Dukosi, A123 Systems and Nuvation Energy have released a joint design brief for an end-to-end battery energy storage system proof of concept that includes A123’s 587 Ah large-format LFP prismatic cells with Dukosi’s contactless cell monitoring system, and Nuvation’s utility-grade BMS. The reference platform is built for North American BESS project developers and system integrators seeking a pre-validated, regulatory-compliant module stack.

The PoC module uses a 1P13S configuration at 41.6 V, which is a standard building block for utility BESS rack architectures. A123’s 587 Ah cells use a proprietary US-developed LFP chemistry and are designed for long cycle life and thermal stability. Each cell carries a Dukosi DK8102 chip-on-cell monitor that communicates via the company’s C-SynQ contactless protocol to a DK8202 system hub—eliminating the wiring harness that normally runs between individual cells and the BMS. The contactless architecture is designed to reduce failure points at the cell level and to allow the monitoring layer to be retrofitted or scaled without rewiring the module.

Nuvation’s L2 BMS handles cell- and stack-level control for stacks up to 1,500 V DC. The platform is UL 1973 recognized for functional safety—a prerequisite for warranties on utility and commercial installations—and draws on Nuvation’s deployments across hundreds of commercial, industrial and utility-scale sites since 2015.
