Latest Technologies for Quick Charging and Power Supply Systems for EVs

To realize a low-carbon society and thus curb global warming, countries are developing new energy sources to replace fossil fuels. In Japan, the Great East Japan Earthquake of March 2011 has prompted a major energy policy turnaround: from the conventional strategy of using nuclear power, a non-fossil-fuel energy source, to far greater use of renewable energy sources like solar power.

This summer there are expected to be energy shortages in West Japan and other regions of the country, and these will likely be met with rolling blackouts such as the kind initiated in the Tokyo area last year.

While there will be a change to a greater proportional use of renewable energy, what won’t change is the need for a stable supply of electricity for improving people’s lives and advancing economic development.

For the time being, society has no choice but to manage its energy use efficiently by saving, generating, and storing the limited electricity available to it. One proposal for effective energy management is to make use of storage-capable lithium-ion batteries to store plentiful night-time electricity and use it for peak-time shifts in the daytime.

1) Quick Chargers for EVs
Towards its goal of realizing a low-carbon society, Japan was the first country to develop EVs (electric vehicles) and install an EV charging infrastructure. In addition, an industry group led by Tokyo Electric Power Company has proposed an international standard for quick chargers called CHAdeMO. A number of manufacturers in Japan and other countries are already offering products that use this standard, and over 1,200 CHAdeMO-compatible quick chargers have been installed worldwide.

Nichicon is a developer and manufacturer of OBCs (on board chargers), the devices that charge the lithium-ion batteries found inside EVs. Most of today’s mass-produced EVs are equipped with Nichicon OBCs.

Nichicon is also contributing to the spread of charging infrastructure: it has applied its technology to a four-product lineup (10-, 20-, 30-, and 50kW) of the world’s smallest and lightest quick chargers for EVs.

2) Quick Charging System Combining Solar Power and Energy Storage
50-kW-class quick charging systems often require high-voltage electrical equipment, but Nichicon has developed a quick-charging system that can run on a low-voltage commercial power source. This system has been installed at the Suita Service Area on the Meishin Expressway in West Japan. This quick charging system combines solar power and a lithium-ion storage battery, so it has the advantage of being able to operate on its own as an emergency power source.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
