摘要：【中文】本发明涉及一种能量双向流动节能装置及其能量双向流动控制方法，其特点是该装置由蓄电池、能量双向流动DC/DC变换器、开关1‑4和控制电路组成。当开关1、3闭合时，能量通过DC/DC变换器向负载供电；当开关1、4闭合时，能量从高压侧向低压侧流动时，输入电源通过DC/DC变换器给蓄电池充电，能量从低压侧流向高压侧时，蓄电池放电通过DC/DC变换器反馈回输入端；当开关2、3闭合时，蓄电池作为供电电源通过DC/DC变换器向负载供电。本发明适用场合多，控制灵活度高、结构简单，造价低。 【EN】The invention relates to an energy bidirectional flow energy-saving device and an energy bidirectional flow control method thereof, which are characterized in that the device consists of a storage battery, an energy bidirectional flow DC/DC converter, switches 1-4 and a control circuit. When the switches 1, 3 are closed, energy is supplied to the load through the DC/DC converter; when the switches 1 and 4 are closed, when energy flows from the high-voltage side to the low-voltage side, the input power supply charges the storage battery through the DC/DC converter, and when the energy flows from the low-voltage side to the high-voltage side, the storage battery discharges and is fed back to the input end through the DC/DC converter; when the switches 2, 3 are closed, the battery serves as a power supply source to supply power to the load through the DC/DC converter. The invention has the advantages of multiple application occasions, high control flexibility, simple structure and low manufacturing cost.
