Method for operating electrical drive train of vehicle, involves controlling charging state of electrical energy storage by control unit between lower charging state limit and upper charging state limit

摘要

#CMT# #/CMT# The method involves controlling a charging state of an electrical energy storage (40) by a control unit (60) between a lower charging state limit and an upper charging state limit. The upper charging state limit is determined by a variable parameter of the vehicle. The area of the electrical drive train takes place in a voltage area of the electrical energy storage which is determined by the lower- and upper charging state limits. #CMT# : #/CMT# An independent claim is included for a device for operating an electrical drive train of a vehicle. #CMT#USE : #/CMT# Method for operating an electrical drive train of a vehicle. #CMT#ADVANTAGE : #/CMT# The method involves controlling a charging state of an electrical energy storage by a control unit between a lower charging state limit and an upper charging state limit, and thus ensures improved operating method for the drive train with optimized efficiency. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an operating device. 5 : Electrical drive train 10,15 : Electrical machines 25 : Internal combustion engine 40 : Energy storage 60 : Control unit.
