Electric zero-emission truck

Control network is based on J1939

Many of the ancillary systems that are traditionally driven by the engine were also electrified, including the air compressor, power steering and HVAC system. The controls were integrated into the vehicle’s J1939 network.

Toyota has announced the next great leap towards the future of zero-emission trucking by unveiling the second iteration of its Project Portal hydrogen fuel cell electric Class 8 truck. The ‘Beta’ truck significantly exceeds the capabilities of the ‘Alpha’ demonstrator vehicle revealed in 2017, increasing the estimated range to more than 480 kilometer per fill. The truck also enhances versatility and maneuverability with the addition of a sleeper cab and a unique fuel cabinet combination that further increases cab space without increasing wheelbase. For both the Beta and its predecessor Alpha vehicle, Ricardo assisted Toyota with a wide range of engineering functions. These included systems integration and packaging, including the fuel cells, power electronics, hydrogen tanks, cooling systems, batteries, electric motors and transmission.

“The Ricardo team is pleased to have been able to continue our successful collaboration with Toyota on the very important Project Portal heavy duty zero emission fuel cell electric truck demonstration project,” commented Chris Brockbank. “The Beta Project Portal vehicle is an impressive advance over its Alpha predecessor, offering practical design improvements in addition to its very practical 300+ mile range which makes it a capable ZEV option for drayage operations. We look forward to working with Toyota in the completion of the real world drayage testing, and to seeing the results of the project which, I believe, may well inform the future vision of heavy duty transportation.”
