The Society of Automotive Engineers (SAE) recently announced the revised version of the J1772 electric vehicle (EV) connector, which is said to reduce the charging time of electric vehicles to 10 minutes.
The J1772 connector specification has been around for a decade or so. It initially defined AC Level 1 and AC Level 2 charging levels, and specified a conductive charge coupler specification and AC Level 1 / AC. Level 2 electrical interfaces. In the revised specification announced in mid-October, the DC charging standard was added, defining two levels of charging, DC Level 1 and DC Level 2, and the corresponding charging coupler and electrical interface.
SAE pointed out that the new revised specification added the DC charging function, which means that the charging time of electric vehicles in the future may be shortened to 10 to 20 minutes; this standard is jointly determined with the European automotive industry experts.
Revised J1772 specification added DC Level 1 charging level, support 200~500V DC, maximum voltage current 40kW (80A), estimated charging time (in 20kW external charger), plug-in hybrid vehicle (plug- The hybrid (PHEV) is 22 minutes, and the battery-powered electric vehicle is 1.2 hours. DC Level 2 supports 200~500V DC, maximum voltage current 100 kW (200A), estimated charging time (in case of an external charger of 45kW), PHEV of 10 minutes, and battery type full electric vehicle of 20 minutes.
Please refer to this link for the complete revision of the J1772 specification. “We can now use this specification to provide users with different charging technology choices in a single modular design,†said Gery Kissel, Chair of the SAE J1772 Working Group and GM Engineering Expert.

Hitachi Launches New TX Series Escalator for
India, Asia and the Middle East
Tokyo, August 21, 2017 --- Hitachi, Ltd. (TSE: 6501, [Hitachi") and Hitachi Building Systems Co., Ltd. today announced the launch of the new TX Series escalator for India, Asia and the Middle East. The escalator has already been released in China*1, and will be released in stages across the remainder regions, commencing August 21, 2017.
In July 2016, Hitachi integrated its escalator businesses of Japan and China, consolidating its resources and enhancing its business operations in both countries, centered around its key business location in Guangzhou, China. The new TX Series escalator launched by Hitachi is a model that meets multiple standards in China, India, Asia and the Middle East. The model follows the same concept for the machine room-less elevator for Asia and the Middle East which was launched in September 2016. In addition to conforming to Chinese safety and quality standards for escalator equipment, the TX Series will be manufactured in accordance with Hitachi's own strict standards of safety and quality, adhering to safety standards in all other regions. It also adopts a functional design based on the concept of an escalator that fits closely with the unconscious actions of users, in the pursuit of their ease and comfort.
The TX Series offers flexibility with a selection of various product specifications, as well as its excellent design and safety features, designed to cater to a diverse range of customer needs. It also saves space required for the installation, covering a smaller area in comparison with existing products*2.
Hitachi will begin sales of the TX Series in Thailand, followed by launches in the Philippines, Malaysia and various other regions, and aims to receive orders of 10,000 units in 2018 in China, India, Asia and the Middle East.
Features of the TX Series
-
Safety
The TX Series offers various new safety features designed with optimal user safety in mind. The side portions of the steps are 8 mm higher than the central portion to prevent accidents in which a users' shoe can become caught between the step and the skirt (side wall) of the escalator. The new TX series has also been fitted with brushes located at foot level on the left and right skirts to let users know if their foot comes into contact with the side walls. A special finish has also been adopted for the landing plates at the entry and exit points of the escalator to prevent users from slipping when getting on and off the escalator. -
Design
The TX Series adopts a simple and functional design that offers the smoothness, safety and comfort that users unconsciously expect to experience when riding an escalator. For example, by minimizing the size of the metal frame supporting the escalator's balustrades, the TX Series' design maximizes the size of the glass surfaces, and achieves greater simplicity at the entrance and exit points (landings) by reducing the number of recesses and protrusions around the hand rail. Additionally, by expanding the installation space of the light fixture, the TX Series also enables enhanced lighting options for illuminating the entire surroundings of the balustrades. -
Space saving
By shortening the span dimensions*3 by 150 mm, the TX Series has made it possible to install escalators in more confined spaces where installation presents difficulties with conventional product designs.
