Solution
Discarded e-vehicle batteries become energy sources - economical, sustainable, forward-looking.
E-fleet operators are currently at a pivotal point: having invested heavily in electromobility, they now need to ensure the long-term sustainability and profitability of this investment. They require sustainable, economical and strategic solutions to secure this investment.

With the Battery Hotel, STABL Energy offers e-fleet operators a smart, sustainable solution for the economically viable reuse of used vehicle batteries from their own e-fleet. After collection, testing and processing, the batteries are converted into modular, stationary storage systems and installed directly on site by the e-fleet operators – for example in the depot or charging hub.
This allows you to reduce your energy costs by reducing peak loads (peak shaving), increase the self-consumption of your PV system and reduce grid connection fees through intelligent load management. In addition, the backup function provides security in the event of power outages.
More control, more sustainability and measurable cost benefits, without premature disposal of decommissioned batteries.
Challenges for e-fleet operators
The electrification of transportation and thus also of fleets is considered a milestone in the transportation revolution. In practice, however, fleet operators today face a number of complex challenges that go far beyond the mere purchase of electric vehicles.
Expensive battery investments with a limited life span
Expensive batteries quickly lose value in the vehicle - despite having residual capacity. This is economically problematic.
No concept for batteries at the end of life
Operators are left with functional old batteries - take-back and disposal costs, no second use.
High energy costs due to peak loads
Central charging hubs drive up electricity costs - without storage, peak loads can hardly be controlled.
Lack of a circulation strategy
Own batteries could be reused - but there is a lack of technology, partners and concept.
Grid limits & lack of storage strategies
Increasing charging requirements meet insufficient grid connections - without smart storage, expensive stand-alone solutions are the result.
Ecology needs profitability
Sustainability alone is not enough - only solutions with a real ROI are viable in the long term.
How it works
Just imagine: The battery that powered an e-bus yesterday will supply your company premises with electricity tomorrow, buffer peak loads or help you make the most of low electricity prices. STABL is already successfully implementing precisely these applications for its customers.
Get more from your battery investment
Decommissioned e-vehicle batteries remain technically usable for other applications. STABL reconditions them efficiently, safely and sustainably for stationary use, thus extending their service life, increasing the ROI and exploiting the full potential of your original fleet investment.
Rethinking the circular economy - independent and sustainable
Recycling is good - reuse is better: STABL uses intelligent processing to extend the service life of your vehicle batteries by up to 67% and turns them into powerful stationary storage units. This creates a genuine circular economy: independent, resource-saving, measurably sustainable.
Creating energy independence & grid benefits
Electrification of the fleet is only the first step: the next stage is decentralized energy self-sufficiency. Your decommissioned vehicle batteries become a central component of your own energy system through reprocessing.
Turnkey storage solution
Individual planning, plug & play integration and remote maintenance guarantee full transparency and maximum uptime for your storage system.
Mastering regulation and ESG requirements
You meet key legal requirements for the take-back and reuse of vehicle batteries without the need for complex in-house solutions. You make a demonstrable contribution to your ESG goals, for example in the area of circular economy and CO₂ reduction - a win-win situation both economically and ecologically.
Rely on modular multilevel inverter technology now
STABL technology really comes into its own in the battery hotel approach. This is precisely where the reuse of used vehicle batteries shows what makes our technology unique, because STABL transforms used vehicle batteries into safe, powerful and economically viable energy storage systems.
Second-life batteries are different - STABL enables safe operation without time-consuming sorting in advance. Different battery types can be used within a battery storage system. Each module is individually monitored and controlled for maximum efficiency and robustness.
36-fold redundancy per container. Zero downtime. Even in the event of multiple failures, STABL keeps operations running without interruption. This makes us the first choice for applications where downtime is not an option.
Low integration costs, modular scaling and a flexible setup that adapts to any battery - this is what makes our Battery Hotel projects possible in the first place.
Together with the largest Scandinavian public transport and e-bus fleet operator Nobina AB, STABL has successfully implemented the Battery Hotel concept: E-bus batteries from the company's own e-bus fleet are tested after vehicle use, processed and reused as stationary battery storage units at Nobina's locations. The storage solutions are used for load management and grid support, among other things - with measurable economic and ecological added value.
