A Practical Circuit-based Model for State of Health Estimation of Li-ion Battery Cells in Electric Vehicles

In this thesis the development of the state of health of Li-ion battery cells under possible real-life operating conditions in electric cars has been characterised. Furthermore, a practical circuit-based model for Li-ion cells has been developed that is capable of modelling the cell voltage behaviour under various operating conditions. The Li...

Improving Ultra Fast Charging of LiFePO4 batteries at low temperatures with AC heating

The speed at which electric vehicle batteries can be charged usually depends on the available charging power. At low temperatures however, another bottleneck appears when the battery is unable to accept all available charging power. The charging speed is then limited by the battery. To fix this, the battery could be equipped with a heater so...
