Attractiveness and technical value of PHEVs in the context of decarbonization and electrification efforts
- PHEVs are the most effective means of reducing CO2 emissions during power generation and the evolution of batteries
- PHEVs with EV roots provide new value to cars --> vehicle mobility, V2X, disaster/public assistance

The power of electricity makes for a pleasurable driving experience wherever you go.

This report is based on a keynote presentation by Mr. Takashi Shirakawa, Corporate Officer and General Manager of EV & Powertrain Technology Development Division, Mitsubishi Motors Corporation, at the 6th ReVision Mobility Summit "Find the optimal business solutions to create the future of mobility," held in March 2022. The following is a summary of the keynote presentation "The technological value and appeal of the PHEV for decarbonization and electrification.”

Management of CO2 emissions toward a carbon-neutral society, the evaluation over the entire life cycle (LCA: Life Cycle Assessment) has been shared. In LCA, CO2 emissions during power generation are important, but there are large variations among countries. In the EU, where CO2 emissions during power generation are low, BEVs (battery electric vehicles) are the most advantageous, but in countries where coal and oil power generation is high, BEVs have the highest CO2 emissions, and rather the CO2 emissions of internal combustion engine vehicles are the lowest. PHEVs are most advantageous in countries with moderate CO2 emissions during power generation, such as Japan. In Japan, PHEVs, which require a smaller battery than BEVs for large vehicles such as SUVs, are advantageous, but EVs are more advantageous for minivehicles with smaller battery capacities. Mitsubishi Motors plans to introduce PHEVs (HEVs in some regions such as ASEAN) for large vehicles such as SUVs, and EVs for small vehicles such as minivehicles.

In addition, Mr. Shirakawa introduced the new value of PHEVs as electric vehicles. The "S-AWC" (Super All-Wheel Control) 4WD system, which is electrified, significantly improves the precision of driving force control, torque distribution, and torque vectoring for a more stable driving experience. In addition, the PHEV battery is used to supply power to the external “V2X (vehicle-to-everything): As examples of "Vehicle to X", Mr. Shirakawa introduced the use of electrified vehicles to support the transportation of COVID vaccine by supplying electricity to the moving innoculation vehicles and COVID vaccine freezers, and people who may need medical equipment in the event of a disaster or power outage.
