About the Project
Battery technology, lifetime, charging time, safety, and cost are the major concerns for widespread use of EVs than the conventional fossil fuel vehicles. The performance and lifetime of battery modules not only depends on design, manufacturing process and type of the batteries but also depends on their charging and discharging profile. Therefore, battery chargers play a vital role in the commercialization of EVs.
The battery chargers are classified as on-board and off-board (standalone) chargers. The on-board charger is placed inside the vehicle which provides flexibility to charge from the ac mains and does not need any expensive infrastructure. However, these chargers are limited to low power level, capable of slow charging, and have negative impact on the vehicle’s weight.
One solution is to design high power on-board chargers without increasing the weight and cost of the system by re-utilizing the existing electric traction motor and power electronics components for the charging.
Modular multilevel converter (MMC) is a potential candidate to be used in integrated drive and battery charger system. It is very popular converter in high voltage and medium voltage applications and can be also used as a battery management system by replacing the SM capacitor with battery cells.
This PhD project includes:
- Literature survey on different types of battery chargers for EVs especially the integrated charger and battery management systems
- Determine the performance indices (such as cost, size, lifetime, reliability and complexity) for the integrated charger and battery management systems
- Design of the integrated charger and battery management systems based on MMC technology (Electrical and Control)
- Modelling and simulation of the designed system
Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Electrical Engineering or Control Engineering.
Knowledge of electrical vehicles, battery and AC/DC converters.
Ability to do mathematical analysis and modelling in simulation tools like MATLAB/Simulink, PSCAD, etc.
