Table 4 Candidate communication technologies customer-to-grid interaction for garage charging
From: A survey on communication technologies and requirements for internet of electric vehicles
Technology | Pros | Cons |
|---|---|---|
Power line communications | Every EV owner has an access. Easy penetration | Indoor applications are not allowed in every country. Regulatory and technical issues |
White-space networking | High penetration and coverage | Require technologies to operate at varying bandwidths |
Utility-owned wired infrastructure | Full control over the network. No need for interoperability among various standards | Very high cost and cost of ownership is not clear |
Fixed broadband | Low cost (customers already have it) | Level of broadband deployment can be problematic |
Wireless cellular networks | Easy adoption with already existing structure | Coverage is limited in developing countries |
WiFi mesh network | Low cost, unlicensed frequency band | May require complex designs |
