BATTEREE · INDUSTRIAL DESIGN AND ENGINEERING
Modular Battery Energy Storage
Batteree uses a stackable steel tray as its basic structural unit. The number of trays determines the system’s storage capacity.
The ongoing collaboration with Batteree continues to produce new storage variants.

Why store electricity?
The battery charges when generation exceeds demand or when demand is low (valley filling) and supplies part of the load during demand peaks (peak shaving). This helps balance the load on the grid. Depending on the connection terms, stored electricity can also be exported and sold back to the grid.
System architecture
Battery modules
Batteree uses new modules originally manufactured for electric vehicles that were never fitted to vehicles. The modules attach to the tray using their original mounting points.
Steel structure
Load-bearing trays made from laser-cut steel stack vertically. The number of installed trays determines the storage capacity.
Protection and cladding
The protective enclosure is designed with fire safety and flood risk in mind. Exterior finishes can be adapted to the installation site, from painted sheet metal to timber cladding.
Locating tabs cut into the steel
Locating tabs are cut directly into the steel crossmembers. They align the parts during assembly, eliminating a separate fitting step. Once welded, the crossmembers form the load-bearing tray.
Tray assembly
The design was refined in response to feedback from production and assembly. The Batteree team prepared the final manufacturing documentation. The tray is used in installed systems.
Storage configurations
The structure scales to the required storage capacity. The cladding and finish are selected for the installation site. The standard sheet-metal enclosure is intended for industrial use. Public and residential settings can use custom-coloured painted steel, timber cladding or an enclosure with planting and seating.
Some of the configurations shown are still in development.
Standard cabinet
Industrial configuration for production facilities and plant rooms.
Timber-clad cabinet
Tall cabinet for public spaces and building entrances.
Low-profile cabinet
Narrow industrial cabinet sized to fit within a parking bay.
Storage with integrated planter
Painted sheet metal in a colour selected for the site. An EV charger can be added.
Planter with bench
Timber cladding and optional seating for residential entrances or gardens.
Mobile storage
A lower-emission alternative to fuel-powered generators for outdoor events and hospital backup during outages.
Use concept
On-street fast charging
The planter-integrated battery recharges gradually from the street-lighting supply. It can deliver more power to the charging bollard for short periods than the supply alone can provide. This supports short charging stops and quick turnover at the bays.
Installed systems
Four outdoor Batteree cabinets are installed at an industrial site in the Zlín Region. In Votice, a system provides backup power for equipment at a food-production facility. Batteree also reports a school installation in the Central Bohemian Region, with storage integrated into planters.
Batteree at URBIS 2026
Batteree made its trade-show debut at URBIS in Brno. The exhibit included a battery storage unit with integrated planting.
