Hyundai Mild Hybrid MHEV Powertrains Explained

Автокөліктер мен көлік құралдары

Short video from Hyundai explaining how their Mild Hybrid or MHEV 48v hybrid powertrains work. In short, a mild hybrid car works in a very similar way to a self-charging hybrid car, but it has a smaller battery. Because the battery is smaller, a mild hybrid cannot drive on battery power alone - unlike a self-charging hybrid in which the motor can take over at low speed or when cruising.

    ive heard that it increases the tork so helps acceleration but how can it do that if the engine isnt driven by a motor

    The mild hybrids (MHEV) don't have enough battery power to add any more power/torque. The slightly larger battery helps with the stop/start, so improves the efficiency and economy slightly. The Hybrid cars have larger batteries and electric motors, so that's where you see improved Torque.

    @@rpatel9901 It depends on which model year you're talking about. Before the MHEV engines, the regular engine as you say, was 100PS, but the newer MHEV engines in the later models are also 100PS. The 120PS engine, found in the N Line, has better tuning. So the power hasn't increased due to MHEV.
