Next Meeting: Prof David Howey, Batteries and Beyond

25th April, 2018

David Howey is an Associate Professor in Engineering Science and a Tutorial Fellow at St Hilda’s College Oxford. His team's primary interest is in the modelling and management of electrochemical energy storage devices for automotive applications such as electric and hybrid vehicles, and also grid and off-grid power systems. The group develops novel instrumentation, diagnostics and modelling approaches that enable operation closer to performance limits, which is essential in order for these systems to reach commercial viability and make a positive impact on society and the environment.

Prof Howey's lab includes a range of battery test equipment, thermal imaging and calorimetry, data acquisation, scopes, 4Q power supply/loads, a dSpace battery simulator, and a 3D printer. Some examples of work include:

  • Improved modelling of battery open circuit voltage (OCV) for battery management systems.
  • A system for measuring electrochemical impedance using existing power electronics to excite a battery - this can be used for temperature estimation in cells amongst other things.
  • Development of advanced battery management systems (BMS) that use electrochemical models for state estimation (also relevant for supercapacitors)
  • Modular BMS/power electronics/battery systems that enable matching different types of cells together to get the most out of each of them.
  • A novel electrical system for measurement of convective heat transfer in motors.

Prof Howey studied engineering specialising in electrical and information sciences at Queens’ College, Cambridge University. After working as an engineering consultant, he undertook a PhD at Imperial College London on the subject of thermal design of electrical machines. Subsequently he worked as a post-doctoral researcher at Imperial on two automotive projects investigating electrically assisted turbocharging and advanced battery condition monitoring before being appointed at Oxford in 2011 where he heads up the Howey Research Group.

Prof Howey states:

The main focus of our research is energy storage systems for automotive, grid, and off-grid applications. We also have a small secondary focus on electrical machines. You can find out more about our specific themes by clicking through the pictures below. Lithium-ion batteries are a key area, but we also investigate lead-acid and sodium-ion batteries, supercapacitors, flow batteries, and fuel cells. We collaborate widely with industry; many of our partners are at the bottom of this website.

There are many interesting challenges for the large-scale uptake of electrochemical energy storage including system integration, degradation, thermal management and dynamic modelling. Operating devices outside safe limits of temperature, voltage and current may lead to catastrophic failure. Moreover, integration into higher-level vehicle and grid environments is challenging because properties of interest such as state of charge and state of health are not directly measurable. Performance also deteriorates as a result of various degradation mechanisms and the complexity and interactions of these mechanisms make it difficult to predict decreases in battery capacity and power capabilities accurately.
