Battery Impact Tester
The Battery Impact Testing Machine is a critical device designed to evaluate the safety and durability of batteries under simulated impact conditions. It complies with international standards like IEC 62133, UL 1642, and GB/T 31467.3, ensuring reliable test results for global certification.
Applicable Standards
- Global Compliance: Aligns with IEC 62133 (portable batteries), UL 1642 (lithium batteries), and GB/T 31467.3 (EV batteries).
- Multi-Scenario Testing: Supports impact simulations for transport, handling, and misuse scenarios.

Working Principle
The machine operates via free-fall impact testing, where a weighted pendulum strikes a battery at a predefined height. A PLC control system adjusts parameters like drop height and weight, while sensors capture real-time data on force, voltage, and temperature. The test chamber is equipped with anti-vibration mounts to isolate external interference.
Test Principle
- Setup: Fully charged batteries are secured on a platform with a central steel rod (φ15.8mm).
- Impact Execution: The pendulum is released from a set height, simulating accidental drops or collisions.
- Post-Test Analysis: Batteries are assessed for leaks, fires, or explosions. Voltage and impedance are measured to ensure functional integrity.
Key Advantages
- Versatility: Suitable for lithium-ion, NiMH, and lead-acid batteries.
- Safety: Enclosed test chamber with fire-resistant lining and emergency vents.
- Efficiency: Automated reporting generates pass/fail results within minutes.
This machine empowers manufacturers to identify design flaws early, reducing field failures and ensuring compliance with stringent safety regulations.
