Siemens helping fleet operators to decarbonise trucks

Siemens is helping fleet operators transition to full electric trucks in urban areas, but believes the road to decarbonising transport needs to gather pace if the UK is to achieve its goal of zero-emissions by 2050.

Trucks are responsible for a disproportionate amount of greenhouse gases on the EU’s roads. In a study by Transport & Environment, trucks were found to have generated 22% of road transport CO2 emissions yet only accounted for less than 2% of the overall traffic on Europe’s roads.

Countering this imbalance, the EU’s first-ever emissions performance standards for trucks have called for a 15% reduction in CO2 by 2025, and a 30% reduction by 2030 to reduce the dependency on fossil-fuelled transport.

Siemens says that while not on the same adoption trajectory as electric cars or e-buses, technological advancements in haulage vehicles and active innovations in the charging infrastructure are expected to close the gap between electric trucks (eTrucks), electric cars and e-bus adoptions.

Bernard Magee, Director of Electric Vehicle Charging at Siemens, said: “Electric truck charging installations face similar, if not, many of the same operational challenges as e-Bus environments, which have taught us much about the electrification of transport.  These learnings have translated into invaluable insights about the use of optimum charging strategies, efficient grid management and workable financial models.”

As major OEMs introduce more eTrucks into the global marketplace, fleet operators will determine the charging approaches for each use case and weight class i.e. light commercial vehicles, medium and large inner-city vehicles, heavy-duty intercity transports or specialised applications such as electric refuse collection trucks.

According to Siemens, technological and economic factors govern whether slower low-power AC or faster high-power DC charging will be adopted. 

Magee adds: “It’s all about managing the vehicle power demand as efficiently as possible and perfecting a balance that minimises the level of power drawn from the grid. In scenarios where eTrucks such as refuse collection trucks have to work from a predictable schedule: early morning start; return to the depot by the afternoon; restart the following morning. The end of a ‘shift’ provides an ideal opportunity for recharging back at base. Similarly, light commercial vehicles and medium-duty inner city vehicles are likely to have predetermined starts and ends to relatively short journeys where recharging can take place. Heavy-duty intercity transports may require a blend of en route and depot charging. Pantographs – retractable charging apparatus – more commonly deployed in Europe and US, could be deployed for rapid opportunity charging if appropriate, while a mix of cleaner fuel types could be used for covering greater distances.”

Depending upon the location and access to the grid, power infrastructure demands will vary in complexity and design across depots, distribution centres and public stations as the sites come on stream. City centre sites tend to be hampered by space and power limitations, and, on occasions, require innovative workarounds. Rural installations afford the freedom to experiment with grid ecosystems to better manage the flow of energy. 

Magee continued: “Electric fleets demand reliable and resilient power with 100% uptime. Power distribution systems may need to be upgraded on-site or consultation with Distribution Network Operators to add more power lines could all form part of the design process. Meeting this scope of challenge not only requires extensive power and grid technical knowledge but also experience in delivering reliable scalable high-performance solutions on time with limited disruptions – of which Siemens is only one of a few world-class vendors proficient at the planning, implementation and operation of eMobility charging infrastructure strategies.”

Siemens Financial Services offers a range of financially sustainable funding models, which can address both the funding of EV charging infrastructure and the electric vehicles themselves.

On plans to transition its fleet over to EVs, Tino Sakaria fleet manager Fit Out UK commented: “Over the past 12 months we’ve been focused on the environmental impact of our fleet more than ever. Fleet operators can feel that change is coming, and electrification is being pushed, but there’s uncertainty about the sufficient charging infrastructure needed to support an operator. We’re looking to put charge points in all our depots, in partnership with Siemens and we’re working to get our fleet ready for this change. For us it’s about giving our fleet drivers enough time and support to have confidence in the technology so they’re comfortable using it.”

Responding to the electrification challenge faced by operators, Magee concluded: “Pressure is mounting on the transport and logistics sector to embrace and develop clean sustainable transport options. If we’re going to map out a low-carbon future for fleet operators, then early-movers on this journey must take a phased and measured approach with both vehicles and charging infrastructure. Gaining vital experience through small pilots where experimentation can take place and solutions can be road tested, but never losing sight of the endgame: the 100% shift towards electrification. In-depth knowledge and understanding of the power infrastructure and vehicle on board technology will guide your best implementations which is which is why it is so important to do this alongside trusted and experienced partners; ones who understand every aspect of the vehicles, best practices, technology, power generation, policies, profitability, feasibility and maintenance, as well the extended ecosystem. If the UK is to achieve its goal of zero-emissions by 2050, decarbonising transport will need to gather pace.”
