Abstract

The invention relates to a method for charging an energy store (14) of a motor vehicle (10) on an external charging device (16) of the motor vehicle, in which at least one charging boundary condition(SOCZ, kmZ, tmin, tmax, KB, EB) specified by a user (20) of the motor vehicle (10) exclusively for an imminent charging process for charging the energy store (14) is determined, a charging current (I)for the imminent charging process is determined as a function of the at least one determined charging boundary condition (SOCZ, kmZ, tmin, tmax, KB, EB), and the charging process is carried out as afunction of the determined charging current (I).

Description

technical field [0001] The invention relates to a method for charging an energy store of a motor vehicle at a charging device external to the motor vehicle. The invention also relates to a control device for controlling a charging process and to a motor vehicle. Background technique [0002] An important aspect in connection with electric vehicles lies above all in the provision of so-called fast charging functions. The challenge here is to charge the energy storage, in particular the HV (high voltage) battery, of such an electric vehicle as quickly as possible without damaging the energy storage. In this case, higher and higher charging powers, for example more than 200 kW, are developed. In principle, therefore, a large amount of energy and thus a driving range can be charged into the high-voltage battery in a short time. [0003] However, it would be desirable to be able to further optimize the charging method for charging the energy store of the motor vehicle. [000...
