The ISO 15118 Manual is for beginner and experts alike, being in-depth and comprehensible at the same time.
You will be guided through all the steps that are necessary to carry out a complete charging session between an electric vehicle and a charging station, focussing on the convenient Plug & Charge feature.
Learn about the ISO 15118 document family as well as IEC 62196 and IEC 61851 (including PWM signaling) on which ISO 15118 relies for the complete charging process to be carried out.
Get an overview of a typical ISO 15118 charging procedure for AC and DC charging with regards to the necessary messages to be exchanged. Delve right into the use cases related to these charging procedures.
Fully understand the mechanisms applied on transport layer and on application layer to secure the communication between EV and charging station with regards to confidentiality, integrity and authenticity: Elliptic curve cryptography, ECDH key agreement, ECDSA signatures, X.509 certificates, Public-Key-Infrastructures (PKI), TLS handshake, OCSP, ...
Detailed examples of creating and verifying XML-based digital signatures on the basis of an AuthorizationRequest and CertificateInstallationResponse message.
Public-Key-Infrastructures (PKIs) are a system for the creation, storage, distribution and revocation of digital certificates. You will learn about the motivations behind creating the ISO 15118 specific PKI structure, the different types of certificates to be applied as well as the non-functional PKI requirements coming with it.
The convenience feature Plug&Charge which enables an extremely user-friendly charging experience is based on the authentication and authorization through a digital contract certificate. This contract certificate as well as the corresponding private key need to be installed into the EV by means of a provisioning process.
You will be guided through the complete certificate installation process - one of the most challenging parts of ISO 15118 - step by step.
After the provisioning process has been completed, the EV is able to authenticate and authorize itself by using the newly installed contract certificate - without any further interaction needed by the user.
I will show you how this procedure is carried out, how replay attacks are avoided and what messages are exchanged during this communication phase.
The EV and the charging station exchange some charging parameters and technical restrictions for the charging process before the charging loop can be entered.
You will also learn about the concept of renegotiating a charging schedule and influencing the charging process through so-called PMaxSchedules and SalesTariffs, information which can reflect the current grid situation.
This masterclass on ISO 15118 finishes with an extensive chapter that will run you through a complete exemplary DC charging session.
This includes code listings of real request and response messages exchanged between an EV, a charging station and an IT backend which operates the charging station using the Open Charge Point Protocol (OCPP) - currently a world-wide commonly used communication protocol between charging stations and managing IT backend systems.
Finally, we will take a look into the future and see what will change with edition 2 of ISO 15118 and what new features will be introduced, such as wireless charging and communication or bi-directional power transfer.
As you see, the book covers a lot of ground, providing you with all the information you need to master the Vehicle-2-Grid communication technology.
