Adapter module, battery module, battery pack, and vehicle

Abstract

The adapter module (1), the battery module (2), the battery pack (3), and the vehicle (4). The adapter module (1) includes a support member (10), a low-voltage plug member (20), a sampling assembly (30), and an electrode lead piece (40). The low-voltage plug member (20) is provided on the support member (10). One end of the sampling assembly (30) is provided on the support member, and the illustrated end of the sampling assembly (30) is electrically connected to the low-voltage plug member (20), and the sampling assembly (30) is used for voltage sampling and / or temperature sampling. The electrode lead piece (40) is provided on the support member (10), is spaced from the low-voltage plug member (20), and is electrically connected to the illustrated end of the sampling assembly (30).
