| The key components of an electrified platform include HV battery pack, an e-drive system, HVAC, and other electromechanical components. Design of an electric drivetrain is often a collaborative effort between diverse groups and model sharing and reuse becomes important. In this project, a battery electric vehicle is modelled with components available in different fidelity, for you to select and run based on application need. The vehicle model is a coupled electrical, mechanical, and thermal model built using Simscape™, Battery™, Simscape Driveline™, Simscape Electrical™, and Simscape Fluids™ Libraries. |  |
In this project, you will learn about the following seven engineering workflows:
 |
Estimate the on-road range of the vehicle. Run drive cycles with different ambient conditions to determine the range of the vehicle with a given capacity. See Workflow/RangeEstimation. |
 |
Size your high-voltage (HV) battery pack to achieve your desired range. You will learn how to simulate battery packs with different capacities and weights, and compare them based on how these factors affect the range of the vehicle. See Workflow/BatterySizing. |
 |
 |
Find parameters for an equivalent circuit based battery model from HPPC test data. See Workflow/CellCharacterization. |
 |
Build a neural network model to predict battery temperature. This Neural network model takes in battery voltage and current measurements to predict battery temperature. This, when deployed, can help in eliminating some thermal sensors in the battery pack and reduce cost of development. See Workflow/BatteryNeuralNetModel. |
 |
Drive units with fixed gear ratio are usually the most cost effective option for battery electric vehicle. To determine an appropriate fixed gear ratio, run a design of experiment (DoE) which covers a range of gear ratios and test cycle parameters. See Workflow/GearRatioSelect. |
| Learn how to generate a permanent magnet synchronous motor (PMSM) for a system level (electro-thermal) simulation by creating a motor loss map and integrating it into the system level blocks. See Workflow/GenerateMotInvLoss. |  |
 |
Estimate the inverter power module semiconductor device junction temperature variation due to switching and predict the lifetime of the inverter. See Workflow/InverterLife and Workflow/ThermalDurability. |
