Hannan M.A. Mohamed A. 56583590200 7103014445 57195440511 Charging (batteries); Controllers; Electric batteries; Electric machine control; Electric vehicles; Equalizers; Optimization; Particle swarm optimization (PSO); Secondary batteries; Voltage control; Control techniques; Discontinuous current mode; Flyback converters; Optimal algorithm; Particle swarm optimisation; PI controller parameters; Switching signals; Vehicle applications; Lithium-ion batteries A charge equalisation controller (CEC) was developed for continuously monitoring individual battery cells and equalising the charge or voltage levels of all cells in a series pack. A charge equalisation control algorithm was developed to equalise undercharged, overcharged, and unprotected cells through the use of a bidirectional fly-back converter. The equalisation involves charging and discharging by employing constant current�constant voltage and discontinuous current mode proportional�integral (PI) control techniques. Particle swarm optimisation is applied to optimising the PI controller parameters that generate the regulated pulse width modulation switching signal for the converter. A CEC model was applied to 90 lithium-ion battery cells (nominally 15.5 Ah and 3.7 V each) connected in series. The results showed that the developed CEC model performed well at equalising both undercharged and overcharged cells with ?92% efficiency and equalised every cell within the safe operation range of 3.73�3.87 V. The developed system realises excellent equalisation speed, a simple design and efficiency with low power loss. Thus, the CEC model has great potential for implementation in real-world electric vehicle energy storage systems. � The Institution of Engineering and Technology 2017.
