本应用是专用于智能锂电池管理系统的工具软件。App使用低功耗蓝牙（BLE4.0）与电池管理系统（BMS）建立连接，可通过手机设备读取电池信息。 SmarTEC-BMS可支持两个系列的智能电池，定义为A系列和B系列。其中B系列比A系列多出一页单体电池电压信息。App启动后，系统打开蓝牙并搜索名称为 “SmartBat”的BLE设备，过滤并列表显示指定的电池设备名称和对应的RSSI值。 点击设备进入设备信息页面，第一页显示电池的电压(Voltage)、电流(AverageCurrent)、SOC、电池充放电状态(StateOfBattery)、循环次数等信息(CycleCount)。 向左滑动显示下一页信息，第二页显示电池温度(Temperature)、设计容量(DesignCapacity)、剩余容量(RemainingCapacity)、满充容量(FullChargeCapacity)、可用时间(AverageTimeToEmpty)、充满时间(AverageTimeToFull)、制造日期(Manufacture Date)、电池串号(Serial Number)等信息。 如果是A系列设备第三页信息为公司网站，B系列设备显示电池单体电压(CellVoltage)信息。 B系列设备第四页信息为公司网站，A系列设备无第四页信息。
