Weber State University (WSU) - Department of Automotive Technology - Ardell Brown Technology Wing - Transmission Lab.
This episode covers the removal, components, and operation of High Voltage Hybrid Inverters and Converters - Specifically the 1st and 2nd generation Toyota Prius Inverter with Converter Systems. These systems are the foundation of almost all other hybrid control systems used by other manufacturers.
Join us for hybrid and electric vehicle training with two online courses and in a 5-day on-campus boot camp with Professor John D. Kelly. See www.weber.edu/e... for more information.
This topic is taught as part of our 4-year bachelor's degree program. For more information on the Weber Automotive program, visit: www.weber.edu/a...
This video was created and edited by Professor John D. Kelly at WSU. For a full biography, see www.weber.edu/a...

You're doing a great service to the community by putting these videos on youtube. These hybrid system videos are higher quality than any paid online training I've seen. Amazing work.

@@WeberAuto Hi, just curios, but if you were driving along on a busy road or motorway and for what ever reason with the Prius and 1 or 2 modules went dud would the petrol engine still get you home or would it cut out and therefore as you mention some where in one of your answers to someone would also not be able to turn over to start once it came to a stop? I know a BMW i3 extender model only has the little generator engine at the back but in the same event may not succumb to the same battery failer because all it is doing is pushing out the same or even up rated charge due to sensor differentiation still with a constant charge to the main battery be it at a lower power rate but would still get you home!?

Professor Kelly, I got a super super great deal on a 2007 Prius that was extremely high mile but needed some minor mechanical repairs. I stumbled on you channel cause I really wanted to learn how this and any hybrid models works. You've taught me a great deal!! It's like Netflix binge watching I go from one video to the next. For me you solved a lot of the hybrid mystery and when I need the next vehicle it WILL be a hybrid!! Thank You again for sharing your knowledge!!

@ablackformula 6 лет назад

you should always test live, dead, live. imagine you tested 0v at all high-voltage points, only to find out with bare hands that it was indeed energized, but your test leads were faulty or not plugged in all the way to the voltmeter? the 12v battery in the trunk would be a good place to make sure the voltmeter works, both before and after testing the high-voltage at 0.

You, AgentJayZ and EEVblog together make up the equivalent of an entire virtual university! Could you perhaps make a video showing and explaning your procedure to disassemble something for the first time? Showing the labeling process, the label confection, what one sould label, photograph, what one could relay on the videos alone, etc. It would be of great value!

@Luzt. 5 лет назад

Professor your're probably no. 1 ressouce regarding EV technology. I'd like to caution you in the area of using statements like "booster raises voltage to increase power".The power available is, to a first approximation, determined by battery size (weight). Any subsequent change in voltage/current can only diminish this power due to lossess during conversion. It would be better to say "the booster increases voltage to the level optimal from the point of view of power electronics and electrical motors while keeping battery voltage at/around its optimal voltage (number of cells which need individual management, number of connectors, reliability issues)".

@WeberAuto 5 лет назад

You are absolutely correct, I stated that incorrectly. Thanks for your feedback

@Luzt. 5 лет назад

As a late arrival to "Washine-machine" powered automobiles and vans, your videos are helping me to adjust (understand) from 45yrs of Diesel and spark ignition marine, generator and automotive engine installations to the application of 3ph power into basic transport. Out of choice I'd rather have a rotary diesel injection pump and mechanical injectors, but the envioment and in the UK and I guess now in the US, politics dictates the move to purchase electric.

Thank you Sir for all your clear explanations. In fact you took off all my apprehensions concerning hybrid systems and maybe this will even save my workshop. In fact there are running more and more of these Toyotas on Reunion Island where I live and the french government, as well the EU as a whole, is determined to eliminate diesel vehicles which I am specialized in. So I think I will invest in new equipment and more training on this type of cars. Thanks to you for a good part.

@gregyohngy 4 года назад

You mentioned about the inverter overheating caused by a loss in coolant. My Prius is losing coolant. The cause is probably due to the hoses and not the inverter itself leaking? I did replace the inverter coolant pump three times before getting a Gates brand replacement pump. The Amazon $55 replacement pump lasted 6 weeks and less than a month.

A relay has a common and a Normally Open and a Normally Closed contact. A contactor is just a Normally open set of "Contacts". It can be one, two, or three poles and generally used in higher voltage and high current applications. ie 3 phase 208V or 480v.

@aj200415 6 лет назад

Hello John, I think possibly when they were discussing relay/contactor debate, they probably just meant that a relay can also have two "contacts" that pull in like a contactor. A DPDT (Double Pole Double Throw) relay that basically does the same as a contactor would in that instance.

@WeberAuto 6 лет назад

Thank you for your feedback. I understand what you are talking about; however, the "contacts" in contactors typically handle huge mounts of current. The "contacts" in relays typically handle smaller mounts of current. I am sure there exceptions, but in hybrid and electric vehicles, contactors are used to control the current leaving and entering the high voltage battery, not relays (even when they are called "relays" in schematics). I hope that helps.

These are a big help for someone like me who is already a working tech but needs additional training to keep up with all the new vehicles on the road. I apologize if you cover this in other videos but can you recommend a video or just some literature I could use to learn about data pids and expected values I should expect to see in order to determine the condition of the hybrid battery and how the system is operating to determine faults. Any help would be appreciated and thanks again for these videos.

@TheDansana 2 года назад

Thanks for your explanation of the difference between a relay and contactor. Many sources have many definitions on this, and with each one, I can find an example where the definition fails. Id like to share my definition. A relay uses an electro magnet to bring two or mor contacts together, then releases the force to allow the contacts to open. The failure mode of a relay is often closed as the contacts will tend to stick after many cycles. A contactor used elected-mechanical means to drive the contacts together and pull them apart. This reduces the likelihood that the contacts will remain closed in a failed condition. A contactor will always be used when a failure to open would present a danger to operator or equipment.

@KenBruceWayne 3 года назад

If a contactor is stuck/welded in the closed position, does the high voltage interlock circuit do anything to interrupt the voltage at the contactor or is this just physically disconnecting the high voltage circuit at that specific disconnect point so that voltage would still be present at the inlet side of that circuit?
