Abstract: Lithium-ion battery forms an integral component in a hybrid electric vehicle. In a very cold climatic condition, it undergoes severe energy loss, poor performance and reduced life-cycle and therefore requires self-heating before starting. In this paper, a self-heating device that involves a resonant switched capacitor (RSC) heater with fast heating speed and high conversion efficiency was evaluated. The mathematical modeling and control of the RSC converter is presented. Simulation was carried out on the modelled equations and results obtained showed that the battery charging current significantly improved when the characteristic impedance of the model was increased. The RSC-heater conversion efficiency also increased to 91.05% at an increased characteristic impedance value of 4.5Ω All simulation processes were achieved in MATLAB/SIMULINK 2015 version.
