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

Abstract

The invention relates to a hardware-in-loop testing device and method for a vehicle-mounted battery charger control device of a new-energy automobile. The hardware-in-loop testing device comprises an upper computer testing interface, an LABCAR system, a vehicle-mounted battery charger control unit and a battery management system. The hardware-in-loop testing method comprises the steps that the upper computer testing interface carries out normal function test and abnormal test on the vehicle-mounted battery charger control device and sends test contents to the LABCAR system; the LABCAR system sends electric signals required by the vehicle-mounted battery charger control device and the battery management system according to instructions, collects electric control instructions sent by the vehicle-mounted battery charger control device and the battery management system to carry out closed-loop control and feeds back simulation running results to the upper computer testing interface in real time. The hardware-in-loop testing device and method have the advantages of being capable of carrying out static testing and dynamic testing of normal AC charging functions on the vehicle-mounted battery charger control device and testing whether the vehicle-mounted battery charger control device can identify occurrences of faults and carry out correct fault processing.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to a hardware-in-the-loop testing device and method for a vehicle-mounted charger control device of a new energy vehicle. 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 electric vehicles.

Problems solved by technology

[0003] Therefore, the whole charging process is extremely complicated

If the charging test is carried out in a real state, it consumes energy and cannot simulate faults. If the logic of the software to handle charging faults is unreasonable or incomplete, once abnormal charging occurs, it will cause damage to the entire high-voltage system of the car, and even Will endanger the life safety of personnel
