Ebike Battery Pack Calculator

[crea2k]

Iv been putting this together today at work when I get a spare min, its written in html and jquery and calculates all kinds of battery pack info. Take a look and let me know what you think, and any extra info that might be useful to add in there. Its only setup to work with lipo packs at the moment, so id have to add other chemistries in there, so that the different cell voltages for it to make sense. I thought it would be useful for people setting up controllers and stuff as I know with my adaptto you need to know all the watt hour and amp hour etc and all the voltages, to set it up, so thought this would be easy as you can just input the info and it does all the calculations for you.

That looks like a nifty tool

It would be useful if the LVC/HVC voltages per cell (the part at the end here:

Battery Cell Max Voltage :
4.20 Volts 
Battery Cell Discharged Voltage :
3.60 Volts
Battery Cell Critical Voltage :
3.00 Volts

were either manually enterable or pickable from a dropdown list (or both) of common ones, listed along with their chemistry. Or even just a dropdown of which chemistry, and it would use preset values for that.

Then the calculator could be used for something besides just RC LiPo and similar cells.

Ah cool thanks, thats a good point, I will change that, so it can be used for others then

Good to use along with this one when building
