1.  日产中国介绍

Nissan日产汽车作为全球汽车主流品牌之一，日本三大车企之一，其生产的产品质量管理体系完善，品质稳定，研发实力强劲，产品测试标准在行业内要求颇高，因其在中国合资的生产销售起步较早，在国内合资汽车品牌中保持良好的成绩，随着近年来汽车新四化的概念提出（智能化、电动化、网联化、轻量化），电子零部件在整车构造中的使用率快速提升，加之中国区域的供应链非常庞大，这为日产汽车的零部件供应商产品质量管控提出了新的挑战。

作为一家全方位提供汽车电子零部件检测认证的第三方实验室，NEI能仪检测从2013年开始，就重点投资到汽车电子EMC领域，特别是日产汽车的供应链检测服务，从日产的技术标准解读，到供应商现场培训，从测试整改的技术指导，到多次邀请日产EMC专家进行探讨，通过多个测试项目的交流和沟通，NEI技术团队能够深入掌握日产的EMC测试要求，并且公司重点扩充了日产EMC测试所要求的全套设备，在第三方实验室中，NEI能仪检测的专业服务能力和硬件设备能力均排在前列。
