Reduce the noise level of your fleet for night operations by converting to electric: A guide
Are nighttime disturbances caused by your diesel fleet a business risk that can cost you up to 5,000 euros per incident? Switching to quiet electric drives solves this problem and saves your budget. Discover the pragmatic way to electrification.
The topic briefly and concisely
Reduce the noise level of your fleet for night operations by converting to electric and avoid fines of up to 5,000 euros.
Secure state funding of 80% for vehicle conversion and 40% for charging infrastructure until August 31, 2025.
Retrofitting existing vehicles (DTE) is often more economical than purchasing new ones, reduces the Total Cost of Ownership (TCO), and promotes a circular economy.
The logistics for night operations faces a dual challenge: rising diesel prices and strict noise protection laws. Many municipalities and companies are confronted with fines and the pressure of the Clean Vehicles Directive, which mandates a quota of 65% for clean buses by 2026. This article demonstrates how to reduce the noise level of your fleet for night operations by switching to electric vehicles. We explain the path from analysis to the utilization of state funding of 80% for vehicles and 40% for the charging infrastructure, with the application deadline ending on August 31, 2025.
Legal Pressure to Act: Why Quiet Fleets Are Becoming Mandatory
The operation of diesel vehicles between 10 PM and 6 AM is often a regulatory offense in residential areas, punishable by up to 5,000 euros. The Federal Immission Control Act (BImSchG) sets clear limits here. At the same time, the Clean Vehicles Directive (CVD), implemented by the Clean Vehicles Procurement Act (SaubFahrzeugBeschG), obliges public clients to fixed quotas. By the end of 2025, 45% of all new buses and 10% of trucks must be “clean”; from 2026, these quotas will increase to 65% and 15%, respectively. The conversion to electric drive is no longer an option but a strategic necessity. Quiet electric vehicles not only enable compliance with nighttime operations but also meet the increasing requirements for emission-free procurement. These regulatory drivers make the transition predictable and urgent.
Your 4-point action plan for timely fleet electrification
A structured approach is the key to not missing the deadline for the attractive 80% funding on August 31, 2025. With this checklist, you navigate safely through the process:
Conduct needs analysis: Record the daily routes and mileage of your fleet. Our experts will help you define the vehicle requirements profile for vehicles like the Heero DTE-Sprinter with up to 425 km range.
Review and apply for funding: The current BMDV guidelines subsidize the Diesel-to-Electric conversion (DTE) by 80%. We accompany you through the application process to secure these funds before the deadline in August 2025.
Plan charging infrastructure: Parallel to vehicle funding, you can receive a 40% grant for the establishment of operational charging infrastructure. A Heero Tourer charges with up to 135 kW, which requires careful planning of the charging capacity.
Select implementation partners: Rely on an experienced partner who offers the conversion to electric drive as a core competence and embodies the principles of circular economy.
This plan ensures that you not only reduce the noise level of your fleet for night operations but also fully utilize economic support.
Total Cost of Ownership: Why Retrofitting Outweighs New Purchases
The decision between retrofitting and purchasing new depends on the Total Cost of Ownership (TCO), which considers all costs over the lifetime. A DTE retrofit is often the more economical choice. While the acquisition costs for new electric commercial vehicles are high, retrofitting protects your existing investments in expensive special superstructures. Studies show that electric vehicles already match or undercut diesel vehicles in overall operating costs. The reason lies in the maintenance and energy costs, which are reduced by up to 70%. Furthermore, retrofitting promotes circular economy by extending the lifespan of proven vehicles such as the Mercedes-Benz Sprinter and avoiding CO₂ emissions from new production.

HEERO-Technology: Performance and range for professional use
Our DTE solutions are based on the proven technology of the Mercedes-Benz Sprinter and are optimized for demanding tasks. The ranges have been tested in practice and cover most application profiles.
Heero eTransporter: Up to 500 km range for long delivery tours.
Heero DTE-Sprinter: Up to 425 km range, ideal for service and craft operations.
Heero Tourer (Minibus 9 Pax): Up to 400 km range for quiet transport of people.
Heero low-floor bus: Up to 300 km range and fast charging with up to 165 kW DC thanks to a 137 kWh battery.
All models except the low-floor bus use a 110 kWh gross battery (96 kWh net) and charge with up to 135 kW. This performance ensures that your vehicles are fully operational again after a short charging time. The conversion also significantly enhances the driving comfort through the stepless drive.
Funding pots secured: 80% subsidy only until August 2025
The time to take advantage of the maximum funding is running out. The current funding program of the Federal Ministry for Digital and Transport (BMDV) is coming to an end. Applications must be submitted by August 31, 2025, to benefit from the exceptionally high quotas. Here are the facts:
80% of the additional investment costs for the purchase or DTE conversion of an electric commercial vehicle will be covered.
40% of the costs for the establishment of non-public charging infrastructure are also eligible for funding.
This combination makes the switch currently as economical as never before. The funding is a clear signal from the federal government to accelerate market ramp-up and support companies in their transformation. Do not wait until the programs expire or the funds are exhausted. Act now to future-proof your fleet and meet the requirements for zero-emission zones.

FAQ
How long does a Diesel-to-Electric conversion take at Heero?
A typical DTE conversion of a Mercedes-Benz Sprinter takes us about 10 to 15 working days. We ensure a quick and efficient process so your vehicle is back in operation swiftly.
What range can I expect from a converted vehicle?
The range depends on the model. Our converted Heero DTE-Sprinter achieves up to 425 km, while the eTransporter even reaches up to 500 km. These values are designed for most daily operational profiles in logistics, trade, and municipal services.
Does Heero assist with applying for funding?
Yes, we offer a free funding analysis and actively support you during the application process. Our goal is for you to receive the maximum funding of 80% for your vehicle and 40% for the charging infrastructure before the deadline on August 31, 2025.
What does Total Cost of Ownership (TCO) mean?
Total Cost of Ownership (TCO) includes all costs incurred during a vehicle's entire lifespan: acquisition, energy, maintenance, insurance, taxes, and residual value. Electric vehicles often have a lower TCO than diesel, as their energy and maintenance costs are significantly lower.
Does the warranty of my base vehicle remain valid after the conversion?
The electric drive components we install come with their own Heero warranty. The original manufacturer's warranty for untouched vehicle parts usually remains valid. We clarify details transparently in advance.
What charging capacity is required for the converted vehicles?
Our standard models charge with up to 135 kW direct current (DC), the medium-low-floor bus with up to 165 kW. This means the batteries are charged to 80% in about 30 to 45 minutes, minimizing downtime.
