FedEx and Chanje to develop electric vehicle charging infrastructure

April 24, 2020 by Mai Tao Leave a Comment

FedEx has now started on the “next phase” of its electric vehicle rollout after initially launching construction on electronic direct current charging stations back in January.

One of the biggest logistics companies in the US, Federal Express has been using all-electric vehicles as part of its pickup-and-delivery fleet for more than 10 years.

Through a new agreement with Chanje Energy, the company plans to electrify 42 FedEx stations in California, making it one of the largest deployments of integrated charging infrastructure by a single commercial fleet to date.

How do DC/DC converters work in hybrid and electric cars?

July 4, 2019 by Liv

Within every electric vehicle is a battery that outputs a certain voltage.

Given that this voltage might not be appropriate for the various devices being driven, we need to install another device along the signal path.

This device is known as a DC/DC converter, and without it, the modern electric car wouldn’t be possible. [Read more…] about How do DC/DC converters work in hybrid and electric cars?

ABB to supply high power charging for new era of e-mobility in Scandinavia

June 3, 2019 by Anna

ABB is to equip new electric vehicle (EV) charging stations across Denmark, Norway and Swede, starting with a first station now open in Fredericia, Denmark.

The station, a joint venture with E.ON Drive & Clever, and is part of ABB’s plan to roll out 48 high-power charging stations across the motorways of Denmark, Norway and Sweden.

The pilot station, which will be one of eight stations to launch in Denmark by the end of 2020, features ABB Ability-enabled high-power chargers, which are capable of adding up to 200 km of range in just eight minutes.

The advantages of automation in medical diagnostics

June 17, 2017 by Sam Francis

Technology in the fields of life sciences and medicine is constantly evolving. New manufacturing techniques have made it possible to make more effective therapies, and advances in research have led to more cost-effective solutions to conditions that were once considered too expensive to treat.

One of the most interesting aspects of the evolution of medical technology is the constantly increasing involvement of automation in various medical operations, particularly in diagnostics.

Back then, essential diagnostic procedures relied on manual procedures. While conventional methods were successful to a certain degree, they are hampered by certain limitations.

For instance, manual testing of specimens is slow and prone to mistakes caused by poor human judgment. Automation helps get rid of these limitations to achieve more accurate results in less time. [Read more…] about The advantages of automation in medical diagnostics

Kollmorgen expands its AKM servo motor series

May 13, 2017 by Sam Francis

Kollmorgen says its new servo motor has energy efficiency, durability, power density, overload capability, and – crucially – is extra low voltage.

The new AKM DC servo motor low voltage with its 48-volt design was originally intended as a customer-specific solution for special areas of use.

Kollmorgen, a specialist in servo-drive technology and motion control will now offer this as a standard add-on to the AKM series, and thus as a new series product. [Read more…] about Kollmorgen expands its AKM servo motor series

Electric power: Clean energy infrastructure driving switch from AC to DC

January 21, 2017 by Mark Allinson

Nikola Tesla was a famous scientist who developed alternating current, the means of distribution for electricity for the vast majority of devices, appliances and machines in households and factories and just about every other electrified thing in the world today.

But even as Tesla was inventing much of the technology used in the alternating current electricity supply system, another famous inventor, Thomas Edison argued that direct current was the best way to distribute electricity.

By the time Tesla tech came onstream, DC had already been in use for a decade, but within a relatively small area, and Edison lost that argument mostly because the components of an alternating current grid enabled electricity to be carried far and wide beyond the power generating facility.

Manufacturing: Benefits of universal peripherals

Benefits of using peripherals — Even drives with onboard brake choppers are not rated sufficiently for the braking demand of the application

John Mitchell, global business development manager of maintenance and repair specialist CP Automation, discusses the benefits of using a universal brake chopper that works with any inverter

There is a real danger in the specification of inverters for use in heavy-duty applications. Fresh from the manufacturer, most drives – even ones with onboard brake choppers – are not rated sufficiently for the braking demand of the application.

Non-specialist engineers face an extremely complex task when asked to choose the correct inverter, resistor and brake-chopper combination for a project.

To help counteract this problem, CP Automation recommends using an external brake chopper unit that simplifies the process of inverter selection. Where an inverter doesn’t feature a built-in brake chopper, the new CP Automation unit, manufactured to the highest standards, supplies that functionality. It’s a universal model that works with any inverter, from any manufacturer. [Read more…] about Manufacturing: Benefits of universal peripherals
