Power battery health assessment method based on electric vehicle charging pile management platform

Abstract

The invention discloses a power battery health assessment method and device based on an electric vehicle charging pile management platform, equipment and a medium. The method comprises the steps of: using a charging pile for obtaining a target temperature when the charging charge quantity of a power battery of a target electric vehicle reaches a preset charging state in each charging process; whenthe power battery reaches a preset charging stopping condition in each charging process, obtaining a target charging charge quantity; judging whether the target temperature is within a preset range or not; if yes, fitting a charging model of the power battery, and determining a predicted charging charge quantity of the power battery at the target number of times according to the charging model; screening the charging charge quantity meeting a preset screening condition from the target charging charge quantity to obtain a screening charge quantity group, and obtaining a charge average value ofthe screening charge quantity group; and evaluating the health condition of the power battery according to the predicted charge quantity and the charge average value. Obviously, the management experience of an operator in the management process of the electric vehicle can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a power battery health assessment method, device, equipment and medium based on an electric vehicle charging pile management platform. Background technique [0002] At present, the health status of electric vehicle power batteries can usually only be measured and evaluated by the power battery manufacturers. Under this technical background, it not only makes it impossible for operators to obtain the health status of the electric vehicle power battery in a timely and accurate manner, but also makes it impossible for operators to provide users with value-added services related to the health status of the power battery, which greatly reduces the operation efficiency. The management experience of the dealer in the management process of electric vehicles. At present, there is no more effective solution to this technical problem. [0003] It can be seen that how to improve ...
