Fig. 1 is a schematic structural diagram of an uninterruptible power supply according to an embodiment of the present invention. As shown in fig. 1, the uninterruptible power supply includes a main power unit 11 and an auxiliary power unit 12, and both the main power unit 11 and the auxiliary power unit 12 are powered by mains electricity; the auxiliary power unit 12 includes an auxiliary power supply 121, a charging pad 122, a battery 123, and a control device 124, a blower unit 125; the charging plate 122 is connected with the mains supply; the power supply mode of the auxiliary power supply 121 includes a charging pad power supply mode and a battery power supply mode; the battery 122 is charged by the charging plate 121; the fan unit 125 is used to dissipate heat from the auxiliary power unit 12.

Fig. 2 is a flowchart of an implementation of a power supply control method of an auxiliary power supply according to an embodiment of the present invention. As shown in fig. 2, the method for controlling the power supply of the auxiliary power source is applied to the uninterruptible power supply shown in fig. 1, and the method includes:
s210, when a fan unit of the uninterruptible power supply fails, alternately switching the power supply mode of the auxiliary power supply according to a preset switching mode; the preset switching mode is a switching mode which enables the electric quantity of the battery not to be lower than the preset overdischarge quantity.
In the embodiment of the invention, the fan failure of the uninterruptible power supply not only means the fan failure shutdown, but also means that the fan is in an operating state, and the fan cannot effectively dissipate heat due to insufficient rotating speed or software failure and the like. When detecting the fan trouble, for guaranteeing auxiliary power source's safe operation, switch over into the battery power supply mode at once, avoid the inside high temperature of uninterrupted power source.
In the embodiment of the invention, the charging panel power supply mode can be switched to charge the battery at any time before the battery is over-discharged. However, after the mode is switched to the charging panel power supply mode, in order to avoid the shutdown of the UPS due to the overhigh temperature, the mode should be switched to the battery power supply mode after a period of time.
In the embodiment of the invention, when the fan of the uninterrupted power supply fails, the method alternately switches the power supply mode of the auxiliary power supply according to a preset switching mode; the preset switching mode is a switching mode which enables the electric quantity of the battery to be not lower than the preset overdischarge quantity. Through use charging panel and battery when fan trouble in turn for auxiliary power source power supply, and when the charging panel was auxiliary power source power supply, the charging panel can charge to the battery again to under the prerequisite of guaranteeing the inside temperature of uninterrupted power source is too high, effectively avoid the battery to cross put.
In some embodiments, S220 may include: when the power supply mode of the auxiliary power supply is the battery power supply mode, after a preset time interval, switching the power supply mode of the auxiliary power supply from the battery power supply mode to a charging panel power supply mode; when the power supply mode of the auxiliary power supply is the charging panel power supply mode, after a first preset time, switching the power supply mode of the auxiliary power supply from the charging panel power supply mode to a battery power supply mode; and the discharge electric quantity of the battery in the preset time interval is not greater than the charge electric quantity of the battery in the first preset time.
In the embodiment of the invention, the preset time interval is less than or equal to the complete discharge time of the battery. The first preset time period may be a time period required for the battery to be fully charged, or a time period required for the temperature of the UPS to rise to the vicinity of the shutdown temperature, and is not limited herein.
In some embodiments, the auxiliary power supply control method further includes: and determining the ratio of the first preset time length to the preset time interval according to the ratio of the charging current of the charging plate to the current input to the auxiliary power supply.
In the embodiment of the invention, when the ratio of the charging current of the charging plate to the current input to the auxiliary power supply is k, the ratio of the first preset time interval to the preset time interval is more than or equal to 1/(k-1).
In some embodiments, determining the ratio of the first preset duration to the preset time interval according to the ratio of the charging current of the charging pad and the current input to the auxiliary power supply comprises: when the ratio of the charging current of the charging pad to the current input to the auxiliary power supply is k, the ratio of the first preset time period to the preset time interval is set to 1/(k-1).
