Separate names with a comma.
I think that I have proved that the opposite is true. Excessive discharging is unnecessary and damaging. I did not know that. Are you saying that...
The Prolong System advocates excessive discharge and charging. My own testing has confirmed that discharging below 168V is of no benefit. The...
You don't say whether the pack has been charged yet? The whole pack needs to be charged to 224V, at which point all the modules should read 8.0V...
Voltage depression occurs at higher discharge currents, but it is supposed to be insignificant below 1C(6.5A). Obviously discharging at higher...
Finished the battery reconditioning. The full write up I here...
Before suspecting the HV battery, check the condition of the air filter and the auxiliary 12V battery.
I just wanted to show that "less is more" when it comes to battery reconditioning. It's easy to over do it and there are plenty of examples online...
Synopsis The goal was to find a method to quickly restore capacity without degrading the battery life in my 2007 Prius Gen 2 traction battery....
Just finished cleaning the bus bars on my 2007 Gen2, see the before and after pictures below... [ATTACH] [ATTACH] [ATTACH] I found that the...
Expect to replace the 12v battery every five years. The car won't start without it. It should have a date of manufacture on it, so you can check...
Thanks for the info. I assume that you were discharging one module at a time. The first cycle discharge value (134V) for the Prolong system is...
Why is each discharge time shorter than the previous one? Doesn't that imply that the total battery capacity is decreasing not increasing?
I see the value of the Prolong System, I just don't see the necessity of discharging the lowest capacity cells to 0V and risking those cells...
So you are saying the current from adjacent cells that are still discharging will not cause polarity reversal in a cell at 0V, but self discharge...
Individual NiMH cells can be discharged to zero volts and so can multiple cells in series, provided that the capacity of the cells are closely...
The LPC-150-500 is 500mA constant current supply, with an output voltage swing of 150 - 300V DC. The voltage spec is very similar to the...
I've ordered a LPC-150-500 so that I can DIY my own full pack charger. Planning to balance the pack out of the car so that I can monitor...
Your experience implies that when discharging the pack as a whole, it would be best to monitor the voltage of individual modules and stop the...
I can see that because the pack operates over a restricted range of SOC (40 - 80%), the pack can tolerate modules with varying capacities....
Cells or modules with the same SOC but different capacities will take differing amounts of time to discharge at a constant current. The only way...
