Storage battery performance detection device and method

Abstract

The invention relates to the technical field of storage battery performance detection, and discloses a storage battery performance detection device and method.The storage battery performance detection device comprises a protection box body, the protection box body is horizontally arranged, the top surface of the protection box body is open, an experiment plate is horizontally arranged in the protection box body, and limiting plates are vertically and fixedly arranged on the left side and the right side of the experiment plate; and a partition plate is vertically and fixedly arranged on the top surface of the experiment plate, a clamping mechanism is arranged above the experiment plate, a damping mechanism is arranged below the experiment plate, and the clamping mechanism comprises a clamping box body, two cushion blocks and two clamping plates. According to the storage battery performance detection device and method, the clamping mechanism is arranged so that the battery can have a good clamping effect during measurement, and the situation that the detection data is inaccurate due to the fact that the battery shakes in an external environment is prevented; and by arranging the damping mechanism, the experiment plate can provide a better damping effect during battery detection by utilizing rotation of a threaded column and deformation of a connecting spring II.

Description

technical field [0001] The invention relates to the technical field of battery performance detection, in particular to a device and method for battery performance detection. Background technique [0002] As the working power source of the power protection system, the reliability of the DC power supply system is related to the safety and stability of the power supply of the power grid system. As the core equipment of the DC power supply system, the battery provides timely protection power when the station AC fails, and maintains the reliable operation of the protection equipment of the power station and power distribution station. Therefore, the reliability of the battery is directly related to the power safety of the power system. Because the battery is in the floating charge state online for a long time, it is difficult to judge the performance of the battery, such as the decrease in capacity, the increase in internal resistance, and what is more, the empty connection of th...

Problems solved by technology

Because the battery is in the floating charging state online for a long time, it is difficult to judge the performance of the battery, such as the decrease in capacity, the increase in internal resistance, and what is more, the empty connection of the battery poles cannot be obtained in time. Once the battery needs to be put into use, due to the above The problem is that the battery pack cannot provide power for the power protection system, which loses its proper meaning, and the whole station will be in an unprotected state

At present, the only way to monitor the performance of the battery is to conduct a qualitative discharge test on the battery. In the existing experiment, the battery temperature needs to be monitored all the time, and the existing temperature measurement and monitoring of the battery is to insert a thermometer into the battery, and then Check and record the reading of the thermometer every once in a while, this method is very inconvenient to operate
