Storage battery surplus capacity monitoring device

The invention discloses a storage battery surplus capacity monitoring device which comprises a storage battery, an external circuit signal detecting module, a single-chip microcomputer module, a display module, an alarm module and a communication module. The storage battery is connected with the external circuit signal detecting module, and the single-chip microcomputer module is connected with the external circuit signal detecting module, the display module, the alarm module and the communication module. The surplus capacity is calculated according to storage battery data fed back by the external circuit signal detecting module through the single-chip microcomputer module and displayed on the display module in real time, the alarm module is started when the surplus capacity is lower than the preset capacity, and meanwhile the storage battery data is transmitted in real time through the communication module to achieve remote monitoring. 本发明公开了种蓄电池剩余容量的监测装置，包括蓄电池、外电路信号检测模块、单片机模块、显示模块、报警模块和通讯模块，蓄电池与外电路信号检测模块连接，
