Modern chip manufacturing, CNC precision machining and core data‑center computer rooms impose extremely stringent requirements on power‑supply quality. Even grid instantaneous voltage drop or short‑time power outage lasting only several seconds can lead to wafer scrapping, machine‑tool spindle damage and server shutdown, resulting in economic losses of hundreds of thousands at every turn. Tianjin Plannano Nano‑Technology Co., Ltd. has independently developed the Plannano supercapacitor energy‑storage system. Featuring a standardized high‑power solution of 1800 kW / 10 s and paired with the INPAVC dynamic voltage restorer, it delivers millisecond‑level energy‑replenishment response and serves as a core guarantee for short‑time uninterrupted power supply in precision‑industry scenarios.
The core of the whole system adopts high‑capacity 3.0 V / 3000 F supercapacitor cells, namely high‑performance capacitor units. A single cell achieves up to one‑million‑cycle service life and stable operation across a wide temperature range of ‑40 ℃ to 65 ℃. With low internal resistance and outstanding instantaneous discharge capability, its maximum short‑circuit current reaches 12.5 kA, enabling instant full‑load power output of 1800 kW. Different from lithium‑based batteries such as lithium‑titanate‑oxide (LTO) batteries and LFP batteries, supercapacitors excel at ultra‑fast power support and offer irreplaceable advantages for voltage‑sag and short‑term power‑loss conditions. They can be deployed as standalone complete sets or combined with various batteries to build hybrid energy‑storage units.
The Plannano 1800 kW / 10 s supercapacitor energy‑storage system adopts hierarchical modular design: 3P16S forms a 48 V standard sub‑rack; eighteen sub‑racks are connected in series to build an 864 V supercapacitor string; four strings are paralleled to constitute the complete energy‑storage system. It is equipped with a dedicated busbar cabinet and three‑level CMS intelligent management system, which monitors voltage and temperature in real‑time at cell, module, string and whole‑unit levels and implements balanced control to avoid single‑point failures. The cabinet adopts natural air‑cooling heat dissipation with IP20 protection grade. Compact and neat cabinet layout allows installation in factory power‑distribution rooms without dedicated constant‑temperature computer rooms.
The matched dynamic voltage restorer achieves a response speed ≤ 1 ms. Once grid voltage drop down to 0 V is detected, faulty mains power will be isolated immediately. The supercapacitor energy‑storage unit continuously outputs standard 0.4 kV three‑phase four‑wire electric power to provide 10‑second reliable backup power, sufficient for precision‑equipment shutdown protection, data saving and production‑procedure completion. The unit can mitigate voltage fluctuations within the full range of 0‑130 %. The voltage distortion rate under full‑load operation stays below 2.5 %, and voltage unbalance is controlled within 4 % under unbalanced‑load conditions, effectively solving factory‑grid flicker and harmonic interference issues.
The system is equipped with multi‑layer safety protections, providing real‑time early‑warning for over‑voltage, over‑current, short‑circuit, high‑temperature and fan faults. A built‑in automatic bypass circuit switches the load back to mains power automatically during equipment maintenance or internal faults so that production will not be interrupted. It supports multiple communication protocols including RS485, Ethernet and CAN. A 10‑inch touch screen enables local visual operation; operating waveforms, fault logs and charge‑discharge data can be exported via USB flash drive for convenient operation‑and‑maintenance traceability.
The Plannano supercapacitor energy‑storage system by Tianjin Plannano Nano‑Technology Co., Ltd. has been applied in overseas high‑power projects. Designed in full compliance with national energy‑storage standards NB/T, GB and DL/T, it is suitable for high‑value loads such as chip fabs, CNC workshops and data centers. If longer backup duration is required, it can be freely combined with LTO batteries and LFP batteries to form hybrid energy‑storage units, meeting both instantaneous voltage‑stabilization and long‑term backup‑power requirements. Robust supercapacitor technology safeguards the bottom‑line power consumption for enterprise production.
