Understanding the Bolt EV

We are finally moved into our new building after a very long summer/fall without access to my cars, parts, cameras, etc. This is a custom video I made for the Doutor-IE event in Brazil on December 4, 5, and 6 2020. The Doutor-IE Circuit is the largest event of technical content for professional automotive repairers in Brazil. Yes, I know my glasses are crooked in the introduction ;)
CORRECTION: The Bolt EV does use a radiator in the Power Electronics cooling loop, but not in the High Voltage battery cooling loop. See my Bolt EV cooling system video at • Chevrolet Bolt EV Cool...

    The Bolt EV is a lot more complexed than one would think. You naturally think of a motor and a final drive. But when you stop and think you realize it needs a inverter, control module, a charger system, and a heater for the cabin. You did an excellent job explaining the need for all five boxes and why and how each one works. I've been a mechanic most of my life. (I'm now retired and almost 70 years old) I know all the moving parts in an internal combustion engine, and a manual or an auto transmission. I still like the thought of an EV because there is only one moving part in the motor. (the armature) and the final drive is a lot less complexed than any transmission, manual, auto, or CVT. I like this thought so much that my next car will be a Chevrolet Bolt EUV. I considered the Nissan Leaf, but it doesn't have enough range. I do not the looks of a Tesla Model 3 and I think it's dash is stupid looking. I know there are other EV's and more coming, but the Bolt EV does what I need and has an affordable price tag. Thanks for sharing your knowledge of the Chevrolet Bolt EV.

    That's gearhead DNA ! Tesla's are innovative and have some great engineering behind them, but for me the price is out of the question. Also I worry about long-term maintenance with Tesla. A used bolt is my choice for my next EV. I've had a 2015 Fiat 500e and BMW i3 for 4 years. The Fiat has been trouble free, the BMW less so (suprise!)

    It's incredible how the computers and the high power electronics perform the power flow to and from the drive motor, and the main battery thousands, if not millions of times per second to provide torque and also the regeneration back to the battery as minute and split second changes in the "accelerator" are made to take advantage of the near instant torque and regenerative breaking. Absolutely incredible ! And to get 250-300 miles of range is amazing !! Amazingly quiet and smooth ! And no nasty exhaust !

    Dr. John - I figure that if you have analyzed every hybrid and EV out there, and chose the Bolt for yourself, it's a great car. And at the price, it's a great value. I may just wait for the tax credits to be renewed. I'm bothered by the control that Tesla has over buying parts, using only authorized body shops which take months for repairs, and some quality issues as this month's Consumer Reports mentions. I watch Rich Benoit (Rich Rebuilds) on You Tube and after establishing an independent garage for Tesla repairs, he is now soured on the brand. There is a video on You Tube on how to charge the Bolt on the Tesla Network for free.

    Hi, I have been driving a 2019 Prius Prime for the last 3-1/2 years. If you do get a Bolt, or any other EV, you will likely learn some rather different driving techniques. One of the most important: to get the best performance out of the Regenerative braking system, you will learn to begin decelerating much sooner as you approach a stop sign or red light. You want to drive the car in a way that uses the friction brakes as little as possible, and to capture as much energy as you can from regen braking, that means having a very light foot on the brake pedal. Once you get used to it, you'll never want to drive a gas car again.

    Professor Weber, based largely on information from your videos, I searched for and bought a used 2017 Bolt EV with some minor body damage that had the propulsion battery recall work done. Since it has been repaired it has become my primary vehicle and I can safely say it is probably the overal best automobile I've owned, and the first domestically made vehicle I've purchased since the Chevy I had in high school. I convinced my wife ten years ago that we should have solar panels and battery storage on our home and at the time I someday hoped to have an electric vehicle to take advantage of the installatiion but had no idea when and how that would happen, The Bolt made it possible on our budget. I don't think I could ever go back to an ICE vehicle. I sure don't miss oil stains on the floor or the smell of exhaust in the garage. 🙂 As far as I am concerned you are performing a public service. Thanks so much!

    I really appreciate this video series. I googled "what's inside a Bolt EV" and found a few reviews of the interior of the car, but THIS is what I was actually looking for. I now know everything I need to know as a prospective owner of one of these vehicles, and the information was clear, digestible, and presented very well here by Professor Kelly. It's so well-presented that I went from knowing absolutely nothing about the car, to being able to accurately determine things like whether or not the used Bolt EVs I see online have DC fast charging installed just from a glance at a pic of the engine compartment, just from the information I learned here. At around $22k-$24k with a guaranteed $4k used EV tax credit, and if I can find one with a recalled battery so I can get a new one for free with a brand new warranty, the Bolt EV is looking like the best used EV option currently on the market. New Bolts get dealer markups to well over $30k. I can skip those depreciation costs and get a full brand new battery with warranty in a car that I paid used prices for, and I actually know what I'm looking at because now I have an understanding of the tech. Totally changed my buying experience, thanks again.

    First, let me echo the other posters and say, “welcome back”. You are an inspiration! Again, I’m happy to see the use of prime numbers where possible in the driveline gears. Do you ever plan to take a look at the Tesla Drive train? Mind you, Sandy Munro has already shown a lot, but from a completely different viewpoint Call me cynical, but wouldn’t the “maintenance requirements” be a sop to the dealership network?

    Welcome back, Professor Kelly! I've been fixing vibrations with your nvh app while you were gone. For a drivetrain so beautifully simple, how the heck does reverse work? I imagined you were going to say the shifter is just an electronic switch that tells the inverter to swap 2 of the 3 phase ac signals to make the motor rotate in the opposite direction. I'm having a hard time understanding the setup GM decided to use here! Is cable coming off the black box just to control the parking pawl on the mainshaft?

    At GM the "engineering department of mechanical gear selector" was afraid of being without a job in the future so they allied with the "engineering department of huge useless actuators" and convinced management that that costumers would not buy the car unless they could hear gear shifting in a 1 speed gearbox.
