摘要
为了满足电池行业对充放电设备越来越复杂的测试需求,设计了一种基于物联网的智能电池测试系统,由下位机、中位机、上位机及物联网系统组成。充放电电路设计分为三相电压型PWM整流器和双向Buck/Boost DCDC变换器。系统具有以下特点:首先,系统在普通电池测试流程中加入公式编辑功能,用户可自定义变量控制设备运行和跳转,特殊任务如:直流内阻测试、模拟充电桩、BMS数据跳转等;其次,系统具有丰富的接口,可灵活扩展第三方设备,如步入式温箱,BMS可控电源,电池压力传感器等,不仅能获取第三方信息控制设备运行和跳转,还可以随电池测试任务调节第三方设备输出,实现智能控制;最后,系统接入物联网管理平台,运行信息汇总到云平台,通过移动应用及时呈现给用户。
In order to meet the increasingly complex testing requirements of the battery industry for charging and discharging equipment, an intelligent battery testing system based on the Internet of Things is designed, which consists of a charge and discharge circuit, an intermediate machine, a host computer and an Internet of Things system. The charge and discharge circuit design is divided into a three-phase voltage type PWM rectifier and a bidirectional Buck/Boost DCDC converter. The system has the following characteristics: First, the system adds a formula editing function in the normal battery test flow, the user can customize the variable to control device to run and switch, special tasks such as: DC internal resistance test, mimetic charging pile,BMS data control to switch, etc..Secondly, the system has a rich interface, which can flexibly extend third-party equipment, such as step-in thermostat, BMS controllable power supply, battery pressure sensor, etc. The system can not only obtain the thirdparty information to control device to run and switch, but also adjust the output of the third-party device with the battery test task to realize intelligent control. Finally, the system accesses the Internet of Things management platform, and the operation information is aggregated to the cloud platform, which is presented to users in time through mobile applications.
