This is Mohanad Ayman, I work as an Instrumentation and control engineer with experience in Mega power plants EPC Projects
My relevant projects are :
1) Electrical car team member at Cairo university : Regenerative braking , Motor driver(Inverter) and monitoring system.
2) complex control systems designs starting from the process flow diagrams, P&IDs till instrumentation selection, and control loops design and simulation via Simulink.
3) Power electronics design (Inverter , DC-DC Converters , PV systems).
I have completed a similar project before , I suggest inserting a buck-boost DC-DC converter to the common DC , this will be beneficial because that will assist us implementing the regenerative braking concept where some of the energy are reverted back to the batteries while braking .
Kindly check my portfolio for similar projects , I kindly request from your side the batteries datasheet and the system voltage . thanks
