DESCRIPTION
The “AEL-EHV” application basically consists of three modules:
From the functional point of view of this application, it is important to note that for the study of the hybrid vehicle, the combustion engine is simulated by means of a servo motor because of the advantages that this involves: the dimensions of the equipment are much smaller and it can also be used inside any laboratory or classroom as it does not produce emissions.
With this application the user can easily assemble the main parts of the electric vehicle such as the combustion engine, the frequency controller with regeneration system and the electric traction motor with the capacity to regenerate energy in situations of braking or downhill. Because it is the user who assembles each of the configurations, the learning and knowledge acquired with this application goes far beyond the basics. The application includes an electrical analyzer that, among many other parameters, show the electrical power flows from the battery to the electric motor (traction mode) or from the electric motor to the battery (regenerative braking mode).
Apart from the elements already mentioned, in order to study the behavior of EVs in depth, it is essential to have a system that can simulate the terrain’s orography. This makes it possible to recreate in the laboratory real situations faced by a vehicle. These situations can be summarized as acceleration, braking and up and down ramps. Each of these situations can be realistically studied thanks to the servomotor coupled to the shaft of the main electric traction motor. The servomotor receives the commands from a servo-driver, a device included in this application that will control the servomotor dynamics to recreate real situations in the laboratory.
Finally, in order to understand how power flows are distributed in an electric vehicle, this application incorporates an intelligent regenerative DC power supply. Its purpose is to simulate the behavior of a high-voltage EV battery. The great advantage of this DC power supply is that it can simulate the operation of a lithium battery without the disadvantages that these have: heating risks, risk of toxic gas emissions, explosion risks and limited lifetime.
Optionally, the “AEL-EHV” application recommends the purchase of the electric vehicle charging module. This device is completely real, identical to those used in electric vehicle charging stations.
