I started this to unclog another thread and have moved the info here.
This gave us a clue someone was using a BCM fooler style 10k resistor matrix with NIMH to bypass imbalance detection.I created an equalizer box that uses 10k resistors to simulate the voltage signal that IMA computer gets. If it reads all equal voltage, the IMA light stays off. You need a spare battery loom to get the plug that connects to IMA module. Works great for me. Been using it for 6 years.
TOPT RepliesDo you mean you are using a resistor matrix to simulate perfectly balanced sticks with a NIMH pack,
defeating the cars ability to detect imbalance?
Meaning cells can be over or undercharged and reversed without protection?
Do you still have ptc strips fitted?
Can you post details on here in a separate thread please so we can see what you're doing?
First concerns raised.Yes, defeated factory balance safeguards, but kept all the temp sensing.
Interesting experiment, but given the long history of NiMH failure modes and the series configuration of the cells, maybe not too promising. Detecting those voltage differences between the stick pairs is one of the built in battery safety measures Honda designed into the pack. Defeating that will leave safety shutdowns to the next line of defense, which I suppose would be the PTC circuit, assuming it is installed. Interesting to see it tried - just not on my car
Been driving that way for 6 years, so I certainly swear by it. Would I sell it to layman? No way! But for diy who can smell when battery is stinky, and knows how to drive it to keep battery charged it's the greatest!
Also, it's only to get more use out of batteries that are no good.
