The invention discloses a method for searching a path of an electric energy metering device based on a password chip. The method comprises the following steps: receiving target identification information, encrypted by the password chip, of a target electric energy metering device; Decrypting the encrypted target identification information, and determining target position information correspondingto the target identification information by calling a pre-stored corresponding relation between the identification information and the position information; planning navigation path according to the current position information of the maintenance personnel and the target position information, whrein the path planning mode is more efficient and convenient; Moreover, the target identification information is encrypted through the password chip, so that the safety of the target identification information in the transmission process is higher, and the safety of the planned information of the finding path of the electric energy metering device is further ensured. The invention also discloses a password chip-based electric energy metering device path searching planning device, equipment and a computer readable storage medium, which all have the above beneficial effects.
