Description

Technical field [0001] The invention relates to a system in the technical field of electric vehicles, in particular to an electric vehicle mobility management system. Background technique [0002] The mobility of an electric vehicle refers to the driving distance, driving range, and destination of an electric vehicle, which is mainly based on the battery performance and its management system. The performance of the battery management system directly determines the accuracy of battery / battery pack life prediction estimates and the efficiency of electric vehicle mobility. Research on effective diagnosis and prediction systems for battery health will greatly improve the utilization of battery systems. The battery management system detects the working parameters of the power battery (such as voltage, current, temperature, remaining power and health status) to ensure the safe operation of the power battery / battery pack, and accurately estimates the working state of the power battery / b...

Problems solved by technology

Disadvantages of traditional maintenance techniques are: batteries need to be removed and expertise is required to achieve this detection

The traditional battery management system only charges or replaces the battery after the battery is exhausted. The disadvantages include the long charging time, and the user needs to be patient. Its estimation of the remaining power of the electric vehicle battery is also based on this kind of full- The model obtained from the fixed-cycle experiment at the end of discharge lacks dynamic prediction, does not consider the impact of different electric vehicle user behavior patterns on battery energy consumption, and does not consider the impact of different road conditions and routes on electric vehicle battery energy consumption. There is no functional interaction technology and method to provide service suggestions to users based on dynamic analysis of electric power and electric vehicle user behavior habits

Furthermore, the models used in the battery management systems described in the prior art lack online update capability
