Here's what our official guidance says about each part of your question:

**1. Is the low output because I'm not a member?**
No. Charging output does not differ by membership type — PowerX First members and general users get the same output. Membership only lowers the per-kWh price (and adds reservation benefits); it does not change charging speed. Likewise, the charging menu (Economy/Regular/Premium) changes the renewable-energy ratio, not the speed.

**2. Am I at a disadvantage under time-based pricing when output is low?**
No. PowerX bills by the amount of energy charged (kWh), not by time. So even if the session takes longer at lower output, you pay only for the kWh actually delivered — low output does not put you at a time-based pricing disadvantage.

**3. Is this abnormal?**
In most cases, no — this is expected behavior:
- The charger's maximum output is 150kW when one port is in use, and 120kW when two ports are charging simultaneously (some stations are still limited to 120kW and are being updated to 150kW).
- Output can be automatically limited by ambient temperature and the charger unit's own temperature.
- Output also depends on your vehicle's power acceptance capacity, so depending on the model and conditions, the charger's maximum may not be reached.
- Output gradually declining as the battery's state of charge (SOC) rises is normal charging behavior — the vehicle tapers its acceptance rate as it approaches full. So a drop from 70–90kW as you near full charge, or ~55kW at high SOC, is typically not a fault. A competitor charger showing a higher figure can simply reflect a different vehicle state (e.g., lower SOC) or different conditions at that moment.

**4. What should I check?**
- Make sure the connector is firmly locked, the car is in Park, and any vehicle charging timers/settings are off (vehicle power OFF can help).
- Retry via the app's "Charge again" button, or try the charger on the opposite side.
- If output is severely unstable (e.g., repeatedly fluctuating or dropping to zero), we can review the session logs on our side — no device error is usually found, but we check each case individually.

If it keeps happening, please contact support with your user ID, vehicle model, date/time, station, which side (left/right) you used, and the app/in-car display readings, and we'll investigate the individual case.

ご不安をおかけして申し訳ございません。ご質問の点について、公式ヘルプと社内応対ガイダンスに基づいてご説明いたします。

**1. 非会員だから出力が低い、ということはありません**

充電出力（スピード）は、会員種別（PowerX First／一般会員）や料金メニュー（Economy／Regular／Premium）によって変わらず、すべて共通です。メニューの違いは再生可能エネルギーの比率と1kWhあたりの料金のみで、充電速度には影響しません（/sources/ja/runbooks/compatibility.md の CS-112、/sources/ja/runbooks/charging-troubleshooting.md:460）。

**2. 出力が変動するのは、仕様上の正常な挙動です**

- 充電器の仕様は「1口利用時 最大150kW／2口（2台同時充電）時 最大120kW」です。隣の充電器が同時に使われていると、最大120kWに制限されます（/sources/ja/public-help/articles/23123162280473.md:20）。
- その上で、外気温や充電器本体の温度により自動的に出力制限がかかる場合があります（/sources/ja/public-help/articles/23459356662809.md:16-17）。
- 出力はお車側が受け入れられる電力にも左右されるため、車種や環境要因によっては最大出力に達しないことがあります（同記事）。他社充電器で135kW出た場合でも、機器やその時の温度条件・バッテリー状態が異なるため、単純比較は難しい面があります。
- **満充電（SOC）に近づくにつれて出力が下がるのは、EV急速充電全般に共通する一般的な挙動です**（/sources/ja/runbooks/charging-troubleshooting.md:460）。バッテリー保護のため、充電後半は車両側が受電を絞ります。

つまり、55〜90kW程度への変動や後半での低下は、上記の要因で説明できる範囲であれば異常ではありません。

**3. 「時間料金制で不利」というご心配は不要です**

PowerXの充電料金は時間ではなく、**実際に充電した電力量（kWh）に応じた従量課金制**です（/sources/ja/runbooks/billing.md:193）。出力が低くて充電に時間がかかっても、かかるのは充電された電気量分の料金だけで、時間で不利になることはありません（/sources/ja/runbooks/charging-troubleshooting.md:460）。

