You're charged only for what you actually used — not the full booking.

PowerX charging is billed on a usage-based (pay-per-electricity) system, so your fee is calculated from the amount of energy actually delivered, not the length of your reservation. In your example, if you book a 30-minute slot but stop after 15 minutes, your charge is: energy delivered in those 15 minutes × the unit price. You would not pay for the unused 15 minutes.

A couple of related points that may help:

- **How to stop:** Tap the "Charge Stop" button in the app, and once it says "Please remove the charging connector," unplug it from your car (per the official Help Center article on stopping charging mid-session).
- **Payment timing:** The fee is finalized after your reservation time ends. PowerX places a pre-authorization (hold) on your card when you book, and once the final fee is determined, only the actual charging amount is collected and the rest of the hold is released — typically within about an hour after the reservation ends.

So stopping early simply means a smaller bill based on the electricity you received.

途中で充電を止めた場合は、**止めた時点までに実際に充電した電力量に応じた料金**となります。いつ止めても30分間分の料金がかかる、ということはありません。

PowerXの充電料金は、予約した時間幅ではなく「使用した電力量に対する従量課金制」です（公式ヘルプ: `/sources/ja/public-help/articles/24098543153433.md:42`）。そのため、30分の予約枠で15分で停止した場合は、「15分間で充電された電力量 × 充電単価」が料金となり、残り15分分の料金は発生しません。

なお、アプリの「チャージストップ」ボタンで停止した後は「充電コネクタを抜いてください」と表示されたら、コネクタを車から外して本体のホルダーに戻してください（`/sources/ja/public-help/articles/23458810436633.md`）。

Output

You’re charged only for the electricity actually delivered—not for the full reserved time.

For example, if you book 30 minutes but stop after 15 minutes, the charging fee is based on the kWh charged during those 15 minutes multiplied by the applicable unit rate. The unused 15 minutes are not billed.

Output

途中で停止された場合は、実際に充電した分だけの料金になります。

PowerXは使用した電力量に対する従量課金制です（/sources/ja/public-help/articles/24098543153433.md:42）。したがって30分の枠でご予約いただいても、15分で停止されれば、充電料金はその15分間に充電された電力量×充電単価となり、予約時間枠ぶんの料金が丸ごと発生するわけではありません（/sources/ja/runbooks/billing.md:240）。

停止方法は、アプリの「チャージストップ」ボタンを押していただき、「充電コネクタを抜いてください」と表示され次第、コネクタをお車から外してください（/sources/ja/public-help/articles/23458810436633.md:18）。なお、予約時間終了後に充電器の占有料金は、現時点では発生いたしません（/sources/ja/public-help/articles/28501958588313.md:20）。

一点ご留意いただきたいのは、精算・明細の表示タイミングです。料金は予約時間の終了後に確定する仕組みで、決済時に確保（オーソリ）していた金額から実際の充電料金分のみを徴収し、残りは返金されます（目安は予約時間終了後1時間以内）。明細や領収証も予約時間終了してから表示・発行可能になります（/sources/ja/public-help/articles/24625279158553.md:42、/sources/ja/public-help/articles/23683261338649.md:52）。そのため、早めに停止された直後は明細がまだ出ておらず、確保していた金額が一時的に利用通知として表示される場合がありますが、確定するのは実際の充電量に基づく料金です。
