Four Power Modes

[WestCoastDriver]

Many readers and contributors of this forum are very knowledgeable about the way the Maverick's hybrid engine works.
However there might be a few newbies who aren't plugged in to the amazing way the vehicle handles demands for power, and returns energy to the high voltage battery.

I came across this brief explanation of the different modes power, and wanted to share it:

The heart of the Maverick hybrid transmission system is a planetary gear set (power split device) that connects three key power components: the internal combustion engine (ICE), a smaller electric motor-generator (MG1), and a larger electric motor-generator (MG2). MG2 is directly connected to the wheels and propels the vehicle in electric-only mode and assists with additional torque. MG1 primarily acts as a generator or starter motor for the ICE.

• In electric-only mode, the MG2 motor drives the wheels powered solely by the battery. The ICE is off, and MG1 may hold the planetary gear speeds to allow smooth power transfer. The vehicle moves silently with zero emissions.
• In engine-only mode, the ICE drives the wheels by mechanically engaging through the planetary gear set to MG2. MG1 controls the speed differential by acting as a generator or load absorber to keep the planetary gears balanced.
• In series hybrid mode, the ICE runs but does not mechanically drive the wheels; instead, it powers MG1 as a generator. MG1 produces electricity that either charges the battery or powers MG2, which then drives the wheels. This mode allows efficient engine operation at fixed speed while MG2 handles propulsion.
• In parallel hybrid mode, both the ICE and electric motor (MG2) provide torque to the wheels simultaneously through the planetary gear arrangement. The power split device allows blending forces from MG2 and ICE mechanically.

Mode transitions happen seamlessly with the vehicle’s control unit varying the speeds and torques of MG1, MG2, and the ICE through the eCVT power split planetary system. For example, when accelerating from a stop, the vehicle may start in electric-only mode with MG2 driving the wheels. As accelerator demand increases, the ICE starts and MG1’s role shifts to generator or motor to maintain the planetary gear speed ratio while sharing power with MG2. At steady highway speeds, the system can shift to engine-only or series hybrid mode by adjusting MG1 and MG2 operation to maximize efficiency.
The eCVT planetary gear system allows infinite variation of power source contributions, coordinating the ICE and motors to optimize fuel efficiency and smooth driving dynamics across all hybrid modes.

Cool beans.

Really intrusive in a easy to understand format. Thanks.

Nice explain, I don't think it fully clicked until now that it can seamlessly flow from generation to series, to parallel and percentages in between.
