2024 Tesla Model Y Update: All You Need to Know About Redesign, Powertrain, and Innovations

What specific changes can we expect in the exterior and interior of the 2024 Tesla Model Y Juniper? When exactly will the Model Y refresh be released? Will there be any improvements in the battery and technology of the Model Y?

As the electric vehicle market continues to thrive, Tesla remains at the top of the EV ladder with its models staying in the top selling charts. Among its impressive lineup, the Model Y stands out as a tough rival shaping the whole EV market in its favor.

With the upcoming release of the 2024 Tesla Model Y Project Juniper and Model 3 Project Highland, as we discussed in our recent posts, Tesla is aiming to redefine the electric SUV segment even further. This highly anticipated refresh promises exciting changes to both the interior and exterior of the popular Model Y.

Low-cost additive turns concrete slabs into super-fast energy storage

MIT researchers have discovered that when you mix cement and carbon black with water, the resulting concrete self-assembles into an energy-storing supercapacitor that can put out enough juice to power a home or fast-charge electric cars.

We’ve written before about the idea of using concrete for energy storage – back in 2021, a team from the Chalmers University of Technology showed how useful amounts of electrical energy could be stored in concrete poured around carbon fiber mesh electrodes, with mixed-in carbon fibers to add conductivity.

MIT’s discovery appears to take things to the next level, since it does away with the need to lay mesh electrodes into the concrete, and instead allows the carbon black to form its own connected electrode structures as part of the curing process.

Engineers create an energy-storing supercapacitor from ancient materials

Two of humanity’s most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for a novel, low-cost energy storage system, according to a new study. The technology could facilitate the use of renewable energy sources such as solar, wind, and tidal power by allowing energy networks to remain stable despite fluctuations in renewable energy supply.

The two materials, the researchers found, can be combined with water to make a supercapacitor—an alternative to batteries—that could provide storage of electrical .

As an example, the MIT researchers who developed the system say that their supercapacitor could eventually be incorporated into the concrete foundation of a house, where it could store a full day’s worth of energy while adding little (or no) to the cost of the foundation and still providing the needed structural strength. The researchers also envision a concrete roadway that could provide contactless recharging for as they travel over that road.

Rumors are swirling about a new Tesla battery that could give its cars 100 miles of charge in just 5 minutes

Electric vehicle manufacturer Tesla is the frequent subject of rumors and speculation, all of which must be taken with a grain of salt. But if the newest batch of rumors is to be believed, Tesla is currently looking into an “extreme fast charging” technology developed by Israeli startup StoreDot, per Inside EVs.

The news comes via an article in USA Today that, as Inside EVs noted, “doesn’t cite any sources.” The USA Today article in question was written by a contributor and contained a disclaimer at the bottom reading, “Members of the editorial and news staff of the USA TODAY Network were not involved in the creation of this content.”

If the report is to be believed, Tesla’s interest in StoreDot could mean shorter charging times for Teslas, as the company claims to have developed batteries that can charge 100 miles of driving range in just five minutes, per Inside EVs.

News About Advances in Sodium-Ion and Solid-State Batteries

Sodium-ion (Na-ion) batteries and solid-state batteries have both been in the news recently. Why? Because the need for battery storage is growing rapidly as the global economy seeks carbon-based energy alternatives in pursuit of the goal to achieve net-zero emissions by the mid-century.

Na-ion Battery News

In April I wrote about BYD, a Chinese electric vehicle (EV) manufacturer, that is using sodium-ion (Na-ion) battery packs instead of lithium-ion (Li-ion) in some of its models. In its latest report, IDTechEx, out of Cambridge in the United Kingdom, states that although Na-ion batteries are not the answer to all battery-power applications, they do provide a complimentary addition to battery packs used not just in EVs but also for backup power within utilities and factories.

Why Are Tesla Owners Selling Their Model 3s? Here’s What One Survey Revealed About Their Perception Of Elon Musk

Since launching in July 2017, the Model 3 from Tesla Inc TSLA has been one of the bestselling electric vehicles of all time.

A recent Bloomberg survey reveals how Model 3 owners have felt about the company over time — and Tesla CEO Elon Musk might not love the results.

What Happened: The Model 3 and Model Y continue to be Tesla’s bestselling models and big reasons why the company has dominated the market share for electric vehicles around the world.

Tesla exaggerated range figures, set up secret team to divert customer complaints

The range has been a top concern for potential buyers transitioning from internal combustion vehicles to electric ones. In 2008, when EVs were still a rare new concept, Tesla promised a 200-mile (320 km) range on a single charge on its Roadster, a model it soon discontinued. Its second offering, Model S, promised a higher range of 249 miles (401 km) in 2012.

Eco-friendly proton battery offers affordable energy storage

RMIT University’s new proton battery could revolutionize energy storage, offering a safe, affordable, eco-friendly alternative to lithium-ion batteries.

The latest ‘proton battery’ developed by RMIT University holds the potential to revolutionize power supply for homes, vehicles, and devices without the disposal-related environmental challenges posed by lithium-ion batteries.

The battery works by using a carbon electrode to store hydrogen that has been separated from water, functioning like a hydrogen fuel cell to generate electricity.

Scientists invent accurate AI-powered heat vision for driving at night

The technology can also be used in fog and smoke, aiding firefighters.

This is according to a report by PopSci published on Wednesday.

Researchers at Purdue University and Los Alamos National Laboratory have joined forces to engineer something they call “heat-assisted detection and ranging,” or HADAR, which consists of a completely new camera imaging system based on AI interpretations of heat signatures. The technology could soon allow vehicles and robots to see at night time.

A once muddy, unclear tech

We have all seen movies where agents use thermal imaging to see their surroundings in the dark, but in reality, this technology is far from practical because thermal radiation particles diffuse into their nearby environments. This means that trying to image them becomes a complicated, muddy, and unclear process.

Molecular highway for electrons in organic light-emitting diodes

Organic light-emitting diodes (OLEDs) are now widely used. For use in displays, blue OLEDs are additionally required to supplement the primary colors red and green. Especially in blue OLEDs, impurities give rise to strong electrical losses, which could be partly circumvented by using highly complex and expensive device layouts. A team from the Max Planck Institute for Polymer Research has now developed a new material concept that potentially allows efficient blue OLEDs with a strongly simplified structure.

From televisions to smartphones: (OLEDs) are nowadays finding their way into many devices that we use every day. To display an image, they are needed in the three primary colors red, green and blue. In particular, for are still difficult to manufacture because blue light—physically spoken—has a , which makes the development of materials difficult.

Especially the presence of minute quantities of impurities in the material that cannot be removed plays a decisive role in the performance of these materials. These impurities— , for example—form obstacles for electrons to move inside the diode and participate in the light-generation process. When an electron is captured by such an obstacle, its energy is not converted into light but into heat. This problem, known as “charge trapping”, occurs primarily in blue OLEDs and significantly reduces their efficiency.
