Innovation, quality and safety have always been foundational factors in the design and manufacture of maxwell+spark’s LiFePo4 batteries. With the groundbreaking attainment of UL 2580 listing, maxwell+spark’s commitment to safety and design excellence remains unrivalled. This milestone solidifies maxwell+spark’s position as a leader in the motive industry.
UL 2580 is the premier standard for ensuring the safety of Lithium-Ion batteries, specifically for the motive industry. This prestigious certification will now apply to maxwell+spark’s forklift batteries classified with the following specifications: 36V 450Ah, 36V 560Ah, 36V 750Ah, 36V 840Ah, 48V 450Ah, 48V 560Ah, 48V 750Ah and 48V 840Ah.
The UL listing for Maxwell+spark batteries signifies that they have successfully passed a series of rigorous mechanical, electrical, environmental, tolerance and quality tests. These comprehensive assessments included:
Mechanical Testing:
- Rotation (simulating an overturned vehicle,)
- Vibration endurance (simulating lifetime vibration exposure)
- Shock resistance (evaluating mechanical shock tolerance)
- Drop testing (simulating accidently being dropped during installation)
- Crush resistance (assessing the battery’s ability to withstand crushing during accidents)
Electrical Testing:
- Temperature testing (determining the battery’s ambient temperature rating)
- Overcharge protection (ensuring the battery safeguards against overcharging)
- Over-discharge protection (ensuring the battery safeguards against over-discharging)
- Imbalanced charge protection (verifying protection against overcharging with imbalanced modules)
- Short circuit resistance (ensuring safety under short-circuit conditions)
Environmental Testing:
- Thermal cycling (evaluating the battery’s ability to withstand changing environments, including extreme conditions such as +85°C/185⁰F)
Tolerance to Cell Failure:
- Single cell failure test (assessing the battery’s response to a single cell failure within a full battery assembly)
Remarkably, the samples used for these tests not only passed with flying colours, but many of them remained in perfect condition following the rigorous testing. Even when intentionally damaged through nail penetration to simulate single cell failure, the thermal events initiated within a cell did not propagate to any other cells in the assembly, demonstrating exceptional safety and durability.
Fathima Moosa, lead mechanical engineer in charge of certification, expressed, “The certification process cannot be reduced to lab testing alone – this was merely the culmination of thousands of hours of effort by several employees across all levels in the organization, all fiercely committed to the safety and performance of our products.”
This significant UL 2580 certification validates the performance, reliability, and safety of maxwell+spark’s batteries. The company remains dedicated to pushing the boundaries of battery technology to provide customers with the highest quality and safest products in the industry.
