Best Mode for Carrying Out the Invention

[0008] In the following description, the reference numerals of the components cited are treated as the same or similar elements shown in different drawings. These embodiments are only a part of the present invention and do not disclose all possible implementations of the present invention. Rather, these embodiments are merely examples within the scope of the patent application of the present invention.

[0009] Referring to FIG. 1, FIG. 1 is a schematic diagram of a power management system according to a first embodiment of the present invention. In the present embodiment, the power management system 100 includes control devices 110_1 and 110_2, a wireless charging platform 120, and a remote monitoring device 130. The control devices 110_1 and 110_2 are respectively provided in the electric assist carriers EV1 and EV2. In the present embodiment, the control device 110_1 is provided in the electric assist carrier EV1. The control device 110_2 is provided in the electric assist carrier EV2.

[0010] In the present embodiment, the wireless charging platform 120 communicates wirelessly with the control devices 110_1 and 110_2. The wireless charging platform 120 performs wireless charging in any method for at least one of the electric assist carriers EV1 and EV2. In the present embodiment, the wireless charging platform 120 can perform different power supply operations based on commands from the control devices 110_1 and 110_2. Taking the electric assist carrier EV1 as an example, the control device 110_1 can provide one of the first command CMD1 and the second command CMD2. The wireless charging platform 120 performs wireless power supply to the electric assist carrier EV1 in response to the first command CMD1 from the control device 110_1. For example, the wireless charging platform 120 can convert the external electrical energy PE into charging electrical energy PC and use the charging electrical energy PC to perform wireless power supply to the electric assist carrier EV1. The external electrical energy PE may be supplied from a power grid or a commercial power source.

[0011] Furthermore, in response to the second command CMD2, the wireless charging platform 120 wirelessly supplies power to other electric assist carriers (i.e., the electric assist carrier EV2) using the battery energy PB of the electric assist carrier EV1.

[0012] In this embodiment, the remote monitoring device 130 wirelessly communicates with the wireless charging platform 120 to receive the remaining power of the electric assist carriers EV1 and EV2. The remote monitoring device 130 controls the power supply operation of the wireless charging platform 120 based on the remaining power of the electric assist carriers EV1 and EV2 and the platform power supply amount upper limit PLM. For example, the wireless charging platform 120 provides the platform power supply amount PP to the remote monitoring device 130. The remote monitoring device 130 determines the platform power supply amount PP. When the platform power supply amount PP is greater than the platform power supply amount upper limit PLM, the remote monitoring device 130 uses the notification signal SN to notify the wireless charging platform 120 to reduce the load. Accordingly, the platform power supply amount PP decreases.

[0013] Note that the remote monitoring device 130 can control the power supply operation of the wireless charging platform 120. Furthermore, the wireless charging platform 120 can wirelessly supply power to at least one of the other electric assist carriers using the battery energy of the first electric assist carrier EV1. The power consumption of the external electric energy PE can be reduced. In this way, the power management system 100 can provide an energy-saving and efficient wireless power management mechanism.

[0014] In this embodiment, the wireless charging platform 120 performs wireless power supply to at least one of the other electric assist carriers by using the battery energy PB of the electric assist carrier EV1 in response to the second command CMD2. For example, the control device 110_1 can convert the battery energy PB of the electric assist carrier EV1 into wireless electrical energy PB'. The wireless charging platform 120 receives the wireless electrical energy PB' and performs wireless power supply to at least one of the other electric assist carriers by using the wireless electrical energy PB'.

[0015] In addition, the wireless charging platform 120 provides a usage bonus BNS corresponding to the electric assist carrier EV1 based on the wireless electrical energy PB' received by the wireless charging platform 120 itself. For example, the electric assist carriers EV1 and EV2 may each be a shared electric assist bicycle (however, the present invention is not limited thereto). The user of the electric assist carrier EV1 charges the battery (not shown) of the electric assist carrier EV1 by using the pedaling force during traveling. The battery has sufficient power. Therefore, when the electric assist carrier EV1 arrives at the wireless charging platform 120, the user of the electric assist carrier EV1 can operate the control device 110_1 to provide the second command CMD2 to the control device 110_1. The wireless charging platform 120 calculates the battery energy PB contributed by the electric assist carrier EV1. The more the battery energy PB that the electric assist carrier EV1 can contribute, the more usage bonus BNS the user of the electric assist carrier EV1 receives. The usage bonus BNS can be used for discounts when the user rents the electric assist carrier EV1, discounts for the next rental of the electric assist carrier, and the like. In this way, the power management system 100 provides a new transaction method.

