Title:
SYSTEM FOR ENERGY FEEDBACK CHARGING ENERGY-SAVING OPERATION AND EMERGENCY OPERATION CONTROL
Document Type and Number:
WIPO Patent Application WO/2019/080149
Kind Code:
A1
Abstract:
A system for energy feedback charging energy-saving operation and emergency operation control, comprising an energy feedback unit, an uninterruptible power source (UPS) control unit, a charging and discharging control unit, a storage battery, a direct current/alternating current inverter, a power supply switching circuit, a device control unit and a driving unit; the energy feedback unit charges the storage battery when an electric motor is in an electric brake regeneration state; the charging and discharging control unit feeds back the power state of the storage battery to the UPS control unit; the UPS control unit controls the direct current/alternating current inverter to convert the direct current power supply of the storage battery into an alternating current supply power output, and monitors the input/output state of the direct current/alternating current inverter in real time; the UPS control unit feeds back the current working state to the device control unit according to the work of controlling the charging and discharging control unit and the direct current/alternating current inverter; the UPS control unit controls the power supply switching circuit to use a mains power supply or the storage battery to supply power. The system has the advantages of being environmentally friendly, and may continuously supply power when mains power experiences an outage.
