ReJoule’s fast battery diagnostics enables a more accurate measurement of the battery's health. Uncertainty on battery health adds overhead costs which leads to excess waste along the battery’s life cycle. As batteries power more of our cars and buildings, more advanced diagnostics helps bring battery costs down and accelerate electrification. Our proactive system dynamically adjusts for optimal performance to increase usable battery capacity and improve safety. By enabling a step-change in the world’s understanding of how batteries perform, we can make battery systems cheaper, safer, and more sustainable.
