you can find room to mount the surface mount sensor, you can use it, but if i remember correctly, it become impractical because it needs to be so far away from a bus bar wide enough for 2000A.

But in short, yes you can use it if you want to. There will be an option to enter the amps/volt into the controller so it knows what range it can measure.

For a 1 inch wide bus bar that is 1/4" thick, a 1/8" thick PCB (that acts both as the spacer and board you solder the chip to) gives a range of about -1200, to 1200amp. So, you would need another 1/8" spacer to get close to 2400amp. That's only for the Melexis HB, though. The LB needs probably 1.5" or something ridiculous.

I would like to purchase one of your initial protos for testing. If things go well, I would like to purchase two more for another project.

It will be used on a CR125 dirt bike conversion, powered by A123 cells.

I have experience with surface-mount soldering, so a box of parts would be fine with me.

Hi Adam, how is it going any news still waiting impatiently for the good results/news.
Wishing every one here a Merry Christmas and a happy new year

Work has slowed down to a crawl on the controller for the time being.

Ive had to dedicate all my time to a work project with a super tight deadline. I will have to get going on the controller soon though as there seems to be alot of interest lately.

Sorry Everyone.

Adam,
at the risk of asking a stupid newbie question, is this a different controller to the one on your evvette site? I'm guessing that this is something new since the purposed specs in the thread are much better than the specs on the web site. Are you planning on selling this as a kit like the Cougar or a complete controller or both?
