    I posted this under Honda forum but I guess many users don't read that forum, so I am posting again. This channel has the best EV drivetrain videos on YouTube.

    BTW the generator on Accord hybrid is 106 kW maximum output (2.0L 143 HP engine), so for Clarity it should be about 77 KW or 103 HP.

    This is great.
    Seeing the actual mechanism like this is much more effective than just looking at diagrams.

  8. Fascinating! Thanks for sharing. But does anyone know why the Clarity BEV with the same electric motor puts out significantly more torque than the PHEV? I would like to see the guy in the video explain that.

    Very interesting. Thanks for posting.

    The motor torque can be easily limited by electronics. If the battery provide more power and the software allows it they can get more torque from the motor.

    Doesn't horsepower = kW * 1.341? If so, 135 kW * 1.341 = 181.035, which corresponds to Honda's 181 hp spec for the Clarity PHEV.

    Nice video. I think I need to pop open the hood and imagine all the gears running inside the housing!
    Also very interesting how so little space was needed to drive the car in electric mode and proved how inefficient ICE really are.

    Because the Clarity BEV has a bigger battery?

    The Clarity Plug-In Hybrid's electric motor puts out 181 hp and 232 lb-ft of torque.
    The Clarity Electric offered only 161 hp and 221 lb-ft of torque.
    I've never read they have the same electric motor.

    My guess is that the BEV and PHEV has the same electric motor. Maybe the plug-in got 20 more HP because of combination of ICE and electric motor?

    In going to think about this video every time it locks in while going 65.

    My next question is how the paddles work. Do they change a gear, inductive resistance, or apply the mechanical brakes?

    @turtleturtle , the paddle tell how much electricity will produce from the generator. Braking is done with inductive resistance.

    More specifically, the paddle applies a consistent deceleration, through regenerative braking. IMO, only useful to me if I was on a long even slope down, which I never am, and if I also wasn't using cruise control. Otherwise it would require constant babysitting of the acceleration pedal to cancel out the constant slowing from the paddle. Some people prefer the paddles more though. Or it might also be useful in mountain driving.

    The deceleration pedal on the floor will also do regenerative braking (with more control rather than three fixed amounts) unless you brake hard, in which case it will use the brakes or some combination.
     
  22. Very informative. One error he makes is stating that Engine Drive Mode engages at a speed of 62mph or above. It will engage at a speed of 45mph or above.

    Regenerative braking is handled electronically through the motor controller. The paddles offer 4, light to moderate levels of regenerative braking. The brake pedal has the ability to offer substantially more regen, under certain conditions. The friction brakes, when active, do not produce regenerative braking energy.

    Another interesting figure from the video, is the 106kW generator. This converts to 142hp. It may be capable of generating 142hp, but not while being driven by a 103hp engine.

    Keep in mind that this is from an Accord hybrid, which incidentally has a 143 hp 2.0 engine! The generator in Clarity and Insight should be around 100 hp.
