Clock Synchronization Method for Energy Storage System, Power Conversion System, and Energy Storage System

Abstract

A clock synchronization method for an energy storage system includes: acquiring a cable length between a primary controller and a first secondary controller nearest to the primary controller to obtain a first cable distance, and determining a first delay time at least based on the first cable distance; where the first delay time corresponds to a phase difference between a clock of the first secondary controller and a clock of the primary controller; and transmitting the first delay time to the first secondary controller within a predetermined time period to enable the first secondary controller to adjust its clock based on the first delay time to achieve clock synchronization between the primary controller and the first secondary controller. The method at least addresses the problem of high costs caused by clock synchronization via electrical connection between a primary controller and a secondary controller. 20 25 25 98 06 28 O ct 2 02 5 A B S T R A C T 2 0 2 5 2 5 9 8 0 6 2 8 O c t 2 0 2 5
