Embodiment example 1

[0070] Implementation case 1 (a total of three sets of batteries: one set of lead-acid, two sets of cascade batteries, corresponding to three or four types of mains):

[0071] Appropriate charging methods: sequential charging, continuous floating charging after the lead-acid battery is fully charged, optional floating charging or standby power shelving after the ladder lithium battery is fully charged, simultaneous discharge after the AC power failure, and cut off the discharge circuit when the battery is discharged to the secondary power-off voltage . When the mains is normal, the load is always powered by the charger.

Embodiment example 2

[0072] Implementation case 2 (a total of three sets of batteries, corresponding to new energy working conditions):

[0073] Suitable charging method: charging at the same time, because of the current limiting protection, overcharging will not occur. After being fully charged, it can be float charged according to requirements, and can be set aside for backup. When discharging, the ladder lithium battery is loaded and discharged.

Embodiment example 3

[0074] Implementation case 3 (a total of three sets of batteries: one set of lead-acid, two sets of cascaded batteries, corresponding to peak-shaving and valley-filling conditions):

[0075] Appropriate operation mode: charge at the same time when charging is required, disconnect the charger from the load when discharging is required, discharge with load by the step-by-step lithium battery, and reserve with lead-acid;

[0076] Valley power supply for 8 hours: start charging; flat power supply for 8 hours, keep fully charged; peak power supply battery discharge.

Abstract

The invention provides a matrix management system and method of multiple groups of batteries in a communication base station. The matrix management system comprises a load switch, a main battery management unit, a plurality of sub-battery management units and multiple groups of battery combination units, wherein each group of battery is correspondingly connected to each battery combination unit and each sub-battery management unit, each group of battery is connected to a charger via the battery combination unit, each sub-battery management unit is used for performing parameter sampling, running protection and charge-discharge state control and sending first running data to the main battery management unit, and the main battery management unit is used for receiving the first running data sent from the sub-battery management unit, storing and managing the first running data, controlling the running state of each group of battery, calculating a total charge state of the battery group andsending second data to a power environment system and a GPRS module. By the matrix management system, the problems of circulation, safety and reliability of multiple groups of batteries used in parallel in the communication base station can be solved.

Description

technical field [0001] The invention relates to the technical field of DC power supplies for power systems of communication base stations, in particular to a matrix management system and method for multiple sets of batteries in communication base stations. Background technique [0002] When the capacity of the power battery of an electric vehicle decays below 80% of the initial capacity, the battery needs to be replaced. With the rapid development of electric vehicles, more and more power batteries are retired from electric vehicles. If the remaining capacity can be effectively utilized, and its cascade utilization to the power supply system of the communication base station is used as a backup power supply, it will save energy and reduce pollution emissions. [0003] The DC power system of the communication base station power system usually uses lead-acid batteries as the backup power supply. The charging and discharging management of the lead-acid battery is completed by ...
