Description

Technical Field

[0002] The basic characteristic of valve-regulated lead-acid batteries is that they do not require acid or water maintenance during use. The battery has a sealed structure and will not leak acid or emit acid mist. A one-way exhaust valve (also called a safety valve) is provided on the battery cover. The function of this valve is that when the amount of gas inside the battery exceeds a certain value (usually expressed as an air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve automatically opens to discharge the gas, and then automatically closes to prevent air from entering the battery.

[0003] The shell of a lead-acid battery is one of the core components of a battery module. The interior of the shell forms a space for accommodating the battery. Existing lead-acid batteries and shells are mostly integrated or fixed by bolts, which makes it inconvenient to quickly disassemble and assemble the battery for maintenance, and the heat dissipation performance is poor, which can cause the plate to be damaged due to overheating expansion and the shell to deform.
