Not sure if this is true for all of the trucks, or if there is something wrong with mine, but if I pull the high voltage disconnect and the 12 volt accessory battery, my truck simply starts over, regardless of the State of Charge on the batteries. After a disconnect, it has to...

So we hooked up our 26 PbA batteries today and the contactors closed for a few seconds and then opened up again (no big surprise). Now we begin the task of clearing the error codes and pleading with the BMS to accept the new batteries. If we had a DBC file we might even be abl...

Thanks Gil, The red and black wires to the fan now run *directly* between the fan and the battery - the power wiring through the 25-pin connectors is now bypassed. The control wire is still using its original wiring. I have added a pair of wires (one fused) connected directly...

It would be my post below. The SOC will adjust for low modules but you should not have that problem with a good pack of lithium. As long as the modules are holding up and staying in balance all the BMS will track amps in and out. Ideal would be modules that can balance themsel...

Hello Naiche Yes and no. To do it correctly would take reprogramming the truck for a different chemistry. The only one that could do that would be GM. The truck will track amps in and out so that will give a SOC you can use. If the truck SOC works by only counting amps it will...

Negative delta V applies to the nickel chemistries (NiCd, NiMH). Not Lead (or any others that I'm aware of). It is especially apparent in NiCd. Less so in NiMH. At the end of charge, Nickel chemistries actually show a very slight DROP in voltage. (It's *very* slight in compari...

Hello Steve Yes hard to believe you could get 300,000 cycles considering the added heat at top of charge. You would think that alone would reduce a lot of cycle life. You would have to factor in calendar life as well. At some point age is going take its toll. However if you ke...

Don, I took the graph you referenced and multiplied the cycle number by the mileage of a full cycle. I used 70 miles when new. I didn't factor the loss over time so the real numbers would be less than calculated. but here are the numbers: 100% DOD = 70 miles x 700 cycles = 49,...

I was wondering about what it would take for a lithium ion upgrade. Would it require using a kWh gauge to measure the SOC? I've seen a few out there on the market. Wouldn't the S10 firmware need to be updated to be able to properly read the SOC of a different type of pack? On...
