Honda Accord Hybrid PHEV conversion possible?
Submitted by MagnumEV on Sun, 04/22/2007 - 12:10.
Hello,
My father has a honda accord hybrid and was curious to know if there are conversion kits out there for them. i know that they make them for the toyota prius and ford ranger but what about honda? Or are there any home made ways to do this? i assume not because of all the computers and circuitry inside but you never know. I have been telling him he should just sell it and get a full electric but he has to go on trips acrossed the state occasionally so that might not work.

Re: Honda Accord Hybrid PHEV conversion possible?
I'm not aware of any plug-in conversions for Hondas.
I own a Civic Hybrid and I also got the factory service manual with about as much wiring information as they will give out. Adding additional batteries could be done in a manner similar to a Prius, and charging from the grid is no problem.
The problem would be to reprogram the IMA computer to take advantage of the extra stored juice. All communication between the IMA and the main engine computer is by CAN, a type of serial interface protocol. There are readers that can look at the stream, but making sense of it might be pretty difficult without some insider information.
I once had a recall on the IMA program and they uploaded new software, so I know that could be done. Getting a programmer and figuring out the code would be the hard part.
Another approach I thought of would be to intercept the line that goes between the main ECU and the IMA computer and come up with a PIC that could "spoof" the throttle position information to fool the IMA into giving more juice to the electric motor, as happens when you step on the accelerator.
I'm just waiting for the warranty to run out before I do any serious hacking.
