What is the difference between ISO 15118 and IEC 61851 ?

Title: A Comparison of ISO 15118 and IEC 61851 for EV Charging Infrastructure

Electric vehicles (EVs) have gained significant popularity in recent years due to their environmental benefits and growing infrastructure. However, the rapid growth in EV adoption has led to a lack of standardization and interoperability in the charging infrastructure. The International Electrotechnical Commission (IEC) has developed IEC 61851, a standard primarily focused on defining the charging modes and related requirements for EVs. This standard has the potential to address the differences between ISO 15118 and IEC 61851, ensuring a consistent approach to EV charging.

ISO 15118 and IEC 61851: Defining EV Charging Modes

ISO 15118 and IEC 61851 are both essential standards for EV charging infrastructure. While ISO 15118 primarily focuses on communication protocols between the EV and the charging infrastructure, IEC 61851 concentrates on defining charging modes and related specifications to provide a standardized approach for charging EVs.

ISO 15118 defines several charging modes, including Mode 1, Mode 2, Mode 3, and Mode Each mode corresponds to different charging capabilities and requirements. For example, Mode 1 refers to a basic level of charging using a standard domestic socket, while Mode 4 represents fast-charging stations with high-power output capable of delivering energy quickly.

IEC 61851, on the other hand, defines several charging modes, including VCharging, PWVCharging, and EVCharging. These modes are based on the different levels of power delivery and the time taken to charge an EV. VCharging is a low-power charging mode, while PWVCharging and EVCharging provide higher levels of power delivery.

Differences between ISO 15118 and IEC 61851

Although both ISO 15118 and IEC 61851 are essential standards for EV charging infrastructure, they serve different purposes. ISO 15118 primarily focuses on communication protocols between the EV and the charging infrastructure, ensuring secure and efficient exchange of information.

On the other hand, IEC 61851 concentrates on defining charging modes and related specifications to provide a standardized approach for charging EVs. IEC 61851 defines several charging modes, including VCharging, PWVCharging, and EVCharging, based on the different levels of power delivery and the time taken to charge an EV.

Conclusion

In conclusion, ISO 15118 and IEC 61851 are two important standards for EV charging infrastructure. While ISO 15118 focuses on communication protocols between the EV and the charging infrastructure, IEC 61851 concentrates on defining charging modes and related specifications to provide a standardized approach for charging EVs. The differences between these two standards can help ensure interoperability and standardization in the EV charging industry. Adopting a standardized approach to EV charging can help promote a more efficient and connected charging experience for EV drivers.
