Sifra Energy offers a rapid whole‑pack state‑of‑health (SOH) estimation service for used electric‑vehicle batteries, delivering diagnostic results in under 10 seconds while using less than 1 kWh of electricity. The company then integrates these pre‑qualified packs into Battery Energy Storage Systems (BESS) managed by a hierarchical BMS/EMS that continuously monitors health, controls energy flow, and ensures safety, providing grid operators and commercial users with reliable, cost‑effective second‑life storage solutions.

Problem
Used electric‑vehicle (EV) battery packs have uncertain remaining capacity and safety status, making it difficult for grid operators and commercial users to repurpose them as reliable energy storage assets. Traditional health diagnostics are slow, energy‑intensive, and often require disassembly, limiting the economic viability of second‑life applications.
Solution
Sifra Energy provides a rapid whole‑pack state‑of‑health (SOH) estimation service that delivers diagnostic results in under 10 seconds while consuming less than 1 kWh of electricity. The fast pulse‑reactive measurement is performed on intact battery packs, producing a detailed health report that enables accurate valuation for second‑life use. Based on the SOH data, Sifra integrates the packs into Battery Energy Storage Systems (BESS) managed by a hierarchical Battery Management System (BMS) and Energy Management System (EMS). This architecture continuously monitors health, controls energy flow, and implements safety safeguards across multiple packs, extending system lifespan and ensuring reliable grid or commercial operation.
Target Audience
Primary customers are grid operators, commercial energy users, and renewable‑energy developers seeking cost‑effective, pre‑qualified battery storage solutions for peak‑shaving, load‑shifting, or backup power applications.
