Device for energy supply to hybrid motor vehicle has performance optimized energy storage device and second performance-optimized energy storage device whereby charge controller adjusts scheduled charge state of first energy storage

Apparatus (10) for supplying power to a hybrid vehicle having a first power-optimized energy storage (26) and a second energy-optimized energy storage (28) and a a target state of charge (QA) of the first energy storage device (26) adjusting the charge controller. The invention further relates to a corresponding method for power flow control in a hybrid vehicle having a first energy store (26) and a second energy store (28) wherein the target state of charge of the first energy storage device (26) with increasing speed (v) of the hybrid vehicle is reduced.
