THUNDERGRID

5 MWH - DISTRIBUTED LAYOUT

Robust, reliable, powerful.
The THUNDERGRID (5MWh per 6m/20ft container) achieves a storage capacity up to 10MWh per PCS. Polar‑to‑Desert certified.
The THUNDERGRID is QiOn's most powerful high‑density, long‑lasting, Battery Energy Storage System. The ideal solution for the largest energy fields.
It is composed of:
  • a 6m/20ft BESS encased in a high strength proprietary container‑type structure packed with QiOn's advanced battery technology with a power supply capacity of 5MWh, weighing less than 45t.
  • a Conversion Cabinet that contains high efficiency PCS and Transforming System.
  • a Dispatch Panel which functions as a switch for all the electrical lines and a controller for the system's communication.
It can be connected to high voltage (HV) and even extreme high voltage (EHV) power systems, allowing it to be deployed for grid‑scale applications. Multiple units can be linked together with ease.

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®: our patented active thermal regulation system derived from motorsport experience.

Smart Energy Management

Scheduling capability for BESS charge/discharge sessions.

Safety & Protection

Integrated FES (Fire Extinguishing 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 HVB per rack).

Entirely designed and built-to-last by QiOn.

Reliability & Control Architecture

Module‑level, self‑integrated BMS architecture (no master/slave logic), 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 fully integrated: all utility components are fully integrated with four‑side access doors for easy inspection of battery racks. Battery packs and power electronics are delivered pre‑installed and wired — ready to use.

Flexibility & Future Integration (Grid-Oriented Applications)

Architecture designed to enable future integration of DC‑coupling 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.
