Challenge 1: Real-time communications
Real-time communications needed for:- Quick problem solving- Ability to book charging stations- Support the smart grid with load adjustment/shedding
Solution:
Page 8
Solution:- Event-driven architecture- GPRS/UMTS and SMS redundant channels- Use landline channels where available

Challenge 2: Independence from land lines
Independence from land lines needed for:- Remote locations- Easy deployment with unified architecture and security
Solution:- Use of wireless technology (GPRS/UMTS)
Page 9
- Use of wireless technology (GPRS/UMTS)- Providing support for land lines where available

Challenge 3: Communications security
Communications security paramount because:- Smart grid may be directly impacted- Financial issues linked with billing of station usage
Solution:- Personal RFID identification on the station - security
Page 10
- Personal RFID identification on the station - security- Embedded software security mechanisms- Secured access on the server application side

Challenge 4: Third-party interconnections
Third-party interconnections needed for:- Allowing partnerships with other stakeholders- Making the EV stations taking inputs from the smart grid- Providing a specific interface to different customers
Page 11
Solution:- Use of M2M platform as a data middleware- Use of standardized platform and open web-services

Challenge 5: System evolution
System evolution paramount because:- The infrastructure is being deployed now- We don’t know what the systems will look like in 3 years
Solution:- Use of extendable pieces of hardware
Page 12
- Use of extendable pieces of hardware- Possibility to remotely upgrade equipment firmware- Use of programmable pieces of hardware- Possibility to remotely upgrade equipments software
