Introduction

Coventry University (CU) is inviting applications from suitably-qualified graduates for a fully-funded PhD studentship. This project focuses on accelerated ageing test and life time prediction of battery energy storage system.

Project Details

Battery energy storage is a critical component in electric vehicles including electrified cars, ferries and aircrafts. The battery’s performance degrades with time and usage, and understanding the ageing process and the stress factors is key for cell selection, module/pack design and optimal control of the battery system. The ageing process of battery can take several years under normal operating condition before reaching end of life. Therefore, accelerated ageing test is necessary to reduce the test time.

This project aims to develop optimal design of experiment (DoE) method for accelerated battery ageing test to minimise the cost of test while improving the lifetime prediction accuracy. Smart-cells with in-situ electrochemical and thermal sensors will be used to capture and quantify the battery’s internal ageing process to identify the dominant ageing mechanisms and the major stress factors, such as a specific combination of SoC, temperature and current rate that leads to lithium plating. A battery ageing model will be developed after processing the test data to enable optimal control of the battery system to prolong service life.

Funding

This is a fully-funded studentship, including tuition fees, stipend/bursary and additional allowances. 

Benefits

The successful candidate will receive comprehensive research training including technical, personal and professional skills.

All researchers at Coventry University (from PhD to Professor) are part of the Doctoral College and Centre for Research Capability and Development, which provides support with high-quality training and career development activities. 

Entry Requirements

  • A minimum of a 2:1 first degree in a relevant discipline/subject area with a minimum 60% mark in the project element or equivalent with a minimum 60% overall module average.

PLUS

  • The potential to engage in innovative research and to complete the PhD within a 3.5 years
  • Adequate proficiency in English must be demonstrated by applicants whose first language is not English.  The general requirement is a minimum overall IELTS Academic score of 7.0 with a minimum of 6.5 in each of the four sections, or the TOEFL iBT test with a minimum overall score of 95 with a minimum of 21 in each of the four sections.

For further details please see our information on research entry criteria.  

Additional Requirements
  • Experience in at least one programming language, such as m language in MATLAB, C and C++
  • Experience in system modelling, simulation or control design
  • Willing to work closely in a team and the ability to deliver research outcomes to meet deadlines

How to apply

All applications require full supporting documentation, a covering letter, plus a 2000-word supporting statement showing how the applicant’s expertise and interests are relevant to the project.
