Microcontroller Based Li-Ion Cell Balancing using Single Switched Capacitor for Spacecraft Application

IJEECC Front Page

Abstract:
The emerging plugin hybrid vehicle technology requires larger battery packs which do not compromise on its lifetime and performance and battery weight. Due to the manufacturing defects and performance variations of each individual cell in the pack, charge balancing is necessary In this paper we simulated and plotted using MATLAB/Simulink software. This paper aimed at proposing a microcontroller based Li ion cell balancing using single switched capacitor (SSC). SSC technique provides an efficient control over other techniques. This method help to reduce the thermal power consumption and power loss as compared with the passive topologies. It also provides higher efficiency and accuracy. This paper also includes a review and comparisons between the double tiered and single switched capacitor balancing topologies for battery string based on MATLAB/Simulink simulation. The comparison carried out according to circuit design, balancing simulation, practical implementations, application, balancing speed, complexity, cost, size, balancing system efficiency, voltage/current stress etc.
Keywords:Li-ion cells, Cell balancing, microcontroller, Single Switched Capacitor(SSC), MATLAB simulation, charge transfer algorithm.
