It is necessary for us to reduce CO2 emissions in order to hold down global warming which is advancing year by year. Toyota believes that it is important not only to introduce BEVs but also to promote technological development of HEVs and PHEVs in order to widely reduce CO2 emissions around the world. This time, we have developed a PHEV system for Prius. The traction battery Pack structure, the transaxle and the power control unit (PCU) with boosting converter system were newly developed based on the 2.0L hybrid system, resulting in 1.5 times the battery capacity with the almost same battery pack size and transmission efficiency has also been improved, extending EV distance by 70% from previous Prius. In terms of power, by adopting Double-Boost converter system and increasing the motor output, the system output power has been increased by 1.8 times with almost the same size as the previous unit.
