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. [...]

Semiconductor Record Fab Spending 2018

2018-05-14T10:33:13+00:00

Good News for Materials Scientists - Semiconductor Record Spending Fab spending reports show unprecedented high semiconductor equipment sales are being driven by a handful of well-known companies, and also by several new Chinese companies entering the semiconductor marketplace. An increase in overall fab spending (greenfield construction and equipment together) of 54 percent year-over-year (YoY) in China is expected.  Total spending in China rose from $3.5 billion in 2016, to $5.4 billion in 2017, and then is anticipated to be $8.6 billion in 2018, another 60 percent year-over-year (YoY). The demand for Materials Scientists to develop manufacturing processes and engineers to install and maintain the equipment will be huge as well . Fab Spending is Beyond Silicon Valley China-based companies [...]

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 [...]

A Licensed Mechanical Engineer at Glew Engineering Consulting was asked by a company in Southern California to provide a Professional Engineer (P.E.) review of body modifications that they made to a theme park owned 1983 Sport Utility Vehicle (SUV) that they had converted to an electric vehicle. Figure 1. A Mechanical Engineer Analyzed the Front of Custom Sport Utility Vehicle  Licensed Mechanical Engineer Reviews a Modified Electric Vehicle The client had already designed and built a vehicle, so Glew Engineering analyzed an “as built” vehicle.  The company hoped to repurpose a float/SUV that they had used previously in parades.  Our client was requested by the theme park to repurpose the SUV, and perform cosmetic alterations [...]
