No — the fee is not based on charging time. PowerX uses usage-based (pay-per-kWh) billing: you pay for the amount of electricity you actually charge, not for how long the session takes.

A few practical points:

- Since November 18, 2024, billing has been on a volume-based (per-kWh) system (official Help Center: /sources/ja/public-help/articles/26574552466457.md:20).
- Even if you stop partway through a reservation (e.g., 15 minutes of a 30-minute booking), you're only billed for the kWh delivered during that time, multiplied by the unit rate (/sources/en/runbooks/billing.md, CS-141).
- The per-kWh rate depends on the charging menu you select (e.g., Economy / Regular / Premium), and joining PowerX First gives a lower per-kWh price than general use (/sources/en/runbooks/billing.md, CS-128).

So a longer session doesn't cost more by itself — only a larger amount of energy charged does. You can check each station's pricing menu in the PowerX app.

充電料金は「充電時間」そのものでは決まらず、**充電した電気量（kWh）に応じた従量課金制**です。

- 2024年11月18日以降、従量課金制でのお支払いとなっています（/sources/ja/public-help/articles/26574552466457.md:20）。
- そのため、予約枠（例：30分）を残っていても、実際に充電した電力量分のみの請求となります。例えば30分の予約で15分で終わった場合は「15分間で充電された電力量 × 充電単価」が料金になります（/sources/ja/runbooks/billing.md:244）。
- なお、1kWhあたりの単価はご利用のメニュー（Economy・Regular・Premiumなど）によって異なります（/sources/ja/runbooks/billing.md:136）。各ステーションの充電料金メニューはアプリ内でご確認いただけます。

つまり、同じ時間でも充電スピードや充電量によって金額は変わり、逆に時間が短くても充電量が多ければ料金は高くなります。

No — the charging fee itself is not billed by the minute. PowerX uses a volumetric (pay‑for‑what‑you‑charge) model, so the amount depends on the kWh delivered, not how long you stay plugged in.

Key points:

- Charging fee = kWh charged × the per‑kWh price of the menu you selected at that station (Economy / Regular / Premium, and PowerX First rates where applicable). Check the menu shown in the app for the station. /sources/ja/public-help/articles/26574552466457.md:20, /sources/en/runbooks/billing.md:131-135
- Longer sessions usually cost more only because more energy goes into the battery; a slow charge that delivers the same kWh costs the same.
- No overstay/occupancy fee is charged after your reservation time ends (as stated in the official article; PowerX notes this can change without notice). /sources/ja/public-help/articles/28501958588313.md:20
- Separate charges that are not time-based: the PowerX First membership fee (from about ¥900/month), a ¥500 cancellation fee when the cancellation policy applies, and facility parking fees, which are generally at your own expense (some stations are free, and some offer a ¥400 parking-fee-equivalent discount off the charging bill). /sources/ja/public-help/articles/16819739268249.md:30, /sources/ja/public-help/articles/22881312858393.md:20-22, /sources/ja/public-help/articles/44461176251801.md:20-25

One nuance: at the start of a session the payment system places a credit authorization hold, and the actual amount is settled after charging ends, so the figure your card shows initially is not the final charge. /sources/en/runbooks/billing.md:100-104

If you tell me the station and menu, I can point you to the specific rates listed for it.

充電料金は「時間」ではなく「充電した電力量（kWh）」に対して課金される従量課金制です（2024年11月18日より適用）。

- /sources/ja/public-help/articles/26574552466457.md:20
- /sources/ja/public-help/articles/24098543153433.md:42

したがって、料金＝充電された電力量（kWh）×そのステーション・メニューの1kWh単価 で決まり、充電にかかった分数そのものが課金対象になるわけではありません。

時間との関係でよくあるご質問は次のとおりです。

- 途中で止めた場合：30分枠を予約していても、15分で停止すれば「15分間に充電された電力量×単価」のみです（/sources/ja/runbooks/billing.md:244）。
- 予約時間を過ぎた場合：現時点では予約時間終了後の超過料金は発生しません（/sources/ja/public-help/articles/28501958588313.md:20）。予約時間が終わると充電自体も停止します（/sources/ja/public-help/articles/24098543153433.md:41）。
- 同じ時間でも金額が変わることがある：充電出力はバッテリー状態によって上がるため、同じ30分でも充電できたkWh数が違えば請求額は変わります。

なお、1kWhあたりの単価は、料金メニュー（Economy／Regular／Premiumなど）、ステーション、PowerX First会員か一般利用かによって異なります。各ステーションの適用メニューと単価はアプリ内でご確認いただけます。
