Cell Benchmarking
We conduct rigorous testing to compare the performance characteristics of different cells. This includes evaluating key parameters such as energy density (Wh/L and Wh/kg), power density (W/L and W/kg), cycle life under various depth-of-discharge (DoD) and C-rates, and efficiency (charge/discharge). Our benchmarking analysis helps you identify optimal cell solutions tailored to your specific application requirements by providing comparative data across different chemistries (e.g., Li-ion, LFP, NMC, NCA, Na-ion), form factors (e.g., cylindrical, prismatic, pouch), and manufacturers.
Electrical Performance Durability Testing
We assess the long-term performance and reliability of your batteries under various cycling and environmental conditions. This involves subjecting batteries to different charge and discharge regimes, including constant current, constant power, and dynamic stress tests that simulate real-world usage profiles. We also evaluate performance degradation under varying temperatures and humidity levels. Accelerated aging tests are conducted to predict the long term state-of-health (SOH) and cycle life of your batteries, providing crucial insights into their durability.
Prototype Testing
We offer flexible testing setups to validate the performance of your new battery designs and technologies in the early stages of development. Our services Include collaborating with your engineering team to develop customized test plans that address specific performance targets and identify potential design flaws or areas for improvement before mass production. We provide detailed performance characterization and feedback to accelerate your innovation process.
BMS Characterization
We conduct in-depth testing of battery cells to generate critical data for the development and programming of your Battery Management System (BMS). Our characterization services locus on precisely mapping the cells electrochemical behavior across various operating conditions. This includes detailed analysis of voltage profiles under different charge and discharge rates, accurate determination of state-of-charge (SOC) and state-of-health (SOH) relationships, and thorough evaluation of cell impedance characteristics. The resulting data enables accurate BMS algorithms for voltage and current monitoring, temperature management, cell balancing strategies, and robust protection against over-voltage, under-voltage, over-current, and short circuits, ultimately ensuring safe and efficient battery operation within your system.
Module and Pack Performance Testing
We evaluate the integrated performance of battery modules and packs, considering the complexities of thermal management and system level behavior. This includes assessing overall capacity, voltage profiles, power delivery capabilities, and energy efficiency at the module and pack level. We utilize thermal mapping to analyze heat generation and dissipation within the system and evaluate the effectiveness of cooling or heating mechanisms. We also examine voltage and current distribution across cells within the module or pack and the communication between the BMS and individual cells or modules.
