Task 1:

In the coursework resources there is excel spreadsheet with technical specifications of various modern electric vehicles. This data has been obtained from https://ev-database.org/website (can be used for further referencing). Student must use last 2 digits of their student number and match the number to the database available in the excel spreadsheet to identify the unique vehicle make, model and its parameters that the student will be working with. Once the vehicle technical details have been identified, the following tasks should be performed:

1. Adjust model parameters (such as motor rated power, battery capacity, vehicle mass, etc.) for the model to represent the student's unique vehicle. Summarise in a table all the vehicle's technical specifications that have been used to adjust the model.

ANSWER WITH EXPLANATION

1.1 Adjust model parameters:

To summarize the parameters in a table, you could do something like this:

1.2. Adjust the model to employ WLTP drive cycle:

The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) is a testing process that measures fuel consumption, CO2 emissions, and pollutant emissions from passenger cars. It also includes a test for electric vehicles, measuring the power consumption and range. Adjust your model so that it emulates the conditions of the WLTP drive cycle and run the simulation. Compare the simulated range value with the WLTP range value provided in the spreadsheet.

1.3. Analyse the model: This part of the task requires you to critically analyze your model. Consider the following points:

• What are the assumptions your model makes? For example, does it assume a flat terrain? Does it assume constant temperature? Does it assume that the vehicle operates at peak efficiency at all times? Each of these assumptions simplifies the real-world conditions under which the vehicle operates.

• What factors are ignored in your model? Perhaps your model doesn't consider wind resistance, or the gradual decrease in battery efficiency over time.
