Electric Vehicle Motor Controller Design

An electric motor converts electric energy into mechanical energy while an electric generator converts mechanical kinetic energy into electrical energy.

Electric vehicle motor controller design.

The vehicle can run as long distance as possible. Let s assume that the battery pack contains 12 12 volt batteries wired in series to create 144 volts. Figure 3 shows the state flow chart of vehicle control logic which in addition to shutdown mode the other state containing the. 200kw ac motor controller for electric car.

Electric vehicles are not something new to this world but with the technological advancement and increased concern on controlling pollution has given it a tag of future mobility. So that users drive vehicle only thorough the tps eps and vehicle stop switch. The core element of the ev apart from electric vehicle batteries which replaces the internal combustion engines is an electric motor the rapid development in the field of power electronics and control techniques. But for pure electric vehicle motor is the single power source the vehicle can only depend on motor running to leave dangerous area even motor drive system meet big failure suddenly otherwise the passenger will be stranded in any possible dangerous area such as high way hungriness etc.

Compared to an internal combustion engine an electric motor has several advantages. We have a dedicated team of functional safety consultants and engineers. However they are still pretty expensive. A java web application software is developed for a dc motor position.

The design and development of this motor controller for electric vehicle adheres to the guidelines of the iso 26262 standard for functional safety in automotive. A 3 phase ac motor is the absolute standard for car companies when they make an electric vehicle. 2 2 software design 2 2 1 vehicle control logic in this research the motor controller integrates vehicle control function 4. The controller s job in a dc electric car is easy to understand.

Based on the technical requirements of hybrid electric vehicle motor controller introduce the special purpose chip of motor control of microchip corporation s dspic33fj128mc706 to be the controller core and according to the pulse width modulation signal of voltage of asynchronous induction motor generated by the manner of space vector. Electric cars are the future and are beginning to take off today. An electric machine can be of two types. The controller takes in 144 volts dc and delivers it to the motor in a controlled way.
