BSLBATT, a leading lithium battery manufacturer based in Guangdong, China, announced today that its B-LFP48-100E LiFePO4 battery has successfully passed rigorous testing by TÜV, one of the world’s top three certification bodies, and obtained IEC 62619 certification. Designed for the rapidly growing solar-plus-storage industry, these high-safety LiFePO4 batteries demonstrate BSLBATT’s commitment to meeting international standards for safety, reliability, and quality. This achievement reinforces BSLBATT’s position as a trusted provider of energy storage solutions in global markets.
What is IEC 62619 and what is its meaning?
IEC 62619 is an international safety standard for industrial lithium batteries, covering electrical, mechanical, thermal, and functional safety requirements. It applies to stationary (ESS, UPS) and motive (AGVs, forklifts) applications, excluding EVs. Key tests include overcharge, short circuit, thermal runaway, and BMS validation. The 2022 update added EMC, laser-triggered propagation tests, and stricter BMS software checks.
Understanding IEC 62619’s technical requirements naturally leads to appreciating its real-world value. This certification isn’t just paperwork – it’s proof that a battery can handle real-world stresses while keeping users safe:
- Safety Assurance – Validates protection against thermal runaway, fire, and electrical hazards through rigorous testing
- Market Access – Serves as maa ndatory requirement for entering key markets like EU and Australia
- Quality Benchmark – Demonstrates compliance with international standards for reliability and performance
- Competitive Edge – Differentiates products in an increasingly crowded energy storage market
- Customer Confidence – Provides end-users with verified safety and quality guarantees
What are the features of this 5kwh battery?
The B-LFP48-100E is a 48v (51.2V), 5kwh capacity rackmount battery that can be paralleled with up to 63 modules of the same capacity, allowing for a capacity expansion of approximately 300kwh, and is designed for applications where space is limited or where multiple batteries need to be seamlessly integrated into a single system, redefining energy storage solutions to meet a variety of needs, and is widely used in home energy storage systems and energy storage systems.
- Modular Design
