Lengthy charging times are a key drawback for Li-ion batteries in consumer applications such as portable electronics and electric vehicles. Current Li-ion battery chemistries have shown potential for much faster charging (up to around 7x faster than manufacturer’s specifications) whilst still remaining within a safe electrochemical and thermal operating envelope.
However, to operate at these higher charging rates requires diagnostic capabilities beyond those typically offered by battery management systems (BMS), which rely on measurements of DC voltage, current and temperature often made on only a fraction of the cells in the system.
New diagnostic techniques capable of detecting fault conditions in real-time are required in order to advance the state-of-the-art in battery management and enable faster charging.
Electrochemical Harmonic Analysis (EHA) ), also known as Non-Linear Frequency Response Analysis (N-FRA) is an emerging technique that has recently been demonstrated for state-of-health estimation and ex-situ (post-mortem) detection of lithium plating. This 3 ½ year PhD project aims to develop this technique (and others) through a combined approach employing electrochemical modelling and practical experimentation on state-of-the-art instrumented Li-ion cells, in order to demonstrate its feasibility for real-time diagnostics and control of ultra-fast charging processes.
Coventry University (CU) has a new eMobility Group based at the Centre for Low Carbon Propulsion Systems (C-ALPS), which is part of the Institute for Future Transport and Cities. The Group brings together existing CU expertise with academics in energy storage, power electronics and electric machines. In total the new group comprises of 21 full time academics making it one of the largest UK based academic teams conducting E-mobility research.
The main focus of the Group is de-carbonisation of transport, with electrification of propulsion systems as a key aspect. This is where the C-ALPS expertise lies, together with the energy storage systems design, assembly and evaluation facilities.
Recent investment into C-ALPS facilities includes:
These facilities enable wide range of research activities– from cell assembly, through formation to battery grading and diagnostics, performance and safety evaluation. In parallel, novel sensor design and application supports the battery diagnostics activities.
C-ALPS also hosts the UK headquarters of FEV, who are a key partner and industrial sponsor of this PhD studentship. FEV’s activities in the automotive sector will provide valuable industry exposure to the successful candidate.
