The at least one digital watt hour meter 101, the emergency switch 103, the identification apparatus 104 and the electromagnetic lock 105 are respectively connected to the charge management module 102. The at least one plug 106, connected to a vessel electrical charger 301, is connected to a market electricity system 401 and/or a power generating system 402 to provide power to the vessel electrical charger 301. The vessel electrical charger 301 then is allowed to charge a battery set 302 disposed on an electric vessel 300.

In this embodiment, for example, the charge management module 102 is a touch control industrial computer that is operated through a touch display. Thus, a hardware configuration may be simplified while also satisfying a crucial requirement of high space efficiency for vessels. Further, to increase utilization security, the at least one plug 106 may be an interlocking plug.

The identification apparatus 104 verifies a user identification. For example, the identification apparatus 104 is a digital, electronic, biological and/or mechanical identification apparatus. For example, the identification apparatus 104 is capable of identifying radio frequency identification (RFID) systems, quick response codes (QR-code), fingerprints, keys, numbers, voiceprints and/or facial features. Only with a valid verification license obtained from the identification apparatus 104 through a verification medium possessed by a user, a user is allowed to use the on-shore electrical charge system for vessels 110.

The on-shore electrical charging system for vessels 110 of the present invention may further comprise a cover 111. The cover 111 covers the at least watt meter 101, the emergency switch 103 and the charge management module 102. By locking the cover 111 with the electromagnetic lock 105, not only unauthorized contact of the on-shore electrical charging system for vessels 110 is obviated, but equipment or personnel damages resulted by a third person accidentally engaging the present invention are also prevented.

The on-shore electrical charging apparatus for system 110 of the present invention may be connected to a market electricity system 401 and/or a power generating system 402, to provide a power supply for charging. For example, the market electricity system 401 is a power network system established by a local government or by a private power company; the power system 402 is a power generating device such as a gasoline power generator, a diesel power generator or a fuel battery.

The charge management module 102 is connected to the management platform 200 and transmits charge-related information to the management platform 200, so as to allow the management platform 200 to effectively manage the on-shore electrical charge apparatus for vessels 100 from a remote end. The management platform 200, being capable of managing at least one connected on-shore electrical charging apparatus for vessels 100, comprises a charge information inquiry module 201, a charge information collecting module 202, a charge information processing module 203, and a charge information database 204. The charge information processing module 203 is connected to the charge information inquiry module 201, the charge information collecting module 202, and the charge information database 204.

After the charge management module 102 is activated, charging information may be transmitted between the charge management module 102 and the management platform 200 via the Internet on a periodical or manual basis. The charge information includes a user identification, a charge time, a disconnection time, and/or an amount of outputted power supply.

According to an embodiment, a method performed by the charge management module 102 comprises: activating the charge management module (Step 501), verifying a user identification (Step 502), unlocking the cover (Step 503), setting an output mode (Step 504), determining whether to activate the emergency stop switch (Step 508), connecting the plug (Step 509), outputting power supply to the vessel electrical charger (Step 510), disconnecting power as an emergency (Step 511), logging out the user identification (Step 512), and locking the cover (Step 513).

Referring to FIG. 2, the charge management module is activated in Step 501, and the user identification is verified through a verification medium possessed by the user in Step 502. Step 503 is performed if the verification in Step 502 is successful to unlock the cover, or else the method iterates Step 501 if the verification is failed. After unlocking the lock, Step 504 is performed in which the user selects either starting to charge as Step 505 or disconnecting power supply as Step 506. In the event that no command is received from the user after 30 seconds or after a predetermined period, the charge management module 102 logs out in Step 507. In Step 513, the cover is locked, and the method returns to Step 502 to perform the user identification verification step. After performing either Step 505 of starting to charge or Step 506 of disconnecting power supply, it is determined whether to activate the emergency stop switch in Step 508.
