Did Tesla Buy Maxwell for Its Ultracapacitors or Higher-Density Batteries?

By ExtremeTech Posted On 20.2.2019

By Bill Howard, Tesla made headlines this month — actually, when doesn’t Tesla make headlines? — when the company bought battery-maker Maxwell for its ultracapacitor technology and its work on battery density. Analysts agreed Tesla was smart to pay in shares of Tesla stock, not cash, because Tesla has lots of stock on hand. Analysts are also divided on the prospects of ultracapacitors in the near term and Maxwell as an acquisition. But Maxwell is also a developer of other battery technology. It’s just that ultra-caps generate the most intense interest. (more…)

Structural Supercapacitors Prepare for Take-off

Energy-storage devices that perform multiple functions, such as powering a vehicle and letting it withstand mechanical loads, offer several potential benefits, as Natasha Shirshova explains
Consider an electric car. Whether your image is of a Nissan Leaf, a Tesla Model S or a BMW i3, such vehicles essentially consist of two main parts. There is an electrical part (the battery and the motor) and a structural part (the body of the car). The battery’s only job is to store and distribute electrical energy. Its structural function, as far as it has one, depends solely on the properties of its casing and is generally limited to protecting the battery itself. The car body, meanwhile, provides structural integrity but stores no electrical energy. In some circumstances, however, it may be possible (and indeed desirable) to combine these two aspects into a single material – one that can perform both structural and energy-storage functions.

Performance of AEC-Q200 rated power resistors for automotive use

By EDN Posted On 13.2.2019

Source: EDN article

by Bertram Schott & Adrian Michael.

Wirewound power resistors are usually rated with respect to continuous power, which can be insufficient for e-mobility applications. A typical application is the pre- and discharge of large capacitors, often referred to as “soft start.” In this case the pulse-handling capability of the resistor is also very important. This capability can be determined over a large range of pulse durations by combining theoretical basics with finite element simulations of the respective thermal performance. The results can be generalized so that changing customer specifications can quickly be evaluated and suitable resistors suggested. (more…)

Reliability Becomes The Top Concern In Automotive

By Semiconductor Engineering Posted On 12.2.2019

Source: Semiconductor Engineering article

by Ed Sperling and Susan Rambo. Extended lifetimes and advanced-node designs are driving new approaches, but not everything is going smoothly. Reliability is emerging as the top priority across the hottest growth markets for semiconductors, including automotive, industrial and cloud-based computing. But instead of replacing chips every two to four years, some of those devices are expected to survive for up to 20 years, even with higher usage in sometimes extreme environmental conditions.
