19: DENSO Develops Battery Monitoring Unit for Lithium-ion Batteries

DENSO Corp. has developed its first battery monitoring unit for lithium-ion batteries used in vehicles. DENSO’s new battery monitoring unit utilizes a newly developed voltage control method that uses what is said to be a simpler and lower cost voltage control circuit, compared to the widely used voltage control method used in laptop computers and other hardware. The new product is installed in the Prius Plug-in Hybrid, which Toyota introduced at the end of 2009.

15: EMerge and EPRI Make DC Power Progress at the 2010 Green Building Power Forum

The Electric Power Research Institute (EPRI) and the EMerge Alliance both made progress in the development of complementary dc powering standards at this year’s Green Building Power Forum (GBPF). The EMerge Alliance provided the first public discussion and review of its recentlyreleased dc-power standard for occupied spaces in buildings. EPRI developed the first "dc voltage tolerance envelope" plotting voltage variations versus time for 380Vdc powered equipment. And EPRI and Emerge announced a joint-effort for the promotion and development of dc power infrastructure standards and equipment in various facilities including data centers, industrial installations, and commercial and residential buildings.
