When the switch unit 2 is in the battery charging mode, the second one-way electric control switch 23 is in a closed circuit state, and the relay 21, the first one-way electric control switch 22 and the third one-way electric control switch 24 are in an open circuit state, so that the power supply positive terminal 811 is electrically connected to the battery positive terminal 821, and the power supply negative terminal 812 is electrically connected to the battery negative terminal 822, so that the DC power supply module 81 charges the battery 82.
[共同供電模式] [Shared power supply mode]
當該控制單元3自該電供電流偵測模組13接收該電供電流值訊號，並判斷該電供電流值訊號小於該負載電流值時，代表當下該直流電源供應模組81的供給能力受限，無法達到該負載電流值的要求，故驅動該開關單元2切換至該共同供電模式。該開關單元2 於該共同供電模式時，該第一單向電控開關22與該繼電器21呈閉路狀態，該第二單向電控開關23與該第三單向電控開關24呈開路狀態，以使該電供正端811、該電池正端821及該轉換器正端831呈電連接，且該電供負端812、該電池負端822及該轉換器負端832呈電連接，以由該直流電源供應模組81及該電池82共同輸出電能。值得一提的是，該電池82的輸出電流的上限會被該電池電流偵測模組12限制，避免該直交流轉換器83接收到的功率過大而損毀。 When the control unit 3 receives the power supply current value signal from the power supply current detection module 13 and determines that the power supply current value signal is less than the load current value, it means that the supply capacity of the DC power supply module 81 is limited and cannot meet the load current value requirement, so the switch unit 2 is driven to switch to the common power supply mode. The switch unit 2 In the common power supply mode, the first one-way electric control switch 22 and the relay 21 are in a closed circuit state, and the second one-way electric control switch 23 and the third one-way electric control switch 24 are in an open circuit state, so that the power supply positive terminal 811, the battery positive terminal 821 and the converter positive terminal 831 are electrically connected, and the power supply negative terminal 812, the battery negative terminal 822 and the converter negative terminal 832 are electrically connected, so that the DC power supply module 81 and the battery 82 jointly output electrical energy. It is worth mentioning that the upper limit of the output current of the battery 82 will be limited by the battery current detection module 12 to prevent the DC-AC converter 83 from receiving too much power and being damaged.
另外，由於每一交流電網96所提供的計費區間存在上、下限值，每當該交流功率值訊號超過上限值且持續一定時間，則需加收一定費用。因此，當該伺服器98判斷該交流功率值訊號大於一預先儲存的需量上限管控功率值(即上限值)時，傳送一管控訊號至該控制單元3。當該控制單元3接收到該管控訊號時，驅動該開關單元2切換至該共同供電模式，調取該電池82的電能以降低自該交流電網96汲取電能，盡可能地避免該交流功率值訊號超過該需量上限管控功率值，連帶產生降低成本的效果。 In addition, since the billing interval provided by each AC power grid 96 has an upper and lower limit, whenever the AC power value signal exceeds the upper limit and lasts for a certain period of time, a certain fee will be charged. Therefore, when the server 98 determines that the AC power value signal is greater than a pre-stored demand upper limit control power value (i.e., the upper limit), a control signal is transmitted to the control unit 3. When the control unit 3 receives the control signal, it drives the switch unit 2 to switch to the common power supply mode, and calls the power of the battery 82 to reduce the power drawn from the AC power grid 96, so as to avoid the AC power value signal exceeding the demand upper limit control power value as much as possible, thereby reducing costs.
值得一提的是，僅於該共同供電模式時使該繼電器21呈閉路狀態。於該電源供電模式、該電池供電模式及該電池充電模式時則使該繼電器21呈開路狀態，以確保該電池負端822與該電供負端812間不會由該繼電器21維持電連接。 It is worth mentioning that the relay 21 is in a closed circuit state only in the common power supply mode. In the power supply mode, the battery power supply mode and the battery charging mode, the relay 21 is in an open circuit state to ensure that the battery negative terminal 822 and the power supply negative terminal 812 are not electrically connected by the relay 21.
[中斷模式] [Interrupt Mode]
當該控制單元3自該電池電流偵測模組12接收該電池電流值訊號，並判斷該電池電流值訊號小於該停止充電電流值時；亦或是當該控制單元3自該電池電壓偵測模組11接收該電池電壓值訊號，並判斷該電池電壓值訊號小於該停止放電電壓值時；又或是當該控制單元3自該溫度感測單元4接收該環境溫度值訊號，並判斷該環境溫度值訊號高於該風險溫度值時，驅動該開關單元2切換至該中斷模式。該開關單元2於該中斷模式時，該繼電器21、該第一單向電控開關22、該第二單向電控開關23及該第三單向電控開關24皆呈開路狀態。 When the control unit 3 receives the battery current value signal from the battery current detection module 12 and determines that the battery current value signal is less than the stop charging current value; or when the control unit 3 receives the battery voltage value signal from the battery voltage detection module 11 and determines that the battery voltage value signal is less than the stop discharging voltage value; or when the control unit 3 receives the ambient temperature value signal from the temperature sensing unit 4 and determines that the ambient temperature value signal is higher than the risk temperature value, the switch unit 2 is driven to switch to the interrupt mode. When the switch unit 2 is in the interruption mode, the relay 21, the first one-way electric control switch 22, the second one-way electric control switch 23 and the third one-way electric control switch 24 are all in an open circuit state.
值得一提的是，如遇到突發停電等情事，該配電盤95失去效力時，該自動切換開關93會自行中斷該緊急負載94與該配電盤95間的電連接，轉而使該緊急負載94與該備援直交流轉換器92間呈電連接，使得該緊急負載94得以利用該電池82儲備的電力達到不斷電的效果。 It is worth mentioning that if there is a sudden power outage and the switchboard 95 loses its effectiveness, the automatic switching switch 93 will automatically disconnect the electrical connection between the emergency load 94 and the switchboard 95, and instead connect the emergency load 94 to the backup DC-AC converter 92, so that the emergency load 94 can use the power stored in the battery 82 to achieve an uninterrupted power supply effect.
因此，本發明混合型供電調節系統藉由該控制單元驅動並切換該開關單元的該繼電器21、該第一單向電控開關22、該第二單向電控開關23及該第三單向電控開關24，以選擇由該直流電源供應模組81或該電池82輸出電能，進而產生穩定供給電能及調節電能的效果。 Therefore, the hybrid power supply regulation system of the present invention drives and switches the relay 21, the first one-way electric control switch 22, the second one-way electric control switch 23 and the third one-way electric control switch 24 of the switch unit by the control unit to select the DC power supply module 81 or the battery 82 to output power, thereby producing the effect of stable power supply and power regulation.
更精確地說，本實施例藉由該控制單元3驅動並切換該開 關單元2的該繼電器21、該第一單向電控開關22、該第二單向電控開關23及該第三單向電控開關24，而於該電源供電模式、該電池供電模式、該電池充電模式、該共同供電模式及該中斷模式間切換，選擇由該直流電源供應模組81及/或該電池82輸出電能，或是由該直流電源供應模組81為該電池82進行充電，進而產生穩定供給電能、易於調節電能及降低成本的效果。 More specifically, the control unit 3 drives and switches the relay 21, the first one-way electric control switch 22, the second one-way electric control switch 23 and the third one-way electric control switch 24 of the switch unit 2, and switches between the power supply mode, the battery supply mode, the battery charging mode, the common power supply mode and the interruption mode, and selects the DC power supply module 81 and/or the battery 82 to output power, or the DC power supply module 81 to charge the battery 82, thereby producing the effects of stable power supply, easy power regulation and cost reduction.
