Abstract: A solar cell unit comprises a cell. The cell includes a cell substrate and a plurality of secondary grid lines disposed on a front surface of the cell substrate. The secondary grid lines comprises an edge secondary grid line adjacent to an edge of the cell substrate and a middle secondary grid line disposed inside of the edge secondary grid line. The secondary grid line comprises a welding portion. At least one welding portion of the edge secondary grid line has a projection area in the cell substrate larger than a welding portion of the middle secondary grid line. The solar cell unit also comprises a plurality of conductive wires spaced apart from each other and welded with the secondary grid lines in the welding portion.

Abstract: A power battery assembly may include a battery circuit and a circuit protecting unit. The circuit protecting unit may be connected in series with the battery circuit. The circuit protecting unit may include a relay and a current sensing unit connected in series with the battery circuit. A switching unit is connected with the relay for controlling the switching of the relay, and a controller is connected with the switching unit and to the current sensing unit to control switching on or switching off the switching unit based on comparison of the current value detected by the current sensing unit, and sent to the controller with a first predetermined current value.
