Case Studies

ReJoule has worked with leading BESS companies to improve system performance and provide compelling  system and battery insights. Our proprietary battery testing and analysis capabilities provide a unique set of capabilities that are not available from other technology providers.  The testing technology leverages a physical, impedance based test (EIS) that captures accurate state-of-health (SOH) and critical information in 10 minutes or less.  

Here are some of the use cases that ReJoule typically supports:

    1. Provide specific actions to improve system performance by isolating the weakest modules at underperforming sites.

    2. Lead teams through capacity test processes, analysis, and definition of best practices.

    1. Leverage our 10-minute test to identify recoverable vs. non-recoverable modules

    2. Deployable test and analytics best practices at the BESS or storage warehouse

    1. Ongoing degradation modeling to support augmentation, spares planning, and financial planning.

    2. Safety & Anomaly Detection to screen for internal resistance spikes, defective welds, or severe cell imbalances that indicate pre-thermal runaway conditions.

    1. Support negotiation, warranty claims or dispute resolutions when OEM data is locked or missing.

    2. Generate independent SOH and other data through our proprietary tester, data logger, and analytics
