Hear what people are saying about our tech.
“A battery diagnostic technology that is fast, non-invasive, and capable of handling packs of up to 800V would be invaluable in the envisioned marketplace. The impedance data from ReJoule's system would be game-changing for the EV industry, wherein battery diagnostics and health data in the field is lacking.”
— VP at Top 10 Automaker
“I am impressed with what the team has achieved. The concept is innovative! Their ability to perform battery diagnostics is incredibly valuable… We love how enthusiastic the team is and look forward to seeing what they can do.”
— GM at Top 5 Battery Producer
“ReJoule’s tool helps us to remanufacture our EV batteries for in-vehicle usage…it helps us to really understand if the core received is a worthy product for our customer and evaluate the quality of the core.”
