Embodiment Construction

[0058] Figure 1a The schematic diagram shows an onboard electrical system 2 of a motor vehicle designed as a hybrid or electric vehicle, wherein the onboard electrical system 2 has a plurality of interconnected lines, in particular high-voltage lines, as components. Here, the first branch 46 comprises a plurality of interconnected lines for the positive high voltage (HV+), while the second branch 48 comprises a plurality of interconnected lines for the negative high voltage (HV−). As further components, the vehicle electrical system 2 has a first converter 4 , here an AC-DC converter; a second converter 6 , here a DC-DC converter; and a third converter 8 , here Designed as a DC-AC converter or inverter. An electrical energy store 10 or a corresponding battery, which is here designed as a high-voltage or high-voltage energy store, is connected to the vehicle electrical system 2 . At least one load 12 , for example an electrical device, is connected to vehicle electrical syste...

Abstract

A method for testing a charging process of an electrically powered motor vehicle having an on-board power system (2), wherein the on-board power system (2) includes at least one charge connection (18,20) for connecting the on-board power system (2) to a charging station (22, 24) and is connected to at least one electric power storage device (10), wherein an adapter (26) having at least one discharge connection (30) is additionally connected to the on-board power system (2) for testing the charging process, wherein electric power for testing the charging process is conducted via the at least one charge connection (18, 20) into the on-board power system (2), wherein a primary portion of the electric power is discharged again from the on-board power system (2) via the at least one dischargeconnection (30) of the adapter (26).

Description

technical field [0001] The invention relates to a method and a system for testing the charging process of an electric vehicle. Background technique [0002] Electric vehicles have a traction battery and thus usually a high-voltage energy store for storing electrical energy for driving the electric vehicle. Here, two possibilities are offered for charging such high-voltage energy stores. According to a first possibility, the AC charging is carried out here with a conventional AC voltage and a charging power of, for example, 11 kW. According to a second possibility, DC charging is carried out by means of a DC voltage with a charging power of, for example, 150 kW. The two possibilities of charging require separate protection, verification and release. However, this is a challenge for the latest generation of electric vehicles or battery electric vehicles (BEV, Battery Electric Vehicle) with a range of approximately 500 km, since the charging check can only be carried out wit...
