Hardware-in-the-loop test method for on-board charger control device of new energy vehicles

Abstract

The invention relates to a hardware-in-the-loop testing method for a vehicle-mounted charger control device of a new energy vehicle, comprising: a tester performs a normal function test and a fault test of AC charging through a test host computer interface, and the test host computer interface sends the test content to LABCAR system, the LABCAR system sends the electrical signals required by the on-board charger control device according to the tester's instructions, and collects back the electrical control commands sent by the on-board charger control device for closed-loop control, and at the same time feeds back to the test host computer interface for fault checking. The beneficial effects of the present invention are: the present invention can carry out the AC charging function test on the control device of the on-board charger, and can also carry out abnormal testing and fault simulation on the entire AC charging process, to detect whether the control device of the on-board charger can correctly complete the fault detection and Troubleshooting.

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 method based on an on-cable control power supply mode. 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 charging ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new energy vehicle on-board charger control device and battery management system hardware-in-the-loop test equipment and test method to overcome the long test period and large test power consumption of the existing AC charging test technology and method , and it is impossible to perform fault simulation on the AC charging process. Once an abnormality occurs during the charging process, it will cause damage to the vehicle, so as to overcome the above-mentioned shortcomings in the existing technology
