Hi Arcicorsa,
You still listening to this old thread?
I am wondering what the board inside the Spark charging hub does. From what you found out I‘d say the power supply provides a constant 13.05V. Current limiting must be done in the charging hub as per your experiment the battery doesn‘t limit the current. Instead it only detects overcurrent. So is this a correct summary:
-power supply‘s job is to provide a constant and stable 13.05V
- charging hub does the current limiting to 2.5A on each slot
- battery does the balancing and parameter checking (temp, current, voltage min/max)
Do you know what protocol is spoken throught the D+/D- ports. And do those ports correspond to the outer most pins of the battery connector? I reckon this is how the battery exchanges information about temp, cell voltages, total voltage etc with the charging hub and Spark. Am I right?
Thanks,
Michael |
