Method and apparatus for power management of an electric drive for a hybrid vehicle

摘要

The invention relates to a method and a device for power management of an electrical drive for a hybrid vehicle, wherein the method comprises the following steps: detecting (S1) an adjustable power requirement for the electrical drive device and an available electrical battery capacity of the electrical energy store by means of a detecting unit (21); comparing (S2) the detected adjustable power requirement to the detected available electrical battery capacity by means of a control unit (22); and deactivating (S3) at least one of the electrical consumers in dependence on criteria specified by the control unit for one or a plurality of specified time intervals by the control unit (22), if the comparison results in a lower available electrical battery capacity than the adjustable power requirement.

1. A method for power management of an electric drive device of a hybrid vehicle comprising electrical consumers and an electrical energy store, wherein the method comprises the following steps:
detecting (S1), by a detection unit (21), a power demand for the electric drive device and an available electric battery power of the electrical energy store; comparing (S2), by a control unit (22), the detected power demand with the detected available electric battery power; and disconnecting (S3) at least one of the electrical consumers based on a criteria predetermined by the control unit (22) for one or more fixed time intervals by the control unit (22) when the comparison indicates a lower available electric battery power than the power demand; and wherein, after disconnection (S3) of an electrical consumer, for a fixed time interval, electrical power is made available to the electrical consumer again once the fixed time interval for a fixed switch-on time interval has elapsed.
