    摘要： A portable power electronic switching apparatus may include an input end high-voltage connector, a DC-DC converter circuit, an input end transfer switch, a first inverter circuit, a direct-current output end high-voltage connector, an alternating-current output end high-voltage connector, and a conversion controller, where the input end high-voltage connector may be connected to an input end of the DC-DC converter circuit, an output end of the DC-DC converter circuit may be separately connected to an input end of the first inverter circuit and the direct-current output end high-voltage connector by using the input end transfer switch. An output end of the first inverter circuit may be connected to the alternating-current output end high-voltage connector. The conversion controller may be connected to the first inverter circuit by using a first switch drive circuit, and the conversion controller may be connected to the DC-DC converter circuit by using a transformation ratio switch controller and a second switch drive circuit separately.

    摘要： A power battery pack may include several pouch or hard-shelled electrochemical cells. A safety structure for the power battery pack may include an expansion absorption layer, a supporting and fixing tray, an upper module press plate, a lower module bottom plate, and the like. There are multiple supporting and fixing trays and multiple expansion absorption layers. The multiple supporting and fixing trays are sequentially disposed from top to bottom layer by layer. One single electrochemical cell is disposed in each of the supporting and fixing trays. One expansion absorption layer is laid on a top surface of each single electrochemical cell. The upper module press plate is disposed in a manner of covering the topmost supporting and fixing tray. The lower module bottom plate is disposed on a bottom surface of the bottommost supporting and fixing tray. A strain sensor is disposed in the center of a top surface of the topmost single electrochemical cell. The strain sensor is connected to a battery management system (BMS) control board.
