Will Apple Go All-In On Car Batteries?

A year and a half ago, Apple Inc applied for eight patents related to car batteries. Recently, it has added a slew of engineers, just one of whom had already filed for 17 in his former career, according to a Thomson Reuters.

The recent spate of hires and patent filings shows that Apple is fast building its industrial lithium-ion battery capabilities, adding to evidence the iPhone maker may be developing a car.

Quiet, clean electric cars are viewed in Silicon Valley and elsewhere as a promising technology for the future, but high costs and “range anxiety”, the concern that batteries will run out of power and cannot be recharged quickly, remain obstacles. Those challenges could also be seen as opportunities to find solutions to take the technology mainstream.

The number of auto-related patents filed by Apple, Google Inc, Korea’s Samsung, electric carmaker Tesla Motors Inc and ride-sharing startup Uber tripled from 2011 to 2014, according to an analysis by Thomson Reuters IP & Science of public patent filings.

Apple has filed far fewer of these patents than rivals, perhaps adding impetus to its recent hiring binge as it seeks to get up to speed in battery technologies and other car-building related expertise.

As of 18 months ago, Apple had filed for 290 such patents. By contrast, Samsung, which has been providing electric vehicle batteries for some years, had close to 900 filings involving auto battery technology alone.

The U.S. government makes patent applications public only after 18 months, so the figures do not reflect any patents filed in 2014.

Earlier this month, battery maker A123 Systems sued Apple for poaching five top engineers. A search of LinkedIn profiles indicates Apple has hired at least another seven A123 employees and at least 18 employees from Tesla since 2012.

The former A123 employees have expertise primarily in battery cell design, materials development and manufacturing engineering, according to the LinkedIn profiles and an analysis of patent applications.

A123, which filed for bankruptcy in 2012 but has since reorganized, supplied batteries for Fisker Automotive’s now-discontinued hybrid electric car.

“Looking at the people Apple is hiring from A123 and their backgrounds, it is hard not to assume they’re working on an electric car,” said Tom Gage, Chief Executive of EV Grid and a longtime expert in batteries and battery technology.

Apple is building its own battery division, according to the A123 lawsuit. Apple did not immediately respond to a request for comment.

MIT Develops Inflatable Antenna

Satellites the size of shoe boxes, which are expected to one day allow researchers to explore space more efficiently, will soon have greater range.

MIT researchers have built and tested an inflatable antenna that can fold into such a satellite, then inflate in orbit to enable long range communications — from seven times the distance possible today.

The technology will let the small satellites, called CubeSats, move further into space and send valuable information to scientists back on earth.

“With this antenna, you could transmit from the moon, and even farther than that,” said Alessandra Babuscia, a researcher on the inflatable antenna team at MIT, in a statement. “This antenna is one of the cheapest and most economical solutions to the problem of communication. But all this research builds a set of options to allow the spacecraft … to fly in deep space.”

The MIT effort comes as engineers at the University of Michigan work on ways to propel such small spacecraft into interplanetary space. The team is building a plasma thruster that could fit in a 10-centimeter space and push a small satellite-bearing spacecraft into deep space.

The university researchers using superheated plasma that would push through a magnetic field to propel a CubeSat.

The MIT researchers are seeking to solve the communications problems and enable far-afield CubeSats to send data to and receive instructions from Earth.

The CubeSat devices cannot support radio dishes that are used today to let spacecraft communicate when far from Earth’s orbit.

The inflatable antennas significantly amplifies radio signals, allowing a CubeSat to transmit data back to Earth at a higher rate, according to the university.

MIT engineers have built two prototype antennae, each a meter wide, out of Mylar, which is a polyester film known for its strength and use as an electric insulator. One antenna was a cone shape, while the other looks more like a cylinder when inflated. Each fits into a 10-cubic-centimeter space within a CubeSat.

Each prototype contains a few grams of benzoic acid, which can be converted to a gas to inflate the antenna, MIT noted.

In testing, the cylindrical antenna performed “slightly better” than the cone shaped device, transmitting data 10 times faster, and seven times farther than existing CubeSat antennae.
