Mini Electric

11.07.2019

The German automaker BMW has introduced a serial electric car Mini Electric (Mini Cooper SE). The novelty is based on the ICE version of the model, so the design, dimensions, interior design and other characteristics are almost identical (with a few exceptions). For example, the height of an electric car is only 18 mm higher, and the weight is only 145 kg more.

The three-door, front-wheel-drive Mini Electric received a BMW-designed electric motor with 135 kW (184 hp) and 270 Nm of torque. Acceleration from 0 to 60 km / h takes 3,9 seconds, from 0 to 100 km / h - 7,3 seconds, top speed is limited to 150 km / h.

The driver has four efficiency modes (Standard, Sport, GREEN and GREEN+) and two levels of recuperation settings that allow you to choose a driving mode in which just one accelerator pedal is enough to control the dynamics.

The T-shaped battery is integrated into the floor (it is located between the front and under the rear seats, which made it possible to save legroom), it is assembled from 12 modules with a total capacity of 32,6 kWh.

A full charge of the battery is enough to cover from 235 to 270 km (WLTP) depending on driving style and road conditions. The battery supports high-speed charging up to 50 kW, in this mode, 80% of the capacity is gained in 35 minutes. The charging connector is located above the rear right wheel.

Standard equipment includes LED headlights, 5,5-inch digital instrument cluster, dual-zone air conditioning, heat pump-based interior heating, electric parking brake, and 6,5-inch Connected Navigation (Connected Navigation package available as an option). Plus with 8,8-inch screen).

The Mini Electric will be assembled in November this year in the UK, at the same plant in Oxford where the ICE version is assembled. The cost of an electric car, taking into account benefits, starts at $30400, the first deliveries to customers will take place in early 2020.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

New Linear DC Regulators 28.03.2010

ON Semiconductor introduces the NCP1237, NCP1238, and NCP1288 fixed-frequency, current-controlled controllers for high-efficiency, compact AC/DC converters. Designed for use in laptops, LCDs, printers and other consumer electronics, the instruments offer a choice of operating frequencies and the ability to set one or two overcurrent thresholds.

The standard transducer has a built-in 65 kHz oscillator (100 and 133 kHz versions available on request). The patented Soft-Skip mode used in these microcircuits allows you to smoothly reduce the maximum current, reducing the risk of low-frequency noise. This allows you to save on additional components, simplifying the design of the device and transformer.

Combining this with current limiting, the new controllers provide a high level of efficiency at low load resistance by reducing the input power at idle.
