Electric Heavy-Duty truck charging: A slightly different ball game

As the world transitions towards greener transportation, the electrification of heavy-duty (HD) trucks is gaining significant momentum. At Elywhere , we are at the forefront of this revolution, providing innovative solutions with our battery-boosted and stand-alone chargers specifically designed for HDEVs. We are proud to be part of the MegaCharge project, a Green Platform Initiative funded by the Norwegian government and managed by The Research Council of Norway , Innovasjon Norge , and Siva. This consortium, which includes SINTEF Energy Research , Circle K , Tensio , Glitre Nett , Pixii AS , Pratexo , and others, aims to develop high-power charging infrastructure to significantly reduce emissions in the transport sector by 2030. Through this collaboration, we are well-positioned to deliver both our current range and future Mega Watt capacity charging stations, boosted by energy storage, local renewable energy, and value stacking through grid support ancillary markets.

So, why not simply upscale standard EV chargers to accommodate HD truck charging? What's so special about HDEV charging? At Elywhere, we understand that the charging needs of HD trucks and the power ecosystem required to support long-haul and freight logistics infrastructure present unique challenges and require specialized solutions. Here are some of the unique challenges we adress:

Extreme power demand

HDEVs demand significantly more power than passenger EVs, necessitating ultra-powerful DC charging solutions that deliver continuously high power over extended periods. Unlike passenger cars, which experience a falling power demand curve after an initial peak, HDEVs require sustained high power throughout their charging sessions. This substantial power demand presents unique challenges, including the need for robust electrical infrastructure. Energy storage systems (BESS) can effectively address these demands by mitigating peak loads and supplying stored energy as needed. This approach supports HDEVs' extreme charging requirements while ensuring efficient power management and preventing local grids from being overwhelmed.

Grid-friendly solutions

Integrating high-power loads associated with HDEVs can introduce noise and instability to the grid. Advanced grid management technologies are crucial in ensuring smooth and stable operation. Transformers are vital for voltage conversion in charging and power storage systems, but they can introduce harmonic distortion and electromagnetic interference, affecting power quality and the performance of connected equipment. It is paramount to use high-quality power components to minimize noise and ensure reliable performance in the power grid. Additionally, solutions for monitoring power quality and the effect of individual charging stations on the grid are essential. By incorporating BESS, balancing loads, reducing peak demand, and enhancing the integration of renewable energy sources becomes possible.?This?ensures grid stability and supports sustainability goals associated with electrifying heavy-duty transport.

Critical infrastructure

Maintaining high uptime and resilience in charging infrastructure is crucial for HDEVs. Unlike passenger EVs, which can afford extended idle periods, semi-trucks operate on strict schedules where any downtime can significantly impact logistics operations. HDEV charging stations must be reliable and efficient, capable of withstanding harsh environmental conditions and consistently providing performance.

Robust hardware and advanced software are essential to ensure chargers remain operational, minimizing downtime and maximizing fleet efficiency. Predictive maintenance strategies, utilizing power and environmental data, are vital to ensure the durability and operational consistency of these stations, thus minimizing disruptions to logistics networks.

Orchestration of power and fleet management

Managing a fleet of electric semi-trucks requires sophisticated systems for optimizing operations, ensuring compliance with regulations, and?managing?power availability. Advanced fleet management systems offer real-time monitoring, scheduling, and reporting features that enhance overall efficiency. Booking systems are essential for managing charger availability, allowing fleet operators to reserve charging slots in advance, reducing wait times?and?ensuring smooth operations. Energy storage systems help boost charging capabilities during peak demand periods, maintaining the operational flow of logistics.

Additionally, regulations mandate specific resting periods for truck drivers, which?must be synchronized?with charging times. Understanding and optimizing these charging patterns helps in planning and optimizing logistics. Solutions that consider these regulatory requirements enable drivers to recharge their vehicles and themselves simultaneously, ensuring compliance and operational efficiency. Predictive analysis of power availability and synchronization with the arrival times of trucks and their state of charge (SoC) is essential, along with preconditioning the BESS system to be ready for truck arrivals while optimizing energy costs and supporting grid infrastructure.

Conclusion

The transition to electric semi-trucks presents unique challenges, but with the right technology and infrastructure,?these challenges can be effectively managed. Ensuring high uptime and resilience, managing extreme power demands, and integrating grid-friendly solutions are essential for successfully deploying HDEVs. By providing robust and efficient charging solutions, we can support the electrification of heavy-duty transport and contribute to a greener and more efficient future for transportation.
