AGV requires charging after every shift that lasts between eight to 12 hours. Speaking of the charging method, it can be divided into two modes: online charging and offline charging:

Online charging – It means using the spare time of the AGV to temporarily stay to charge, without deviating from its working route or charging at a specific time.

Offline charging – This mode means that the AGV needs to be driven into a fixed charging station in order to charge, and a specific charging time is required.