**4. 確認すべき点・お願いしたいこと**

以下の範囲で正常かどうか切り分けできますので、ご確認ください。

- 隣の充電器（反対側）が同時に使われていないか（使われていれば最大120kW仕様になります）
- 充電開始直後（SOCが低い状態）でも極端に低いか、それとも後半だけ低下しているか（後半の低下は正常）
- エラーコードの表示や途中停止の有無（エラーが出る場合は機器側調査の対象になります）
- コネクタが「カチッ」とロックするまで差し込まれているか、車両側の設定（タイマー等）・シフトP・電源OFFに問題がないか

そのうえで、**車種、充電日時、ステーション名と左右（DU1/DU2）、表示されたエラーコード、アプリや車内の表示内容**をご教示いただければ、当方で充電ログを確認し、機器側の異常がないか個別に調査いたします（/sources/ja/runbooks/charging-troubleshooting.md:460、CS-144の対応例も同様です）。明らかに機器起因と判明した場合は、担当部署での調査・改善対応をいたしますので、お気軽にお申し付けください。

Output

Short answers first: no, output is not lower because you're a non‑member, and no, you are not penalised by time — PowerX bills by kWh charged, not by the clock. Tapering as SOC rises is normal behaviour.

**1) Membership / plan does not affect speed**
Charging output is identical for PowerX First members and general (free) users, and it is the same across the Economy / Regular / Premium menus. The menus differ only in renewable‑energy ratio and unit price, not speed (ja/runbooks/compatibility.md:139, ja/runbooks/charging-use.md:27, ja/runbooks/charging-use.md:234). There are documented cases where a customer believed joining/changing status changed their output — it did not; output was being auto‑limited by temperature and the vehicle's acceptance state (ja/runbooks/charging-troubleshooting.md:196, ja/runbooks/charging-use.md:46).

**2) Billing is per kWh, so low output is not a time penalty**
Fees are pay‑as‑you‑go on the energy actually charged, not on elapsed time (ja/runbooks/billing.md:27, ja/runbooks/billing.md:193). Even within a 30‑minute booking, you pay only the kWh delivered (ja/runbooks/billing.md:244). So a slow session costs the same per kWh as a fast one — you just get less energy in the slot (ja/runbooks/charging-troubleshooting.md:460).
One genuine time‑related difference: general users can reserve from 30 minutes before use with slots up to 30 minutes, while PowerX First allows booking up to 3 days ahead with slots up to 75 minutes (ja/runbooks/charging-use.md:248). So if output is low, a general user's slot may end before reaching the target SOC — that is a slot‑length issue, not a billing penalty.

**3) What the "150kW" figure actually means**
Max output is 150kW on a single port, and 120kW when two ports charge two cars simultaneously (ja/public-help/articles/23123162280473.md:20). Some stations are currently capped at 120kW, with a staged upgrade to 150kW at all sites (en/reference/membership.md:195). Actual output varies with usage conditions, environment, and the vehicle's receiving capacity (ja/public-help/articles/23123162280473.md:21).

**4) Why 55–90kW, gradual decline, or drop near full is usually normal**
- Ambient temperature and the charger's internal temperature trigger automatic output limiting (ja/public-help/articles/23459356662809.md:20).
- The charger only delivers what the car asks for, so many models never reach 150kW, and cold batteries accept less (ja/runbooks/charging-use.md:145, ja/runbooks/charging-use.md:126).
- Output falling as SOC rises is standard vehicle behaviour, not a charger fault (ja/runbooks/charging-troubleshooting.md:460).
- A "135kW at another network" comparison is not directly comparable, since the peak depends on the car's acceptance curve, battery temperature and SOC at that moment.

**5) What to check on your side**
- The station's listed max output in the app, and whether the adjacent connector is in use (2‑port = 120kW cap).
- Any diagnostic/error code shown in the app — if one appears, contact support (ja/public-help/articles/23459247986585.md:20).
- Connector fully seated and locked, shift in P, vehicle power OFF, and no charge timer / charge‑limit (SOC cap) setting active.
- Retry from "Charge again" in the app, and try the opposite charger (ja/runbooks/charging-troubleshooting.md:504, ja/runbooks/charging-troubleshooting.md:196).
- Battery state: charging immediately after driving (warm battery) usually gives higher output; a cold or already‑high battery will be slower.

