Description

technical field [0001] The invention relates to a method for remotely detecting the on-line capacity of a storage battery and a detection device used therefor. Background technique [0002] At present, most mobile communication base stations and repeaters (collectively referred to as stations) are equipped with battery packs as backup power during power outages. Due to the imbalance in the capacity of single cells in the battery pack, the capacity of the battery pack depends on the battery pack. The capacity of the single battery is outdated, and the longer the battery is used, the greater the imbalance. If the outdated battery in the battery pack cannot be detected and replaced in time, it will inevitably increase the risk of decommissioning of the base station or repeater after an AC power outage. Due to the wide distribution and large number of battery packs in base stations and repeaters, the traditional on-site capacity test has disadvantages such as laborious and time-...

Problems solved by technology

[0002] At present, most mobile communication base stations and repeaters (collectively referred to as stations) are equipped with battery packs as backup power during power outages. Due to the imbalance in the capacity of single cells in the battery pack, the capacity of the battery pack depends on the battery pack. The capacity of the single battery is outdated, and the longer the battery is used, the greater the imbalance. If the outdated battery in the battery pack cannot be detected and replaced in time, it will inevitably increase the risk of decommissioning of the base station or repeater after the AC power failure

Due to the wide distribution and large number of battery packs in base stations and repeaters, the traditional on-site capacity test has disadvantages such as laborious and time-consuming, low test accuracy, and long cycle time.

The disadvantages are as follows: when the battery internal resistance test is performed, the accuracy of the internal resistance test is likely to be poor. Since there is no standard for the qualified value of the battery capacity, the operator cannot locate the failed battery based on the detected value; when it is used for the constant current discharge capacity test , not only time-consuming and labor-intensive, the detection process is poor, but also unable to reflect the capacity of the battery under real load, it is difficult to use it in the inspection and general survey of the battery operating status of the base station; connection, and conduct capacity testing through the actual working load discharge), not only the working time is long, but also because the load current is changing all the time, the frequency of manual timing transcription of the discharge current is too low, which greatly reduces the test accuracy

[0003] To sum up, the traditional on-site capacity test cannot timely and accurately find outdated batteries in the battery pack, and cannot judge the capacity of the battery pack under real loads. Moreover, the efficiency of traditional on-site capacity testing is too low, and it is difficult for base stations or direct It is also unrealistic to test the discharge capacity of a large number of batteries in the station. If the outdated single batteries cannot be detected in time, the base station or repeater may be out of service at any time after the AC power failure