[0016] In this embodiment, when the platform power supply amount PP is less than or equal to the platform power supply upper limit PLM, the wireless charging platform 120 can provide the same or different power supply modes, such as a normal charging mode or a high-power overcharging mode, for the remaining power of the electric assist carriers EV1 and EV2.

[0017] For ease of explanation, in this embodiment, two control devices (i.e., control devices 110_1 and 110_2) and one wireless charging platform (i.e., wireless charging platform 120) are taken as examples. However, the present invention does not limit the number of control devices and the number of wireless charging platforms. In one embodiment, there may be more than two control devices of the present invention. In one embodiment, there may be a plurality of wireless charging platforms of the present invention.

[0018] In this embodiment, the wireless charging platform 120 may be any form of wireless charging station. The remote monitoring device 130 may be any form of electronic device having computing functions such as a server, a desktop computer, a notebook computer, and a smartphone. In this embodiment, the wireless charging platform 120 can communicate with the remote monitoring device 130 using a wired communication method or a wireless communication method well-known to those skilled in the art.

[0019] In this embodiment, since the control device 110_2 can also have the same functions and operations as the control device 110_1, they will not be repeated here.

[0020] Referring to FIG. 2, FIG. 2 is a schematic diagram of a power management system according to a second embodiment of the present invention. In the present embodiment, the power management system 200 includes control devices 210_1, 210_2, a wireless charging platform 220, and a remote monitoring device 230. The control devices 210_1, 210_2 are respectively provided in the electric assist carriers EV1, EV2. In the present embodiment, the control device 210_1 is provided in the electric assist carrier EV1. The control device 210_2 is provided in the electric assist carrier EV2.

[0021] In the present embodiment, the electric assist carrier EV1 includes a battery BTR and a motor MTR. The control device 210_1 includes a power control circuit 211, an identification code transmission circuit 212, an operation interface 213, a processor 214, a display 215, and a carrier communication circuit 216. The power control circuit 211 is connected to the battery BTR and the motor MTR. During the running of the electric assist carrier EV1, the power control circuit 211 drives the motor MTR using the battery energy PB of the battery BTR. During the running of the electric assist carrier EV1, the power control circuit 211 charges the battery BTR using the pedaling force.

[0022] During wireless communication between the control device 210_1 and the wireless charging platform 220, the power control circuit 211 charges the battery BTR using the wireless electrical energy PC from the wireless charging platform 220 in response to the first command CMD1. During wireless communication between the control device 210_1 and the wireless charging platform 220, the power control circuit 211 transmits the battery energy PB to the wireless charging platform 220 by wireless means in response to the second command CMD2.

[0023] In this embodiment, during wireless communication with the control device 210_1, the identification code transmission circuit 212 provides the identification code ID1 of the electric assist carrier EV1 to the wireless charging platform 220. Therefore, the wireless charging platform 220 can identify the electric assist carrier EV1 using the identification code ID1. The operation interface 213 is connected to the power control circuit 211. The operation interface 213 is operated to provide one of the first command CMD1 and the second command CMD2. The processor 214 is connected to the power control circuit 211 and the operation interface 213. The processor 214 receives one of the first command CMD1 and the second command CMD2 from the operation interface 213 and the power VB (i.e., remaining power) of the battery BTR from the power control circuit 211.

[0024] In this embodiment, the display 215 is connected to the processor 214. The display 215 displays the power VB of the battery BTR. Also, the display 215 can display information such as the wireless power supply state, wireless charging state, mileage, running time, rental cost, etc. of the electric assist carrier EV1 (however, the present invention is not limited thereto). The carrier communication circuit 216 is connected to the processor 214. During wireless communication between the control device 210_1 and the wireless charging platform 220, the carrier communication circuit 216 provides one of the first command CMD1 and the second command CMD2 and the power VB of the battery BTR to the wireless charging platform 220 by wireless means.

[0025] Processor 214 may be, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessor, digital signal processor (DSP), programmable controller, application specific integrated circuit (ASIC), programmable logic device (PLD), or other similar device capable of loading and executing a computer program, or a combination of these devices. Display 215 may be a display device that provides a display function such as a liquid crystal display (LCD), light-emitting diode (LED), organic light-emitting diode (OLED), etc. Also, the display employs a cold cathode fluorescent lamp (CCFL) or a light-emitting diode (LED) as the screen of the backlight module.

