THUNDERCELL

UP TO 250 KWH FULLY INTEGRATED

The fully integrated THUNDERCELL 250kWh is an exceptionally capable BESS solution combining ultra‑high energy density with a 250kWh capacity with a surprisingly compact footprint.
Using a proprietary PCS (power conversion system) developed by QiOn, it is possible to charge and discharge up to 2C. It also features an advanced Multi‑voltage System (400/480/690/800/1000V).
The battery performance is maintained safe and stable by the QTMS® — QiOn Thermal Management System, that dynamically adjusts the temperature (cooling/heating/stabilizing) of the battery packs in response to the surrounding environment, allowing Polar‑to‑Desert applications.
A QiOn masterpiece.

Features

Thermal Management

All QiOn battery modules are liquid cooled and heated. The temperature control is managed using the proprietary QiOn Thermal Management System. Q‑TMS®: an active thermoregulation system designed, developed and manufactured by QiOn. (QiOn International Patent US030692).

Safety & Protection

Integrated FSS (Fire Suppression System): provides detection, extinguishing, and cool‑down capabilities (CO₂‑free for easy maintenance — no periodic replacement required). UL/CE 9540A fire test compliant. Dynamic HVB (High Voltage Box) to isolate individual racks in case of fault (one HIB per rack).

Structure & Integration

Fully integrated system: UPS, Q‑PCS, Q‑TMS, Q‑EMS, BMS, Q‑HV Box, BUX, Q‑IoT, fault/smoke/gas detection, fire extinguishing, and liquid cooling — no auxiliary cabinets required.

Entirely designed and built-to-last by QiOn.

Reliability & Control Architecture

Module‑level, self‑integrated BMS architecture , improving fault tolerance and system availability. Active energy balancing within each rack to maintain uniform SoC/SoH and reduce aging dispersion. High Voltage Box (HVB) with independent controller, enabling robust HV management and enhanced system resilience. Multi‑sensor acquisition architecture supporting advanced monitoring, diagnostics, and control via the proprietary Q‑EMS.

Plug‑and‑Use Solution

Easy to install and maintain: all utility components are fully integrated. Battery packs and power electronics are delivered pre‑installed and wired — READY TO USE. ALL‑IN‑ONE, AS IT IS.

Flexibility & Future Integration (Grid‑Oriented Applications)

Architecture designed to enable future integration of DC‑input solutions (upgrade‑ready for evolving configurations). Energy distribution and power electronics designed to support future C&I applications and operational modes. Extended Q‑EMS roadmap supporting peak shaving and advanced energy management for industrial parks, smart cities, and energy communities.

Capability to pair with co‑generation plants and operate as an auxiliary/backup power plant, including potential relocation to sites requiring temporary or additional resilience (e.g. hospitals, government buildings, critical infrastructure). IoT integration and interface readiness to support interconnection with local grid trading platforms, enabling evolution from a static asset into a VPP (Virtual Power Plant) and participation in VPPA (Virtual Power Purchase Agreement) schemes.

Warranty

  • QiOn offers a longlife warranty up to 15,000 cycles with possibility for extension.
  • In addition, QiOn offers installation, monitoring and maintenance services on request.

Featuring the Q-EMS

The Q‑EMS enables intelligent management of the entire system through remote accessible management applications, with centralized and real‑time supervision.
