Smart TDK system for wireless charging of electric vehicles

12.10.2014

At CEATEC 2014 in Japan, TDK is demonstrating the latest advances in the development of wireless charging systems for electric and hybrid vehicles.

In April, TDK licensed a number of WiTricity technologies for use in wireless charging pads. Recall that the effect of magnetic resonance is involved in the WiTricity system. It uses electromagnetic waves in the range from 300 kHz to 20 MHz (considered safe for health). Theoretically, it is possible to transfer up to 25 kW of energy.

The TDK system uses a special WiTricity pad that can be built into the floor of a garage or, say, into an asphalt pavement in a parking space. Moreover, in the future, as conceived by the developers, such modules can be built directly into the roadway to charge electric vehicles in motion. The latter to receive energy must have a special receiver in the bottom of the body.
Currently, the TDK complex allows the transmission of 3,3 kW of energy. By 2018-2019 this figure is planned to be increased to 6,6 kW.

The TDK platform is expected to be endowed with "smart" features. For example, a motorist will be able to receive notifications through the dashboard or on-board computer about the presence of wireless charging sites nearby. In addition, the car will be able to park itself exactly above the power source, ensuring maximum efficiency of the charging process.

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, ... >>

Intent Predictive Headphones 06.05.2021

The idea for the Enten headphones, which can read a person's intentions, was brought to life by Neurable under the direction of Dr. Ramses Alkaide. While still a student, he thought about developing technologies that could directly interact with the human brain. Initially, the techniques were interesting in the field of prosthetics. However, over time, the scientist realized that the application of technology could be much wider.

The result of the work was a lot of interesting and useful devices. Neurable has announced the pre-order of the first pair of Enten headphones with BCI technology. Their work is based on the fact that the user has only a couple of hours of daily high productivity.

The device suggests the user the best time to take a break in order to maintain high performance throughout the day. Also, the headphones have active elements to turn off notifications when the user is busy.

Unlike conventional headphones, the new ones are made of fabric to make them easier to use. In fact, the new device fully performs the functions of the usual headphones and at the same time allows the user to understand how his brain works.
