According to foreign media reports, as more and more customers seek to reduce their carbon footprint, Scania, the Swedish truck and bus manufacturer, announced the launch of hybrid and pure electric concept systems. The system uses a compact design, but achieves excellent performance. All components can work together seamlessly, controlled by a common management system. The single system management interface CAN J1939 and the single mechanical interface SAE 1 will remain unchanged, thus simplifying its integration with external components.

Scania's system is both a modular system and a scalable system, allowing customers to select and combine some components according to the application and specific needs.
Scania's hybrid electric system combines an electric motor and an internal combustion engine. The two devices can work together or as an independent power source, which can reduce carbon dioxide emissions by up to 92%. The hybrid electric system can be effectively used in excavators, dump trucks, stone crushers, mobile cranes, concrete pumps and airport fire fighting equipment; it can also be used in marine equipment such as commuter ships, road ferries, pilot boats and fish farm support ships.
In addition, the hybrid solution can improve the performance of the power system with excellent torque capability and direct idling response capability, significantly reducing fuel consumption, while reducing operating costs, noise and emissions. Because the motor is installed on the engine and its speed range can be matched with the engine, there is no need to install additional gearboxes to minimize energy loss and facilitate equipment installation and design. However, its compact design also facilitates installation .
If all are generated from renewable energy, Scania’s pure electric system can reduce carbon dioxide emissions by up to 98%, and vehicles such as stacker trucks, straddle carriers, dump trucks, excavators, loaders, airport fire fighting equipment, etc. And equipment can benefit from the system; marine equipment such as sightseeing ships, road ferries, wind farm support ships and patrol boats can also use the system.
The pure electric system is powered by an electric motor, with excellent power density, maximum torque and direct start response. In addition, due to high energy efficiency and low maintenance requirements, the cost of operating the system is also low. (Yu Qiuyun)
