Transforming Electric Heavy-Duty Trucking with Open Source

The shift to electric power is revolutionizing the transportation industry, especially for long-haul trucks. Four key stakeholders—governments, truck manufacturers, charger manufacturers, and CSMS companies—have significant interests in electrification. The U.S. government's (Transition to Zero-Emission Heavy-duty Vehicles) and the EU's (AFIR) initiatives demonstrate government support, addressing key challenges like charging infrastructure, costs, grid impact, and en-route charging.
Modern EV Charging Station for heavy Duty Trucks

Truck industry accelerates toward electric

Major heavy-duty truck manufacturers are capitalizing on electric trucking's potential, setting ambitious goals for the future:

  • Daimler Trucks with the Freightliner eCascadia and eM2 are poised to reshape North America's market with robust electric drivetrains. Daimler aims to further develop scalable electric solutions and bolster charging infrastructure.
  • Volvo Trucks with its FL and FE Electric models gaining traction in Europe, Volvo targets 50% of its global truck sales to be electric by 2030, while also developing charging stations and smart energy solutions.
  • Scania is committed to zero carbon emissions by 2050, Scania is heavily investing in battery-electric vehicles and expanding its network of fast-charging stations.
  • The Tesla Semi truck, boasting a 500-mile range, aims to revolutionize electric trucking with high performance and safety features, supported by a network of high-speed Megachargers.
  • The R1T and R1S models from Rivian lead in electric utility vehicles, while partnerships with Amazon highlight their focus on efficient delivery and logistics solutions.

Challenges faced by Heavy-Duty Truck charger manufacturers

On the other side we have charger manufacturers for heavy-duty trucks who are facing challenges like the immense strain these chargers place on the power grid, as each unit can exceed 1 MW and require substantial upgrades to handle simultaneous charging. Additionally, the absence of standardized charging technology complicates compatibility across manufacturers and truck models. The lack of standardization also complicates the rapid development of charging stations due to infrastructure establishment delays.

Setting up new charging stations demands high initial investments and requires careful integration into existing grids to avoid disruptions. These costs impact fleet profitability, considering maintenance and future upgrades.

CitrineOS simplifies truck charging with a modular, open-source CSMS

To connect the three main stakeholders (government, truck manufacturers and charger manufacturers) in the heavy-duty truck charging industry, a Charging Station Management System (CSMS) that is adaptable and flexible is crucial.

CitrineOS provides a solution tailored to these needs. This flexible, open-source system supports OCPP 2.0.1, enhancing charging infrastructure for electric heavy trucks by reducing development costs and fostering global community collaboration to encourage standardization.


  • ensures compatibility across diverse trucks and charging stations through OCPP 2.0.1, allowing fleet operators to use any station with ease
  • adapts to fleets of all sizes with its modular architecture, enabling secure and efficient EV charging experiences for users
  • The system lets you remotely control charging equipment, allowing you to manage your charging infrastructure from anywhere to ensure optimal performance
  • enables you can also monitor charger equipment uptime, power levels, and degradation, enabling you to keep a close eye on the health and efficiency of your charging stations
  • manages energy consumption and throughput, optimizing energy use and reducing environmental impact

Ultimately, with support for OCPP 2.0.1 standard, it facilitates easier fleet management and reduces operational challenges, aligning with government initiatives for a greener future. It does not only streamline the adoption of heavy-duty trucks but also fosters collaboration among stakeholders, reducing investment hurdles and enhancing grid resilience.

Support innovation with open-source CSMS

If there is a standard CSMS solution for heavy-duty vehicle charging, it leaves room for more innovation, which can lead to greater adoption and more innovation, such as:

  • V2X: heavy-duty truck (HDT), medium-duty truck (MDT), and school bus in Southern California Edison’s territory showed the potential to earn $7,000 to $12,000 per vehicle annually across V2X use cases
  • Decision making based on data collected for each charging session, providing insights into truck energy consumption, grid interaction, and optimal charging strategies. This data can inform future infrastructure and policy decisions, like for example
  • DMS that involves programs, policies and technologies that aim to reduce the amount of electricity customers use during times of peak demand, often through the use of financial incentives, load shifting or other measures
