摘 要
目前全球能源及生态环境正在面临严峻考验，节能减排成为了当前中国能源与环境问题的关键措施，同时随着燃油价格的不断上涨，新能源汽车的发展得到了飞速的发展，新能源汽车在一定程度上解决了传统燃料汽车的环境污染问题，同时也帮助缓解了能源短缺和碳排放的问题。截止到20年，中国区域内的新能源汽车销量占全球新能源汽车销量的41%，对于新能源汽车的认可度和普及度都在不断提高，对于新能源汽车信息的了解和普及也成为了当前的主要需求，借助线上平台及手机应用端开发的汽车介绍应用日益增多，例如人们所熟悉的汽车之家和懂车帝等平台，为用户提供了非常详细的汽车信息介绍，然而这些平台都需要下载对应的APP才可以实现使用。
结合目前对于新能源汽车需求的日益提升，为了提供更加专业的新能源汽车信息给到潜在消费者，此次服务平台的开发和设计基于小程序>微信小程序端来实现，小程序>微信小程序借助微信平台就可以实现小程序的应用，不需要额外下载应用且覆盖范围更加广阔，通过借助新能源汽车信息平台为用户提供针对新能源汽车的基本信息，包括目前比较火的新能源汽车品牌、车型介绍以及汽车周边等信息，通过评估推送新车上市信息，同时对于新能源周边产品可以通过平台实现在线购买，考虑到数据的安全性以及个人信息的隐私性，此次系统平台在登录环节采用了MD5加密的设置来隐藏用户密码以及购买记录等隐私信息，通过小程序>微信小程序的开发和设计，对于新能源汽车信息进行针对性的介绍便于用户信息的获取以及周边商品的购买。

Abstract
At present, the global energy and ecological environment are facing a severe test. Energy conservation and emission reduction have become the key measure for China’s energy and environmental problems. At the same time, with the rising fuel prices, the development of new energy vehicles has been rapid. The recognition and popularity of new energy vehicles have been increasing, and the understanding and popularization of new energy vehicle information has also become the current main demand. With the help of online platforms and mobile phone applications, more and more vehicle introduction applications have been developed, such as the familiar platforms of Autohome and Autocar, It provides users with very detailed vehicle information, but these platforms can only be used after downloading the corresponding APP.
In combination with the increasing demand for new energy vehicles at present, in order to provide more professional new energy vehicle information to potential consumers, the development and design of the service platform is based on the WeChat applet terminal. WeChat applet can achieve small program applications with the help of the WeChat platform, without additional downloading of applications and covering a wider range, By using the new energy vehicle information platform to provide users with basic information about new energy vehicles, including the currently popular new energy vehicle brands, model introductions, car surroundings and other information, and by evaluating and pushing new vehicle listing information, online purchase of new energy peripheral products can be realized through the platform. Considering the security of data and the privacy of personal information, The system platform uses MD5 encryption settings to hide user passwords, purchase records and other private information during the login phase. Through the development and design of WeChat applet, targeted introduction of new energy vehicle information is made to facilitate the acquisition of user information and the purchase of surrounding goods.
