Embodiment Construction

[0027] With reference to the drawings, the preferred embodiments of the present invention will be further described in detail.

[0028] The remote monitoring and fault diagnosis system for lithium-ion battery packs mainly includes two core components: a data acquisition unit and a remote service center.

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

[0030] Each lithium-ion battery pack of an electric vehicle is compiled with a corresponding code. The code is composed of a module number composed of the vehicle's VIN code, battery box number, battery pack barcode, and sorting cell. 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 lithi...

Abstract

The invention discloses a remote monitoring and fault diagnosis system for lithium ion battery packs, which comprises a data acquisition unit and a remote service center, wherein the data acquisition unit comprises a fault code unit, a GPS (global position system) location signal unit and a vehicle state signal unit; the remote service center comprises a remote service workstation, a remote diagnosis server, a database and a man-machine interactive real-time monitoring system; the fault code unit is used for acquiring a corresponding code of each lithium ion battery pack of an electric vehicle, the GPS location signal unit is used for acquiring position signals of the vehicle, and the vehicle state signal unit is used for acquiring working state signals of the vehicle; and the remote service workstation carries out remote transmission on signals acquired by the data acquisition unit, the remote diagnosis server receives signal data of the remote service workstation, then the signal data are processed and analyzed by a data processing module in combination with the database, and then, results subjected to processing are displayed on the man-machine interactive real-time monitoring system. By using the system disclosed by the invention, the remote communication, fault monitoring and fault diagnosis for lithium ion battery packs are realized.

Description

technical field [0001] The invention relates to the technical field of automotive power battery systems, in particular to a remote monitoring and fault diagnosis system for lithium-ion battery packs. Background technique [0002] With energy shortages, rising oil prices, and increasingly serious urban environmental pollution, it is imperative to adjust the structure of the automobile industry and develop new energy vehicles. With the breakthrough of the core technology of pure electric vehicles, lithium-ion batteries have become a hot spot in the development of electric vehicles in the world due to their high energy density and power density, long cycle life, light weight and environmental protection. The development of pure electric vehicles has become the realization of the automotive industry Transformation is the key to achieving a win-win situation of economic development and environmental protection, and the sustainable development of the automobile industry. It is also...
