Quality Assurance

Quality and safety are the main requirements of NiMH hybrid battery packs. To ensure basic requirements, many factors must be considered from a quality assurance perspective when developing and manufacturing NiMH hybrid battery packs. Okacc Hybrid Batteries has very strict quality and environmental control systems. In the past several years, we have passed the ISO9001: 2015 certification and the ISO14001: 2015. Okacc Hybrid Batteries guarantees a three-year limited warranty against quality and materials defects.

Okacc Hybrid Batteries starts by purchasing high-quality raw materials and then assembling these materials on a production line using automated equipment, along with the latest in manufacturing processes and a high degree of precision quality control to ensure our battery quality. For instance, our NiMH hybrid battery processing, manufacturing, and inspection equipment are directly imported from professional equipment manufacturers in Taiwan. Other materials, like separators, are imported from qualified suppliers in Japan and China. We then use laser equipment to detect the thickness in the coating process. This laser equipment communicates with the coating machine in a feedback system to maintain tight tolerances and ensure no cells are produced outside preset limits. Okacc Hybrid Batteries also deployed a PDMS (Product Data Management System) for quality control. Every step in the manufacturing process is checked, logged, and judged so that if a problem occurs, it will be discovered early, and any faulty product will be discarded. This automated attention to every step of the manufacturing process results in higher yields and, ultimately, lower production costs.

Okacc Hybrid Batteries updated the operation equipment and working flow with a new water-based manufacturing method. With less labor cost and less equipment required, manufacturing has now become more effective. All advantages bring a higher qualified passing rate of products and excellent quality. Besides, the electrochemical performance is much better than before with water-based manufacturing. This talented technology became one of our core competencies.

The Battery separator is coated with a hydrophobic coating, and well-shaped surfaces offer a better environment for NiMH transformation. Metal doping also significantly improves electronic conductivity. Thus, our power NiMH battery, like some pouch cells, could deliver a sizeable continuous discharge current at an enhanced safety level. We could also apply better thermal conductivity for pouch cells, improving battery performance and long cycle life.

Also, from slurry manufacturing to unit cell manufacturing with fully automated production equipment to ensure stability and consistency of battery quality. The water-based manufacturing, thermal conductive design, cell assembly, separators, and electrolyte aspects have been well organized, and the battery got superior safety. Okacc Hybrid Batteries has excellent thermal stability tests (and operation over a more comprehensive temperature range) and overall protection under stress conditions like over-charge, short-circuit, acupuncture, burning, etc. Okacc Hybrid Batteries NiMH hybrid is the most reliable car battery for customer applications.

Developing, designing, testing, producing, and delivering a high-quality NiMH hybrid battery pack requires a commitment to and embracing of quality assurance. Okacc Hybrid Batteries can develop exceptional, safe, and environmentally friendly products by following the guidelines above.
