SAMPLING DEVICE, BATTERY AND POWER CONSUMING APPARATUS
The present application provides a sampling device, a battery and a power consuming apparatus. The sampling device includes a sampling circuit board. The sampling circuit board has a first sampling wire and a second sampling wire. The first sampling wire and the second sampling wire are configured to acquire different working parameters of a battery module. A continuous or discontinuous protective layer is provided on a surface of at least one of the first sampling wire and the second sampling wire, and the first sampling wire and the second sampling wire are both connected to a signal output portion provided on the sampling circuit board. In the present application, the way of surface treatment for the entire sampling line is not limited by the structure of a connection portion, thereby avoiding the problem of an increased complexity of a treatment process due to the structural limitation of the connection portion.
