Range Extender Hybrid eCoach
Overview
The 12-metre Plug-in Hybrid Electric Coach (eCoach), the-first-of-its-kind to be designed, developed, and assembled in Hong Kong, can recharge its Lithium Titanate batteries on the fly, thereby fulfiling the busy turnaround cycles required by commercial fleet operators.
As compared to traditional diesel coaches, the eCoach can save at least 40% fuel and reduce 50% emission. Fuel can be further saved if batteries are recharged at the fast-charging stations directly. It only takes 25 minutes to charge up to 80% battery level.

Problem addressed
Regulation on roadside emission is becoming stricter. Although pure electric vehicle realises zero-emission, its range and charging performance is not sufficient to support the heavy commercial vehicle operation which has to fulfil busy turnaround cycles.
Innovation
- Maximise EV driving range by range extender technology
Key impact
- Zero emission under pure electric driving mode
- Achieve up to 50% fuel saving as compared to traditional diesel coach
- Can travel continuously without stopping for recharging, suitable for commercial vehicles in busy operation
Application
- Coach, school bus and circular route bus
- Can operate in zero-emission zones under pure electric mode
