AI Technical Summary

Technical Problem

Existing OTA upgrade solutions for charging piles are prone to impacting the power grid and user services during large-scale upgrades, and lack in-depth verification of critical equipment status, resulting in security risks and high operational complexity.

Method used

By acquiring real-time status parameters of the charging pile cluster and power grid load forecast data, an upgrade execution queue is dynamically generated. The upgrade differential package is used and the new version is pre-run in the backup system partition. Combined with deep security verification and dual-partition hot backup technology, a seamless upgrade is achieved.

Benefits of technology

This reduced the burden of the upgrade on the power grid, ensured equipment safety and service continuity, and improved upgrade efficiency and user experience.

Abstract

This application relates to the field of new energy vehicle charging infrastructure technology, and provides an OTA upgrade method, device, and storage medium for intelligent charging equipment. The method includes: acquiring upgrade task instructions for a charging pile cluster within a target area and real-time status parameters of each charging pile; dynamically generating and optimizing an upgrade execution queue; issuing corresponding upgrade differential packages to the charging equipment to be upgraded, which are then received and stored in a backup system partition; performing pre-upgrade compatibility and security checks before activating the upgrade differential packages; upon successful verification, loading and pre-running the new version of the upgrade differential package in the backup system partition, maintaining the current charging service in the main system partition; switching system control from the main system partition to the backup system partition when the pre-run test passes and preset switching conditions are met; and clearing the old version program resources in the main system partition after confirming stable operation of the new version program, thus completing the upgrade.
