Using multiple chargers for one pack
Question:
I need a 96Vcharger for my LiFePO4 battery pack. Do you have any one ?
Answer:
If you need charging 96 volt pack with 32 cells, you can use sametwo . First charger connect to cell number 1 to cell number 16. And second charger from cell number 17 to number 32 cell.
1 - charger 48V/10A
EVSE PIN setting priority
Question:
What is the PWM output if on pin 4 a voltage is applied to allow 20A AND at the same time pin 5 is shortend to ground (pin 3)?
Answer:
Multiple chargers
How shouldI connectmultiple chargers to charge a battery pack?
Withgalvanically separatedchargers, it is possible to have more chargers to share in charging of the same battery pack. The chargers must be always connected to the battery pack directly.
If possib
