Bi-Directional DC/DC Converter Reduces Costs

Image
A consortium led by Prodrive has developed an approach to the configuration of DC/DC converters that will reduce the cost, weight and package space associated with electric vehicle battery packs. The system is said to address the spiralling costs of energy storage by increasing the voltage available at the traction motors. To improve efficiency, electric motors require ever wider speed ranges; as speed is proportional to voltage, electric vehicles and hybrids are progressing from 300V to 600V systems. This creates a challenge because battery chemistry dictates the voltage per cell, so doubling the voltage with the same battery chemistry means doubling the number of cells, incurring cost, weight, and packaging penalties. More cells, or a switch to an alternative chemistry, may also exacerbate challenges such as thermal management, availability, environmental protection and end-of-life recycling. To address this challenge, the consortium (which also includes the University of Manchester

Airchannel Helps With R-22 Refrigerant Phase Out

Image
Airchannel is helping companies comply with legislation that phases out and removes the refrigerant R-22 from their compressed-air systems. Under EU Ozone Regulation EC2037/2000, the use of virgin R-22 refrigerant will be banned from the end of this year, as it contains ozone-depleting hydrochlorofluorocarbons (HCFCs). R-22 is used in a range of industries. From January 2010 to January 2015, recycled HCFCs will be permitted but it is expected that supplies will be limited. For companies using R-22 within their compressed-air system, this could result in a significant operational headache. The likelihood of compressed-air systems using R-22 as a coolant increases significantly for equipment that is more than 10 years old. However, the legislation also represents an opportunity to help resolve two major issues facing industry - the rising cost of energy and environmental compliance. Andrew Barraclough, national sales manager for Airchannel, said: 'R-22 will be totally phased out fro
