This Battery Pack Nail Penetration Tester is designed for two types of testing:
- Bottom Sphere Impact Test of Power Battery Packs or Systems: to evaluate and assess the safety performance of battery products under Bottom Sphere Impact test conditions.
- Bottom Nail Penetration Trigger Test of a Single Cell in a Power Battery Pack: to observe thermal propagation to adjacent cells after triggering thermal runaway in a single cell, thereby assessing the overall safety performance of the battery pack.
Equipment Installation Requirements
- Placement and Positioning: The Battery Pack Nail Penetration Tester can be offloaded using a 5-ton extended-reach forklift. After moving it into the laboratory, ensure the rear and both sides of the equipment are at least 1000 mm from the walls, and the front operating space is at least 3500 mm to allow easy loading and unloading of battery packs. After positioning, secure the equipment and connect the power and grounding lines. (A forklift or overhead crane is required for battery pack installation.)
- Floor Load Capacity: The floor must support a minimum of 1500 kg/m².
- Laboratory Environment: The laboratory should be equipped with a ventilation system capable of exhausting smoke generated during testing. Adequate lighting is required to observe and operate the equipment clearly.
- Accessibility and Safety: Laboratory aisles must allow convenient transport of batteries and related handling equipment. In the event of an emergency, personnel should be able to evacuate promptly.
- Fire Safety Equipment: The laboratory must be equipped with appropriate firefighting facilitiesthat are easily accessible for use, such as fire hoses and extinguishers.
- Material Handling: An overhead crane must be available in the laboratory to facilitate the loading and unloading of battery packs.
