Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematics methods as well as the ability to describe particular systems and processes in the final examination. The coursework element allows students to demonstrate that they can interpret a problem, develop design targets, and present and justify a solution clearly and accurately. Thus, the summative assessment for this module consists of: Coursework on Battery modelling & simulation [Learning outcomes 2, 3 ] Coursework on battery pack design [Learning outcomes 2, 4] Examination [ Learning outcomes 1, 2, 3, 4 ] Formative assessment and feedback Formative verbal feedback is given in tutorials & lectures. Written feedback is given on the coursework assessment

Methods of Teaching / Learning

The module will be delivered by lectures and tutorials. The tutorials will allow stundets to apply the theory from the lectures to engineering problems.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Other information

The School of Mechanical Engineering Sciences is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills and capabilities in the following areas; Employability: This module provides students with knowledge about the principles, mechanisms, materials, operation and management systems for energy storage devices and systems used in electric vehicles, aircraft, robots and the grid. As such, it facilitates students employability in any type of electrified transport or robot or moving platform industry (automobile, robots, aircraft, spacecraft, e-boat, e-bicycle) and the grid with renewables; also in the field of energy storage packs and devices (batteries, supercapacitors, fuel cells), as well as related materials. Digital capabilities: Students will implement battery models in digital platforms and run simulations to evaluate and gain understanding of the battery systems for specific applications. This is conducted as part of the guided learning activities, tutorials and coursework 1 which then feed into the class discussions. Global and Cultural Capabilities: Charts illustrating the progress of transport electrification, electric energy supply sources and the grid for different countries and groups of countries are presented in the lectures. Also, regulations for environmental emissions in different countries and regions are presented in the lectures. Sustainability: The position and key role of the energy storage system for clean energy supply and reduction of environmental emissions is clearly presented in this module. Method to calculate CO2 eq. emissions in cars and other transport is presented. The issues of critical raw materials, such as lithium, and sustainability of batteries are discussed. Sustainable battery technologies with abundant materials are also introduced. Resourcefulness and resilience: Students will develop resourcefulness in responding to problem-based task requirements and battery pack design problems through sharing ideas and experiences both individually and collectively, appreciating potential barriers and challenges faced by others, providing support and showing empathy towards each other in working towards achieving successful outcomes.
