Networked automobile battery management system

The invention provides a networked automobile battery management system. A networked automobile comprises an automobile battery for providing a power source for the networked automobile, and the networked automobile battery management system comprises a cloud server and a vehicle-mounted controller located at a vehicle-mounted end. Based on the networked automobile battery management system, the invention further provides an SOC and SOH combined estimation algorithm. The SOC and SOH combined estimation is carried out in a cloud server, so that the algorithm precision loss caused by fixed-pointnumber operation and index lookup approximation of the vehicle-mounted controller is avoided, and the SOC and SOH combined estimation algorithm based on cloud computing can improve the SOC estimationprecision by 2.5-4.5%. The SOH estimation algorithm provided by the invention not only can reflect the DC internal resistance of the battery, but also can calculate the aging state of the internal resistance of the battery un
