That’s why the sticker on the back says “Hybrid Synergy Drive” and not “Battery”.

Yea they make incredible use of a planetary gear set, much more so than the planetaries in an automatic trans. I think it's brilliant they made a flawlessly smooth transitioning device that allows additive torque input from 3 different sources. It runs on simple, normal trans fluid, and it shares a separate coolant loop with the inverter/converter solid state control box. Separate from the engine's coolant I mean. And all this stuff runs north of 300-400k miles before even pretending to have problems. And it's certainly worth the battery cost every decade or two since it pays for itself in saved gas money in 2-3 years.

It gets even more awesome most hybrids including the Prius have an Atkinson cycle engine with roughly 40% thermal efficiency.

This is one of the best explanations of how the hybrid engine works. Superb graphics and dialog make this a must-see for all Toyota Hybrid car drivers, such as I. This documentation was not easy to do and the creator spent a lot of time. It is worthwhile and I thank you for the excellence and passing on the knowledge. Well done.

There is always something special to me about these "sketchy" animation videos. Like they just explain it casually and straightforwadly rather than trying to have a glamorous looking presentation.

Wow this is the first video I've watched that actually makes hybrids make sense.

Probably the best explanation of Toyota's hybrid drive on the internet. Excellent.

I have had a Toyota Camry Hybrid since February 2015. When I drove it away from the dealership, it felt like Star Trek technology to me. After almost four years, it has been 100% reliable with no break downs whatsoever!

Another channel removed and opened up the ICE of a Prius after 200,000miles/300,000km. It was like brand new. The battery and occasionally the inverter coolant pump is about the only thing that can go wrong with these cars.

This a beautiful presentation - Simply brilliant! Your motion graphics spared you the effort of at minimum 5,000 words. I'm subscribed and looking forward to your further efforts. thank you-

What a fantastic video, and amazing use of 3D software! I asked the man in the Toyota shop yesterday how the engine coupled into the wheels along with the motor - did it use a clutch of some sort - and he fobbed me off with utter nonsense. Now I understand! The explanation given here could not be bettered, and the two-motor-generator system with planetary gears has to be the new challenge for youngster to grasp, just as the differential once was. I wonder if anyone has built it in Lego yet! Thanks very much.

I suspect that very few mechanics (even those working at a Toyota dealer) understand how the hybrid system works. It so seldom needs repair that only a few specialists ever work on it, just the rest of the car and things like cooling system, exhaust, brakes, suspension, etc.

Still the best explanation of the Hybrid Synergy Drive I've seen. Thank you.

That's the kind of videos KZread should mainly be used for !

Almost didnt watch this….glad i did. Amazing explanation! I was amazed at the detail and engineering genius in discussion

This is a great explanation. We bought a Prius in 2008, and have been really happy with it. An amazing vehicle. Almost no maintenance, after 151000 miles, and excellent mileage. Lately the battery has shown decreased performance, but we still love it.

Yeah - very helpful video - explains in a way that I can start to physically grasp how it works. You're right it's the pictures that do the trick.

Over the years I've come back to watch this video. This guy really did a great job of simplifying and teaching hybrid this system.

Outstanding explanation .. watched several times to fully understand .. I play at 75%, stop frequently, replay and reflect on the actions inside the planetary element .. a pleasure to learn this. Thanks a million !

This was the best explanation of a hybrid I’ve ever watched!

This is a really good video. Starting off by explaining the problems engineers were trying to solve using clutches and gearboxes sets the context and makes you realise just how amazing the HSD is. Great animation - it must have taken a lot of effort. Thank you.

Absolutely brilliantly done and narrated.

What a great video! Well done, Niels! You have done something which is so necessary: you have used graphics and words to explain CONCEPTS. This is so crucial in explaining the IDEAS behind how things work. Indeed, your are an exceptionally good teacher.

The data presented here blew my mind. So did the illustrations. Great 3d modeling and beaking down of complwx systems. Thank you for this.

I know this is a few years on, but it’s the first time it has ‘come to life’ as it were. You graphics for explaining how the planetary set works is effective - better than the original Toyota presentations. Note that the second planetary set connected to MG2 (the traction motor) is really a fixed ratio reduction set, allowing the motor to run faster. The ‘smaller’ version of this drive (the so-called “hybrid synergy drive” (HSD) ) does not use a chain to connect to the differential gear set - it’s a short shaft from the ‘ring gear’. Although the mechanical arrangement is well described, there’s a bit more to it! In particular, there are three inverters (to work with the motors, which are variable frequency a.c.), and a pair of d.c. converters. The most important battery in this type of car is the high voltage d.c. one - if it’s dead you’ve had it, but if the smaller 12V d.c. one fails, that is easy to overcome with a conventional external d.c. “jump start” device. The contractor for the HSD is Aisin-Seiko - at least 30% of it’s shares being owned by Toyota; it’s own site may be of interest. Also worth noting that the choice of this system is related to the use of the Atkinson cycle for the engine (most of the time), so as to optimise it’s thermal efficiency, at the expense of reduced torque/power at any given engine speed. What is nice about it is that traction motors have maximum torque at zero speed.

I love the little flames in the cylinders. Lovely!

One of the best explanation of how Prius hybrid drive work. very good video🥰🥰🥰

I think it is brilliant to use an generator as a clutch. [that is what MG1 is doing. It is acting like a clutch, all the while it is a generator. The friction that normally would have been lost as heat in a conventional clutch is converted to electricity that runs MG2] Genius!

@ Poker Channel Yeah that's pretty cool. I wonder why hybrid tech isn't more or less mandatory - since it seems naturally more efficient with fuel, in a number of ways.

This is like some of the best powertrain modeling I've ever seen... The detail on just the differential is amazing.

The best explanation I’ve ever seen. Man you are the master of logic and visualization!

Thank you Niels! Nicely produced and animated, give a lot of clarity to my Prius.

This is so phenomenal! Thanks for making this 3D animation.

this is so much easier to understand than explanation on paper. so awesome.

Brillant explanation. I know someone said the same below me, but it´s the expression i found to describe this.

Family has two hybrids, the Mitsubishi Outlander PHEV and Ford Fusion Hybrid, the latter actually employs the same identical powertrain as the Toyota Hybrid Synergy Drive as Ford & Toyota cross licenses patents. The lack of gearshift and no intrusive engine start stop is something that I learn to love in driving hybrids. Even better understanding regenerative braking- no more guilt of riding the brakes and replacing pads & rotors when the MG2 can take it all back and give you more electricity to get even further.

@aluisious

2 жыл бұрын

MG2 cannot "take it all back." You will lose power riding the brakes. Nothing will ever beat coasting for efficiency.

@8:50 is a good quick eplanation of why hybrid gets more MPH: The engine either is running at an efficient RPM or not running at all. Engines apparently have a window of RPM which is most efficient. Hybrids allow for an engine to get away with only running in that narrow window of efficiency.

@MikelSyn

5 жыл бұрын

It's more than that. The engines used on hybrids are atkinson engines. These engines are far more efficient than standard petrol (otto) engines, but at the expense of torque. The motors make up for that loss of torque where required.

thanks, pretty amazing video. I drive a Prius. had no idea it was this complicated.

Brilliant video. Complex engineering made much simpler to understand. I am sure Neils you will give it the required update and revision when required. One of the most informative animations I have ever seen.
