Higee Energy Showcases "Safety + Efficiency" Dual Strengths at SNEC

2025-07-05 | Eric

At the 18th International Solar Photovoltaic and Smart Energy Conference in 2025, Higee Energy made a grand appearance with its full-scenario energy storage system solutions, centered around the theme of "Redefining Energy Storage Value through Systems Thinking." The company showcased its 587Ah and 688Ah ultra-large capacity energy storage systems, which leverage the fourth-generation lithium iron phosphate (LFP) technology to achieve comprehensive innovation from cell to system level. These solutions provide "high-safety, long-cycle, low-cost" energy storage infrastructure for renewable energy power systems. Higee's products attracted significant attention from domestic and international clients at the exhibition.

Higee's energy storage solutions, built upon fourth-generation LFP technology, represent a complete technological revolution from cells to systems. The 587Ah and 688Ah ultra-large capacity LFP cells optimize electrode material composition and systematically apply thick electrode and gradient electrode technologies. This reduces internal resistance while increasing system energy density, enabling standard 20-foot 1500V energy storage cabinets to achieve breakthroughs of 6.25MWh (587Ah) and 6.9MWh (688Ah) capacity - a 35% energy density improvement over traditional 314Ah systems.

"The 587Ah system delivers 20-year service life for every kWh stored"

The POWER MAX system fully incorporates Higee's self-developed 587Ah cells, which benefit from parent company Baichuan's materials research to achieve 12,000 cycles. Its innovative 4×8 cluster topology design and ultra-high integration enable 6.25MWh capacity in a single 20-foot container. The pioneering 3D liquid cooling system, combined with Higee's SEA OS AI temperature control algorithm, maintains temperature differentials within 2.5°C. Multi-layer thermal barriers resistant to 1200°C, coupled with predictive temperature algorithms, effectively suppress thermal propagation.

Higee's 688Ah energy storage system utilizes standardized 20-foot 1500V cabinets to deeply integrate cell performance with system design, achieving qualitative upgrades from "single components" to "holistic solutions." Compared to traditional 314Ah systems, this solution makes revolutionary breakthroughs in three key dimensions: cycle life, space utilization, and cost control through integrated design.

Higee's exhibition appearance not only demonstrated its "systems thinking" philosophy but also injected new momentum into global energy storage development with comprehensive solutions. As new power systems advance rapidly, Higee will continue driving technological innovation to contribute China's energy storage expertise toward achieving dual-carbon goals.
