im a car guy and never would have guessed that hybrids don't use alternators, thanks for the info
Awesome information thank you
Tanks alot,its good video
Great video very apricieted thankiyou so much
2011 Tahoe Hybrid. Drove myself crazy trying to find my alternator. The kid at the auto store even said my alternator was bad but I don't even have one. Why this info is so hard to find is beyond me. Frustrating.
Nice
Thanks for the info. Therefore what is the risk of buying a hybrid?
Good Info Brother 👍🏽
Does DC to DC covert provide enough power to start combustion engine with completely flat battery?
i have a 09 chevy malibu hybrid 2.4l alternator 13.5v 130 amp can i replace this alternator with a 12v 130 amp alternator because i cant seem to find the right one anywhere
Wonder if the ASE A6 has many hybrid-related questions
well explained
What's the serpentine belt for on a Gen 2 Prius?
It was originally named "alternator" because it generates alternating current, which the "spinning mechanism" as you call it still does. It can be rectified on board or divorced, doesn't matter, it still generates AC.
Does the DC - DC converter only work when the car is running? Shouldn’t;t I be able to start my car from the High Voltage source if the 12v battery fails?
No, charging amperage is usually low. Starting a car takes upwards of 200Amps
Toyota Prius 2005 13,8 V car ON . When I turn on all electrical devices in the car - the voltage drops to 12.5 V. Does this mean the alternator is broken.The alternator is holding constant voltage, there are no voltage peaks.
Today my Prius boiled acid in the battery. What can be the reason. Defective battery or alternator.
I have a 2010 Toyota Prius with 130K milage. I replaced the 12V battery 4 months ago. Again with the same problem before the car will not start. However, I can start the car when jumping the 12V battery. It might be the dc/dc converter or the big battery for possible problems.
Hi Dave,
Thank you for your insightful tips and taking the time to do these videos. I am a TH-camr as well and understand the effort that goes into these videos.
We have a 2008 Honda Civic Hybrid and i have know for 2 years that the battery is done. just yesterday the alternator will no longer charge the battery.
Can you please let me know how to change what ever needs to be changed or whether i am even able.
Thank you again,
Mike from Calgary
What did you do? I have the same issue
@@renebarcenas5106 Did you figure out a solution? I am having same issue
So whats it rated at 100 amps 200 amps?
Hi, my 2015's dash lights arent coming on at all. No response from anything . I put a battery charger on it and its was at 87 percent. I charged it to full and still nothing. Any thoughts?
Clean connection and ground to car connection gets rusty.
WRONG! ALL "mild hybrids" have alternators, but often they are very large and are also used in reverse as a 3-phase motor to add to crankshaft power. Examples: 2007-2010 Saturn Vue Green, Aura Green, Chevrolet Malibu, Buick eAssist Regal and Lacrosse... to name only a FEW. In many of these, this same Alternator/Motor also serves as the Starter motor via the same oversized crank connected belt drive.
2011 Ford fusion hybrid was told has no alternator could be DC to DC converter issue.
@@Mike-dq9cr Every Hybrid uses an alternator to charge the HV battery pack using power from the ICE power plant. This same alternator is also used to start the gas engine... so the Alternator can operate bi-directionally in energy conversion... rotational energy to electricity, or electricity to rotational energy.
An "Alternator" is the technically correct. term used to describe the process of converting rotational energy to Alternating Current electricity... AC power. Even in a common "emergency generator" used to power a house during failure of the AC grid, that "generator" technically uses an Alternator... NOT a "Generator"... which describes generation of DC power.
However the two words get used interchangeably when describing hybrid functions... it's not technically correct, but it's common.
This has resulted in the creation of the term "motor-generator" when discussing hybrid and electric vehicle operation... since even in a pure electric vehicle, the drive motor (which is AC driven), also operates as an alternator/generator to push power back into the EV HV battery pack during regenerative braking. (hybrids also use regen braking)
In modern hybrid vehicles, the Alternator resides inside the transaxle, where it has access to the crankshaft of the gas engine... so it has the ability to either apply rotational torque TO the crankshaft (to act as a "starter motor"), or to convert the gas engine rotational power into the required HV DC power to charge the hybrid HV battery pack while driving.
"Mild hybrids" have no special "Hybrid transaxle", and this "alternator/motor" or "motor/generator" is mounted to the gas engine, driven from the crankshaft by a wide serpentine belt. In this "mild hybrid" type of application, the alternator/motor usually is capable of 25hp or more.
A typical common gas-engine 12v alternator is only capable of maybe 1500 Watts of power generation... which is only 2hp.
WeberAuto channel is a great learning resource on Hybrid systems. He has a video comparing 1st, 2nd, and 3rd generation Ford Hybrid transaxles... "Ford Hybrid Transaxle Generations"
Thanks for the video.
I have lexus rx400h hybrid, and it shows 13.3v when vehicle is switched ON. is there anyway we can increase that 13.3v to 14.0v in these particular vehicles? because it seems like battery not charging up enough at 13.3v. please help thanks.
Does the 12v batt charge when the vehicle is in hybrid mode??
Yes it does.
Is that the catalytic converter? If that was taken by someone who installed a shield. It can cause a battery to die?

Anyone here trying to figure out if adding an amplifier will ruin your hybrid??
On an 05 hybrid I need to change the serpentine belt but it doesn’t have a tensioner. Is there a simple way to replace this or is it a pain in the rear?
A drive belt tensioner is used to keep the proper tension on your vehicle's serpentine belt. In short, I see it as a pain in the butt. Though you can always check your local shop for help, and there is a neat video called, "How to Replace Serpentine Belt Toyota Prius 2003-2009" that might have a few tips or a solution to your problems. I hope that helps.

AVI ON DEMAND thank you very much!
where is the dc converter located at
Young Mylle
Put a pulley where the center cap of the wheels go and hook up an alternator to it you'll have endless electricity
Lol. I’d see that on a you tube video. It was crazy
Not a very video of explanations. My honda civic 2008 hybrid has great voltage but no assist ,zero bars now. It is only charged at 13.6 volts while the rpms are at 2000 rpms and the car battery light is on now also. p1570 code which is hybrid battery . You did not say how to test the dc to dc or where it is located...very low info video ,very dissapointed.
Alernarter
Come look at this thing in my 2009 honda hybrid that Rock Auto get over $500 for!🤣
Anyone help!? I have a 2005 Honda Civic Hybrid and the battery keeps dying, but my Hybrid battery gauge shows that the Hybrid battery is fully charged. And since is no alternator would that be a reason why my battery is dying and won't start? Because I get it jumped and it runs it just has a hard time kicking back on. Someone help!
Good evening,
In all sincere forms of honesty, you might as well sell the car. To fix/replace the batteries is not going to be cheap, even if it was a newer model, and even then you have about another year. Unless you are in love with the car, it is far more sane to sell your vehicle to a dealer then proceed with repairs.
Good luck with your future endeavors!

Wait hold up? I got a new battery 120 out the door and she runs better then she did with the old battery lol. Wierd but ok.
@@killjoy69691 I have the same issue, so you replaced the 12v battery? Or the hybrid battery? Please advice
@@renebarcenas5106 I replaced the bat and it was all good after
And he said sell your car 🤣🤣💀💀🤣🤣
Not true for all hybrid. There are "spinning" generators that do the same job
Let's add an alternator back into the car. Problem solved
