The Tesla Model 3’s battery pack was given a partial teardown treatment recently, thanks to the efforts of automotive veteran Jack Rickard and his team at EVTV. Rickard, a car enthusiast who conducts electric vehicle conversions, was ultimately impressed with how the Model 3’s battery was assembled, as well as the refinement of its design.

Rickard’s team was able to acquire the battery pack from a totaled Model 3. Upon removing the pack from the vehicle, the electric car conversion specialist’s interest was piqued by the covering of the battery modules. According to Rickard, the sections of the battery pack directly above the Model 3’s 2170 cells had a thin pad that was strangely wet.

This particular section mentioned by Rickard appear to be the “fluff” that Elon Musk mentioned during Tesla’s Q1 2018 earnings call. According to Musk, the fiberglass mats, which are placed on top of the battery pack, became one of the scenarios that proved human hands can work better than robots.

“They’re basically fluff. We tried to automate the placement and bonding of fluff to the top of the battery pack, which was ridiculous. ‘Flufferbot,’ which was really an incredibly difficult machine to make work. Machines are not good at picking up pieces of fluff. Hands are way better at doing that,” Musk said.

Another particularly compelling observation highlighted by Rickard was that the four modules of the Model 3 battery pack were not identical, with two modules featuring 25 cell groups in series and the other two featuring 23 cell groups in series. Rickard’s team did not tear down the battery packs down to its individual 2170 cells, but it was mentioned that each one of the cell groups includes 46 2170 cells that are connected in parallel. Overall, the vehicle appears to have a total of 4,416 2170 cells, at least for the Model 3’s long-range RWD configuration.

The Model 3’s battery weighs 1,054 pounds, which, according to the group, places the energy density of the pack at around 168 Wh/kg. The individual modules of the Model 3 battery are lined with a ribbon-like circuit that goes across the top of the modules and into a BMS board. The BMS boards are sub-boards that are installed on each module, and are, in turn, connected to a main board using only two pins.

Ultimately, the EVTV team was impressed with the Model 3’s battery, with Rickard even dubbing it as the “best battery ever built to date.” The electric car conversion specialist also noted that the Model 3 battery would likely be a favorite among the DIY community. Considering that Tesla is attempting to achieve a production rate of 5,000 Model 3 per week by the end of Q2 2018, Rickard noted that the electric car’s batteries would probably be abundant in the market. This bodes well for DIY enthusiasts like Rickard, who could utilize the modules as batteries for RVs, home battery units, and electric car conversions, among other projects.

Jack Rickard and his team’s observations about the Model 3’s battery are in line with the findings of Sandy Munro during his firm’s teardown of the vehicle. In a recent episode of Autoline After Hours, Munro dubbed the Model 3’s pack as the best in the industry, noting the .2 milliamp differential between each of the battery blocks.

“Nobody can balance batteries that close. Nobody. Nobody’s ever done that,” Munro said.

Tesla adjusts Robotaxi safety monitor strategy in Austin with new service area

The positioning of the driver, as well as the driver’s hands being closer to the steering wheel, is more similar to what Tesla is doing in the Bay Area Robotaxi program than it is to what it has done in Austin.

Tesla has adjusted its Robotaxi safety monitor strategy in Austin after it expanded its service area in the city last week for the third time.

Tesla has been operating its Robotaxi platform in Austin since June 22. The vehicles have been operated without a driver, but Tesla has placed safety monitors in the passenger’s seat as a precaution.

The safety monitors are responsible for performing any necessary interventions and maintaining a safe and comfortable cabin for riders as they experience Tesla’s first venture into the driverless ride-sharing space.

Last week, Tesla expanded its service area in Austin for the third time, expanding it from about 90 square miles to 170 square miles. The expansion included new territory, including the Austin-Bergstrom International Airport, Tesla’s Gigafactory Texas, and several freeways.

The freeway is an area that is uncharted territory for the Tesla Robotaxi program, and this fact alone encouraged Tesla to switch up its safety monitor positioning for the time being.

For now, they will be riding in the driver’s seat when routes require freeway travel:

This is sure to draw criticism from skeptics, but it is simply a step to keep things controlled and safe while the first Robotaxi drives take passengers on the highway with this version of the Full Self-Driving software.

This FSD version differs from the one that customers have in their own vehicles, but CEO Elon Musk has indicated something big is coming soon. FSD v14 is coming to vehicles in the near future, and Musk has said its performance is pretty incredible.

Tesla had its best monthly performance ever in Turkey in August, thanks to a drastic spike in sales.

Tesla saw an 86 percent bump in sales of the new Model Y in Turkey in August compared to July, dominating the market.

The performance was one of Tesla’s best in the market, and the company’s sales for the month accounted for half of all EV sales in Turkey for August, as it dominated and led BYD, which was the second-best-selling brand with just 1,639 units sold.

Tesla managed to sell 8,730 Model Y vehicles in Turkey, outpacing almost every competitor by a substantial margin. Only one brand sold better than Tesla in August in Turkey, and it was Renault.

Electric vehicles are, in some ways, more desirable than their gas counterparts in Turkey for several reasons. Most of the reasoning is financial.

First, EVs are subject to a lower Special Consumption Tax in Turkey. EVs can range from 25 percent to up to 170 percent, but this is less than the 70 to 220 percent rate that gas-powered vehicles can face. The tax is dependent on engine size.

Additionally, EVs are exempt from the annual Motor Vehicle Tax for the first ten years, providing consumers with a long-term ownership advantage. There are also credits that can amount to $30,000 in breaks, which makes them more accessible and brings down the cost of ownership.

Let’s not forget the other advantages that are felt regardless of country: cheaper fuel costs, reduced maintenance, and improved performance.

The base Model Y is the only configuration available in Turkey currently.

Tesla is upgrading airbag safety through a crazy software update, which will utilize the company’s vision-first approach to enable better protection in the event of an accident.

Over the years, Tesla has gained an incredible reputation for prioritizing safety in its vehicles, with crash test ratings at the forefront of its engineers’ minds.

This has led to Tesla gaining numerous five-star safety ratings and awards related to safety. It is not just a statistical thing, either. In the real world, we’ve seen Teslas demonstrate some impressive examples of crash safety.

Everything from that glass roof not caving in when a tree falls on it to a Model Y surviving a drive off a cliff has been recorded.

However, Tesla is always looking to improve safety, and unlike most companies, it does not need a physical hardware update to do so. It can enhance features such as crash response and airbag performance through Over-the-Air software updates, which download automatically to the vehicle.

In Tesla’s 2025.32 Software Update, the company is rolling out a Frontal Airbag System Enhancement, which aims to use Tesla Vision, the company’s camera-based approach to self-driving, to keep occupants safe.

The release notes state (via NotaTeslaApp):

“This upgrade builds upon your vehicle’s superior crash protection by now using Tesla Vision to help offer some of the most cutting-edge airbag performance in the event of a frontal crash. Building on top of regulatory and industry crash testing, this release enables front airbags to begin to inflate and restrain occupants earlier, in a way that only Tesla’s integrated systems are capable of doing, making your car safer over time.”

The use of cameras to predict a better time to restrain occupants with seatbelts and inflate airbags prior to a collision is a fantastic way to prevent injuries and limit harm done to those in the vehicle.

The feature is currently limited to the Model Y.
