Electric car charges in 30 minutes

04.05.2013

Siemens and Volvo have teamed up to find a solution to the problem of long battery charging times in electric vehicles. They have already developed a number of related technologies, thanks to one of which it takes a maximum of an hour and a half to replenish the charge.

Everything is implemented in the form of a special 22-kilowatt charger, which is currently being tested on the Volvo C30 Electric electric car. This, we note, is the first on-board charger in the world that operates from a 3-phase current source. By connecting to the appropriate outlet, this charger will accumulate energy in the battery in an hour and a half, which is enough for 165 kilometers. And for an 80 percent charge, just half an hour is enough.

This is indeed a significant breakthrough as 99% of electric vehicles have to be tethered to a power outlet for 8 hours in order for their battery to be fully charged. The German company Siemens, which helped Volvo develop a new charger, at the same time upgraded the electric motor of the C30 Electric car - now it produces 120 hp. power at a torque of 250 Nm. The maximum speed of the car is 125 km / h, and acceleration to hundreds takes only 5,9 seconds.

Manufacturers installed the new charger directly under the hood, bringing the plug hole into the radiator grille and, thus, fitting it as harmoniously as possible into the design of a production car. The compact Volvo C30 Electric hatchback, despite having a 24-kilowatt battery pack, has a fairly spacious interior. Together with the battery, the mass of which was 330 kilograms, the car weighs 1725 kg. Its cost after completion of Siemens is not specified.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

flu breath 21.01.2018

Influenza spreads by airborne droplets - there are viral particles in aerosol droplets that fly out of the patient's mouth, and by inhaling them, we become infected. Where do these microdroplets with a viral filling come from? Obviously, when the patient sneezes and coughs; we instinctively try to move away from such people. However, in fact, coughing and sneezing is not at all necessary: viruses scatter from the patient, even when he is just breathing.

Researchers at the University of Maryland followed nearly XNUMX people with the flu who had symptoms either recently, a day ago, or two days ago. Patients talked, coughed, sneezed, or simply breathed calmly, and the air that came out of their mouths for half an hour was collected and analyzed for viruses; moreover, the presence of the virus was assessed both by its RNA and by whole virus particles.

In about half of the cases when the air sample was taken without coughing and sneezing, the aerosol particles contained a sufficient amount of viral RNA, and most of the "respiratory" aerosols contained whole viral particles. That is, as mentioned above, a person with the flu spreads the virus around him simply by breathing, without any coughing or sneezing. Moreover, the authors argue that when sneezing, the virus does not appear in the air as much as one might expect, that is, sneezing, compared to normal breathing, does not fill the surrounding air with the virus very much.

The new data will help create better mathematical models to describe the spread of influenza (and likely other airborne viruses); such models will enable epidemiologists to more accurately assess the likelihood and severity of seasonal epidemics.

As for more everyday things, even if a person manages not to sneeze or cough, especially in the first days of illness, this is not at all a reason to leave the house: even just breathing in a crowded place, he can infect a bunch of people.
