Problems solved by technology

Therefore, the software interface between the two further increases the workload of software development.
[0006] (3) All the data are real-time data, and it is impossible to predict the future development of the on-board power battery, and it is also impossible to simulate and analyze the existing monitoring data, so that the problem of the on-board power battery is often discovered after the on-board power battery is found to be faulty ;
[0007] (4) Before the improvement is made, it is impossible to know whether the improvement method will cause the vehicle power battery to be damaged again, and whether it is suitable for the vehicle power battery;
[0008] (5) The control commands of the on-board power battery are all directly implemented, which is easy to cause misoperation, resulting in damage to the on-board power battery

Abstract

The invention discloses a test system of an electric automobile power system. The test system comprises a man-machine operation module, a brake pedal, a sensor for displacement of the brake pedal, an acceleration / speed sensor, an accelerator mistaken stepping prevention module, a braking force magnitude warning module, a data acquisition module, a central control unit, a power limiting module, a control command preview module, a prediction analysis module, an expert assessment module, a physical model building module, a virtual parameter actuation module, a virtual parameter module and a simulation analysis module. The test system of the electric automobile power system realizes comprehensive acquisition of basic situation data of a vehicle-mounted power battery, and performs prediction of a vehicle-mounted power battery situation and a future development situation through the prediction analysis module; preview of a control command needs to be performed first before confirmation of output of each command, thereby well avoiding an error of control command output, and enabling each control command to have visualized; and simulation analysis of the vehicle-mounted power battery basic situation data and a maintenance plan or emergency measures is realized.

Description

technical field [0001] The invention relates to the field of electric vehicle detection, in particular to a test system for the power system of the electric vehicle. Background technique [0002] The efficiency of electric vehicle transportation depends largely on the power of the vehicle. Power is the most basic and important performance of electric vehicles. The power system of an electric vehicle is generally a variable frequency motor drive system, which consists of a frequency converter and a power motor. For the simulation test of this power system, it is necessary to use an additional load (electric dynamometer) to load the power motor, use a program-controlled external DC power supply to supply power to the power motor, and measure and analyze the power of the power system. The output of the frequency converter and the output of the power motor are measured synchronously to understand the operation and work efficiency of the power equipment during the actual operat...
