Hardware-in-the-loop test equipment and method for off-vehicle DC charging control device

Abstract

The invention relates to a hardware-in-loop testing device for a new energy vehicle non-vehicle-mounted direct-current charging control device. The hardware-in-loop testing device comprises a testing upper computer interface, an LABCAR system, the non-vehicle-mounted direct-current charging control device and a battery management system. The LABCAR system comprises a programmable power supply, a real-time simulation computer, a resistance signal simulation board card, a bus signal simulation board card, a fault simulation board card and a digital signal simulation board card. The hardware-in-loop testing device and method have the advantages that static testing and dynamic testing can be performed on direct-current charging normal functions of the non-vehicle-mounted direct-current charging control device and the battery management system, besides, faults of the whole direct-current charging process can be simulated, then under the condition that the faults occur, whether the non-vehicle-mounted direct-current charging control device and the battery management system can identify occurring of the faults or not is tested, and the faults are correctly processed.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a new energy vehicle off-vehicle DC charging control device and a battery management system hardware-in-the-loop testing equipment and testing method. 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 interface for elec...
