Hybrid Electric Trucks

Detailed overview of innovation with sample startups and prominent university research


What it is

Hybrid electric trucks are commercial vehicles that combine an internal combustion engine (ICE) with an electric motor and battery pack. This combination allows them to operate in both electric and diesel modes, optimizing fuel efficiency and reducing emissions.

Impact on climate action

Hybrid Electric Trucks revolutionize low-carbon transportation by reducing emissions from freight. Their dual power system optimizes fuel efficiency, slashing greenhouse gas output and fostering a cleaner logistics sector. This innovation accelerates climate action by offering a tangible solution to mitigate the environmental impact of heavy-duty transportation.

Underlying
Technology

  • Parallel Hybrid System: In a parallel hybrid system, the ICE and electric motor can both power the truck independently or work together. This allows the truck to utilize its electric motor for low-speed driving and regenerative braking, improving fuel efficiency.
  • Series Hybrid System: In a series hybrid system, the ICE generates electricity to power the electric motor, which in turn propels the vehicle. This system allows for greater fuel economy, but it may not be as powerful as a parallel hybrid system.
  • Battery Pack: A battery pack stores energy that can be used to power the electric motor, enabling electric-only operation for short distances and regenerative braking.
  • Battery Management System (BMS): A sophisticated BMS manages battery charging, ensures optimal performance, and protects the battery from degradation.
