Electric machines need power – but there isn't a grid connection everywhere they work. On the construction site, at the port, on the handling yard, it's often too weak, too far away, or simply not there.
Our Battery Energy Storage Systems close that gap. They store energy and give it back as fast charging – for machines, commercial vehicles and whole fleets. Mobile or stationary, from a compact unit to a high-power container system that can be trucked to the site. Scalable, so the system fits your needs rather than the other way round.
What our BESS solutions deliver:
- Off-grid fast charging of electrified off-highway machines and commercial vehicles
- Peak load reduction that takes the strain off existing grid connections
- Flexible power supply for construction sites, logistics hubs, municipal and intralogistics applications
- Emission-free energy – the alternative to the diesel generator
Applications and use cases
Construction sites and off-highway use
• Fast charging of construction machinery and equipment
• Temporary power supply with no fixed grid connection
Public and commercial charging infrastructure
• Supporting existing charge points at times of high demand
• Bridging weak grid connections through buffer storage
Logistics, ports and industrial sites
• Powering fleets and handling yards
• Load management to avoid grid peaks
Test tracks and demonstrations
• Powering municipal equipment and sharing fleets
• Charging infrastructure where grid capacity is limited
DEUTZ Powertree
Mobile high-power charging, ready anywhere
Where there's no charging infrastructure, the DEUTZ PowerTree brings it along. A mobile Battery Energy Storage System with built-in fast charging: transport it to the site, set it up, charge. If needed, it can also be connected to the grid to extend running time.
Charging runs over the CCS2 standard, the common connector for DC fast charging of electric vehicles. So the PowerTree charges DEUTZ drive systems as readily as other electric vehicles and machines – bridging missing infrastructure, cutting idle time and keeping your fleet at work.
Two storage sizes:
The PowerTree comes with 126 kWh or 252 kWh of usable storage capacity – the smaller unit for flexible standalone use, the larger for longer running times or several charging cycles without a top-up. The 252 kWh version carries double the battery capacity and is correspondingly heavier.
KEY FACTS AT A GLANCE

| AC output | 32 A at 400 V plus 16 A at 230 V, via CEE connector |
| AC input (grid top-up) | 63 A at 400 V, software-limitable to 32 / 16 / 6 A |
| Nominal voltage | 352 V |
| Operating temperature | –30 °C to +50 °C |
| Protection rating | IP65 – sealed against dust and water jets |
| Safety | active battery cooling and fire detection built in |
| Service life | designed for 10 years, around 2,500 full charge cycles |
| Dimensions and weight | 3,000 × 2,500 × 2,600 mm, under 5,000 kg – truck-transportable |
Your benefits:
- Charging without the grid: fast charging right on site, 100 % even with no grid connection.
- Plug & play: set up, connect, charge straight away – no installation.
- Mobile: energy that moves with the site instead of being tied to it.
- Ruggedly built: high-grade industrial components for reliable continuous off-highway use, from –30 °C to +50 °C.
- Emission-free: for construction and industry with no exhaust at the point of use.
- Peak shaving: clips grid peaks and smooths the power supply.
Beyond the PowerTree: our next generation of mobile charging solutions
The PowerTree is the beginning. We're developing our mobile charging solutions towards heavier-duty variants – with storage capacities up to 1 MWh for now. Powerful and still transportable, out to where the work happens. The new product line will have a name of its own; we'll introduce it shortly.

PODCAST INSIGHT
Electrified construction sites with the PowerTree
"Construction sites & excavators soon to be electric?" - Our experts Thomas Adermann and Christian Pelger tackled this question in the Charged Podcast and take us on a fascinating journey to the construction site of the future. The focus is on the key challenges of converting to an emission-free construction site:
- How do we deal with the limited battery life of power-intensive machines?
- How can construction site operators minimize longer delays in work due to charging times?
- What options are there to enable fast charging on construction sites if there is no charging infrastructure?
