A battery swap station cabinet comprises an AC-DC converter, a plurality of charging and discharging DC converters, a plurality of batteries, a first auxiliary DC converter and a mainboard. The AC-DC converter receives a three-phase AC power supply and converts the three-phase AC power supply into a DC bus voltage. The plurality of charging and discharging direct current converters respectively receive the direct current bus voltage and convert the direct current bus voltage into a plurality of direct current voltages. The plurality of batteries are correspondingly connected with the charging and discharging DC converters and receive the DC voltages. The first auxiliary DC converter receives a DC bus voltage and converts the DC bus voltage into a first state voltage. The mainboard receives the first state voltage and the second state voltage. According to the state of the three-phase AC power supply, the mainboard outputs the first state voltage or the second state voltage to the batteries so as to maintain the power required by the uninterruptible power operation of the batteries. The invention also relates to an AC discharge cabinet and a charging station system.
一种换电站机柜包括交流对直流转换器、复数充放电直流转换器、复数电池、第一辅助直流转换器以及主板。交流对直流转换器接收三相交流电源,且转换三相交流电源为直流母线电压。复数充放电直流转换器分别接收直流母线电压,且转换直流母线电压为复数直流电压。复数电池对应地连接该等充放电直流转换器,且接收该等直流电压。第一辅助直流转换器接收直流母线电压,且转换直流母线电压为第一状态电压。主板接收第一状态电压与第二状态电压。根据三相交流电源状态,主板输出第一状态电压或第二状态电压至该等电池,以维持该等电池不断电操作所需的电力。本公开还涉及一种交流放电机柜以及一种充电站系统。
