Description

Technical Field

[0001] The utility model relates to the technical field of energy consumption management of new energy vehicles, and in particular to an energy consumption monitor for a three-phase induction motor of a new energy vehicle. Background Art

[0002] The application prospects of new energy vehicles are very broad, but there are also problems such as low energy density and short service life of power batteries. In addition to being related to the battery module, the performance of power batteries is also closely related to the energy consumption of the entire vehicle. Especially under the condition that the quality of the battery module is not ideal, the role that energy consumption detection can play is more obvious. At present, the existing vehicle energy consumption test method can only measure the theoretical energy consumption and energy saving rate, and the accuracy of the test results is extremely low. Thus, the true meaning of vehicle energy consumption testing is lost. And due to the complexity of the energy consumption structure of pure electric vehicles, it is difficult to accurately express the energy consumption status and energy saving status by measuring the power consumption with a single indicator (SOC). Chinese domestic regulations use the working condition method and the constant speed method to test and evaluate energy consumption. The United States has improved the traditional working condition method, called the EPA five-condition method, including typical urban working conditions, typical high-speed working conditions, aggressive driving working conditions, cold start working conditions and air conditioning test working conditions. Although these working conditions relatively comprehensively reflect the energy consumption level of electric vehicles, since the actual driving working conditions are almost not completely consistent with any test working conditions, this test method can only roughly predict the energy consumption under different driving conditions, and cannot test the actual driving process.
