Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0028] Lithium-ion battery pack remote monitoring and fault diagnosis system mainly includes two core components: data acquisition unit and remote service center.

[0029] The data acquisition unit mainly collects information on the VCU (vehicle controller) 1 of the electric vehicle, including a fault code unit 2 , a GPS positioning signal unit 3 , and a vehicle status signal unit 4 .

[0030] Each lithium-ion battery pack of an electric vehicle has a corresponding code, which is composed of the module number composed of the vehicle VIN code, battery box number, battery pack barcode, and sorted cells. It can be determined by different designers, as long as the corresponding code can be formed. The fault code unit 2 is to collect the code corresponding to the lithium-ion battery pack, and grasp the corresponding faulty lithium-ion batte...
