Course Overview: 

Accurate energy estimation & Optimization is the most needful for EV powertrain development. Every country has its own challenges in terms of road conditions, drivability, load on vehicles, the purpose of utilization, pattern of utilization, environmental conditions such as temperature, and more. These needs demand extensive simulation studies to make the analytical decisions. Few of the cases as defined below, 

1. Traction motor & cells are highly sensitive to temperature. Cooling the pack & motor intern consume energy from the pack itself. This will impact the rage of vehicle inherently and health of cells without accurate simulation studies
2. The motor is highly efficient in specific regions of its RPM and Torque. How can we gain the best out of it? Is by accurately estimating the loads, choosing the right sized motor, by selecting the right gear ratio and having them optimized
3. Load on the vehicle & pattern of driving can impact on the range of the vehicle. Both the parameters are non-linear and subject to the case. How can we evaluate the powertrain design? By having the right inputs and considering the parameters which can make an impact on energy consumption
4. Regenerative energy can be a great advantage. But, it may impact the cell if not evaluated. Or in case regen is too less and have no utilizable ability
5. Apart from drivetrain loads, there are auxiliary loads such as HVAC unit. Avg. sizing of the HVAC unit is about 2 to 4 kW for the passenger car segment. Proper evaluations need to be done to estimate the energy consumption from the HVAC unit on its operation
6. Other auxiliary loads such as motor cooling & battery cooling also need an accurate estimation
7. And much more studies are needful for better powertrain development
