Research Of Electric Commercial Vehicle Development Base On Traditional Chassis

The electric vehicle commercial vehicle development process based on the traditional chassis is based on the traditional commercial vehicle development process,the process of matching traditional fuel engine development and matching with the traditional commercial vehicle second-class chassis into pure electric power.The system undergoes matching calculation and selection,and is equipped with the entire vehicle for test verification.The development process of pure electric commercial vehicle is based on the quality management system of each vehicle company,and the development process of pure electric van transporter is detailed to ensure that the developed pure electric van transporter can meet Expected indicators of the project,user needs and expectations derived from analysis of market research results,and relevant laws and regulations.In order to meet the power economy performance level of the entire vehicle,according to the performance indicators defined by the entire vehicle product,it is necessary to perform matching calculations on the power drive system and to match the mature products of the manufacturer for matching selection.Combine MATLAB and dynamic simulation software to perform dynamic and economic simulation to verify the accuracy of selection.Because the original traditional power drive system,transmission system,engine mount and other systems are replaced.Match pure electric drive motor,motor controller,high-voltage power distribution box,fast and slow charging system and tube circuit,and replace the drive axle that matches the drive motor.The vehicle has changed in terms of maintenance and total mass,and front and rear axle loads..The braking performance of the entire vehicle needs to be selected and calculated to ensure the vehicle’s safety.Finally,the prototype and small batch loading are used to verify the physical integration and general layout scheme.Through the vehicle’s power economy test and reliable durability test,the power system matching results at the research and development stage are verified to complete the vehicle development verification.
