IEC 63119

IEC 63119 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IEC 63119 rather than just read about it. In short: IEC 63119 is an international standard defining a protocol for information exchange for electric vehicle charging roaming services, which is currently under development. IEC 63119 is one of the International Electrotechnical Commission's group of standards for electric road vehicles and electric industrial trucks, and is the responsibility of Working Group 9 (WG9) of IEC Technical Committee 69 (TC69).

Key takeaways

IEC 63119 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IEC 63119 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IEC 63119 from memory before moving on to harder problems.

Reference excerpt

IEC 63119 is an international standard defining a protocol for information exchange for electric vehicle charging roaming services, which is currently under development. IEC 63119 is one of the International Electrotechnical Commission's group of standards for electric road vehicles and electric industrial trucks, and is the responsibility of Working Group 9 (WG9) of IEC Technical Committee 69 (TC69).

Standard documents IEC 63119 consists of the following parts, detailed in separate IEC 63119 standard documents:

IEC 63119-1: General, edition 1 published in 2019. IEC 63119-2: Use cases IEC 63119-3: Message structure IEC 63119-4: Cybersecurity and information privacy

Worked examples

Example 1 — a first encounter with IEC 63119

Start with the simplest possible case. Write down what IEC 63119 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IEC 63119 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IEC 63119 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IEC 63119

In research: IEC 63119 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IEC 63119 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IEC 63119 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Electric vehicles, IEC standards, so understanding it makes those chapters shorter.
In everyday life: Look for IEC 63119 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is IEC 63119 in simple terms?

Why does IEC 63119 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study IEC 63119?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
