Abstract
The paper describes the process and results of the development of the light commercial electric vehicle. In order to ensure maximum energy efficiency of the developed vehicle the key parameters of the original electric motor. The article also presents the results of power electronic thermal calculation. For the mathematical model of the vehicle, the driving cycle parameters of the electric platform were determined in accordance with UNECE Regulations No 83, 84. The driving cycle was characterized by four successive urban and suburban cycles. The mathematical model also takes into account the time phases of the cycle, which include idling, vehicle idling, acceleration, constant speed movement, deceleration, etc. The model of the electric part of the vehicle was developed using MatLab-Simulink (SimPowerSystems library) in addition to the mechanical part of the electric car. The electric part included the asynchronous electric motor, the motor control system and the inverter. This model at the output allows to obtain such characteristics of the electric motor as currents, flows and voltages of the stator and rotor in a fixed and rotating coordinate systems, electromagnetic moment, angular speed of rotation of the motor shaft. The developed model allowed to calculate and evaluate the performance parameters of the electric vehicle. Technical solutions of the electric vehicle design were verified by conducting strength calculations. In conclusion, the results of field tests of a commercial electric vehicle are presented.
Highlights
Road transport electrification is currently one of the main trends in the development of the global automotive industry (Along with the trends of increasing autonomy, shared use and inclusion in the information environment) [1]
Despite the fact that in 2015 the share of electric vehicles in the global fleet was insignificant – about 0.1 %, according to forecasts, this share will grow rapidly and will be about 10 % by 2030 and about 40 % by 2050 [2]
Because of the barriers listed above, electric vehicle developers face an important and timeconsuming task. It is to develop an energy-efficient electric drive system. This problem can be solved by an integrated approach to modeling the key components of the electric drive, the development of an adequate mathematical model of the electric car
Summary
Road transport electrification is currently one of the main trends in the development of the global automotive industry (Along with the trends of increasing autonomy, shared use and inclusion in the information environment) [1]. Because of the barriers listed above, electric vehicle developers face an important and timeconsuming task It is to develop an energy-efficient electric drive system. The energy efficiency of the electric vehicle as a whole will depend on how optimally the electric motor was selected. For this purpose, it was decided to develop an original electric motor for the developed electric platform. It was decided to develop an original electric motor for the developed electric platform As it is known, the mechanical characteristic of the motor has two distinct zones: a constant torque zone and a constant power zone. At the initial stage of the motor design the optimal configuration of the rotor and stator slots were determined (Fig. 3)
