Abstract

The invention discloses a comprehensive efficiency quantitative test and calculation method for an automobile electric energy system. The steps include: firstly determining the set of cycle working conditions, experimental constant parameters, test times, and load demand power in the vehicle environment; The load demand power in the set is tested in a cyclic working condition, and the data at the sampling time of each test is recorded to obtain the total sampling set; the coarse error is eliminated and the optimized data processing algorithm is used for data processing through the Raida criterion, and the corrected test result is obtained. The set of test values; the corrected test value is substituted into the average efficiency calculation formula of the vehicle composite power supply system for calculation, and the average efficiency of the composite power supply system is obtained. The invention makes the average efficiency of the test more accurate, evaluates the comparison of the average efficiency of the test vehicle under different demand powers, and can provide certain data support for the optimization and improvement of the related control strategies of the subsequent composite power supply system, so as to achieve the purpose of optimizing energy management and control .
