This trainer provides students and instructors with the opportunity to demonstrate, investigate, and fault- find a simulation of an Electric vehicle system. The trainer is designed to allow access to a simulation of the mechanical operation as well as provide a mimic of the electrical power flow. The panel also includes test points at a safe voltage level to allow for the investigation of electrical circuits. To facilitate the development of techniques in diagnostics and fault-finding skills, the panel includes a range of fault- insertion options to simulate typical real-world system malfunctions.
The Trainer Kit is completely DIY based where you can easily dismantle and reassemble the whole Electric Vehicle by your Own. Which leads to a complete knowledge from zero to pro level.
As It is a DIY Platform which means you can select different parts of your choice and mount them to study them in details, like Tyre, Battery, Sensors etc..
