Performance & Efficiency Improvement of Electric Vehicle Power Train 2019-28-2483
Introduction: The advent of electric mobility is changing the
conventional mobility techniques and their application in
automobiles across all segments. This development comes with
challenges ranging across varied sub -systems in a vehicle
including Power Train, HVAC, Accessories, etc. Objective: This
paper would concentrate on the Power train related sub systems
& improvement of the same both in terms of Efficiency &
Performance. Methodology: The electric power train consists of
three major sub parts: 1. Motor Unit 2. Controller with Power
electronics 3. Battery Pack with BMS We would concentrate on
improving the overall efficiency and performance of all these
subsystems while they perform in vehicle environment and work in
tandem by deploying following techniques: a. Improved Regenerative
Braking for converting vehicles Kinetic energy into electrical
energy using specific algorithms and control techniques b.
Optimization of Design Specs and duty cycle based on real world
driving cycles. c. Innovative Heat dissipation techniques to
minimize energy loss to heat. d. Efficient Electrical to Chemical
Energy conversion and vice versa through use of optimization
techniques based on battery characterization Data. Results: Based
on our Initial Proof of concept level experimentation we expect a
improvement in efficiency of the tune 15-20 % through these
optimization techniques. Innovation/New Idea: These techniques have
not been adopted using a system level approach as per our
knowledge. The innovation is in the integration of various
techniques to create a better Power Train as a whole. Conclusion:
These techniques when optimized and applied together can
significantly improve the efficiency of electric vehicles and make
them a more viable option.
