Electric Vehicle Batteries: Recycled

2018-07-18T14:04:45+00:00

  Material Scientist Ponder What to Do With Used EV Batteries  As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025.  This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements.  The price of cobalt has already risen by more than 80 per cent in 2018.   Most expert Material Scientists agree that a replacement hybrid car battery can range from $1,000 to more than $6,000.  The [...]

Engineering Advances: Degradation and Saving Electric Vehicle Batteries

2018-07-10T15:47:30+00:00

Degradation of EV Lithium Batteries  Battery degradation in Electric Vehicles (See Figure 1. to Right) leads to capacity fade, thereby shortening the vehicle’s possible range.  Patterns are beginning to emerge and provide valuable insight into EV battery capacity and lifetime.  Most drivers are retaining over 90% of original capacity Range Anxiety Some cars have a range of only 106 miles, equivalent to just over three times the average daily drive in the US. New Electric Vehicles are expected to have a range of up to 235 miles, a 220% increase, therefore, range is constantly improving to address consumer concerns. Charging an EV takes time, and unless you have fast in-home charging infrastructure or public charging infrastructure it will remain a barrier. [...]

NAND Flash – 11 Myths Still Floating Around

2018-06-27T16:21:57+00:00

Think You Know NAND Flash?  NAND flash has become the de facto memory standard in the years since Toshiba first introduced it almost three decades ago. However, many misconceptions remain to this day about its use. A wide variety of NAND flash-memory products are available, all with significantly different features and capabilities.    All NAND flash has the same interface. NAND flash, introduced by Toshiba more than 20 years ago, is available in both the asynchronous and toggle-mode interfaces. The original asynchronous interface is found mostly in lower-density devices (<32 Gb), while high-density NAND flash (≥64 Gb) is typically used in the toggle-mode interface.( http://glewengineering.com/tester-prober-interfaces-direct-probe-part-1/  UFS memory is primarily just for smartphones. Universal Flash Storage (UFS), while smartphones [...]

Semiconductor Worldwide: Samsung Takes Over

2018-06-22T11:44:20+00:00

Samsung topples Intel as top dog semiconductor market share  Gartner beancounters say price rises driven by memory shortages propelled Samsung into the lead based on semiconductor vendor revenue, vaulting past Intel and its CPUs. The largest memory supplier, Samsung Electronics, gained the most semiconductor market share and took the No. 1 position from Intel – the first time Intel has been toppled since 1992. Memory accounted for more than two-thirds of all semiconductor revenue growth in 2017, and became the largest semiconductor category.  DRAM prices rose 44 per cent from 2016 to 2017, and NAND flash prices went up 17 per cent year-over-year for the first time. (See Figure Below)   A Gartner table provides the numeric nitty-gritty [...]

Licensed Mechanical Engineers Design Zoo Habitats

2018-04-06T13:48:23+00:00

Licensed Mechanical Engineers Design Zoo Habitats Licensed Mechanical Engineers with Innovative Ideas Licensed Mechanical Engineers design habitats for Zoo Animals (see: Licensed Mechanical Engineers) accommodating all animals large and small.  Zoo care is a booming industry since the past decade.   Mechanical Engineers with innovative ideas can create sanctuaries for wildlife conservation.  Architects design the Facility Aesthetics of the Zoo.  Engineers keep the animals and public safe, and design technical aspects of the zoo enclosures.  Licensed Mechanical Engineers build habitats for animals using the most updated technical information available. Engineers ensure that the animal is content and cannot escape from its new habitat. Guests have a viewing area without encroaching the animals' personal space.  Mechanical Engineers need information such as how [...]
