Importance of Workplace Charging
 Fills a critical gap in PEV
Infrastructure needs
 Provides an attractive
employee benefit
 LEED standard and
reduction of GHGs
 Allows for more electric
only miles for PHEV’s
 Creates local ‘PEV
showrooms’ for info sharing
on vehicles
 EV’s can act as ‘employee
pool cars’ for day trips

employees
• Green your image
• Improved commute –
increased employee
productivity
• Help comply with local
