Over the past year, UPS and EVI
have worked to develop the zero-emissions vehicle - the EVI-WI - to meet the
needs of the parcel delivery service industry. The EVI-WI is built on a glider
produced by Freightliner Custom Chassis Corp. The chases is then equipped with
an Utilimaster body.
Earlier this year, EVI received
California Air Resource Board (CARB) approval for the EVI-WI. This will allow
customers who purchase the EVI-WI to take advantage of a $20,000 CARB rebate
through the Hybrid Truck and Bus Inventive Project.
Both UPS and EVI have a long
history of efforts to reduce energy consumption. UPS says it has been
supporting alternative fuel technologies since the 1930s. The carrier currently
operates 2,000 alternative-fuel vehicles worldwide that are powered by a
variety of hybrid, electric and natural gas technologies. EVI has been
manufacturing zero-emission, all-electric power trains for 20 years, according
to the company.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
