  2. EV Project Deployment

  3. Smart EVSE • Color touch screen • Real time communications • LAN, CDMA, WiFi, AMI • Certified utility meter • Reservation capable • Smart phone & web controls • Host web portal • 360o beacon light • ADA compliant • Cord management • Specified advertising space

  4. Network and Mobile

  5. Current Installs

  6. Benefits of Submeter in EVSE • Minimize Cost • Ease of Installation • Reduce Power Diversion • Aesthetics • Differentiate Electricity for Transportation • Enables Rate Design

  7. Communication Options Sub-meter embedded in EVSE communicates securely with 3rd party EVSP cloud based system. EVSP system in turn communicates securely with Utility MDMS Sub-meter embedded in EVSE communicates securely with utility as end node attached to the AMI edge router (using vendor specific AMI protocol e.g. SSN’s 802.15.4 mesh) Sub-meter embedded in EVSE communicates securely with utility via premises smart meter using utility controlled HAN network e.g. ZigBee SEP 1 1 EVSE Provisioning & Mgmt System SSL/VPN Premises Broadband Router EVSP Secure Cloud Services Internet Utility AMI Network Energy Database SSL/VPN 2 2 Utility MDMS AMI NAN Router AMI headend Premises Smart Meter EVSE 3 3 Utility AMI Network AMI NAN Router AMI headend
