本頁整理了 IEC 61851:2017 的官方文件、目前狀態以及常見相關認證或評估機構，便於快速理解要求與落地路徑。
Charging Modes 1-4
Defines four standardized charging modes — from basic AC household socket charging (Mode 1) through DC fast charging with external charger communication (Mode 4) — providing a common framework worldwide.
Safety Protection
Specifies comprehensive electrical safety requirements for EV supply equipment including over-current protection, ground fault detection, and control pilot signaling to prevent hazardous conditions.
Connector & Communication
Establishes requirements for EV couplers, connectors, and the control pilot (CP) communication protocol between the vehicle and charging station for safe and interoperable charging sessions.
list_alt Key Technical Areas
- Charging Mode 1 — AC basic (household socket, limited current)
- Charging Mode 2 — AC with in-cable control and protection device (IC-CPD)
- Charging Mode 3 — AC with dedicated EV supply equipment (EVSE)
- Charging Mode 4 — DC with external charger
- Control pilot (CP) signal specifications and states
- EV supply equipment electrical safety requirements
- Rated supply voltage up to 1000V AC / 1500V DC
- Environmental and mechanical requirements for charging equipment
誰需要合規？
Manufacturers of EV supply equipment (EVSE / charging stations), EV manufacturers integrating on-board chargers, charging network operators, and electrical installation contractors. Required for CE marking in the EU and referenced by national electrical codes globally.
關鍵要求
Charging Mode Classification
EV supply equipment must be designed and tested according to its intended charging mode (1-4). Each mode has specific requirements for maximum current, voltage, control pilot signaling, and protection measures.
Electrical Safety & Protection
Implement over-current protection, residual current detection (Type B RCD for DC fault currents), protective earthing, and isolation monitoring. Ensure de-energization of connectors before they can be physically disconnected.
Control Pilot Communication
Implement the control pilot (CP) signaling protocol using a 1 kHz PWM signal to communicate between the EVSE and vehicle. Signal states control charging current limits, ventilation requirements, and connection status.
Environmental & Mechanical Requirements
EV supply equipment must meet specified IP ratings, operating temperature ranges, impact resistance, UV resistance (for outdoor units), and material flammability requirements appropriate to its intended installation environment.
Connector & Coupler Safety
EV couplers and connectors must meet requirements for mechanical strength, contact resistance, temperature rise, insertion/withdrawal forces, and locking mechanisms to prevent accidental disconnection during charging.
實施路線圖
定義電動汽車傳導充電系統範圍
識別 IEC 61851:2017 覆蓋的產品、服務、場所、系統、團隊、司法轄區和相關方。確認責任人、邊界、適用義務、文件和證據期望，範圍包括EV 供電設備額定值、充電模式、電氣安全、保護措施、控制導引功能、連接方式、標識、說明和接口要求。
評估差距並排列風險優先級
將當前實踐與預期的電動汽車傳導充電系統方法進行比較。審查設計要求、部件資格、電氣保護、EMC 協同、型式測試、安裝說明、標籤和變更控制，並按法律暴露、安全影響、客戶承諾、運營依賴以及審覈或市場準入準備度排列差距優先級。
實施控制和記錄
部署所需程序、技術控制、評審關口、培訓、供應商流程、報告路徑和運行記錄。維護技術文件、測試報告、原理圖、額定值、安全分析、安裝手冊、標籤、供應商記錄和生產控制證據作爲可追溯證據。
評審、審覈並改進
開展內部評審、管理報告、審覈、糾正措施和變更評估。當產品、服務、供應商、技術、法規、事件或相關方期望變化時刷新項目。

處罰與執行
No direct penalties from IEC. However, non-compliant charging equipment cannot obtain CE marking in the EU, UL listing in North America, or equivalent certifications in other markets. Non-compliant installations may violate national electrical codes, leading to fines, insurance voidance, and liability for electrical incidents.
常見問題解答
誰需要 IEC 61851:2017？
expand_more
IEC 61851:2017 最適用於電動汽車供電設備和充電基礎設施的製造商與運營方。具體範圍取決於產品、服務、司法轄區、客戶承諾，以及組織是否需要認證、符合性證據、監管準備或內部治理。
IEC 61851:2017 是否可認證？
expand_more
符合性通常通過產品測試、認證方案、市場準入文件和客戶資格審覈證明，而不是管理體系證書。
實施時應先關注什麼？
expand_more
先定義範圍和義務，再建立當前狀態差距評估。早期最重要的工作是確認責任、受影響資產或過程、風險準則、客戶或法律驅動因素，以及組織必須能夠提供的證據。
IEC 61851:2017 需要哪些證據？
expand_more
有用證據包括技術文件、測試報告、原理圖、額定值、安全分析、安裝手冊、標籤、供應商記錄和生產控制證據。證據應進行版本控制，能夠追溯到責任人，並關聯風險、義務、控制、決策和糾正措施。
項目應多久評審一次？
expand_more
應按計劃週期評審，並在產品、服務、供應商、運行環境、事件、客戶承諾或法規變化時評審。高風險領域應採用更頻繁的監控和管理報告。
