北美电动车充电连接器标准介绍

电动车充电连接器北美认证标准

CSA C22.2 NO. 282-17 / UL 2251 4th Edition — Standard for Plugs, Receptacles, and Couplers for Electric Vehicles（电动车辆用插头、插座和连接器的标准）

电动车充电连接器结构要求

1. C22.2 No. 282 要求的端子接触顺序

7.2.1 The contact sequence during the connection process shall be: a) Grounding contact,

      b) Neutral contact N, if provided,

      c) Line contacts, AC or DC, and

      d) Control pilot contact, if provided.

The proximity contact or the connection switch contact, if any, shall make after the grounding contact and before or simultaneously with the control pilot contact. During disconnection, the order shall be reversed.

7.2.2 The neutral contact N shall make before or simultaneously with line contacts, and break after or simultaneously with line contacts.

2. C22.2 No. 282 对绝缘材料性能要求：

    Flammability（可燃性）

    Electrical properties（电性能）

    Thermal properties（热性能）

3. C22.2 No. 282 对外壳机械性能要求：

10.2.1 An enclosure shall have adequate strength and rigidity for its intended use. It shall not permit any increase in shock or fire hazard due to total or partial collapse with resulting reduction in spacings, loosening, or displacement of parts, or other serious defects. See the Impact Test, 34, the Crush Test, 35, and the Vehicle Drive Over Test, 36.

外壳应具有足够的强度和刚性，以满足其预期用途。它不应允许由于完全或部分坍塌而导致的间隔减小、部件松动或移位或其他严重缺陷导致的冲击或fi再危险的任何增加。见冲击试验，碾压试验，和车辆驾驶过载试验。

4. C22.2 No. 282 对外壳环境等级要求：

10.6.1 An enclosure shall be marked with one or more enclosure type designations indicating the environmental conditions for which it is intended in accordance with 56.12. The enclosure shall comply with the requirements applicable to the enclosure type number or numbers. See Enclosure Tests for Environmental Protection, 54.

根据56.12的规定，外壳应标有一个或多个外壳类型标识，表明其所针对的环境条件。外壳应符合适用于外壳型号的要求。见环境保护封闭式测试。

5. C22.2 No. 282 对Current-Carrying Parts 载流体的要求：

11.1 Except as noted in 11.2 and 11.3, a current-carrying part shall be of silver, copper, or a copper alloy, or other material acceptable for the application. Plated iron or steel shall not be used for parts that are depended upon to carry current. Wire binding screws shall not be of iron or steel. Current carrying parts of contact shall comply with the requirements in Contacts, 18.

除11.2和11.3中另有说明外，载流部件应采用银、铜或铜合金或其他可接受的应用材料。不能使用镀铁或镀钢作为载流依靠的部件。捆扎钢丝的螺丝不能是铁或钢的。
