2023

Aug 2023 : Spark of an Idea Noticed the gap between growing residential energy costs/blackouts and rising volumes of end-of-life EV batteries. Revoltamp’s thesis formed: repurpose EV packs into affordable, modular home ESS.

Oct – Dec 2023 : Early Discovery & Feasibility

• Mapped the residential ESS landscape (Powerwall/Enphase) and second-life battery ecosystem.

• Defined first architecture: 48 V modular stack with split-phase inverter and BMS balancing strategy.

• Drafted initial UL compliance path (UL 9540/1741/1973) and certification dependencies.