**6) When to report it as abnormal**
Fluctuating output (e.g. 81 → 60 → 54kW, or brief drops to zero) can be vehicle‑side, but it is worth logging: in a comparable IONIQ 5 case, support checked the session by customer ID, found no device error, and escalated internally for review (ja/runbooks/charging-troubleshooting.md:504). To let us check the specific session, please send: vehicle model, your user ID, date/time, station, left/right unit, LED colour, any error/diagnostic code, what the app and the car's display showed, and whether re‑charging worked.

Note: the workspace confirms per‑kWh rates of ¥65/¥70/¥75 (Economy/Regular/Premium) for general users and from ¥45/kWh for First (ja/runbooks/charging-use.md:105, ja/runbooks/charging-use.md:248); it does not contain a station‑by‑station list of which sites are still limited to 120kW, so please check the specific station page in the app for that.

Output

充電出力のご相談、承知いたしました。結論から申し上げます。

1. 出力が低いのは非会員だから、ではありません
最大出力は会員種別（PowerX First／一般）やプランによる差はなく、1口利用で最大150kW、2口（2台同時）利用で最大120kWです（/sources/ja/runbooks/charging-use.md:27、/sources/ja/public-help/articles/23123162280473.md:20）。Firstのご特典は「充電単価の割引」「3日前からのご予約」「予約枠が最大75分（一般会員は最大30分）」で、充電速度自体は同じです（/sources/ja/runbooks/charging-use.md:248）。

2. 仕様どおりでも、最大出力に達しないことはあります
公式にも「使用条件や環境要因、車両の受電容量等によって出力容量は変化する」と案内しています（/sources/ja/public-help/articles/23123162280473.md:21）。具体的には、外気温・充電器本体の温度による自動出力制限、車両が受け入れられる電力、SOCの上昇が要因です（/sources/ja/runbooks/charging-troubleshooting.md:460、/sources/ja/runbooks/charging-use.md:145）。
・SOCが上がるにつれ出力が下がるのは一般的な挙動で、満充電が近づいて落ちるのは正常側です。
・気温が低い時期は出力が上がりにくい傾向があります。
・なお、一部ステーションでは最大出力を120kWに制限しており、順次150kWへアップデート予定とされています（/sources/ja/public-help/articles/40049220868505.md:22）。

3. 料金面での「不利」について
PowerXは時間ではなく充電した電力量（kWh）に対する従量課金制です（/sources/ja/runbooks/billing.md:27、/sources/ja/runbooks/billing.md:193）。30分枠のご予約でも15分で終了すれば、料金は15分間の充電電力量×単価です（/sources/ja/runbooks/billing.md:244）。したがって、出力が低いこと自体で時間分だけ請求が増えて不利になることはありません。
一方で、予約枠内に充電できる電力量は出力に左右されますので、まとめて充電されたい場合は最大75分枠をご利用いただけるFirstが時間的なゆとりでは有利になり得ます。

4. 他社で135kWとの比較について
車両の受電特性（受電カーブ）、開始時SOC、バッテリー温度、外気温、同時利用の有無が毎回同じとは限らないため、同一条件での比較にはなりにくい点をご案内しています。

5. 異常かどうかの切り分けで確認いただきたい点
・2台同時（2口）利用ではなかったか、当該ステーションの最大出力表示
・充電開始時SOCと、低下が始まったSOC
・外気温、および連続利用直後ではなかったか（充電ガン過熱でLEDが黄色点灯し、10〜15分のクールダウン後に再開できるケースがあります／/sources/ja/runbooks/reservations.md:183、/sources/ja/runbooks/reservations.md:199）
・車両側の受電容量・バッテリー温度、充電制限やタイマー等の車両設定、電源OFFの状態
・アップダウンや一時的な出力ゼロを繰り返す場合は、車両側起因の可能性もありますが、IDで機器エラーの有無を確認し社内で連携いたします（/sources/ja/runbooks/charging-troubleshooting.md:504）

6. 個別調査をご希望の場合
以下の情報をご提供いただければ、充電状況の詳細を確認のうえ社内連携いたします：ユーザーID、車種・年式、充電日時、拠点、充電器の左右、LEDの色、エラーコード、アプリ／車内表示の内容、再充電できたか。
※現時点で、原因確定や機器改善の完了をお約束するものではありません。調査・連携のご対応となります。
