PhD Position – Investigating the influence of V2G-processes on the lifetime of EV batteries

Updated: about 1 month ago
Location: Germany,
Deadline: 10 Oct 2021

Work group:

IEK-9 - Grundlagen der Elektrochemie

Area of research:

PHD Thesis

Job description:

At the Institute of Energy and Climate Research - Fundamentals of Electrochemistry (IEK-9), we perform research on highly relevant topics related to the energy transition. For example, we investigate new battery concepts and how we can turn the greenhouse gas carbon dioxide (CO2) into the fuel of the future. The aim is to develop sustainable and cost-effective electrochemical systems with improved energy and power density, longer life-time, and maximal safety.

Your Job:

In March 2018 the so-called Living Lab Energy Campus (LLEC) project at Forschungszentrum Jülich (FZJ) was initiated in order to investigate future energy systems on the basis of decentralized and renewable energy. Making extensive use of instrumentation and implementation of data acquisition equipment, control systems, and demonstrator units, LLEC allows real-time analyses, design, and optimization of renewable energy systems. Recently, the LLEC project has been extended with Vehicle-to-Grid (V2G) research. As part of this new project, electric vehicles (EVs) and high-performance charging infrastructure with advanced charging and discharging concepts are integrated into the existing LLEC-infrastructure in order to support the operation of an intelligent, decentralized energy system as well as to investigate the influence of V2G-processes on the behavior of vehicle batteries. The goal of this project is to investigate Li-ion battery aging under the influence of V2G processes. More information about our LLEC-project can be found here: In this project your main tasks are:

  • Explore the various (dis)charge profiles for EVs with V2G-capabilities which are integrated in a smart decentralized energy system
  • Identify the different battery aging mechanisms in relation to V2G processes
  • Further develop existing aging models for use with V2G processes
  • Developing and performing laboratory tests for model validation
  • Optimizing and validation of the developed models based on (laboratory) measurements
  • Propose new concepts for minimizing battery aging under V2G-processes
  • Assist in determining optimal and/or fast-charge protocols that lead to minimum aging
  • Writing scientific documents and presenting the results at meetings and conferences

Your Profile:

  • Excellent university degree (Master) in Electrochemistry, Chemistry, Physics, Electrical or Atomotive Engineering or related field
  • Experience in battery aging and in laboratory experiments with batteries
  • Affinity towards modelling and simulations, preferably in connection with electrochemical energy storage systems
  • Familiarity and experience with programming languages, such as MATLAB
  • Experience in mathematical optimization
  • Strong communication skills and the ability to work in a team
  • High motivation, an interest in the research questions as well as an independent and result-oriented way of working
  • Good communication skills in spoken and written English are mandatory, communication skills in spoken and written German are advantageous

Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We offer ideal conditions for you to complete your doctoral degree:

  • A highly motivated working group as well as an international and interdisciplinary working environment at one of Europe’s largest research establishments
  • Outstanding scientific and technical infrastructure
  • Opportunity to participate in (international) conferences and project meetings
  • Continuous scientific mentoring by your scientific advisor
  • A large research campus with green spaces, offering the best possible means for networking with colleagues and pursuing sports alongside work
  • Further development of your personal strengths, e.g. through an extensive range of training courses; a structured program of continuing education and networking opportunities specifically for doctoral researchers via JuDocS, the Jülich Center for Doctoral Researchers and Supervisors:

  • Targeted services for international employees, e.g. through our International Advisory Service

The position is initially for a fixed term of 3 years. Pay in line with 75% of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund) and additionally 60 % of a monthly salary as special payment („Christmas bonus“).
