Abstract

The invention discloses a device for monitoring accumulator discharging, relating to a monitoring device for controlling the discharging current and discharging intensity of an accumulator. The device comprises an industrial personal computer (IPC), which is connected with a current given circuit and a voltage current temperature sampling circuit respectively; the current given circuit is connected with battery discharging device; the voltage current temperature sampling circuit is connected with the accumulator; and the IPC is connected with a man-machine interactive interface comprising a touch screen for setting parameters and a display screen for displaying data. The invention can provide a correct and proper comparing current and information for real-time measuring the capacity of the accumulator so as to ensure the realization of constant current discharge of the accumulator by controlling the current given circuit and the voltage current temperature sampling current through the IPC.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a storage battery discharge monitoring device. Background technique [0002] Batteries are widely used in important departments such as electric power and communications to provide uninterrupted power supply for equipment such as protection, control, communications, and computers. Therefore, it is very important whether the actual capacity of the battery is normal. For this reason, it is necessary to conduct regular charge and discharge tests on the battery. [0003] Now the battery discharge test mainly adopts the constant current discharge mode. In order to ensure the constant discharge current, it is extremely critical to provide a constant and appropriate comparison current. The comparison current and discharge current pass through the comparator and then through a series of components to ensure the discharge. To keep the current constant, in order to prevent the battery from over-disch...
