Abstract: An adapter module, a battery module, a battery pack, and a vehicle. The adapter module comprises a support member, a low-voltage plug member, a sampling assembly, and an electrode lead-out piece. The low-voltage plug member is provided on the support member. One end of the sampling assembly is provided on the support member; the described end of the sampling assembly is electrically connected to the low-voltage plug member; and the sampling assembly, is used for voltage sampling and/or temperature sampling. The electrode lead-out piece is provided on the support member, is spaced apart from the low-voltage plug member, and is electrically connected to the described end of the sampling assembly.

Abstract: A high speed silent cracking agent of the liquid-soaked type consists of a cartridge of solid cracking agent and a solution of liquid inhibitor catalyst. The cartridge of solid cracking agent contains about 50 to about 90 percent by weight of quicklime, about 1 to about 4 percent by weight of borax, about 8 to about 30 percent by weight of vermiculite, 0 to 2 percent by weight of aluminum powder, and 0 to about 14 percent by weight of sulphur based on the total weight of said solid cracking agent. The solution of liquid inhibitor catalyst contains about 0.05 to about 0.40 percent by weight of caustic soda, about 0.01 to about 0.50 percent by weight of quartz, about 0.04 to about 0.30 percent by weight of ammoniation agent and about 99.8 to about 98.8 percent by weight of water, or contains about 0.40 to about 1.80 percent by weight sodium silicate, about 0.05 to about 0.40 percent by weight of ammoniation agent and about 99.55 to about 97.
