Abstract

Disclosed herein is a battery device (100), including a battery cell assembly (20) and a sampling assembly (80). The battery cell assembly (20) includes a plurality of battery cells (30) sequentially connected in series. The sampling assembly (30) includes a plurality of sampling parts, a plurality of connection wire harnesses (70), and an output port (921). Each sampling part is electrically connected to at least one connection wire harness (70), a plurality of the connection wire harnesses (70) are all connected to the output port (921). The plurality of sampling parts include a first sampling part (81) and a second sampling part (82). The first sampling part (81) and the second sampling part (30) are provided with a sampling point that can be electrically connected to the series path of the battery cells (30). The number of the first sampling parts (81) is two, and the two first sampling parts (81) are separately and electrically connected to the battery cell (30) at the front and the battery cell (30) at the rear of a plurality of the battery cells (30) sequentially connected in series. In the series path of a plurality of the battery cells (30), the number of the battery cells (30) between the sampling points of at least two adjacent second sampling parts (82) is greater than or equal to two.
