1. , for from the AC electric power system method to high-tension battery power charge, it is characterized by following characteristics:

  • -this high-tension battery is connected to this AC electric power system by means of a charging device (OBC), and this charging device includes manyIndividual Voltage rails (L1, L2, L3), wherein, each Voltage rails (L1, L2, L3) is all assigned with a filter capacitor (Cy),-calculate the highest possible charge power of this AC electric power system,-in these Voltage rails (L1, L2, L3), select at least one Voltage rails (L1, L2, L3), this at least one Voltage rails pairIt is non-essential in the charge power being computed, and-turn off the filter capacitor (Cy) being assigned to non-essential Voltage rails (L1, L2, L3).
