The launch of the new Toyota Prius Plug-in Hybrid represents one further application of Hybrid Synergy Drive® and is Toyota##Q##s core technology platform for the future.
Hybrid Synergy Drive® has been specifically designed to be modular and, adaptable to diverse energy sources, may be readily used in Plug-in Hybrid Electric Vehicles (PHEV), Electric Vehicles (EV) and Fuel Cell Vehicles (FCV).
In the case of the PHEV, the full hybrid system architecture – and its long range capability – remains essentially the same, with a more powerful, externally charged battery significantly extending the all-electric driving range.
When designed as an EV powertrain, it employs a simplified HSD architecture with no petrol engine, compensating through a more powerful electric motor and sufficient battery power to drive the vehicle for several hours before external recharging is required.
Once again driven by a powerful electric motor, the FCV replaces the HSD system##Q##s petrol engine with hydrogen fuel cell technology. With the fuel cells generating electricity to charge the battery pack the FCV has no need of external charging, merely requiring refuelling with liquid hydrogen in the same manner as the Prius HSD system requires petrol.
