Error code 244 typically means the vehicle hasn't granted charging permission, or a communication timeout occurred between the charger and the car — it's not necessarily a charger fault.

Please try the following, in order:

1. Unplug the connector and reinsert it firmly until it locks.
2. Confirm the shift is in P (Park), the vehicle power is OFF, and your vehicle's charging settings (timers, etc.) are correct.
3. Retry charging from the app.
4. If it still fails, move to the charger on the opposite side and try again.
5. If the opposite side also fails, please use another station for today.

If the error persists even after trying the opposite charger, let us know and we'll investigate the unit on our side. When you contact us again, it helps to have your user ID, vehicle info, date/time, station, left/right side, LED color, and the error code shown.

This guidance is based on our internal troubleshooting runbook (/sources/en/runbooks/charging-troubleshooting.md:239-243 and :281-285); the public Help Center doesn't currently have a dedicated article for error 244.

エラーコード244は、車両側から充電許可が下りていない、または通信タイムアウトが起きている可能性があるエラーです（/sources/ja/runbooks/charging-troubleshooting.md:243）。

以下の順でお試しください。

1. **コネクタの抜き差し**：一度充電ガンを抜いて、改めてしっかり差し込み直してください。
2. **車両状態の確認**：シフトがPに入っていること、電源がOFFになっていること、車両側の充電設定を確認のうえ、再度充電を開始してください。
3. **反対側の充電器で再試行**：同じステーションの反対側の充電器に移動してお試しください。片側で開始できない場合でも、反対側では正常に充電できることが多いです（同ファイル:285）。
4. **別ステーションでの再試行**：反対側でも開始できない場合は、お手数ですが別のステーションをご利用ください。

上記を試しても改善しない場合は、こちらで調査いたしますので、その旨をお知らせください。その際、ステーション名と充電器の左右（DU番号）をあわせてご連絡いただけるとスムーズです。

Error 244 on a PowerX charger generally means the charger didn't get charging permission from the vehicle, or the hand‑shake between charger and car timed out — it's a communication issue rather than a fault you can see on the C40 itself (QA runbook CS‑033: /sources/en/runbooks/charging-troubleshooting.md:243).

Please try this in your 17:15 slot, in order:

1. Unplug the connector and reinsert it firmly until you hear it click ("カチッ") — the start screen should appear once it's seated properly.
2. Set the gear to P, switch the vehicle power fully OFF, and confirm the vehicle's charging settings (charge limit / scheduled or timer charging) aren't blocking the start. Some models require power off during charging.
3. Press start again in the app. Within your reserved time you can retry as many times as needed.
4. If it still shows 244, move the car to the opposite / adjacent charger and start again from the QR scan. If that side also fails, please use another station.
5. If nothing works, contact PowerX support from the app with: the diagnostic code shown on screen (244), the station name, which charger side (left/right), your reservation start time (17:15), and the vehicle (Volvo C40). The official help center asks for exactly this — the diagnostic code displayed in the app — so support can investigate the charger.

Two notes for transparency: the public Help Center does not publish a per‑code list, so the specific meaning of 244 comes from internal QA guidance (provisional, last reviewed 2026‑08‑17), and the related Volvo 243/244 entry is flagged as time‑sensitive. Also, I haven't changed or extended your reservation or opened a charger investigation ticket — if you need either, tell me and I'll pass the details to support for confirmation.

ご不便をおかけしております。エラーコード244は、充電器が車両から充電許可を得られていない、または充電器と車両間の通信がタイムアウトしている場合に表示されることが多いものです（車両側に不具合がなくても発生します）。

まず、以下の順でお試しいただけますか。

1. コネクタを一度完全に外し、「カチッ」と音がするまで奥まで差し直す
2. シフトをPに入れる／車両の電源をOFFにする／充電-related 設定（予約充電・タイマー充電の予約が入っていないか等）を確認する
3. アプリ上で「再度充電する」を押し、表示されたQRコードをもう一度充電器にかざして開始する（ご予約時間内であれば再充電は可能です）
4. それでも開始しない場合は、同じステーション内の反対側の充電器へ移動して再試行する
5. 反対側でもダメな場合は、恐れ入りますが別のステーションをご利用ください

それでも改善しない場合は充電器側の不具合の可能性もありますので、次の情報を添えてカスタマーサポートまでご連絡ください。調査の手配をいたします。

- エラーコード（244）が表示された画面
- ステーション名と充電器番号（左／右）
- 予約日時（17:15の枠）
- 車両（ボルボC40）
- 上記1〜4を試した結果

なお、アプリに診断コードが出ているケースは、そのコード控えのご提示を前提にサポート側で確認する運用となっています。また、この案内には時期により運用が変わる部分が含まれるため、実際の対応は最新のご案内を優先いたします。
