Abstract

The invention relates to the technical field of trolley cars, in particular to a pure lithium battery driven traction system for trolley cars, includes ground-based high-power chargers, Pantograph, high power pure lithium battery, traction converter, traction motor, main contactor, As the only power source of tram, high-power pure lithium battery, avoid the disadvantage that the catenary line affects the city appearance, while avoiding costly infrastructure costs, high-power ground chargers need only be installed at the first and last stations on the ground platform of the tram, The electric energy stored by the high-power pure lithium battery can also meet the rescue task when the trolley is running on the main line, and the rescue vehicle does not need to be specially equipped with the rescue vehicle, which is economical and efficient. The invention can realize the rapid charging of the trolley and can meet the electric energy demand of the whole line of the trolley.
