Abstract Energy management strategy is the crucial part of the design of tram’s hybrid power system and the result has directly influenced the operation performance and economic benefit of tram. This paper put forward the dynamic ratio distribution strategy for hybrid storage system of tram. Firstly, the power distribution paths of optimal efficiency with different voltage range was worked out, secondly, the discrete time was optimized based on the maintained effects of dynamic programming, and the complicated power distribution strategy was transformed into the simple rules that power ratios change over discrete time, and the strategy was validated to make the hybrid storage system be with high efficiency and thus decreased life loss caused by heating. Lastly, the strategy was proved to be flexible and effective through simulation and experimental verification.
