Description

Technical Field

[0001] The present application relates to the technical field of communication power supply, and in particular to a device for controlling power supply by using battery capacity and voltage. Background Art

[0002] At wireless sites, batteries provide power after a mains power outage. Due to limited battery capacity and backup time, if the mains power doesn't return after a period of battery operation, secondary loads (such as transmission equipment) must be disconnected to extend the life of the primary loads. This ensures continued operation of the primary loads. This is known as a "primary power outage." If the battery continues to discharge and consume power, and the battery charge drops to a certain level, all loads must be disconnected to prevent damage from over-discharge, and the entire base station must be taken out of service. This is known as a "secondary power outage."

[0003] Existing methods for controlling primary and secondary battery power-down primarily rely on a primary power-down switch and secondary power-down quick-release switches to achieve different power-down periods based on demand. However, wireless stations are often unmanned, making it difficult for existing devices to automatically and accurately power down the system in unmanned environments. Existing electric vehicles, which primarily use lithium batteries, do not utilize switching power supplies but instead rely on multiple lithium battery packs. These control systems do not require secondary power-down and are therefore not suitable for the aforementioned primary and secondary power-down control methods.

[0004] Existing switching power supply systems primarily use battery voltage as a control value to control base station "primary power-off" and "secondary power-off." This standard is not applicable to lithium batteries. When lithium batteries use battery voltage as a control value to control power-off, base station loads are quickly "secondarily powered off" after the "primary power-off." This limits the backup power duration of critical loads and fails to meet the power supply time requirements for important equipment.

[0005] To address this issue, some base stations currently artificially increase the voltage during the "primary power-off" phase to extend the time between the primary and secondary power-off events, ensuring the power supply duration for critical user loads. However, this results in an earlier primary power-off event. Without changing the total battery backup capacity, the backup duration for conventional loads contracted by the operator may not be met, impacting user experience. This also results in underutilization of the battery backup energy, hindering lithium battery capacity maintenance and accelerating capacity degradation. Utility Model Content

[0056] The working principle of the device for controlling the power supply by the battery capacity and voltage provided in the application is as follows:

[0057] Normal power supply stage:

[0058] The mains (or standby diesel generator, switched by double alternating current input circuit breaker interlocking) is input through the alternating current power distribution unit, and the alternating current is converted into direct current through multiple switching power supply rectifier modules in the switching power supply module unit. The generated direct current is divided into two paths, one of which supplies the direct current power distribution unit, and the other of which supplies the bidirectional DCDC module unit. The unit intelligently charges the connected battery (constant current / constant voltage, etc.). The monitoring unit collects information such as alternating current input state, rectifier module state, direct current power distribution unit branch load current, and battery state (through bidirectional DCDC module) in real time through RS485, CAN, and other communication modes.

[0059] Battery power supply stage:

[0060] After the mains and standby diesel generator power supply are interrupted, the bidirectional DCDC module unit immediately switches the working mode from charging mode to discharging mode, and the electrical energy stored in the battery is boosted through the bidirectional DCDC module to output direct current. The direct current is reversely supplied to the direct current bus of the switching power supply module unit, and then supplied to the direct current power distribution unit, and the intelligent circuit breaker continues to supply power to the connected load.

[0061] Intelligent hierarchical power-down control:

[0062] The monitoring unit continuously and real-time acquires the key data of the battery through the bidirectional DCDC module: battery capacity (SOC) and battery voltage.

[0063] Primary power-down trigger (part of the secondary load is disconnected): When the monitoring unit determines that the battery capacity (SOC) and battery voltage meet the primary power-down condition, it sends a command to the DC power distribution unit through CAN communication. The intelligent circuit breaker (such as 63A, 10A) inside the DC power distribution unit is disconnected, cutting off the power supply of part of the secondary load. At this time, the important load continues to be powered by the battery;

[0064] Secondary power-down trigger (part of the secondary load or important load is disconnected): When the battery continues to discharge, the monitoring unit determines that the battery capacity (SOC) and battery voltage meet the secondary power-down condition, and again instructs the DC power distribution unit to disconnect part of the load (which can include part of the important load) through CAN communication.

[0065] By analogy, more power-down conditions can be set to gradually power down the load.

[0066] Note that all features disclosed in this specification (including any accompanying claims, abstract and drawings) can be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is only one example of a generic series of equivalent or similar features. Further, where used, further, more, further more and even more are simple continuations of the preceding embodiment and are not used to indicate any particular emphasis. The combination of the preceding embodiment with the combination of the further, more, further more or even more trailing features forms another embodiment.

[0067] In the implementation of functions and steps, the corresponding functions and steps in each embodiment can also occur in a different order from that shown. For example, two consecutive functions and steps can actually be executed or implemented substantially in parallel, or they can sometimes be executed or implemented in reverse order, depending on the functions involved.

[0068] Although the present application has been described in detail above with specific reference to the preferred embodiments, it is obvious that modifications and improvements can be made to the application without departing from the spirit and scope of the application. Therefore, these modifications and improvements made on the basis of the application are also within the scope of the application claimed.
