New energy vehicle on-board charger control device hardware-in-the-loop testing equipment and method

Abstract

The invention relates to a hardware-in-the-loop test equipment and method for a vehicle-mounted charger control device of a new energy vehicle. The in-the-loop test equipment includes a test host computer interface, a LABCAR system, a vehicle-mounted charger control unit, and a battery management system; the in-the-loop test method includes testing The host computer interface conducts the normal function test and abnormal test of the on-board charger control device, and sends the test content to the LABCAR system. The LABCAR system sends the on-board charger control device and the electrical signals required by the battery management system according to the instructions, and collects them back to the on-board charger control. The electrical control commands issued by the device and the battery management system are closed-loop controlled, and the simulation results are fed back to the host computer test interface in real time. The beneficial effect of the present invention is: to carry out the static test and the dynamic test of the normal function of AC charging to the control device of the vehicle charger; to test whether the control device of the vehicle charger can identify the occurrence of a fault and make correct fault treatment.

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
