The invention relates to a movable portable power battery charging and V2G device. A PC control system, a PCS power unit and a direct-current contactor are integrated in a cabinet; the PC control system, the PCS power unit, the direct-current contactor and a power battery pack form a charging and discharging loop; the PCS power unit collects circuit parameters of the charging and discharging loop;when the PC control system receives a charging mode, the PC control system reads input charging parameters, judges whether the charging-discharging loop is abnormal based on the circuit parameters; when the charging-discharging loop is abnormal, the PC control system outputs protection alarm information to the direct-current contactor so as to disconnect the direct-current contactor; when the charging-discharging loop is normal, the PC control system calculates estimated charging time based on the charging parameters, controls the direct-current contactor to be conducted, controls the PCS power unit to convert alternating current of a power grid into direct current to charge the power battery pack, continuously judge whether the SOC reaches a first set threshold value or not, and controlsthe direct-current contactor to be disconnected to stop charging if the SOC reaches the first set threshold value.
本发明可移动便携式动力电池充电与V2G装置,机柜内集成有PC控制系统、PCS功率单元和直流接触器,PC控制系统、PCS功率单元、直流接触器和动力电池组构成充放电回路;PCS功率单元采集充放电回路的电路参数;PC控制系统在收到充电模式时,读取输入的充电参数,基于电路参数判断充放电回路是否异常,在出现异常时输出保护告警信息至直流接触器以断开直流接触器,在未出现异常时基于充电参数计算预估充电时间,控制直流接触器导通,控制PCS功率单元将电网的交流电转换为直流电为动力电池组充电,不断判断SOC是否达到第一设定阈值,在为是时控制直流接触器断开停止充电。
