Description

Technical Field

[0001] This utility model belongs to the field of automotive lead-acid battery technology, specifically relating to an automotive battery cover structure. Background Technology

[0002] Lead-acid batteries are classified into industrial, automotive, and power types. Among them, automotive lead-acid batteries are divided into starved lead-acid batteries and flooded lead-acid batteries. Starved lead-acid batteries are suitable for vehicles with automatic start-stop systems and are more suitable for models that frequently use batteries. The batteries are generally placed in the engine compartment or trunk of the car. Most of the parts in the car are made of materials such as fur and steel. Because the electrolyte used inside the lead-acid batteries in cars is sulfuric acid, there will be a venting phenomenon during use in order to maintain the normal internal pressure of the battery. During the venting process, acid mist will be discharged, which poses a risk of corrosion to the components inside the car. Utility Model Content
