Qualcomm Quick Charge 5

09.08.2020

Qualcomm has created a fast charger for smartphones Quick Charge 5.

The Quick Charge 5 standard offers to charge a smartphone battery from zero to 50 percent in five minutes. The company estimates that if the charge level is less than 50 percent, then it will increase by about one percent every six seconds. Qualcomm is calling the new charging protocol "the world's fastest commercial smartphone solution."

The company's engineers tested the new standard on devices with a 4500 milliamp-hour dual-cell battery. When charging with a power of 100 watts, the load is distributed evenly on both battery cells, approximately 50 watts each.

Compared to Quick Charge 4, the new standard is 70 percent more efficient and achieves a reduction in heating temperature when charging by about ten degrees.

The new standard supports the USB Power Delivery protocol, that is, it can be used not only when charging smartphones, but also computers. The first devices with Quick Charge 5 support should be available in the third quarter of 2020.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Compact medical power supplies Mean Well RPS-400 03.03.2017

Mean Well has developed a series of small size 400W power supplies (with external fan) for medical applications. The new RPS-400 series has a footprint of only 3"x5" and is available in the following modifications: open, in a casing (at the end of the name -C symbol), with a fan installed on top (-TF) and with a fan installed on the side of the output connector (-SF).

At the moment, among the power supplies of the RPS family, you can optimally select the required unit in a wide power range from 30 to 400 W (RPS-30/45/60/65/75/120/160/200/300/400). The new power supplies meet medical standards IEC60601-1 (Version 3), ANSI/AAMI ES60601-1 and TUV EN60601-1; have a protection level of 2 x MOPP, low leakage current (less than 250 µA) and can be used in devices that come into contact with the patient's body.

The RPS-400 features low standby power consumption (less than 0,5W), high efficiency (96% efficiency typ.); there is a power correction stage. The power supplies meet the EMC requirements of class B when connected with earth and class A when connected without earth.
