Title:
AGV CHARGING METHOD AND SYSTEM FOR AUTOMATED TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/093660
Kind Code:
A1
Abstract:
Disclosed in the present invention are an AGV charging method and system for an automated terminal. Said method comprises: determining, during operation of an AGV, the battery level range to which the current battery level belongs; when the battery level is within a first battery level range, controlling the AGV to operate normally, and circularly charging same during operation in a sea-side interaction zone of a container yard; when the battery level is within a second battery level range, controlling the AGV to operate normally, and to travel to a set position for charging after the current operation is completed; and when the battery level is within a third battery level range, controlling the AGV to travel to the set position for charging; the first battery level range being higher than the second battery level range, and the second battery level range being higher than the third battery level range. The present invention divides the AGV battery level into battery level ranges, and implements different charging policies for different battery level conditions, aiming to maintain, at the maximum probability, the AGV at low depth of charge/discharge, achieving the effect of extending the service life of the battery.
