Зарядна станція заряджає акумулятор.

Because зарядна is an adjective describing станція, and it has to agree with the noun in gender, number, and case.

• станція is feminine
• singular
• here it is in the nominative case because it is the subject

So the adjective also takes the feminine singular nominative form:

• masculine: зарядний
• feminine: зарядна
• neuter: зарядне

So зарядна станція = charging station.

Usually, yes. A noun ending in -я is very often feminine in Ukrainian, and станція is feminine.

That is why you get:

• зарядна станція
• not зарядний станція

A learner should still remember that noun gender is something to learn with each word, but in this case the ending gives a strong clue.

Заряджає is the 3rd person singular present tense form of заряджати, which is an imperfective verb.

So it means:

• charges
• is charging

Both are possible in English, depending on context.

In this sentence, заряджає matches the singular subject станція:

• я заряджаю = I charge / am charging
• ти заряджаєш
• він/вона заряджає

This is about aspect.

Ukrainian usually has two related verbs:

• заряджати = imperfective
• зарядити = perfective

Their meanings are close, but they are used differently:

• заряджати focuses on the process, repetition, or general action
• зарядити focuses on completing the action

So:

• станція заряджає акумулятор = the station charges / is charging the battery
• станція зарядить акумулятор = the station will charge the battery fully / will complete the charging

Also, in modern Ukrainian, the perfective verb normally does not have a true present tense meaning. A form like зарядить is understood as future, not present.

It actually is in the accusative case, because it is the direct object of заряджає. But for an inanimate masculine singular noun like акумулятор, the accusative form is the same as the nominative form.

So:

• nominative: акумулятор
• accusative: акумулятор

That is normal in Ukrainian.

Compare that with an animate masculine noun, where accusative would often look like the genitive instead.

Yes. In Ukrainian, акумулятор commonly means a rechargeable battery, especially in technical contexts, vehicles, electronics, or power systems.

Depending on context:

• батарея can mean battery in a more general sense
• акумулятор often specifically means a battery that stores charge and can be recharged

So in a sentence about a charging station, акумулятор is a very natural word.

No. Ukrainian word order is fairly flexible because case endings help show grammatical roles.

Зарядна станція заряджає акумулятор is the neutral, straightforward order:

• subject → verb → object

But other orders are possible, for example for emphasis:

• Акумулятор заряджає зарядна станція
  This can emphasize the battery
• Заряджає акумулятор зарядна станція
  This can sound more marked or stylistic

Even though the order can change, the endings still show that:

• станція is the subject
• акумулятор is the object

No. Ukrainian does not use articles.

So Зарядна станція заряджає акумулятор could mean:

• The charging station charges the battery
• A charging station charges a battery
• The charging station is charging the battery

Context tells you which English translation is best.

A helpful pronunciation guide is:

zaryadna stantsiya zaryadzhaye akumulyator

Approximate stress:

• заря́дна
• ста́нція
• заряджа́є
• акумуля́тор

A few useful notes:

• я often sounds like ya
• є in заряджає sounds like ye
• ж sounds like the s in measure
• the cluster дж sounds like j in jam

So заряджає is roughly za-ryad-ZHA-ye.

They are related to the same idea of charge, but they are different parts of speech:

• зарядна = adjective, charging
• заряджає = verb, charges / is charging

So:

• зарядна станція = charging station
• станція заряджає = the station charges

This is very common in Ukrainian: related words can share the same root but have different endings and grammatical jobs.

Yes. The Ukrainian present tense of an imperfective verb often covers both meanings.

So заряджає can mean:

• charges = general or habitual action
• is charging = action happening right now

Only context makes it clear which one is intended.

For example:

• Ця станція заряджає акумулятор за дві години.
  = This station charges the battery in two hours.
  habitual / general

• Зараз станція заряджає акумулятор.
  = Right now the station is charging the battery.
  ongoing action

Yes, but the meaning changes a bit.

• зарядна станція = charging station
• зарядний пристрій = charger / charging device

So if you mean a larger station, dock, or charging point, зарядна станція is appropriate.
If you mean a charger as a device, зарядний пристрій may be better.

Both are correct Ukrainian, but they are not always interchangeable.

Sometimes, yes. Ukrainian often allows the subject to be omitted if it is already clear from context.

For example:

• Заряджає акумулятор. = It is charging the battery.

But in this sentence, keeping зарядна станція makes the meaning clear and natural, especially if you are introducing the subject for the first time.

So the full sentence is the best basic version for a learner:

Зарядна станція заряджає акумулятор.
