Energy consumption measuring system and measuring method for electric vehicle

Abstract

The invention discloses an energy consumption measuring system for an electric vehicle. The energy consumption measuring system for the electric vehicle comprises a battery measuring module, a vehicleweight module, a motor measuring module, a motor controller measuring module, a VCU measuring module and a calculating module, wherein, the battery measuring module is used for measuring current andvoltage at the output end of a battery, the motor measuring module is used for measuring the current and the voltage at the input end of a motor, the motor controller measuring module is used for measuring the current and the voltage at the input end of an electric motor controller, the VCU measuring module is used for measuring rotating speed and torque of the motor when driving, the vehicle weight module is used for simulating the measurement results of the battery measuring module, the motor measuring module, the motor controller measuring module and the VCU measuring module by carrying outweight balancing at different positions of the vehicle. The energy consumption measuring system and measuring method for the electric vehicle are closer to the actual use state of the electric vehicle, so as to make a more effective analysis on energy consumption and the efficiency of the whole vehicle of the electric vehicle and ensure that the data accuracy and authenticity of the measurement system.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to an energy consumption measurement system and a measurement method of an electric vehicle. Background technique [0002] With the rapid development of the global economy, the consumption of oil is increasing day by day. As a non-renewable resource, oil is becoming increasingly scarce. Traditional automobiles are used as the main means of transportation in cities, such as public transport vehicles, taxis, etc., which run repeatedly in the city, which not only consumes a lot of oil resources, but also affects the sustainable development of the environment due to the exhaust gas they emit. Therefore, electric vehicles as an alternative means of transportation for traditional fuel vehicles are no longer a new topic, and they are getting more and more attention from the government and people. Similarly, although they use electric energy, the energy consumption of electric ...

Problems solved by technology

However, during the road test of this type of system, only the road tester drives the electric vehicle alone, which cannot be compared with the energy consumption of the vehicle when there are many people or loads in the actual use of the vehicle, and cannot provide potential consumers with intuitive energy consumption. data
