RePower Presents Full-Lifecycle Residential Energy Storage Battery Testing Solution at the 2026 SPIR Conference
On August 28, 2026, the 2026 SPIR Residential Energy Storage Battery Ecosystem Conference and Global Residential Energy Storage Battery TOP Ranking Release, themed Innovation-Led Growth and Supply-Demand Restructuring, was held in Bao'an, Shenzhen. Shenzhen RePower Technology Co., Ltd. (RePower) attended the event by invitation. R&D Director Li Haipeng delivered a keynote titled Full-Lifecycle Testing Solutions for Residential Energy Storage Batteries, presenting RePower's technical expertise and full-stack capabilities in residential battery testing.
Rapid Industry Growth Brings New Testing Challenges
In 2026, the global residential energy storage industry entered a period of accelerated growth. According to SPIR data, global residential energy storage battery shipments reached 61GWh in the first half of 2026, up 206% year on year, and full-year shipments are expected to exceed 135GWh. As the market expands, testing challenges are becoming more pronounced. Standard laboratory cycling differs significantly from the shallow charge/discharge profiles found in real households, contributing to overstated lifetime claims. Cell inconsistency also increases over time, causing module voltage spread to drift and raising the risk of premature failure. Meanwhile, current certification testing focuses mainly on safety compliance and lacks full-lifecycle validation under real operating conditions. Companies therefore need a complete closed-loop testing framework from R&D through retirement.
Full-Chain Coverage: A Complete Test Matrix from Cells to Systems
To address these challenges, RePower launched a full-lifecycle testing solution for residential energy storage batteries. The solution spans R&D and design, manufacturing, system integration, project construction, and operations and maintenance, helping improve product reliability, consistency, and service life.
For cell testing, RePower's 5V and 6V cell test systems support intelligent multi-range switching, deliver accuracy up to 0.02% F.S., and provide a 3ms high-speed dynamic response. They cover the electrical performance, operating-profile simulation, and pulse testing requirements of energy storage cells.
At the module and PACK level, RePower's 60V~500V module/PACK test systems use three-level topology and achieve energy regeneration efficiency of up to 93%, supporting performance testing for a wide range of residential storage modules and battery packs. Complementary PCBA, EOL, and GGC test systems cover battery protection board verification, module/PACK safety and end-of-line testing, and functional testing of finished and semi-finished products, creating a complete quality control loop from components to complete systems.
For aftermarket O&M, RePower offers portable cell charge/discharge maintenance units, portable battery module charge/discharge maintenance units, and portable energy storage system safety test equipment. These lightweight, easy-to-use products address on-site testing during installation and aftermarket service. The portable cell maintenance unit supports constant-current/constant-voltage charging and discharging, capacity calibration, and balancing maintenance for cell replacement, performance testing, and second-life regrouping. The portable battery module maintenance unit supports wide-voltage-range charge/discharge testing and BMS communication testing. The portable energy storage system safety test unit has a built-in power supply and compact form factor, making it suitable for inspection and maintenance at user-side energy storage stations, residential and mobile storage battery packs, warehouse sampling, and return-to-factory repair. Together, the three products provide a portable testing portfolio spanning cells to systems and installation to retirement.
At the software level, RePower test systems use a proprietary intelligent control platform with AI-powered data analysis. The software supports custom data-point calculations, rapid historical data retrieval, and multidimensional comparative analysis, helping customers locate issues efficiently and improve both testing productivity and decision quality.
