ONBOARD POWER SUPPLY AND METHOD FOR OPERATING AN ONBOARD POWER SUPPLY

摘要

The invention relates to an onboard power supply, comprising: a starter power supply having a high-power load, particularly a starter and a first energy storage, particularly a double-layer capacitor; an intermediate power supply having a second energy storage, particularly a rechargeable lithium polymer battery; a load power supply having at least one electric load, wherein the starter power supply is electrically coupled to the intermediate power supply via a first voltage converter, wherein the intermediate power supply is electrically coupled to the load power supply via a second voltage converter, and the onboard power supply has a controller, which controls or regulates the electric voltage in the intermediate power supply as a function of a parameter of the second energy storage.
