As the United States progresses towards a cleaner energy future, investigating innovative finance models that improve investment viability and affordability is critical to attaining long-term sustainability. The transition sustainable system therefore necessitates financial solutions encourage in domestic resources. purpose of this review explore can increase resources while ensuring cost for consumers. findings suggest these have potential overcome gaps, lower consumer barriers, large-scale adoption clean technologies. In conclusion, multifaceted approach integrating public, private, community-driven financing channels required expedite States. Policymakers, investors, stakeholders must collaborate models, integrate digital technologies, establish favourable regulatory conditions.

Accurate estimation of the state charge (SOC) is important for effective management and utilization lithium-ion battery packs. While advanced methods present in scientific literature commonly rely on detailed cell parameters laboratory-controlled conditions, practical engineering applications often require solutions applicable to packs with unknown or limited internal characteristics. In this context, study compares three different SOC strategies—voltage-based, coulomb counting, balance methods—implemented an independent telemetry module (TIO) their performance against a commercial system (Orion BMS2). Experimental results demonstrate that voltage-based method provides insufficient accuracy due its inherent sensitivity voltage thresholds resistance under load conditions. Conversely, periodic recalibration through full charging cycles, showed significantly improved accuracy, closely matching Orion BMS2 outputs when properly initialized. The confirm viability counting as pragmatic approach lacking data. Future research should address reducing dependency full-charge resets by incorporating adaptive techniques, such Kalman filtering observers, leveraging open-circuit measurements temperature compensation further enhance while maintaining simplicity external applicability monitoring system.
