As we are talking about the Battery ECU, you might find my teardown and analysis post interesting.
Pretty cool. I wonder what it's going to cost?
For reference, Here is the simplified schematic of it's wiring in the Prius: [IMG]
Here is a link to my Battery ECU teardown in case anyone is curious.
I'm presently working on an outright replacement for Toyota's Battery ECU for my PHEV project. I'm sure others are also curious, so here's my...
I'm replacing the battery ECU with one of my own design. It's the last device on the CAN bus, so it can talk to any of the other CAN nodes in...
Here's the Layout: [IMG]
Yeah the heater works amazingly well, and uses so little. (it's German) I think I can make it through a whole winter on about 2 gallons of...
Ok, so I'll bite; what's "ScanCan"? :)
Oh, and if you replace it and it fixes the problem, I'd love to do an expert teardown and failure analysis of the original one, maybe I can...
The shifter mechanism in the Gen2 is hall-effect, which means the electrical switches themselves have no moving parts and instead respond to a...
Ok, if you build your own inverters (you'd need 2), then maybe you have something. The existing drive in EV is limited mostly by what the boost...
So maybe the solution is to fully block the top slats on the front as is being done, (maybe this helps Aero?) partially the lower, then add a...
Yeah, it's monopolistic behavior to be sure. I almost think that the reason for all the "security" isn't really to prevent our cars from being...
Personally, I think that's a bad way to go. You'd be much better off replacing the complex Prius transaxle with a single electric motor. From...
[media] All kidding aside with that one, Are you intending on replacing the whole transaxle? If not, You'd have to do extensive mechanical...
Here's a page you can add, I've annotated the connections on the Battery ECU: [IMG]
Nice trick disconnecting the Parking Actuator. Another good one would be to disconnect the brake signal so the car will not shift in the first place.
Thanks Vertex! I am currently working on reverse-engineering the Battery ECU, so I will likely be able to contribute some detailed info on it at...
Oh! I see you created a new thread with the teardown document. Nothing else to see here then, move along!
