This is expected behavior — nothing is being double-billed. Here's what's happening:

**The 10,800 yen annual payment covers only the PowerX First membership fee, not the electricity itself.**

- **Membership fee (what you paid):** The Annual Plan is 10,800 yen, billed once at enrollment and again at renewal — this is the flat fee for belonging to PowerX First (/sources/en/reference/membership.md:131).
- **Charging fee (what you're seeing on usage dates):** Every time you charge, a separate usage fee applies based on the amount of electricity delivered. As a First member, you pay the discounted rate of **from ¥45/kWh** (compared to ¥65~ for regular users), and this is charged in addition to the membership fee each time you charge (/sources/en/runbooks/membership.md:278–282).

So on each date you use a station, you'll see a charge for the kWh you consumed at the First-member rate. What your annual fee gets you is:

- The discounted per-kWh rate (¥45~ vs. ¥65~)
- Reservations up to 3 days in advance (vs. 30 minutes ahead for regular users)
- Timeslots up to 75 minutes (vs. 30 minutes)
- Up to 150 kW ultrafast charging at eligible stations

In other words, the annual plan is a membership discount program, not an all-inclusive charging pass — the usage fees you're seeing are the per-kWh charging costs at your member rate, billed separately from the 10,800 yen membership fee.

ご説明いたします。これは仕様上、正しい請求となります。

**年払い10,800円は「会費」であり、充電料金は含まれていません。**

PowerX Firstは、会費（年払い10,800円／税込、月払い1,050円）を払うことで会員価格で充電できるようになる制度です。充電料金自体は会費とは別に、利用した分だけ都度（従量課金）発生します（/sources/ja/runbooks/membership.md:278、会費プランの詳細は /sources/ja/public-help/articles/36916548707353.md:31）。

つまり、年払いのお支払い後の利用日に請求されているのは、**その利用分の充電料金**です。First会員の場合、充電単価は一般価格より安い会員価格（エコノミー45円〜/kWh など、拠点のグレードにより異なる）で計算されます。なお、拠点によってはFirst価格の対象外となる場所もあります。

もし、請求されている金額が充電料金ではなく、会費と同額（10,800円や1,050円など）の重複請求に見える場合は、通常とは異なるため確認が必要です。その際は、アプリの利用履歴・請求画面のスクリーンショット、ユーザーID、電話番号、メールアドレス、クレジットカード番号下4桁をお知らせいただければ、詳細を確認いたします。

The 10,800 yen is the PowerX First **membership fee** (annual plan), not a charging allowance — so the two charges are separate things and both are expected.

What each charge is:

- Membership fee: ¥10,800 (tax incl., ≈¥900/month) billed once a year on your enrollment anniversary date, auto-renewed to your registered card. This buys the member benefits (discounted kWh price, reservations up to 3 days ahead, up to 75-minute slots, no cancellation fee).
- Charging fee: billed separately, pay-as-you-go per kWh, every time you charge. For First members the guide rates are from ¥45/kWh (Economy), ¥50 (Regular), ¥55 (Premium) — i.e. ¥20/kWh off the general ¥65/70/75. Each session is charged to your card, and the date it appears depends on your card company.

So the amounts on your later usage dates are the per-session charging fees, not a second membership charge. Note also that the membership fee itself does not show up in the app's usage history — only charging sessions do.

Two things worth verifying on your side:

1. That member pricing was actually applied: check the per-kWh unit price on those sessions. If it shows the general rate (¥65–75/kWh) rather than the First rate (¥45–55/kWh), that needs to be checked. Plan changes only take effect once the current term ends (stop auto-renewal, then re-select the plan after expiry), so sessions billed around a switch date can be worth reviewing.
2. Your active plan: Account > PowerX First > payment plan confirmation.

If you send me the usage dates and the per-kWh amounts (or the line items from your statement), I can tell you whether the member discount was applied correctly. I can't view or refund charges myself — if a session was mis-billed, it would need to be reviewed by the billing team.

ご質問の「別途請求されている分」は、会費ではなく**充電料金（従量課金）**である可能性が高いです。

**仕組み**
PowerX Firstの年払い10,800円（税込・月あたり900円換算）は「会員費」であり、充電そのものの料金ではありません。充電は電力量（kWh）単位の従量課金で、ご利用のたびに都度ご登録のクレジットカードへ請求されます。会費は入会時または自動更新日に決済されるもので、両者は別建てです（/sources/ja/public-help/articles/40049805074585.md:20-26、/sources/ja/public-help/articles/36916548707353.md:31-34）。

First会員の場合、充電単価は一般利用より1kWhあたり20円引きとなり、目安はFirst 45円〜／一般 65円〜（メニューにより一般65・70・75円、First 45・50・55円）です（/sources/ja/reference/membership.md:149-155、/sources/ja/runbooks/charging-use.md:248）。時間ではなく実際に充電した電力量×単価で決まります（/sources/ja/runbooks/billing.md:193）。

**念のためご確認いただきたい点**
- アプリ「アカウント＞PowerX First＞お支払いプランの確認」で、年払いに切り替わっており有効期限も更新されているか（/sources/ja/public-help/articles/36916548707353.md:36-40）
- 割引が適用されるのはFirst加盟拠点（地図上の赤字「F」表示）です。非加盟拠点では一般料金が適用されます（/sources/ja/runbooks/charging-use.md:65）
- 請求額そのものに覚えがない場合は、充電終了時の与信（オーソリ）枠確保の通知で、実際には請求されていないケースもあります（/sources/ja/public-help/articles/40567501317657.md:20-22）

なお、会費（10,800円）はアプリの利用履歴には表示されません。領収書が必要な場合はお申し出ください（/sources/ja/runbooks/billing.md:208）。

上記でも金額が合わない場合は、利用日・ステーション名・請求額をお知らせいただければ、内容を確認のうえご案内します。充電単価は改定される可能性があるため、最新の価格はアプリ内の各ステーション料金表示でもご確認ください。
