Problems solved by technology

[0002] The backup power supply of the outdoor power supply base station is generally composed of battery packs connected in series, and the backup power supply, maintenance, replacement, etc. are performed with the battery pack as a unit. The energy storage capacity of the battery cannot be fully utilized, the abnormality of one or more battery cells will affect the output of the overall battery pack, the battery will fail early, and the service life will be shortened. On the other hand, the investment cost is high. The consistency of the battery is very high. Once a certain battery is abnormal or fails, it needs to be repaired or replace the entire battery pack, which means that huge purchase costs, maintenance costs and labor costs are required.
[0003] In addition, the batteries used in outdoor base stations work in harsh environments, and are exposed to high temperatures for a long time. Improper use can easily degrade the performance of the batteries and cause damage. The service life is greatly shortened
The traditional outdoor power supply base station lacks sufficient and scientific management measures for battery charging and discharging, and cannot scientifically evaluate the battery life of the base station through the charging capacity of the battery. It is prone to emergencies, and there is a risk of power loss and power failure, and the repair is not timely enough. The repair time is long and difficult, resulting in immeasurable potential economic losses

The CPU module is respectively connected with the 12V circuit breaker and the acquisition module for storage, data analysis and processing, charge and discharge control, etc. The 48V circuit breaker is connected with the MOS power module 1, MOS power module 2, energy storage inductor, the 12V circuit breaker and the acquisition module in turn. The modules are connected in series, and the drain of the MOS power module 1 is connected in parallel with the source...

specific Embodiment approach 2

[0032]Specific embodiment 2: This implementation method is based on specific embodiment 1. As a supplement to specific embodiment 1, an implementation method of a battery management device for an outdoor power supply base station can improve the energy storage capacity of the battery and accurately measure the charge and discharge capacity of the battery. , to scientifically evaluate the battery life and performance of the battery, specifically as follows:

[0033] 12V batteries are charged in parallel, and each 12V battery can be fully charged, giving full play to the energy storage capacity of each battery, while avoiding overcharging and undercharging.

[0034] When performing a checking capacity discharge test, each parallel-connected 12V battery is boosted and discharged, and the actual capacity of the battery can be accurately calculated through the discharge stop voltage and current of each 12V battery collected by the acquisition module, and then the capacity of each ba...

specific Embodiment approach 3

[0035] Specific implementation mode three: a battery management method for an outdoor power supply base station provided by the present invention, the specific steps are as follows:

[0036] S1: Collect the voltage and current of each 12V battery, the current at the 12V circuit breaker terminal, and the voltage and current at the 48V circuit breaker terminal;

[0037] S2: When it is judged that any battery cell voltage module is lower than or equal to the first threshold, the output PWM1 signal of MOS power module 1 starts charging the battery pack, and the signal forms a closed-loop control with the real-time collected voltage / current of the 12V circuit breaker terminal Realize constant voltage / constant current charging; and output PWM2 signal of MOS power module 2 so that IGBT2 of MOS power module 2 is in closed state;

[0038] S3: When judging that the voltage at the 48V circuit breaker terminal is lower than or equal to the second threshold, output the PWM2 signal of the M...

Abstract

The invention discloses an outdoor power supply base station storage battery management apparatus and method. The outdoor power supply base station storage battery management apparatus includes a CPUmodule, a 48V breaker, an MOS power module 1, an MOS power module 2, a storage inductor, a 12V breaker, and an acquisition module. Compared with the prior art, the outdoor power supply base station storage battery management apparatus converts a traditional mode in which storage battery elevators are connected in series to form a storage battery pack into a parallel connection mode taking a 12V storage battery as a unit, thus fully improving the energy storage capacity of each storage battery, greatly saving the input cost, improving the utilization rate of the storage battery, effectively prolonging the service life of the storage battery, and avoiding damaging the performance of the storage battery by charging at the outdoor high temperature, and carries out charging by using a pluralityof program-controlled charging modes, so that the uninterrupted output is realized during the discharging process, thus satisfying the power supply requirement of the base station.
