Abstract：Aiming at resolving the absent difficulties of EV and EV charging station accessing to the grid in DC mode such as interface

selection，control strategy. Based on the review of study that has been dressed，method of EV charging station connecting to DC

distribution network was put forward. Then，bi-directional DC/DC converter were analyzed in detail from some aspects such as device

types and functions. Taking the electrical isolation as a basis，the topologies was classified into two categories. Comparison about the

performance of the topologies such as efficiency and control scheme has been made respectively. Three typical bi-directional DC/DC

converter were compared and analyzed. In the final analysis，the results indicate that the two-way three level converters are most suitable

for application and interface technology accessing to the DC distributed network with its high efficiency，simple structure and high

reliability.
