Nandulal Gavali

1. Modeling and Simulation in Simulink of different Power Electronics converters for Algorithm development. Simulation in LTSpice for hardware control development for different FEV projects.

2. Product Owner for BMS development for new liquid-cooled Battery development. Defined software architecture for BMS for swappable charging and on-vehicle discharging.

3. Designed a low-cost, unity PF, 1KW battery charger for 2-wheelers, as per AIS-156 standard. Two types of model-based CC-CV control have been implemented.

i. PIC18-based supervisory control.

ii. dsPIC33-based cascaded CV and CC controller architecture

4. 48V/3KW PMSM motor control for 2Wheelers.

i. Developed an optimized method for angle calculation from SIN/COS motor sensor

ii. Modification and simplification in conventional FOC algorithm from low cost dsPIC33 implementation perspective.

iii. Develop the method to test the Id, Iq calculation online.

iv. Patent applied for the modification in FOC algorithm.

The method used for development,

a. Leading hardware design and development. Component selection and purchase. Guidance provided to the Hardware design team as per the project timeline.

b. Leading control software and integration team. Define the real-time scheduler and various tasks and ISRs. Integration of platform Model-generated code in IDE. Guidance to model-based software to update the function based on the requirement. Established software development environment for dsPIC33 controller.

c. Provide guidance and support for the test setup development.

Support provided for different Electrification projects.
