Description

Technical Field

[0001] This application relates to the fields of power management and power design technology, and in particular to an uninterruptible power supply for information service equipment. Background Technology

[0002] Information service equipment provides high-speed computing and storage capabilities to the system and can be applied in various scenarios. When the information service equipment is running, the computing services running in the system need to be unaffected by changes in working status, and continuously, stably, and uninterruptedly provide computing and storage services. Once the power is lost, all computing services will terminate, resulting in data loss. In the power management design of existing information service equipment, some rely solely on external power supply, and the equipment will stop working once the power is lost; some information service equipment is equipped with backup batteries, which can rely on battery power after an external power failure, but there is a time delay when switching to battery operation, which affects the operation of the equipment and may lead to the termination of equipment services and data loss.

[0023] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0024] This application provides an uninterruptible power supply for an information service device, such as... Figure 1 As shown, it includes:

[0025] The self-powered battery pack is equipped with a power level indicator to facilitate battery replacement or switching. In some embodiments, the self-powered battery pack includes at least two sets of self-powered batteries, which are respectively connected to the system backplane. The at least two sets of self-powered batteries are divided into primary and backup batteries, and individual batteries can be replaced according to the power level indicator.

[0026] An AC-to-DC adapter converts an external power input into DC power. The AC-to-DC adapter is connected to an external backup battery holder and a system backplane. The system backplane is connected to the self-powered battery pack.

[0027] An external backup battery holder, containing the same self-powered battery pack, is connected to the system backplane as an external power source. The external backup battery holder contains the same batteries as the device; it can be removed and installed separately for use with the device, or it can be used as a whole to directly power the device as an external emergency power source.

[0028] A power management board, connected to the system backplane, is used to detect the battery parameters of the self-powered battery pack. The two power management boards serve as primary and backup for each other.

[0029] In some embodiments, such as Figure 2 As shown, the external backup battery holder and AC-to-DC adapter are respectively connected to an electromagnetic compatibility filter circuit and a voltage isolation conversion circuit, and then connected to a power switching module to select between the two circuits. In a specific example, the two power inputs output 24V DC through the power switching module to supply the device's power conversion unit, charging management, battery management unit, and battery metering modules.

[0030] In some embodiments, a voltage conversion module is further included, which is connected to the power switching module and is used to perform voltage conversion output after selecting the two circuits.

[0031] In some embodiments, such as Figure 2As shown, the voltage isolation conversion circuits for both paths are connected to the current and voltage monitoring module to monitor the voltage and current of the two paths and output the voltage and current to the power supply main control management module.

[0032] In some embodiments, a switch module is also included, connected to the power main control management module, to turn the uninterruptible power supply on or off based on the power switch.

[0033] In some embodiments, such as Figure 2 As shown, the power control management module is connected to the battery management unit and the charging management module;

[0034] The charging management module is connected to the isolation filtering module;

[0035] The battery management unit is connected to the isolation filter module via two metering modules.

[0036] The isolation filtering module is connected to at least two sets of self-powered batteries.

[0037] In a specific example, the charging management module controls the charging method of the battery pack by the external power supply. Charging typically consists of four stages, which can be categorized chronologically as trickle charging, constant current charging, constant voltage charging, and charging termination. The charging time is the sum of the times for all four stages. The sum of the times for the first and fourth stages is less than 1% of the total charging time, and the charging time is approximately equal to the sum of the times for the second and third stages. Generally, when the battery capacity is fixed, the total charging time can be estimated using the formula Q = I × T, where Q is the nominal capacity of the battery in Ah, T is the total charging time in hours, and I is the charging current in A.

[0038] In the specific example, after the device is powered on, the device's power management system determines whether there is external power supply. If there is external power supply, it is used, and the battery is checked simultaneously. First, it checks whether battery 1 is installed on the device. If battery 1 is not detected (marked P1), the battery is not charged. If battery 1 is detected, its power level is recorded. Then, it checks the power level of battery 2. If battery 2 is not detected (marked P2), the battery is not charged. If battery 2 is detected, its power level is recorded. The power levels of battery 1 and battery 2 are compared. If the power level of battery 1 is greater than that of battery 2, battery 2 is charged first, and its power level is checked periodically. If the power level of battery 2 is greater than that of battery 1, battery 1 is charged first, and its power level is checked periodically, and this process is repeated.

[0039] If there is no external power supply, battery power is used. First, the power of the two batteries is detected and the power of battery 1 and battery 2 are recorded respectively. The power of battery 1 and battery 2 are compared. If the power of battery 1 is greater than that of battery 2, battery 1 is discharged; if the power of battery 2 is greater than that of battery 1, battery 2 is discharged. At the same time, the device power management system needs to check whether there is external power supply at any time.

[0040] The embodiments of this application design a dual-battery backup mode to reduce the impact of single-point failures and improve overall redundancy reliability. In the case of two battery packs, the two battery packs can be used for hot backup discharge in a primary / backup manner.
