Description

Technical Field

[0001] This application relates to the technical field of on-line quality monitoring of lithium batteries, and particularly relates to a method, device and storage medium for on-line quality monitoring of lithium batteries for communication base stations. Background Art

[0002] The power supply system of wireless sites (base stations) usually uses commercial power as the main power supply and is equipped with a storage battery as a backup power supply. Commercial power provides stable power support for base station equipment under normal circumstances to ensure its daily operation; while the storage battery quickly switches and provides power when the commercial power is interrupted, and the storage battery supplies power to the base station equipment through a switching power supply to ensure the continuous operation of the base station equipment during the fault period.

[0003] With the increase of the usage time and frequency, the performance of the storage battery deteriorates continuously. It is of great significance to detect and evaluate the quality and performance of the battery in a timely, accurate and continuous manner for guiding maintenance, updating and scrapping disposal to ensure the backup power capacity of the base station.

[0004] When the lithium battery for backup power is put into the network, various indicators of the three parts of the battery system, BMS and platform access will be detected to ensure compliance with relevant standards and requirements. Generally, a sampling inspection method is adopted to extract samples for inspection from various product models and specifications, and the inspection is carried out by a professional laboratory. The method of network access inspection has the advantages of comprehensive inspection indicators and accurate inspection methods, but also has the disadvantages of insufficient coverage and inability to conduct continuous monitoring after network access.

[0005] After the lithium battery for backup power is put into the network, it is generally monitored and managed through the BMS (Battery Management System) provided by each battery manufacturer, and at the same time, it is combined with on-site inspection and detection by operation and maintenance personnel. The BMS generally has the following functions: 1. Real-time monitoring of battery voltage, current, temperature and other states to provide battery protection; 2. Preventing the battery from overcharging and over-discharging to extend the service life of the battery; 3. Evaluating the working state of the battery, calculating the state of charge (SOC) and state of health (SOH) of the battery, and reporting the degree of battery deterioration and the remaining capacity state; 4. Reporting the operation state to external devices, communicating with other systems or platforms to realize data transmission and management.

[0006] In actual operation and maintenance work, the backup power supply guarantee work is of top priority. The state and performance of the lithium battery for backup power directly determine whether the backup power supply duration after a power outage can meet the standard, which is crucial for ensuring the normal communication ability of the base station.

[0007] At present, there are the following difficulties in the maintenance and guarantee work of the lithium battery for backup power: 1. Currently, related enterprises in the communication industry generally have their own detection and evaluation methods for backup batteries, which stipulate key items for product quality inspection, detection requirements, product quality judgment criteria, etc. Only products that meet the requirements can pass the network access detection of tender projects. Such methods generally require sending samples to a laboratory for testing. Although they are relatively accurate, they cannot be continuously implemented during subsequent use, and the sampling and sending mode has insufficient coverage. 2. There are a large number of base stations, which are widely distributed geographically and involve complex terrains such as mountainous areas. It is difficult to verify them one by one on-site, and timeliness cannot be guaranteed. 3. The method of discharge testing has high accuracy, but it cannot be carried out on a large scale in batches. 4. Different battery manufacturers use different technical methods for the BMS to evaluate the remaining capacity, resulting in differences and inconsistencies. 5. Long-term and frequent power outages from the mains cause the battery to be overcharged and discharged cyclically, resulting in serious performance loss. 6. Different usage environments, such as high temperature, low temperature and other environmental factors, lead to differences between the theoretical performance and the actual performance of the battery.

The specific rules are as follows: S21. Obtain the asset service life score, with a weight of 10 points (i.e., the full score of this item is 10 points).

[0051] Calculation method: (1) The calculation of the asset service life is the current time minus the battery activation time.

[0052] (2) When the asset service life is greater than or equal to 6 years, the score is 0.

[0053] (3) When the asset service life is less than 6 years, the score is calculated as (6 - asset service life) / 6 × 10.

[0054] Asset service life = current time (2025-02-26) - 2020-08-01 = 4.58 (years) Since the asset service life of the battery to be tested is less than 6 years, the score of this item is calculated as: = (6 - 4.58) / 6 × 10 = 2.37 S22. Obtain the remaining battery capacity score, with a weight of 10 points.

[0055] Calculation method: (1) The remaining battery capacity takes the maximum value of the performance values in the last three days.

[0056] (2) The calculation of the battery retention rate is the remaining battery capacity divided by the battery rated capacity.

[0057] (3) When the battery retention rate is greater than 1.1 or less than 0, the score is 0.

[0058] (4) When the battery retention rate is between 1 and 1.1, the score is 10.

[0059] (5) When the battery retention rate is less than 1, the score is calculated as the battery retention rate × 10.

[0060] Retention rate of the battery under test = 98.09 AH / 100 AH = 0.98 Since the retention rate of the battery under test is less than 1, the score calculation for this item = 0.98 × 10 = 9.8.
