Hardware-in-loop test device and method for vehicle-mounted charger control device of new energy automobile

Abstract

The invention relates to a hardware-in-loop test device and method for a vehicle-mounted charger control device of a new energy automobile. The device comprises a test upper computer interface, an LABCAR system, the vehicle-mounted charger control device and a battery management system. The test method comprises the steps that a tester conducts normal function test and fault test on alternating current charging through the test upper computer interface, the test upper computer interface sends test content to the LABCAR system through a network cable, and the LABCAR system sends an electrical signal required by the vehicle-mounted charger control device according to an instruction of the tester, collects an electrical control instruction sent by the vehicle-mounted charger control device to conduct closed-loop control, and feeds the electrical control instruction back to the test upper computer interface for fault check. The hardware-in-loop test device and method have the advantages that alternating current function test can be conducted on the vehicle-mounted charger control device, abnormal test and fault simulation can be conducted on the whole alternating current charging process, and whether the vehicle-mounted charger control device can correctly complete fault detection and fault handling is detected.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a new energy vehicle on-board charger control device and a battery management system hardware-in-the-loop testing device and method based on cable-controlled power supply. Background technique [0002] New energy vehicles are one of the main ways to solve the problems of vehicle exhaust pollution and oil energy shortage. However, due to the impact of power battery energy storage density, new energy vehicles cannot reach the level of traditional vehicles in terms of power and cruising range at this stage. , so it is very necessary to charge new energy vehicles externally to meet the driving needs of drivers. Since the charging of new energy vehicles requires the power supply equipment to continuously output large power, the conventional power grid is difficult to meet the charging demand, so a special power supply device, that is, a charging pile, is required to provide a chargi...
