Description

Technical Field

[0001] The present disclosure relates to the field of locomotive technology, and in particular to a network communication method between battery-swap new energy locomotives and battery-swap new energy locomotives. Background Art

[0002] With the gradual acceleration of the replacement of old diesel locomotives with new energy sources, more and more application scenarios have begun to plan the replacement of new energy locomotives. However, due to the limitations of charging methods, new energy locomotives generally require sufficient charging time, which seriously affects the promotion of new energy locomotives. Therefore, new energy locomotives with fast battery replacement methods came into being.

[0003] New energy locomotives are generally equipped with multiple groups of power battery cabinets. The assembly of the power battery and the whole vehicle of existing new energy locomotives is fixed, and the communication address of the power battery is a fixed ID (Internet Protocol). When adopting the battery replacement solution, there is uncertainty in the assembly of the power battery and the whole vehicle. The fixed ID communication method is still used. After the battery replacement is completed, the power battery communication address needs to be reset, or through manual management, only the power battery with the same ID is replaced, which seriously affects the efficiency of battery replacement and limits the development of battery replacement technology.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
