Abstract

The invention provides a hardware-in-the-loop test system for a two-way vehicle-mounted charger and test equipment, and relates to the technical field of electric vehicles. The hardware-in-the-loop test system for the two-way vehicle-mounted charger includes: a real-time industrial control computer; a CAN board connected with the real-time industrial control computer via a PCI bus; an FPGA board connected to the real-time industrial control computer through a PCI bus; a D / A board connected to the real-time industrial control computer through a PCI bus; and an I / O board connected to the real-time industrial control computer through a PCI bus. The whole system is controlled through the real-time industrial control computer simulating a whole vehicle controller, sends a test command to a charger controller through the CAN board, simulates the two-way vehicle-mounted charger through the FPGA board, and simulates the CC signal and the CP signal through the D / A board and I / O board, thereby completing the vehicle test and shortening the test cycle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a hardware-in-the-loop testing system and testing equipment for a bidirectional vehicle charger. Background technique [0002] At present, electric vehicles are used as mobile power sources. Before the on-board charger is tested for the whole vehicle, the performance and fault handling mechanism of the two-way on-board charger need to be tested. Generally, a bench test is used, that is, through the AC and DC power supply and the electronic load connection. Two-way on-board chargers are used for testing, but this test method has certain risks in functional verification, cannot perform fault injection tests, and consumes energy; if manual testing is used, the test period will be longer. [0003] Therefore, there is an urgent need for a hardware-in-the-loop test system and test equipment for a bidirectional on-board charger, which can solve the problem that failure testing...
