2nd Hand EV Battery SOH Estimation and 2nd Life Application

We provide state-of-art SOH estimation service and 2nd hand electric vehicle battery second life application as Battery Energy Storage System (BESS).

01 Our Mission

We are dedicated to developing cutting-edge technologies that convert used electric vehicle batteries into Battery based Energy Storage System (BESS).

Research & Technology

01 Whole-Pack SOH Estimation Technology

Comparing to traditional battery health diagnosis, our fast pulse reactive whole-pack SOH diagnosis estimates the whole pack SOH within 10 seconds and consume less than 1kWh of electricity.

02 Hierarchical BMS and EMS Structure

An hierarchical BMS and EMS structure is designed to control all packs in the system. By monitoring the energy consumption and battery health, we manage to protect your BESS from any possible accidents and maximize durability of the system.

03 Battery Hospital, Battery Bank

With our edge technologies, batteries can be diagnosed and valuated via our system and a battery health report can be delivered. Our online energy storage network allows users to conduct capacity rental service.

03 Who We Serve

01 Automotive Manufacturers (OEMs)

Automakers can use Sifra Energy’s battery diagnostic technology to rapidly evaluate returned or retired EV battery packs. Our testing platform enables classification, residual value assessment, and optimal routing of batteries toward reuse, recycling, or warranty management.

02 Energy Storage Operators & Integrators

Our health monitoring and grading algorithms allow energy storage operators to monitor battery pack condition in real time, detect weak modules, and reduce maintenance costs. The technology supports predictive maintenance and improves reliability of second-life battery energy storage systems (BESS).

03 Commercial & Industrial Energy Users

Businesses equipped with solar generation can deploy Sifra Energy storage systems to store excess renewable electricity, reduce peak demand charges, and increase energy independence. Our solutions enable cost-effective on-site energy storage using validated second-life EV batteries.

04 Investors & Financial Institutions

By quantifying battery health and remaining useful life, Sifra Energy provides a technical basis for valuation of energy storage assets. Our diagnostics transform batteries from uncertain liabilities into measurable infrastructure assets, enabling financing, insurance assessment, and secondary market transactions.
