Watch As Tesla Model 3 Battery Is Removed And Disassembled


This pack has more than just batteries

EVTV has been putting out videos for nine years, now. The effort began with an emphasis on converting existing vehicles to electric drivetrains, but eventually it spent a lot of its energy focusing on batteries — both testing and selling them, along with other components.

More recently, its done a lot of work with Tesla drivetrains, and so it’s no surprise that it has gotten a hold of one of first salvage Tesla Model 3 vehicles to show up at an auction. In its latest episode, EVTV principal Jack Rickard and assistant Bill Bayer remove the pack from its home on the underside of their acquisition and remove the cover to learn about what lies within.

Before the pack is divorced from the car’s chassis, we learn one of the things that separate it from the energy box found beneath the Model S: it’s not designed with the battery swapping as a future possibility, it a lot more difficult to actually disconnect and extricate it from its snug home. The differences don’t stop there, either.

Unlike the S, and pretty much every other electric vehicle we’ve seen disassembled, the Model 3 has its AC charger and DC to DC converter inside of the battery pack. Typically, those are components found under the hood. There are advantages and disadvantages to this approach. On one hand, it might speed up the car assembly process. On the the other, if one of these components goes bad, the time and cost to fix will be elevated.

As is typical of most EVTV videos, this one weighs in at a significant hour and 24 minutes, and it’s not unheard of for people to find Mr. Rickard’s presentation style to fall short of highly engaging. So, if you’d like the TL;DR version of the video and its finding, YouTuber Jehu Garcia has a summation piece that comes in at less than nine minutes, which you will find below. Enjoy!

2. Tesla Model 3
Range: 310 miles; 136/123 mpg-e. Still maintaining a long waiting list as production ramps up slowly, the new compact Tesla Model 3 sedan is a smaller and cheaper, but no less stylish, alternative, to the fledgling automaker’s popular Model S. This estimate is for a Model 3 with the “optional” (at $9,000) long-range battery, which is as of this writing still the only configuration available. The standard battery, which is expected to become available later in 2018, is estimated to run for 220 miles on a charge.

And they find what stunned the German OEMs when they disassembled their Model 3s–Very high quality electrical components as the core of a compelling EV meaning battery and battery pack plus BMS, inverter, motor, etc.

Look at the Chevy Bolt battery disassembly as see how much simpler it is to assemble and disassemble.

EVTV – LOL – a bit less “structured” on their teardown – not exactly Weber State-precision – .

I thought (according to the article) the Germans commented on the power electronics – a part that is not in the battery itself. The module you can see under the hood, on a car that is converted from ICE to electric. There did not seem to be anything special about the electronics, cables or modules here. I don’t think the motor(s) are anything special either. I think they have made some of the power electronics smaller, simpler and cheaper somehow. I’m sure there will be a complete tear down of a Model 3 soon, that will go into detail of each and every part. If they compare it to another model part for part – that would be awsome. What would be cool is if another car company (like Nissan that make EVs) did a complete tear down, and the engineers talked about what they saw, what they did different, what looks cool, new, better/worse.. all the stuff they (Nissan or others) would normally not reveal to the public. Then explain truthfully why the different solutions was used. I was on a training course, of different equipment/machine in Amsterdam – where the highly skilled, lead instructor told us straight: This… Read more »

Favorite line: “We’re one camel-sneeze away from going vertical on the electric cars.”

“Unlike the S, and pretty much every other electric vehicle we’ve seen disassembled, the Model 3 has its AC charger and DC to DC converter inside of the battery pack.”

More specifically (although I didn’t watch the whole video) — looks like they are in the “penthouse” section on top of the aft part of the battery pack — which looks to be underneath the rear seat of the vehicle. So, …. could you access through the cabin by removing the rear seat and taking the cover off the penthouse ?

wouldn’t that make more sense than dropping the whole pack ?

Yeah. That was my thought too. The big pack disconnect, for the Bolt pack, is accessed by pulling up the rear seat cushion. I don’t see why you couldn’t do the same for that “penthouse” cover.

On the other hand, to get to the BMS on the Bolt pack, which is also located up there, you have to drop the pack.

That’s a great point. I need to investigate this further.

I’ve never actually heard of an AC charger failure in any electric vehicle at all, much less it being a wide-spread problem that would actually impact a significant number of EV buyers.

I remember a bogus meme a decade ago fabricating some great fear of AC Chargers failing and burning down people’s houses as they sleep. But like most FUD, no such wide spread problem ever became a reality.

Seems like a non-issue. But I’m sure it will by hyped by some of the same folks with the same mentality who spread the original FUD that all electric cars were a fire hazard due to AC Chargers overheating and burning down garages…..

“I’ve never actually heard of an AC charger failure in any electric vehicle at all…”

Here’s a thread on a Tesla that had the onboard charger R&R’d ,… that took me all of 30 seconds to find.

Chargers can definitely fail. I know Zero Motorcycles (I know, totally different company) had a problem with this for a while.
