description The embodiment of the invention provides a vehicle-cloud cooperative battery SOH estimation method and device, and relates to the technical field of vehicle batteries. The method comprises the following steps: establishing cloud aging features by using multi-dimensional feature indexes of cloud parameter variables; establishing vehicle end aging characteristics by using the multi-dimensional characteristic indexes of the vehicle end parameter variables; establishing a cloud multi-mode SOH data driving model and a vehicle end delta SOH data driving model by utilizing the aging characteristics; and based on the constructed model, vehicle-cloud collaborative SOH data driving estimation is carried out. According to the method, the aging features are constructed through the multi-dimensional feature indexes, the advantages of rich cloud data, high computing power, high real-time performance of vehicle-end data and the like are brought into full play, then the cloud model and the vehicle-end model are established b
