The science behind our technology speeds up test time from 6 hours to 10 minutes

  • Proven techniques.

    We utilize established characterization techniques to quickly and accurately grade batteries. These techniques are called electrochemical impedance spectroscopy (EIS) and hybrid pulse power characterization (HPPC).

  • Rapid insights.

    We perform an EIS test across three decades ranging from 1 Hz down to 0.1 Hz to enable rapid insights into materials degradation such as SEI layer growth, increased charge transfer resistance, and increased diffusion resistance.

  • Fast and non-invasive.

    EIS is a fast, non-invasive, and reliable diagnostic to grade battery modules and speed up UL1974 test time from 6 hours to 10 minutes. Plus, our modern software toolset helps keep track of battery parameters.

How ReJoule’s technology works

  • For batteries already removed from vehicles, attach our BattScan to your batteries’ terminals. Otherwise, plug our BattScan directly into your vehicle’s DC Fast Charging port!

  • ReJoule’s tools will accurately measure your battery’s State of Health in minutes (custom products can be as fast as 30 seconds) – significantly faster than today’s standards

  • Our tool will provide a Battery Health Report detailing all our diagnostics and grading. Use the State of Health data to decide how you will maximize the useful life of your used EV batteries!

 FAQs

 

  • We are at the beginning of the electric mobility revolution. From scooters and e-bikes to cars and airplanes, all-electric is the future. Powering all those machines requires more batteries than ever before, and as those batteries age, they need to be constantly maintained – and replaced.

    However, those “old” batteries still hold a lot of value. As we simultaneously sprint towards using more clean energy, used batteries are critical for stationary storage, which impacts renewable energy availability, consumption, and overall equity. The used electric vehicle (EV) batteries of today will power (pun intended) the energy grid of tomorrow.

  • ReJoule combines hardware, software, and machine learning algorithms to provide accurate measure batteries’ State of Health (SOH) faster than any other existing tool. Our technology is non-invasive and is designed for flexibility; it can work with any chemistry, form factor, and voltage.

  • Unlike a traditional BMS, which becomes more unreliable as a battery ages, ReJoule’s technology utilizes a battery’s actual aging and usage patterns to tailor our State of Health measurements.

  • We are proud to have received grant funding from the National Science Foundation, California Energy Commission, and U.S. Department of Energy. We are also part of accelerator programs such as LACI’s Energy Innovators, Plug & Play, and the Southern California Energy Innovation Network.

  • Please contact us at info@rejouleenergy.com. We are always evaluating new projects and opportunities to partner with other companies passionate about EV batteries’ role in the circular economy.
