With over 15 years of dedicated experience in battery testing, Acculon boasts a world-class battery test lab that serves as the nucleus for innovation in our battery module and pack development. Our extensive knowledge and lessons learned over the years have been channeled into a comprehensive product development program, ensuring that every aspect of our batteries meets the highest standards of quality and performance.

We’re extremely proud of the success of our battery laboratory, and in its years of operation, we have supported major battery and automotive OEMs in battery cell, module and pack calendar and cycle life validation, high-accuracy battery model development, battery warranty analysis, cell FMEA, and application/vocational battery cell selection. Between our experience in pack validation and vehicle program cell characterization, there’s a strong likelihood that you’ve encountered cars on the road that have directly benefited from our top-tier facility.

Acculon’s battery test lab is equipped with state-of-the-art testing capabilities, boasting over 110 channels for cell testing, capable of handling charge and discharge rates of up to 400 A at voltages of up to 8 V, enabling the simulation of real-world conditions with precision and accuracy.

Temperature control is a critical factor in battery performance, and Acculon ensures precise control through the use of environmental chambers and Peltier thermal controllers. This meticulous attention to detail allows them to replicate a wide range of temperature conditions, providing valuable insights into battery behavior under varying thermal stresses.

Acculon’s module and pack testing capabilities are equally extensive, with up to 8 channels dedicated to system-level testing. Each channel can handle charge and discharge rates of up to 125 kW, and up to 420 V, ensuring that every aspect of the battery pack is thoroughly evaluated for performance, safety, and reliability.

Every test is meticulously run by proprietary software developed and maintained in-house by Acculon’s team of laboratory engineers. The independent data acquisition system, with NIST traceable calibrations, ensures the highest level of accuracy and reliability in all results and evaluations.

Our battery laboratory is not just a testing facility; it’s a hub of battery design and development innovation and problem-solving, as well as ongoing research and development in different cell chemistries, including sodium-ion batteries (SiB). In fact, it is not an understatement to say that we are SiB experts.
