1. Liquid vent plug Introduction
Battery Liquid Vent Plug is a key safety component in the battery management system. It is mainly used to regulate the internal pressure of the battery and discharge the gas generated by the decomposition of the electrolyte, while preventing external pollutants from entering. It is widely used in lead-acid batteries, lithium-ion batteries and other liquid electrolyte batteries to ensure the safety and stability of the battery during the charge and discharge process.
2. Battery Liquid vent plug Core functions
Pressure regulation: When the battery is overheated or overcharged, the internal electrolyte may gasify and cause the pressure to rise. The vent plug prevents the battery from expanding or exploding through controlled pressure relief.
Gas emission: Release hydrogen, oxygen and other electrolytic products (especially lead-acid batteries) to avoid the risk of gas accumulation.
Liquid sealing: Special designs (such as labyrinth channels or hydrophobic membranes) allow gas to be discharged but block electrolyte leakage, reducing corrosion and loss.

3. Battery Liquid vent plug Technical features and innovations
Material selection: Acid- and alkaline-resistant materials (such as PP) ensure long-term use in corrosive environments.
Smart valve design: Some high-end models use spring valves or temperature-controlled diaphragms, which only open when the threshold pressure is reached to improve safety.
Environmental compatibility: RoHS-compliant and adaptable to the sustainable development needs of the new energy industry.
Integrated sensors: The new smart exhaust plug can integrate pressure/temperature sensors, and real-time data is fed back to the battery management system (BMS).
4. Application scenarios
Automotive batteries: traditional fuel vehicle lead-acid batteries, electric vehicle lithium battery packs.
Energy storage system: large battery modules for photovoltaic/wind energy storage power stations.
Industrial equipment: forklifts, UPS backup power supplies, etc.
5. Maintenance and selection recommendations
Regular inspection: Clogged exhaust plugs will cause battery bulging and need to be cleaned or replaced.
Adaptability: Select the corresponding air permeability specifications according to the battery type (such as AGM, EFB).
Installation direction: Make sure the exhaust hole is facing upward or installed according to the logo to avoid liquid backflow.
