A promising applied technology on hybrid power system for electric vehicle was proposed in this paper. Considring the actual bus working conditions, a testing system of multi-stage pulse discharge was designed. The separated LiFePO4series, lead-acid battery and the paralleled battery pack, constituted by the lithium battery and lead-acid battery with equal capacity, were tested to compare the voltage and power characteristics, as well as temperature rise. The results indicate that the lithium-ion batteries provide momentary high currant at high rate pulse discharge while keeping the lead-acid stay at a higher state of charge and improving its cycle life. During the intermittent, spontaneous capacity redistribution is achieved in the paralleled system, which helps to relieve the potential polarization and avoid the over-discharge of lithium-ion battery. Systematic analysis of the paralleled system demonstrats that it is benefitial to the circuit control, cost, cycle life and safety.

<p>Due to its low cost and recycle-ability, the lead-acid battery is widely used in mobile and stationary applications. Despite much research on lead-acid batteries, the effect of charging voltage on the degradation mechanism requires further investigation. In particular, the origin of cycle life degradation remains unclear. In the present work, by using electrochemical tests and materials characterization, we studied the effect of charging voltage at voltages slightly higher than the open-circuit potential (OCP) i.e., 103-107% OCP, on the battery life cycle. The highest degradation was observed at 105% OCP charging voltage. Based on the materials characterization results, we found that the degradation of a lead-acid battery is influenced by the amount of hard sulfate and the sulfate particles' size.</p>
