Title:
SAMPLING APPARATUS, BATTERY, AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/143013
Kind Code:
A1
Abstract:
A sampling apparatus (100), a battery, and an electrical device. The sampling apparatus (100) comprises a sampling circuit board (110), the sampling circuit board (110) has a first sampling line (111) and a second sampling line (112), and the first sampling line (111) and the second sampling line (112) are used for collecting different operating parameters of a battery module; a surface of at least one of the first sampling line (111) and second sampling line (112) is provided with a continuous or discontinuous protection layer; a signal output portion (113) is provided on the sampling circuit board (110), and the first sampling line (111) and the second sampling line (112) are each connected to the signal output portion (113). The surface of at least one of the first sampling line (111) and the second sampling line (112) is completely provided with a protective layer, making it so that, of the first sampling line (111) and second sampling line (112), at least a sampling circuit used for collecting temperature signals has a protective layer formed over the entire surface thereof, the protective layer satisfying the oxidation resistance requirements of the sampling circuit. The method for the surface treatment of the entire sampling circuit is not limited by the structure of a connecting part, thus avoiding the problem that the complexity of the treatment process is increased due to limitations from the structure of the connecting part.
