electric public transport system, method for operating an electric public transport system and method for charging a battery pack in a case used in an electric public transport system

摘要

Electric public transport system The present invention relates to an electric public transport system comprising electric powered buses with a battery pack in a case, and an onboard control system of the bus, an electric charging station and a loading and unloading apparatus. when said bus needs to replace the battery pack in a case, said charging and discharging apparatus removes said case battery pack from said bus and then replaces it with a charged case battery pack. said electric charging station and also said battery pack charging and discharging apparatus are equipped with their respective control systems which can intercommunicate with said bus mounted control system. In the present invention, the battery packs in a case are electrically charged during utility interruptions, and therefore, the transportation system can save energy and benefit the environment. In addition, it is also fast and accurate to charge and discharge the battery pack in the system of the present invention, which can also ensure that the bus operates continuously on the line and greatly increases the bus utilization rate.
