株式会社日本蓄電池 Product Lineup

PLB's lithium battery products have the following excellent features: - Wide operating temperature: Capable of withstanding harsh environments from -40°C to 60°C Covers a wide operating temperature range from freezing cold regions to hot and humid environments, maintaining stable output. - Excellent low-temperature characteristics: Discharge at -40°C and charging from -20°C Supports discharge down to -40°C, even in low-temperature environments where typical lithium-ion batteries struggle. Additionally, it is designed for cold regions, supporting 0.5C charging between -20°C and -10°C. - 5C ultra-fast charging: Achieves operational recovery in the shortest time Supports extremely high-rate fast charging at 5C, boasting a charging efficiency of over 94%. It is ideal for applications such as logistics robots (AGV/AMR) and electric mobility, where minimizing downtime is crucial. - Efficient energy management: Low-loss design with over 94% charging efficiency Maintains high energy efficiency even during fast charging, enabling efficient operation while minimizing heat generation.

PLB's battery packs are based on high-performance LFP (lithium iron phosphate) cells produced in-house and are equipped with an advanced BMS (Battery Management System). They create an optimal power environment for sites where reliability is essential, ranging from industrial equipment to energy storage systems. 【Product Features】 - High reliability through integrated production: Complete in-house process from cell to pack assembly All processes, including raw material processing, cell manufacturing, BMS development, and pack assembly, are completed in-house at PLB. Data from each process is linked, ensuring high-quality traceability. - Advanced BMS: Balancing safety and longevity In addition to overcharge, over-discharge, and overcurrent protection, the system includes a cell balancing function that optimizes voltage balance between cells. This maximizes the performance of the cells and contributes to the longevity of the system. - Excellent environmental resistance: Stable operation under harsh temperature conditions Utilizing the characteristics of the internal cells and considering heat dissipation in the enclosure design, the product is suitable for outdoor installation and use in harsh industrial environments.