[0026] Power control circuit 211 includes a charge and discharge circuit 2111, a wireless power transmission circuit 2112, a sensing circuit 2113, and a controller 2114. The charge and discharge circuit 2111 is connected to battery BTR and motor MTR. The wireless power transmission circuit 2112 is connected to the charge and discharge circuit 2111. The sensing circuit 2113 senses the state of battery BTR. In this embodiment, the sensing circuit 2113 senses the power VB of battery BTR, the voltage value of battery energy PB, and the current value of battery energy PB via one of the charge and discharge circuit 2111 and the wireless power transmission circuit 2112. Also, the sensing circuit 2113 can sense the voltage value of wireless power PC and the current value of wireless power PC via one of the charge and discharge circuit 2111 and the wireless power transmission circuit 2112.

[0027] The controller 2114 is connected to the charge and discharge circuit 2111 and the wireless power transmission circuit 2112. During traveling, the controller 2114 controls the charge and discharge circuit 2111 such that the charge and discharge circuit 2111 drives the motor MTR using the battery energy PB of the battery BTR. During traveling, the controller 2114 controls the charge and discharge circuit 2111 such that the charge and discharge circuit 2111 charges the battery BTR using the pedaling force.

[0028] In the present embodiment, during wireless communication between the control device 210_1 and the wireless charging platform 220, the controller 2114 controls the charge and discharge circuit 2111 and the wireless power transmission circuit 2112 in response to one of the first command CMD1 and the second command CMD2.

[0029] In response to the first command CMD1, the controller 2114 controls the charge and discharge circuit 2111 and the wireless power transmission circuit 2112 such that the power control circuit 211 charges the battery BTR using the wireless power PC. More specifically, the wireless power transmission circuit 2112 is, for example, a coil circuit. The charge and discharge circuit 2111 includes, for example, a conversion circuit of a plurality of power switches. When receiving the first command CMD1, the controller 2114 controls the wireless power transmission circuit 2112 to receive the wireless power PC, and controls the charge and discharge circuit 2111 to convert the wireless power PC into charging power PC'. The wireless power PC is AC power. When receiving the first command CMD1, the charge and discharge circuit 2111 rectifies the wireless power PC using the operation of the plurality of power switches, generates the charging power PC', and provides the charging power PC' to the battery BTR. For example, in response to the first command CMD1, the controller 2114 controls the charge and discharge circuit 2111 as a full-bridge rectifier circuit.

[0030] In response to the second command CMD2, the controller 2114 controls the charge and discharge circuit 2111 and the wireless power transmission circuit 2112, and the power control circuit 211 transmits the battery energy PB to the wireless charging platform 220 by wireless means. More specifically, when receiving the second command CMD2, the controller 2114 controls the wireless power transmission circuit 2112 to receive the battery energy PB, and controls the charge and discharge circuit 2111 to convert the battery energy PB into wireless power PB'. The wireless power PB' is AC power. When receiving the first command CMD1, the charge and discharge circuit 2111 rectifies the wireless power PC using the operation of a plurality of power switches, generates the wireless power PB', and provides the wireless power PB' to the wireless power transmission circuit 2112. For example, the controller 2114 controls the charge and discharge circuit 2111 as a power inverter in response to the first command CMD1. The wireless power transmission circuit 2112 transmits the wireless power PB' to the wireless charging platform 220 by wireless means.

[0031] In addition, the controller 2114 determines the power VB of the battery BTR. If it is lower than the set value of the power VB of the battery BTR, it indicates that the power VB is insufficient. Therefore, the controller 2114 controls the charge and discharge circuit 2111 to stop the conversion of the battery energy PB into the wireless power PB'.

[0032] In this embodiment, the wireless charging platform 220 includes a platform power control circuit 221, an identification code receiving circuit 222, a platform communication circuit 223, and a platform processor 224. The platform power control circuit 221 is connected to the external electrical energy PE. During wireless communication between the control device 210_1 and the wireless charging platform 220, in response to the first command CMD1, the platform power control circuit 221 wirelessly supplies power to the battery BTR using the external electrical energy PE in a wireless manner. During wireless communication between the control device 210_1 and the wireless charging platform 220, in response to the second command CMD2, the platform power control circuit 221 wirelessly supplies power to at least one of the other electric assist carriers (such as the electric assist carrier EV2) using the wireless electrical energy PB' from the power control circuit 211.

[0033] In this embodiment, the identification code receiving circuit 222 receives the identification codes of the electric assist carriers EV1 and EV2. Taking this embodiment as an example, when the electric assist carrier EV1 enters the wireless charging area of the wireless charging platform 220, the identification code receiving circuit 222 can receive the identification code ID1 transmitted by the identification code transmitting circuit 212. Therefore, the wireless charging platform 220 can identify the electric assist carrier EV1 using the identification code ID1 and know that the electric assist carrier EV1 has entered the wireless charging area. In this embodiment, the identification code transmitting circuit 212 may provide the identification code ID1 to the identification code receiving circuit 222 using, for example, radio-frequency identification (RFID) technology (however, the present invention is not limited thereto).

