What makes the Tesla 100 kWh battery so different?

Published

on

Tesla’s 100 kWh battery has rocked the automotive world. It’s 11% increase in capacity over its previous flagship batter has drawn global attention from media because it allows Tesla to shatter two long standing records. First, it makes the new Model S P100D with Ludicrous the first production electric car with more than 300 miles of range — 315 miles. Second, it means the car has become the world’s fastest accelerating mass production car capable of rocketing 0-60 mph in a blistering 2.5 seconds. For context, the limited-run Porsche 918 Spyder and Ferrari’s LaFerrari are the next closest rivals in terms of acceleration from a standstill, though both of  these hypercars are now out of production and each sold for more than $1,000,000.

For daily driving, acceleration from a standing start is a fairly irrelevant statistic. But it’s the kind of thing that makes people notice and that’s the attention Elon Musk craves for his cars. In his mind, the more people get excited about electric cars, the more people will buy one and the sooner the electric car revolution will come to fruition. Besides, the car’s ferocious mid-range acceleration is something real drivers can appreciate when passing slower vehicles — which means every other car on the road.

Tesla, as usual, has not revealed many details about the new 100 kWh battery except to say it is close to the theoretical maximum power that can be squeezed into the space available in the Model S and Model X battery chassis. Tesla CTO JB Straubel did say during the P100D press conference that the new battery required a “complete redo” of the internal cooling system. What does that mean?

The folks at LiveScience via EVAnnex think they have an explanation. Previously, Tesla employed a ribbon filled with glycol to control the heat of the individual battery cells. Tesla has abandoned that system entirely and replaced it with thin aluminum fins between the battery cells that conduct heat away and transfer it to a cold plate below. The theory is the aluminum fins are thinner than the glycol filled cooling ribbon, allowing more cells to be mounted in the same physical space.

Straubel hinted that the new improvements are vital to making the upcoming Model 3 meet its range, power, and price targets. That may be even more important that making the Model S the fastest electric car with the most range in the history of the world. Read more at EVAnnex.

SpaceX aces Starship test flight 10 with successful payload deployment

The mission began at 6:30 p.m. local time in Starbase, Texas, when the launch of Starship initiated. After about eight minutes, stage separation was completed, and the Super Heavy Booster headed back down to Earth for a planned splashdown in the Indian Ocean:

SpaceX aced its tenth Starship test flight on Tuesday night after multiple delays pushed the mission back to this evening. Originally scheduled for Sunday night, SpaceX had two delays push the flight back to Tuesday, which ultimately provided ideal conditions for a launch attempt.

The tenth test flight of Starship had several objectives, including a successful splashdown of the booster in the Gulf of America, the deployment of eight Starlink simulation modules from the PEZ dispenser, and a splashdown of the ship in the Indian Ocean.

SpaceX successfully achieved all three of these objectives, making it one of the most successful test flights in the Starship program. There was no attempt to catch the booster this evening, as the company had been transparent about it ahead of the launch.

Starship was then the main focus of the rest of the broadcast as it completed its ascent burn and coasted through space, providing viewers with spectacular views as the mission headed toward new territory, including the deployment of Starlink simulators. This would be the first time SpaceX would attempt a payload deployment.

The deployment works like a PEZ dispenser, as the simulators were stacked on top of one another and would exit through a small slit one at a time.

This occurred roughly 20 minutes into the mission:

An hour and six minutes into the flight, Starship reached its final destination, which was the Indian Ocean. A successful splashdown would bring closure to Starship’s tenth test flight, marking the fifth time a test flight in the program’s history did not end with vehicle loss.

It was also the first of four test flights this year that will end with Starship being recovered.

SpaceX is expected to launch Starship again in approximately eight weeks, pending the collection of data and other key metrics from this flight.

WATCH: SpaceX attempts Starship’s tenth test flight after two delays

This evening, SpaceX has already stated that conditions appear to be approximately 45 percent favorable for launch. This is ten percent less than last night, when the mission was eventually scrapped around 7 p.m. local time.

SpaceX is set to launch Starship tonight, provided the weather cooperates and everything with the ship goes smoothly.

This is SpaceX’s third attempt to launch Starship for its tenth test flight, with Sunday’s and Monday’s attempts both being scrapped due to a leak and unfavorable weather conditions on the respective days.

Propellant load of the upper stage and Super Heavy booster is already underway, and the launch is expected to occur at 6:30 p.m. in Starbase, Texas.

Tesla one-ups Waymo once again with latest Robotaxi expansion in Austin

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.

Tesla’s expansion of the Robotaxi geofence on Tuesday morning was a one-up on Waymo once again, as the automaker’s service area growth helps eclipse its rival in an intense back-and-forth.

A lot of conversation has been made about Tesla’s rivalry with Waymo in terms of the capabilities of its driverless ride-sharing service in Austin, Texas.

The two companies have sparred with one another, answering each other’s expansion, and continuing to compete, all to the benefit of consumers in the region.

Tesla expanded the geofence of Robotaxi once again this morning, and it is another growth that catapults it past Waymo’s service area in Austin — this time by a considerable margin.

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.

On July 14, Tesla officially overtook Waymo in terms of service area in Austin. But just a few days later, Waymo had responded with a bold statement, expanding from 37 square miles to 90 square miles.

Sarfraz Maredia, Global Head of Autonomous Mobility & Delivery at Uber, said the move “unlock[ed] another key milestone in Austin as our operating territory with Waymo expands from 37 to 90 square miles, which means that even more riders can experience Waymo’s fully autonomous vehicles through the Uber app.”

Tesla did not respond immediately, but it took its time with validation vehicle testing in the Austin suburbs, as we reported yesterday:

Tesla looks to expand Robotaxi geofence once again with testing in new area

Today’s expansion is perhaps the biggest step Tesla has taken in its efforts to continue to grow its Robotaxi platform. This is not only because the company has significantly expanded the size of the geofence, but also because it has ventured into suburban areas and even included Gigafactory Texas in its service area.

Waymo could come up with another timely response as it did when Tesla expanded in late July. We’ll wait to see what it comes up with, as this awesome competition between the two companies is accelerating innovation.
