Description

Electric motor car trades electric system Technical Field The utility model relates to the technical field of electric vehicle power conversion, in particular to an electric vehicle power conversion system. Background At present, the electric vehicle travels in a very common phenomenon, but is limited by the problem of cruising, and the electric vehicle cannot meet the travel requirements of a longer time or a long distance. In order to further improve the cruising ability of the shared electric vehicle, a self-service power conversion system begins to appear. However, due to the difference of the careful degrees of the users, under the condition that whether the battery is returned to place or not is not confirmed by some users, the full-power battery is taken away in a hurry, so that the battery which is not returned to place is easy to steal, or is always in a low-power state because of not entering a charging state, so that the battery cannot be replaced and taken again, and the sustainable operation of the self-service power conversion system is influenced. Disclosure of Invention The utility model aims to overcome the defects in the prior art, and provides the electric vehicle power conversion system which is used for supervising a user to completely return the replaced battery to the right position and solving the problem that the battery which is not returned to the right position is easy to be stolen. In order to achieve the above purpose, the electric vehicle power conversion system comprises a cloud platform, power conversion equipment, a battery management module and a user terminal, wherein the cloud platform is in communication connection with the power conversion equipment, the battery management module and the user terminal; The battery management module is arranged in the shell of the battery, and comprises a state detection unit which is used for detecting whether the battery is in a charging state or not; The power conversion equipment comprises a battery storage module and a central control module, wherein the central control module is in communication connection with the cloud platform, the battery storage module is provided with a power conversion execution unit, a control signal output end of the central control module is electrically connected with a control signal receiving end of the power conversion execution unit, and the power conversion execution unit is used for selectively opening an empty cabinet cavity cabinet door or a full cabinet cavity cabinet door according to a control instruction. Further, the battery storage module is further provided with an in-place insertion sensing module, and an in-place insertion sensing signal output end of the in-place insertion sensing module is electrically connected to the central control module. Further, the battery storage module comprises a plurality of battery storage cabinet cavities, each battery storage cabinet cavity is correspondingly used for storing one battery, and each battery storage cabinet cavity is internally and correspondingly provided with one inserted sensing module.