[0034] In this embodiment, the platform communication circuit 223 receives, by a wireless method, one of the first command CMD1 and the second command CMD2 and the power VB of the battery BTR. The platform communication circuit 223 wirelessly communicates with the carrier communication circuit 216 to receive one of the first command CMD1 and the second command CMD2 and the power VB of the battery BTR. The platform communication circuit 223 can wirelessly communicate with the carrier communication circuit 216, for example, by using the ZigBee network protocol (however, the present invention is not limited thereto).

[0035] The platform processor 224 is connected to the platform power control circuit 221 and the platform communication circuit 223. The platform processor 224 controls the platform power control circuit 221 based on one of the first command CMD1 and the second command CMD2. The platform power control circuit 221 performs a power supply operation in response to the control of the platform processor 224. In this embodiment, the platform power control circuit 221 includes a bidirectional electric energy conversion circuit 2211, a wireless electric energy transmission circuit 2212, a sensing circuit 2213, and a platform controller 2214. The bidirectional electric energy conversion circuit 2211 is connected to the external electric energy PE. The wireless electric energy transmission circuit 2212 is connected to the bidirectional electric energy conversion circuit 2211. The sensing circuit 2213 senses the platform power supply amount PP of the platform power control circuit 221. In this embodiment, the sensing circuit 2213 can sense the platform power supply amount PP via one of the bidirectional electric energy conversion circuit 2211 and the wireless electric energy transmission circuit 2212. Further, the platform processor 224 can provide a usage bonus BNS corresponding to the electric assist carrier EV1 based on the wireless electric energy PB'.

[0036] In this embodiment, the platform processor 224 may be, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessor, digital signal processor (DSP), programmable controller, application specific integrated circuits (ASIC), programmable logic device (PLD), or other similar devices capable of loading and executing a computer program, or a combination of these devices.

[0037] The platform controller 2214 is connected to the platform processor 224, the bidirectional electrical energy conversion circuit 2211, and the wireless electrical energy transmission circuit 2212. In response to the first command CMD1, the platform controller 2214 controls the bidirectional electrical energy conversion circuit 2211 to convert the external electrical energy PE into the charging electrical energy PC, controls the wireless electrical energy transmission circuit 2212, and provides the charging electrical energy PC to the control device 210_1. The wireless electrical energy transmission circuit 2212 is, for example, a coil circuit.

[0038] In response to the second command CMD2, the platform controller 2214 controls the wireless electrical energy transmission circuit 2212 to receive the wireless electrical energy PB'. Also, the wireless electrical energy transmission circuit 2212 uses the wireless electrical energy PB' to perform wireless power supply to at least one of the other electric assist carriers (such as the electric assist carrier EV2).

[0039] Furthermore, the platform controller 2214 also determines the power VB of the battery BTR. When the power VB of the battery BTR is lower than the set value, it indicates that the power VB is insufficient. Therefore, the platform controller 2214 controls the wireless power transmission circuit 2212 to stop receiving the wireless power PB'.

[0040] In this embodiment, the sensing circuit 2213 can provide the platform power supply amount PP to the platform processor 224. The platform communication circuit 223 can further provide the platform power supply amount PP from the platform processor 224 to the remote monitoring device 230 by wireless means. The remote monitoring device 230 determines the platform power supply amount PP. When the platform power supply amount PP is greater than the platform power supply upper limit PLM, the remote monitoring device 230 notifies the wireless charging platform 220 using the notification signal SN. For example, the remote monitoring device 230 transmits the notification signal SN to the platform communication circuit 223. The platform processor 224 receives the notification signal SN and knows from the notification signal SN that the current platform power supply amount PP is too high. Therefore, the platform processor 224 controls the platform power control circuit 221 to reduce the load. Therefore, the platform power supply amount PP decreases.

[0041] In summary, the power management system of the present invention can control the power supply operation of the wireless charging platform based on the remaining power and the upper limit of the platform power supply amount. Further, the wireless charging platform can perform wireless power supply to at least one of the other electric assist carriers using the battery energy of the first electric assist carrier. In this way, the power management system can provide an energy-saving and efficient wireless power management mechanism. In addition, the wireless charging platform can provide a usage bonus corresponding to the electric assist carrier based on the battery energy received by the wireless charging platform itself. The more battery energy that the electric assist carrier can contribute, the more usage bonus received from the user of the electric assist carrier. In this way, the power management system provides a novel trading method.

[0042] As described above, the present invention has been disclosed through the embodiments, but these are not intended to limit the present invention. Those with ordinary knowledge in the related technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the appended claims.
