Hello All,
my name is Jiri, coming from Europe, my occupation is a teacher/researcher on university, I am dealing with electrochemistry, especially with li-ion batteries.
I would say I have got a knowledge in batteries topic, electrode materials, electrolytes ....just basic research. Unfortunately i have zero practical experience. I decide to star building my own battery boxes for electric vehicles and that is the reason why I sing in to this board.
May I ask you about battery voltage in the pack?
Lets assume that I am using only 3.6 V cells (nominal working voltage) charged to 4.1 V, the difference is 0.5 V per cell.
How many cells in series I need to build up the packs with these nominal voltages:
24 V nominal = 6s or 7s ?
36 V = 10s
48 V =13s or 14s ?
If the nominal voltage of the batt. pack is for example 36 V and we have 10s the charger must reach charging voltage 41 V, am I right?
Thank you for not so cleaver question but I am confused about it.
Thank you,
Jiri
