The Emerging Electrical Markets for Copper

Without any enhancement, it may take 15 hours to charge a PHEV battery, based on the United States 100 volt infrastructure. Upgrading this to a 220 volt 15 AMP connection would reduce the charging time for a 24 kWh battery to 8 hours; a 30 AMP connection would halve this. The cost of such enhanced connections is around US$500-1,000 currently. ................
