Nissan Qashqai 2023 Owners Manual
7.14. Mild Hybrid system technology (where fitted)
Mild Hybrid system technology efficiently controls torque assist function and battery charging (energy regeneration function) and enhances the stop/start function to improve fuel efficiency. The system makes use of a dual battery system: 12v lead-acid battery (main) and a lithium-ion battery (sub) are installed. These batteries store the energy generated during braking to assist the engine's idle start-stop and the torque assist functions. The energy stored in the Lithium-ion battery assists during acceleration which helps the engine in providing optimal acceleration and performance.
When the vehicle is coasting without pressing the accelerator pedal or when decelerating by pressing on the brake pedal, the batteries are charged, storing the energy generated.
When the battery charge is sufficient, the energy can then be used to assist the engine for to 20 seconds during acceleration, helping to provide optimal performance and fuel efficiency.
The torque assist function will not be activated under the following conditions.
When reverse (R) gear is selected.
(Manual Transmission only) when the clutch is not fully engaged (clutch pedal not fully released).
When abruptly starting or accelerating.
When the brake pedal is pressed after starting to accelerate.
When the accelerator pedal is released after starting to accelerate.
When the anti- lock braking system (ABS) or Electronic Stability Program (ESP) are operating.
When the battery capacity is low.
When the outside temperature is low and battery protection is required.
