The electrification of truck fleets is becoming increasingly important in modern logistics. Electric trucks (e-trucks) offer the potential to significantly reduce CO₂ emissions and reduce dependence on fossil fuels. However, electrification also brings challenges - particularly in terms of the required charging infrastructure. The challenge increases when not just one or two vehicles are to be electrified, but five, ten or even more.
In general, it can be said that it is possible to enter the electric world of commercial vehicles by using mobile DC fast chargers with up to 88 kW virtually via plug-and-play. However, charging times of 5-6 hours and the often limited grid connection capacity put a damper on the ramp-up curve.
Before initiating a complex approval process for transformer houses, fixed locations for fast charging infrastructure (e.g. 400 kW) and extensive ground work at the depot (yard), you should consider how sustainable this decision actually is. Do the planned transformer and the first two fast-charging columns still meet the actual requirements of the fleet at the time of the approved construction work? Is the requested medium-voltage grid connection point even sufficient or perhaps oversized? And above all: Can the associated power peaks be financed? Probably not - which is why such decisions often cause uncertainty in the industry.
The solution: Mobile battery buffer storage with fast-charging infrastructure
As an alternative in the ramp-up phase of e-mobility, mobile battery buffer storage with already installed fast-charging infrastructure could be the answer. These make it possible to enter the world of fast charging infrastructure at short notice and without planning permission. With a minimum grid connection requirement of 88 kW and 125 A, up to five e-trucks can be charged on site. This solution also offers the necessary flexibility: it can be used in rented areas or as an intermediate charging point for regular services.
Another advantage is the dynamic purchase of electricity on the energy market. This makes it easier to calculate costs, as the buffer storage system avoids expensive electricity purchases during periods of high prices.
In addition, mobile battery buffer storage systems can be integrated into existing generation systems such as photovoltaic (PV) or wind power plants. This means that electricity generated in a truly CO₂-neutral way can be stored and used for charging e-trucks. This integration makes it possible to use the available energy directly on site and achieve maximum efficiency throughout the entire energy chain.
Summary: Advantages of mobile battery buffer storage for your logistics
Independence from grid availability:
Mobile battery buffer storage systems enable e-trucks to be charged even at locations with limited grid availability. This makes them ideal for plug-and-play use without major approval procedures or new medium-voltage grid connections.
Reduction of peak loads:
Buffer storage helps to manage peak loads at the depot. They ensure even grid utilization and reduce energy costs by avoiding expensive peak loads.
Increase in charging efficiency:
Thanks to integrated fast-charging stations with liquid-cooled charging cables, charging is faster and vehicle downtimes are significantly reduced.
Flexibility and scalability:
Mobile systems can be used at different locations and can be relocated quickly. As a result, they offer maximum flexibility for your logistics and allow you to test transport routes before full electrification, for example.
Integration of renewable energies:
Integration into existing PV or wind power systems enables the use of CO₂-neutrally generated electricity. This increases the efficiency of the systems and supports the climate-friendly electrification of your fleet.
Future-proof investment:
Mobile battery buffer storage is a long-term solution that helps your fleet on the way to climate neutrality.
Frequently asked questions about battery buffer storage systems
Are battery buffer storage systems reliable?
Yes, the technology is based on proven systems that have been used successfully in the energy sector for years. Modern battery buffer storage systems have comprehensive safety mechanisms such as overheating protection and automatic load control to keep operation safe and stable.
What happens in the event of a power failure?
Battery buffer storage systems offer a reliable backup solution. They can serve as an emergency power source in the event of a grid failure and thus maintain the operation of charging stations and other critical systems.
How economical are these systems?
The initial investment in battery buffer storage is offset by savings during peak loads, lower energy costs and the avoidance of costly grid connection work.
How long-lasting are the batteries?
Modern storage batteries use advanced lithium-ion technology that is designed for thousands of charging cycles. The systems are designed to work efficiently for many years and can be recycled at the end of their service life.
Are they environmentally friendly?
In addition to integrating renewable energies, battery buffer storage systems help to optimize grid utilization and reduce the use of fossil fuels. In this way, they support the path to a CO₂-neutral future.
