Abstract

The invention discloses a hardware-in-loop test system of a battery charger. The system comprises an electric power system simulator and a power amplifier; the electric power system simulator is used for simulating an electric power system according to an electric power model of the electric power system and generating a simulation power grid signal, wherein the simulation power grid signal is an electric power signal outputted according to the electric power model; the power amplifier is connected with the electric power system simulator and the battery charger, and is used for executing power amplification according to the simulation power grid signal and producing a test voltage same with the power level of the battery charger, wherein the battery charger is used for executing a function test according to the test voltage. Due to the hardware-in-loop test system of the battery charger, the problem in the related technologies that a hardware-in-loop test method cannot execute a function test of a complete machine after the battery charger is switched in the electric power system is solved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a hardware-in-the-loop test system of a charger. Background technique [0002] The charger can be connected to the power system, and use the electric energy of the power system to charge and discharge the power electronic equipment. For example, after the electric vehicle is connected to the grid through the charger, the charger can charge the battery of the electric vehicle through the power provided by the grid. Alternatively, it is also possible to discharge the battery of the electric vehicle and feed the energy back to the grid. As the number of electric vehicles increases, the mutual influence of electric vehicles after they are connected to the grid will also deepen. ), are the hotspots and key issues of current research. The charger is a bridge for electric energy circulation between electric vehicles and the grid, and it is also an important component in the process of re...
