Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery detection tools, in particular to a lead-acid battery detection device. Background Art

[0002] As lead-acid batteries have been well applied in various fields, the batteries on the market currently rely on the accumulation of many years of production experience of battery companies, coupled with continuous scientific research and innovation, breaking through technical bottlenecks, and cooperating with market trends to produce batteries with high performance, economy, maintenance-saving and other characteristics that can meet customer needs; However, with the improvement of battery quality, the conventional means of evaluating its performance are taking more and more time, especially when evaluating based on traditional floating charge aging methods, the evaluation time of a type of lead-acid battery may take a year. It can be seen that the existing lead-acid battery performance detection efficiency is low;

[0003] In the prior art, when detecting the voltage of a lead-acid battery, a multimeter or a voltmeter is mainly used to detect the voltage of the lead-acid battery. However, since the voltage of the lead-acid battery should be within a certain range when it is charged, if the voltage is too low or too high, it may indicate that the battery has a fault or a charging problem. The lead-acid battery at room temperature may not be able to detect the voltage change. When detecting the capacity of the lead-acid battery, the capacity of the battery is generally detected by a discharge test. The discharge test requires the battery to be connected to an appropriate load and the amount of electricity discharged by the battery within a certain period of time is recorded. If the capacity of the battery is significantly lower than the nominal value, the battery may need to be replaced. The above-mentioned method for testing the lead-acid battery can only operate the charge and discharge state under a normal temperature environment, which is not convenient for simulating the charge and discharge performance and capacity detection operation of the lead-acid battery under different temperature environments, affecting the efficiency of the charge and discharge performance detection of the lead-acid battery.

[0044] Working principle: In this embodiment, the present invention also proposes a method for using a lead-acid battery detection device, comprising the following steps:

[0045] Step 1: First, open the cabinet door 2, place the lead-acid battery to be tested for charge and discharge on the top of the ventilation plate 13, then electrically connect each electrical appliance in the device to the control box 4 through wires, and connect it to the external power supply; then push the positioning beam 14 in the direction of the lead-acid battery to position the lead-acid battery on both sides.

[0046] Step 2, when the positioning beam 14 moves toward the lead-acid battery, the positioning assembly on the positioning beam 14 can automatically, in the state of the inclined surface at the bottom end of the positioning column 18, and with the cooperation of the spring 22 and the guide rod 21, enable the positioning column 18 after stopping to be clamped in the ventilation hole on the ventilation plate 13, and if the position of the positioning column 18 is between the two ventilation holes, the movable plate 16 can be longitudinally slid on the positioning beam 14 at this time.

[0047] Step three, when it is necessary to detect the charging speed of the lead-acid battery at room temperature, the electric push cylinder 10 is started to drive the sealing cover 7 connected to the connecting frame 9 to descend. When the sealing cover 7 descends, the pair of power plugs 32 in the power connection assembly can be electrically connected to the positive and negative poles of the lead-acid battery. Then, the lead-acid battery can be charged through the battery charging and discharging integrated machine 8, and the time required for charging is counted and the surface temperature of the battery during charging is detected and displayed. Generally, the charging temperature of the lead-acid battery at room temperature should not exceed 45°C; after the charging operation of the lead-acid battery at room temperature is completed, the discharge time test of the lead-acid battery at room temperature is then performed, and the voltage at the end of discharge is detected to judge the charging and discharging performance of the lead-acid battery detected at room temperature;

[0048] Step 4, after the performance test of the lead-acid battery at room temperature is completed, the lifting mechanism is started to drive the lifting platform 6 to descend, and when the lifting platform 6 descends, the electric push cylinder 10 will also drive the sealing cover 7 pressed on the top of the lead-acid battery to descend synchronously, and the sealing cover 7 is covered on the top of the test box 5, and then the refrigerator 26 is started to cool and cool the inside of the overhead slot of the lifting platform 6. At this time, the cold air inside the overhead slot blows on the lead-acid battery through the vents of the ventilation plate 13, so that the upper space of the test box 5 can be cooled and cooled, so that the lead-acid battery is in a low temperature environment, and then the lead-acid battery is charged again through the battery charging and discharging integrated machine 8, and the time required for charging the lead-acid battery in the low temperature environment is counted, and the battery surface temperature during charging in the low temperature environment is detected and displayed. After the charging operation of the lead-acid battery in the low temperature environment is completed, the discharge time consumption test of the lead-acid battery in the low temperature environment is then performed, and the voltage at the end of the discharge is detected to judge the charging and discharging performance of the lead-acid battery detected in the low temperature environment;

[0049] Step 5, after the lead-acid battery is tested under normal temperature, the cold air in the upper part of the test box 5 is quickly discharged by starting the open self-closing exhaust fan 11, and then the open self-closing exhaust fan 11 is closed, and then the space in the upper part of the test box 5 is heated by the heater 27, and the internal temperature of the test box 5 is raised to the range of 35-50 degrees Celsius, so as to facilitate the performance test of the lead-acid battery in the high temperature environment immediately after the low temperature environment monitoring; it is convenient to test the battery performance of the lead-acid battery under the condition of sudden temperature difference; when the lead-acid battery is in the high temperature environment, the lead-acid battery in the high temperature environment is charged again by the battery charging and discharging integrated machine 8, and the time consumption required for charging the lead-acid battery in the high temperature environment is counted, and the surface temperature of the battery during charging in the high temperature environment is detected and displayed. After the charging operation of the lead-acid battery in the high temperature environment is completed, the discharge time consumption test of the lead-acid battery in the high temperature environment is then performed, and the voltage at the end of the discharge is detected to judge the charging and discharging performance of the lead-acid battery detected in the high temperature environment;

[0050] Step six, after testing the battery charging and discharging performance of the lead-acid battery in normal temperature environment, low temperature environment, high temperature environment, and sudden changes in high and low temperature environment, start the electric push cylinder 10 to drive the sealing cover 7 to rise, so that the power connection component is disconnected from the tested lead-acid battery, and then start the lifting mechanism to drive the lifting platform 6 to rise out of the test box 5, and then unlock the positioning beam 14 for the lead-acid battery, and then remove the tested lead-acid battery from the ventilation plate 13.
