Embodiment 1
[0018] The steps of the assembly method of the lead-acid battery of this embodiment are as follows:
[0019] For the same batch of batteries, use a multimeter or other testing equipment to detect and record the standing open circuit voltage of the battery, and remove the batteries that do not meet the requirements of the standing open circuit voltage; then connect the batteries in series to the charging and discharging equipment and connect them well Voltage acquisition line (it is better to use equipment with automatic data recording function, and ensure the acquisition accuracy of the equipment is 0.1~5s), set 0.33C rate discharge current to discharge the battery for the first time, and the discharge time is 3 hours. Record it The dynamic voltage of each battery at the end of discharge; after the first discharge, the battery that meets the requirements of the rated capacity will be matched for the first time according to the range of the dynamic voltage difference of the end of ...
