The professor also does other tear-downs of the battery pack.Very detailed and
nicely edited.Danny Ames

2017-2019 Chevrolet Bolt EV Drive Unit disassembly - A Youtube first!
Weber State University (WSU) - Department of Automotive Technology - Ardell
Brown Technology Wing - Transmission Lab.
This is the seventh in a series of videos on the 2017-2019 Chevrolet Bolt EV
W.S.U is a leader in Hybrid and Electric Vehicle education. This topic is
taught as part of our 4-year bachelor's degree program. For information

Class is in session.
If you have ever been curious about the drive unit that puts the Chevy Bolt
[
https://insideevs.com/tag/chevy-bolt/
] in motion, well, wonder no more. Located under the hood of the car, this
component actually contains an electric motor, gears, and some other
components — including two smaller electric motors — needed to make the
wheels of the car turn. In the video above, Professor John Kelly of Weber
State University (WSU) takes the block apart for our enjoyment and
edification.

Now, you may be thinking this just might be the most boring idea for a video
ever. If so, you’d be wrong. Although it can, admittedly, be a bit dry here
and there, you’ll quite possibly find yourself totally drawn in after the
first couple of minutes. Sure, there are no car chases, sight gags, or other
gimmicks. But, there is a certain beguiling quality to the simple act of
discovery and learning that can mysteriously keep you engaged. The WeberAuto
YouTube channel didn’t manage to attract over 100,000 subscribers by
accident.
Before the disassembly action begins, Professor Kelly discusses the motor
and some of its performance parameters in relation to the unit in the Bowtie
brand’s previous all-electric, the Spark EV. The Bolt’s motor produces less
torque, has a lower peak amperage draw, and a higher RPM. Yet, we’re
informed, it actually offers more torque and is a more efficient design.
The professor then takes us on a complete tour of the unit’s exterior,
explaining all the various parts and pieces that are visible from the
outside. With everything clearly labeled, the learning experience begins.
If you enjoyed this video, we would encourage you to take a look back at
