Plug & Charge, ISO 15118 and the Role of Root CAs

The ISO 15118 Plug & Charge standard relies on trusted certificate authorities (CAs) to authenticate vehicles, charging stations, and backend systems. Two major players operate today:

1. Hubject V2G Root CA (long-standing operator, widely embedded in European vehicles)
2. Irdeto CrossCharge / CharIN PKI (recently took over operation of CharIN’s PKI, expanding in Europe & North America)

For EV adoption, it is crucial to know which OEMs are likely to trust which Root CA.

The last months have been busy with (re)starting teams somehow. This is a small note to self in order to keep a record of aspects that need to be addressed.

The kick off is the first step of a continuous mechanism to learn and deliver the best possible outcome for your audience.

Ensure your kick off allows to change everything, including the process.

Process, Content and Operations need to be part of the kick off.

Everyone in software development knows the words: ‘just add this small thing and…’.
Mostly the people requesting the addition don’t have to live with the consequences. These consequences double each and every time you add another option to an existing structure.

Every option you add, adds to the number of combinations your software must be capable to handle and combinations double according to the formula 2^n. So when you say yes for the 7th time. you go from 64 (2^6) to 128 (2^7) combinations that need to work and tested.

Today a respected colleague called and we had a conversation on technology choices. A team choose the React framework over the Angular framework and that caused a stir at the company.

He asked me what my top 5 elements for selection would be.

We ended up that a single question to answer should be enough.
Will the whole team take the responsibility to make this choice a success ?

Sometimes the actual technology matters, most of the times, it matters more that ownership is at the right spot.

A little history: Scrum, KanBan and DevOps

Over the past 15 years, the IT industry has taken to working ‘agile’, often by introducing Scrum. Scrum is development process, which creates a cadence of sprints that last a few weeks each.

User stories are used to determine the work to be done. These user stories are planned, committed, built and delivered. There is also room to evaluate the work, the object being to improve together.
