The invention provides an electric accounting machine (EAM) system for an electromobile power control system assembly. The EAM system comprises a program control unit (PCU) on-site terminal and a background server, the PCU on-site terminal comprises a data acquisition unit for collecting data from a power control system, a first analytical unit used for conducting vehicle state detection according to collected data and a data forwarding unit for sending the collected data to the background server. The background server comprises a second storage unit for storing relevant data loaded on the power control system at different times and a second analytical unit for detecting vehicle states according to all historical data of the power control system. The invention further provides a corresponding method. Fault detection in two types is respectively carried out by the PCU on-site terminal and the background server according to real-time data and the historical data, and traditional passivity overhaul is converted into positive preventative maintenance.
Description
technical field [0001] The invention relates to the field of electric vehicle maintenance, and more specifically, relates to an electric vehicle power control system assembly EAM system and method. Background technique [0002] With the continuous development of the new energy field, the electric vehicle industry has made great progress. The power control system (PCU) is the core component system of the electric vehicle, which is responsible for multiple functions such as control, calculation, signal conversion processing, fault diagnosis, communication and driving. Carry out reasonable power distribution and coordinate the energy flow among various components to improve the power, safety and efficiency of the vehicle. [0003] The safety and reliability of electric vehicles are the focus of social attention and also the core indicators of electric vehicles. At present, the repair and maintenance of electric vehicles is basically the same as that of traditional vehicles, t...
