We are Universe Energy, and we are the battery dismantling and repurposing company.

Our mission is to scale battery reuse as the largest source of the next billion batteries. The world needs 2 billion batteries by 2050, but this comes at a huge cost to the planet, as we need to mine 30x more. We dismantle and sort used battery packs 7x faster and 50% cheaper than by hand using robotics, AI and sound for EV OEMs, battery makers and fleets. Once we dismantle 1000s of battery packs, we repurpose them into $4000 cheap grid batteries that are 20% cheaper than making new ones. Our vision is to become the leading maker of zero-impact batteries by building 1 million batteries/year by 2035. This will power a truly clean energy revolution at scale and reduce 6 Giga tons of CO2 by 2050. We are Universe Energy, and we make batteries eternal.

Job objective Before Bonobo disassembles the battery from pack to module, State-of-Health data is measured to determine the age, state, and value of the modules and cells in the battery pack. The data informs the best next step for its life: remanufacturing, repurposing, or recycling. Then the battery packs are discharged from residual power to prevent any danger. The battery packs are disassembled up to the module level based on the battery's configuration. You will design the best sequences to disassemble them from pack to module level and beyond for high-volume EV battery packs. You will develop testing methods to obtain State of Health, battery value, and lifetime prediction through electrical and non-intrusive pathways. You will design electrical systems to discharge modules in parallell while you will operationalize the batttery testing infrastructure at the pilot facility with vendors and partners.

How you will contribute

• Map disassembly sequences of high-volume EV batteries from pack up to the module level. Track decompositions of modules, materials, and cost breakdown of high-volume battery packs and store them in a database.
• Track state-of-the-art battery architectures, cell chemistries, and form factors to update testing, discharge, and disassembly methods, like LFP cell developments and cell-to-pack architectures.
• Design electrical diagnostics methods for State of Health data. Select develop hardware and software with vendors.
• Make software to measure, store and analyze SOH data from the BMS outputs through the CAN-bus. Model battery value, State of health, and lifecycle degradation predictions.
• Research non-intrusive testing methods to measure and assess State-of-Health through ultra-sonic, X-ray, and CT-based methods.
• Develop electrical discharging systems to remove current from battery modules that are configured in parallel.
• Run performance and lifetime testing for warranty and insurance requirements, manage the bill of materials of testing infrastructure and coorindate with vendors.
• Perform system design reviews, trade-studies decisions, and lead make-buy decisions for the battery hardware & software technology stack.
