ReJoule’s mission is to maximize the value of electric vehicle (EV) batteries to reduce the amount of battery waste in our future. We enable the circular economy with our technology that offers rapid, accurate battery diagnostics. Next we will deploy systems: microgrids consisting of repurposed electric vehicle batteries powered by solar.

We offer battery diagnostics technology in a grading-as-a-service (GaaS) monthly subscription, which gives our customers access our rapid battery health diagnostic solution. The product itself comprises hardware to perform tests, algorithms and battery models to assess battery health, and a cloud-based software platform. ReJoule also deploys repurposed battery systems, where we can sell turnkey battery systems, but we can also offer design and engineering services.

One of our competitive advantages is applicability to various battery types. Our rapid diagnostic product can test any battery chemistry, and works for battery cells, modules, and even high voltage battery packs. We can also build high-accuracy battery models in less time and with less resource than competitors. We can work with 30-50 battery samples compared to thousands of battery samples required by competitors.

We're currently working with relevant stakeholders to achieve relevant certifications to make repurposed batteries deployable for stationary energy storage system applications.

Our first product grades battery modules and targets automakers and repurposing companies. A key bottleneck for these groups is how to quickly sort grade batteries to know which are usable in a second-life stationary storage system (ESS) applications. The diagnostic product can test a battery over 30x faster without compromising accuracy. The product is also portable and more easily deployable, which reduces overall cost to test, ship, and warehouse batteries.
