Design of 42V Synergic Electric Power for Hybrid Electrical Vehicle

In order to improve battery performance and extend its service life in 42V power supply of hybrid electrical vehicle, will be combine of ultra capacitors and batteries, so that both could output/absorb the high-rate impact current, but also to meet the high-rate current required for high energy density. The paper compared respective advantages and disadvantages of batteries and ultra capacitors as an energy source applied in hybrid electrical vehicle, selected the collectivity project of synergic electric power based on batteries and ultra capacitors, analyzed the work process of synergic electric power, through analysis and demonstration and experimental data validated the scheme is feasible.
