Electrical power supply for electrical car and hybrid car, has secondary circuit inductively attached to primary circuit, and internal voltage sources or voltage sinks and external voltage sources or -sinks attached to secondary circuit

摘要

The supply has a high volt battery comprising battery cells (BZ1) connected in series. Inductors (L1-Lm) with switches (S1-Sn) are arranged parallel to the individual battery cells to form a primary circuit. A secondary circuit is inductively coupled for adjusting cell voltages of the battery cells. The secondary circuit is inductively attached to the primary circuit. Internal voltage sources or internal voltage sinks are attached to the secondary circuit. External voltage sources or external voltage sinks are connected to the secondary circuit. The battery cells lithium-ion-battery cells or double layer capacitors.
