AI Technical Summary

Technical Problem

Traditional thermal management strategies for new energy vehicle power batteries cannot meet cooling requirements at high charging rates, resulting in extended charging times.

Method used

By setting a target temperature, determining the theoretical charging current, and optimizing the predicted temperature when the charging current exceeds the limit, the optimal charging current and time are iteratively calculated to generate the optimal charging path.

Benefits of technology

While meeting battery cooling requirements, we can rationally plan charging paths, shorten charging time, improve charging speed and safety, and enhance user experience.

Abstract

The application relates to a battery charging path planning method and device, a vehicle, a readable storage medium and a computer program product. The method comprises the following steps: setting a target temperature when charging to a preset state of charge, determining a theoretical charging current corresponding to the preset state of charge according to the target temperature; in the case that the theoretical charging current is greater than a limit charging current, determining a predicted temperature of a state before the preset state of charge according to the limit charging current; optimizing the theoretical charging current according to the predicted temperature until the optimized theoretical charging current is less than or equal to the limit charging current; determining a target charging time when charging to the preset state of charge according to the optimized theoretical charging current; and generating a charging path of the battery according to a target charging current corresponding to the target charging time. The method can shorten the battery charging time.
