Abstract: An energy consumption decomposition method of an electric vehicle, an analysis method, a system, a device and a medium are provided, relating to the technical field of energy consumption monitoring of an electric vehicle. The energy consumption decomposition method includes: acquiring actual driving data of an electric vehicle to be analyzed during a trip; determining the trip energy consumption rate and driving features of the trip according to the actual driving data, where driving features of the trip are influenced by a trip factor and/or a driving behavior factor; and determining an energy consumption decomposition result of the electric vehicle according to driving features and the trip energy consumption rate, where the energy consumption decomposition result at least includes components of the energy consumption rate corresponding to driving features of the trip.

Abstract: A method and system for characterizing an energy consumption indicator of an electric vehicle (EV) is provided. The method includes performing a cyclic energy consumption test on the EV to acquire a time-speed curve, a time-direct current (DC) energy consumption curve, and a total alternating current (AC) energy consumption in the test cycle. A DC energy consumption rate and an AC energy consumption rate of the EV is determined in each of test sub-cycles. A driving feature is determined in each of the test sub-cycles and a normalized driving feature is determined in each of the test sub-cycles according to the driving feature in each of the test sub-cycles and a base driving feature. A DC energy consumption indicator and an AC energy consumption indicator of the EV are extracted according to DC energy consumption rates, AC energy consumption rates and normalized driving features of the EV in all test sub-cycles.
