How to Switch Between Hybrid and Electric Modes?
2 Answers
This is generally automatically controlled by the computer, with the engine intervening when a certain speed is reached. Some models allow manual control, enabling direct switching between hybrid and pure electric modes. EV stands for pure electric mode, while HEV represents hybrid mode. Below are the characteristics of hybrid vehicles: 1. Stable Power: With hybrid power, the maximum power of the internal combustion engine can be determined based on the average required power. 2. Energy Recovery: Thanks to the battery, energy can be easily recovered during braking, downhill driving, and idling. 3. Reduced Emissions: In busy urban areas, the internal combustion engine can be turned off, allowing the battery to drive alone, achieving "zero" emissions. 4. Solving Other Issues: The internal combustion engine can conveniently address challenges faced by pure electric vehicles, such as high energy consumption for air conditioning, heating, and defrosting. 5. Cost Reduction: The battery can be maintained in good working condition, avoiding overcharging or over-discharging, thereby extending its lifespan and reducing costs.
When driving a hybrid vehicle, I noticed that the switching is primarily handled automatically by the computer. The onboard system constantly monitors speed, throttle position, and battery level to decide whether to use the electric or gasoline engine. For example, during slow-moving traffic jams, it usually operates on electric power, which is quiet and fuel-efficient; whereas once on the highway or when needing to accelerate for overtaking, it seamlessly switches to gasoline for power support. Some models come with an EV button—pressing it forces pure electric mode for a few minutes, suitable for short-distance movements within the neighborhood. However, be aware that if the battery is low or under heavy load, the system will automatically switch back to gasoline to prevent malfunctions. I observed that the hybrid’s intelligent management is quite impressive, even recycling energy during braking to recharge the battery and extend range. Using these features properly can significantly reduce fuel consumption, but avoid forcing manual switches—letting it self-manage is the most efficient.
