The battery 30 is coupled to the power integration circuit 20 .

圖1所示的電源整合系統係為雙向架構，因此電源整合電路20接收直流電源裝置40提供的直流電源，且電源整合電路20的充電器22轉換直流電源對電池30充電，因此直流電源裝置40可對電池30進行充電。在本實施例中，直流電源裝置40係為，但不限制為USB-PD。以輕型電動載具－電動腳踏車為例，馬達10、電源整合電路20以及電池30設置於電動腳踏車的車體內部，並且直流電源裝置40提供的直流電源為外部的USB-PD直流電源。因此，當電動腳踏車插接USB-PD直流電源進行充電時，電源整合電路20的充電器22轉換USB-PD直流電源，然後對設置於車體內部的電池30充電。The power integration system shown in FIG. 1 is a bidirectional architecture, so the power integration circuit 20 receives the DC power provided by the DC power supply device 40, and the charger 22 of the power integration circuit 20 converts the DC power to charge the battery 30, so the DC power supply device 40 The battery 30 can be charged. In this embodiment, the DC power supply device 40 is, but not limited to, a USB-PD.

As mentioned above, the power receiving device 50 is, but not limited to, a portable mobile device (such as a mobile phone, a tablet computer, a notebook computer, etc.). When the user is riding an electric bicycle outdoors, and at the same time plugs the mobile phone (that is, the power receiving device 50) into the charger 22 of the power integration circuit 20 for charging, the battery 30 provides the power required by the mobile phone through the charger 22 to charge it.

此外，電池30透過變頻器21提供驅動馬達10所需的電力。當使用者在戶外騎乘電動腳踏車，驅動馬達10所需的電力則透過電池30所供電。In addition, the battery 30 provides the power required to drive the motor 10 through the frequency converter 21 . When the user rides the electric bicycle outdoors, the power required to drive the motor 10 is supplied by the battery 30 .

此外，受電裝置50透過充電器22對電池30充電。在電動腳踏車非為騎乘的狀態，且無直流電源裝置40提供的直流電源(USB-PD直流電源)對電池30充電時，可透過受電裝置50(手機)提供其電力對電池30進行充電，以提供電動腳踏車短時間的騎乘。舉例來說，當使用者在戶外騎乘電動腳踏車時，發生電池30無法提供電動腳踏車所需的電力時，則可透過受電裝置50提供其電力對電池30進行充電，以提供電動腳踏車短時間的騎乘至就近具有直流電源裝置40的場域進行充分地充電。In addition, the power receiving device 50 charges the battery 30 through the charger 22 . When the electric bicycle is not in a riding state, and there is no DC power supply (USB-PD DC power supply) provided by the DC power supply device 40 to charge the battery 30, the battery 30 can be charged through the electric power provided by the power receiving device 50 (mobile phone). To provide short-time riding of electric bicycles. For example, when the user is riding an electric bicycle outdoors, when the battery 30 cannot provide the electric power required by the electric bicycle, the power receiving device 50 can be used to provide the electric power to charge the battery 30 to provide short-term power for the electric bicycle. Ride to the nearest field with DC power supply device 40 to fully charge.

綜上說明，圖1所示的電源整合系統提供雙向的電源路徑，包括直流電源裝置40對電池30進行充電或受電裝置50對電池30充電，以及電池30對受電裝置50進行供電或電池30對馬達10進行供電。To sum up, the power integration system shown in FIG. 1 provides a bidirectional power path, including the DC power supply device 40 charging the battery 30 or the power receiving device 50 charging the battery 30, and the battery 30 supplying power to the power receiving device 50 or the battery 30 pairing The motor 10 supplies power.
