摘要：
本发明公开了一种新能源汽车的动力系统测试方法及系统，方法包括：获取动力系统的性能数据；根据性能数据分别计算设计动力性能参数值和实际电力性能参数值；分别提取设计动力功率参数和实际电力功率参数并进行匹配，获取匹配度；当匹配度小于第一阈值时，显示设计动力性能参数值，否则核算实际动力性能参数值，并显示核算的实际动力性能参数值；系统包括数据获取模块、运算模块、匹配模块、核算模块。本发明通过计算设计动力性能参数值和实际电力性能参数值，并设计动力功率参数和实际电力功率参数进行匹配，当匹配符合要求时则显示设计动力性能参数值，否则进行实际动力性能参数值核算，从而提高了动力性能参数值测试的准确性。
摘要（英）：

The invention provides a power system test method and system for a new energy vehicle. The method comprises the steps that the performance data of a power system are acquired; the design dynamic performance parameter value and the actual power performance parameter value are calculated respectively according to the performance data; the design power parameter and the actual power parameter are extracted respectively and are matched to acquire the matching degree; and if the matching degree is less than a first threshold value, the design dynamic performance parameter value is displayed, otherwise the actual dynamic performance parameter value is calculated and displayed. The system comprises a data acquisition module, an operation module, a matching module and an accounting module. According to the invention, the design dynamic performance parameter value and the actual power performance parameter value are calculated; the design power parameter and the actual power parameter are matched; if the matching meets a requirement, the design dynamic performance parameter value is displayed, otherwise the actual dynamic performance parameter value is calculated; and the accuracy of the dynamic performance parameter value test is improved.
