You need to give us a little more to work on
Yes I have checked each battery after doing a balancing charge and kept a recorded of each charge I have tried to attach a copy of the file but it seems excel files aren't allowed the voltages are between 3.339v - 3.385vLike Duncan says, more info.
After charging, 1 hour or 10 hours latter have you checked the voltage on each battery?
Just to check the BMS
Are you using a dc-dc inverter? is it pulling down the pack or partial?
Do you have a pre-charge resistor on the contactor? sucking battery voltage.
You seem to have problems with even very basic conversion details. Maybe you should stop and start over by showing us photos of the components of the conversion and how they're put together. Or, at least, list the parts and how they're put together. For example the motor, adapter plate, clutch, coupling ,transmission, drive line, final drive ratio. connectors, etc. wire size, Maybe I missed these details. Do you have a build thread on this forum or others?I have finished my 1994 Ford Ranger pickup and have taken it out on several road test it works fine at speeds around town but on the highway it is extremely hard to get it up to 50 mph. There is another problem too it seems to be run down the batteries (even at low speeds) in the first battery box more than the other batteries in the other battery boxes the voltage on those batteries is lower than the batteries in the other boxes. I have Lithium Ion CALB 100ah batteries and a BMS system a Soliton Jr. controller with a Warp11 motor. I have wrecked three batteries just test driving around and can't afford many more test drives at this pace. I can't figure what is wrong with my build and am tired of going around in circles and never getting any closer to solving the problem. I don't know if I got a bad batch of batteries or I did something else wrong the BMS system alarms when a battery's voltage gets around 2.65 or so at least that part works right but what causes that to happen?
I have no idea why you would say that as soon as I can get to your response I will post all of the information I can. I have tried to attach documents and pictures but always get the same error message wrong file type why?I responded to the other thread on the same problem. I suspect I am going to regret that...
Configured correctly, Soliton controllers will limit the amount of motor current when the pack voltage declines too much, and that is the most likely explanation for why your acceleration is so poor, but I'd need to see a log file and your settings to confirm that.... I checked the battery pack with a volt meter and it showed 133v out of 144v system. One battery BMS was blinking so assumed it was the problem and checked it voltage and it was 2.68v...
I made a garage post of my truck and included as many pictures as I could with most of the information I knowYou need to give us a little more to work on
