Warner Electric’s new brake design extends EV range / IVT
]
KINGSTON, Mass. – Warner Electric, a leading brand of Altra Industrial
Motion Corp., has developed a new electromagnetic brake that greatly reduces
power consumption during operation.
The SSPB pulse brake is highly efficient and well suited to electric vehicle
applications – increasing range while controlling soft stops proficiently.
Power saving is an important consideration in most applications, but none
more so than the electric vehicle market. OEMs are battling to maximize the
effective range of electric vehicles to gain an operational and market
advantage. Increasing efficiency and reducing visits to the charge point are
of paramount importance.
The longer the range, the more productive, practical and cost-effective the
vehicle becomes. With finite battery power to work with, focus is now
turning to reducing the power consumption of auxiliary vehicle systems to
further improve vehicle range.
Warner Electric has leveraged its extensive experience as a global
electromagnetic brake OEM to deliver an efficient braking solution to meet
these requirements. The SSPB is designed to preserve battery life via its
reduced power consumption. This Bi-stable brake relies on pulses of current
to operate the brake, offering a distinct advantage over other devices.
Usually, electromagnetic brakes require a constant power supply to be held
open, therefore the brake is consuming energy whenever it isn’t controlling
a stop. The SSPB brake reduces this energy consumption by relying on a
single, short pulse of current to open or close, eliminating the need for a
constant power supply. One pulse will be sent to close the brake and come to
a stop, another to open them and start moving.
As a result of this efficiency, the vehicle’s finite amount of stored energy
can be used for other functions. This can serve to greatly increase range,
improving the viability of electric vehicles in many new industries or
environments. The power saving features benefit both pure electric vehicles
and hybrid-electric systems.

Costa Rica has more than 100 electric car charging stations within its
national territory, according to First Lady Claudia Dobles, making the
Central American country the first in the region with a nationwide charging
network.
The news was announced this week during a forum to provide updates on Costa
Rica’s National Decarbonization Plan, which aims to decarbonize the
country’s economy by 2050.
The website PlugShare, which identifies EV charging stations worldwide,
lists at least 120 locations in Costa Rica — the majority clustered around
the Greater Metropolitan Area (GAM), including San José [.cr].
When the National Decarbonization Plan was inaugurated last year,
modernizing the country’s transportation infrastructure was listed as a
pillar of the initiative.
“In the first year of the National Decarbonization Plan, we have managed to
convert goals into actions, to modernize our transport and guarantee the
population mobility options in a safe and sustainable way,” Dobles said.
Electric vehicles would help Costa Rica rely more fully on green energy; the
country has generated more than 98% of its power through renewable resources

] over the last five years.
Still, while the Costa Rican Electricity Institute (ICE) and Correos de
Costa Rica operate fleets of electric vehicles, the government says fewer
than 400 such cars entered the country in 2019. Costa Rica incentivizes
electric vehicle ownership with tax breaks.
In addition to electric vehicles, the National Decarbonization Plan also
includes electric railway projects. An electric passenger train, which would
be the backbone of a modern transportation system through the Greater
Metropolitan Area, will soon reach the Legislative Assembly for debate,
according to Dobles.
An electric freight train in Limón and the rebuilding of the Pacific
railroad remain in feasibility stages.

[EVDL] Design News: Lithium-Sulfur Batteries
World's Most Efficient Lithium-Sulfur Battery Tested By Australian Scientists Researchers eye the design — which can power a smartphone for five days straight — for grid-scale energy and EVs, among other applications. By: [Elizabeth Montalbano](https://www.designnews.com/author/elizabeth-montalbano) [Electronics & Test](https://www.designnews.com/electronics-test) [Battery/Energy Storage](https://www.designnews.com/batteryenergy-storage) February 11, 2020 Lithium-ion batteries are still the norm for devices from smartphones to electric vehicles. However, the design is limited in terms of energy storage and efficiency, which is why researchers are seeking other chemistries for energy-storage cells. Monash University Associate Professor Matthew Hill, Dr. Mahdokht Shaibani and Professor Mainak Majumder with a lithium-sulfur battery design they hope can be used to power the energy grid and electric vehicles in the future. (Image source: Monash University). One of those designs is a lithium-sulfur battery, which theoretically can hold a charge capacity of six times that of lithium-ion batteries. Researchers at Monash University in Australia [have developed](https://www.monash.edu/news/articles/supercharging-tomorrow-australia-first-to-test-new-lithium-batteries) the most efficient battery of this kind, which they say is capable of powering a smartphone for five continuous days. Lithium-sulfur not only has an advantage over lithium-ion in capacity, it also has other environmental and ethical benefits, said Matthew Hill, an associate professor at the university who worked on the research. “Lithium-sulfur batteries use commonly available ingredients, in comparison to the hazardous cobalt often used in lithium ion batteries, which is often mined by children in the Congo,” he told Design News. Hill and his team—which includes the leader of the research, Mahdokht Shibani from the university’s [Department of Mechanical and Aerospace Engineering](https://www.monash.edu/engineering/departments/mechanical)—aim to commercialize the lithium-sulfur battery they’ve developed, with global partners already showing interest in manufacturing and using the design. In addition to already filing a patent for their manufacturing process, Germah research-and-development partners Fraunhofer Institute for Material and Beam Technology also have developed prototype cells of the design, Monash researchers said. Scientists plan to test the batteries in automobiles and solar grids in Australia in 2020. Creating A Better Cathode While lithium-sulfur theoretically can outperform lithium-ion batteries, there have been challenges to designing cells that live up to this potential due to the tendency for sulfur cathodes to drop in capacity or performance with higher stress loads. To overcome this limitations, the Monash team engineered a method that created bonds between particles to accommodate stress and deliver a level of stability that’s unprecedented for this type of battery. “The sulfur cathode shrinks and swells when it stores and releases all this charge, our design allows it to do this while staying together structurally,” said Hill. “This means the tantalizing high capacity can be used over many charge and discharge cycles. We have been able to show much longer cycling lifetimes under relevant conditions for use in the real world.” Researchers published a [paper](https://advances.sciencemag.org/content/6/1/eaay2757) on their work in the journal Science Advances. Once tests are complete and successful, the team hopes the battery will be mass produced and used for various applications, including “grid-scale renewable energy storage, electric vehicles, and longer lasting devices,” Hill said. --- Elizabeth Montalbano is a freelance writer who has written about technology and culture for more than 20 years.