In the embodiment of the present invention, the ratio of the charging current of the charging pad to the current input to the auxiliary power source is k, that is, the power ratio between the charging pad and the auxiliary power source is k, that is, assuming that the power of the charging pad is k watts per second, the power of the auxiliary power source is 1 watt per second, the charging power of the battery is k-1 watt per second, in this case, the first preset time period may be set to 30 seconds or 1 minute, and the corresponding preset time interval is set to 30 (k-1) seconds or 60 (k-1) seconds. At this time, in a preset time interval, the battery is in a discharging state, the discharging electric quantity is 30 (k-1) × 1 watt, the battery is in a charging state in a first preset time period, the charging electric quantity is 30 × (k-1) watt, and therefore the result can be obtained that under the setting, the charging electric quantity of the battery in each first preset time period is equal to the discharging electric quantity of the battery in the preset time interval, charging and discharging are balanced, and over-discharging of the battery can be avoided.
In some embodiments, the auxiliary power supply control method further comprises: acquiring the current environment temperature; determining a ratio adjustment coefficient according to the current environment temperature; and adjusting the ratio of the first preset time length to the preset time interval according to the ratio adjustment coefficient.
In the above embodiment, in order to ensure that the battery is not over-discharged, a control method of charge-discharge balance is provided. But in some cases not more than guaranteed charge-discharge balance.
For example, when the ambient temperature is low, even if the fan fails, the time required for the UPS to raise the temperature to the shutdown temperature is long, so that the charging time of the charging pad can be properly increased, that is, the time of one switching cycle (that is, the time for switching the charging pad power supply mode to the battery power supply mode and then back to the charging pad power supply mode) is increased, thereby effectively reducing the switching times, avoiding the influence of frequent switching on the auxiliary power supply, and ensuring the stable operation of the auxiliary power supply.
When the ambient temperature is higher, the time required for the UPS to raise the temperature to the shutdown temperature is shorter, and since the stable operation of the auxiliary power supply needs to be preferentially ensured, the discharge time of the battery in each switching period can be slightly prolonged, and although the battery may be overdischarged after a plurality of switching periods, compared with the mode of only using the battery power supply mode in the prior art, the time for reaching the overdischarge can be greatly prolonged, and therefore, the service life of the battery can also be prolonged.
Therefore, in the embodiment of the present invention, when the ambient temperature is low, a positive feedback ratio adjustment coefficient is calculated, so that the ratio of the first preset duration to the preset time interval is increased. And when the ambient temperature is higher, calculating to obtain a negative feedback ratio adjustment coefficient, so that the ratio of the first preset time length to the preset time interval is reduced. For example, let the ambient temperature be T and the first adjusted temperature be T 1 The second adjustment temperature is T 2 ，T 1 <T 2 The ratio adjustment coefficient is lambda, and the ratio of the first preset time length to the preset time interval is set to be 1/(k-1). At T<T 1 When λ ∈ (1, 2) and the adjusted ratio = 1/(k-1) ×, or λ ∈ (0, 1/(k-1)) and the adjusted ratio = 1/(k-1) + λ. At T<T 1 When λ ∈ (0, 1) and the adjusted ratio = 1/(k-1) ×, or λ ∈ (-1/(k-1), 0) and the adjusted ratio = 1/(k-1) + λ.
In some embodiments, the fan unit comprises a plurality of fans; the fan unit faults are partial fan faults or all fan faults. Correspondingly, the power supply control method of the auxiliary power supply further comprises the following steps: when the fan unit failure is partial fan failure, starting the fan which does not fail; and adjusting the ratio of the first preset time to the preset time interval according to the number of the started fans and the total number of the started fans.
In the embodiment of the invention, if the total number of the fans is C, the number of the started fans is C 1 If the ratio of the first preset duration to the preset time interval is set to 1/(k-1), the adjusted ratio is: [ 1/(k-1)]*[C/(C-C 1 )]。
When C is present 1 When =0, i.e. when all fans are out of orderAnd the adjusted ratio is as follows: 1/(k-1) × 1, maintaining the ratios in the above examples.
When C is present 1 >0, namely when partial fans are all in fault, following C 1 Increase of (2), C/(C-C) 1 ) And gradually increasing, the corresponding first preset time length is increased, and the preset time interval is reduced, namely the starting time of the charging panel is prolonged.
When C is 1 C = C, namely when all fans are normal, C-C 1 ＝0，C/(C-C 1 ) → infinity, the adjusted ratio is: 1/(k-1) ∞, i.e. the charging plate is always active and the battery is not active.
In some embodiments, S220 may include: acquiring the working temperature of the uninterruptible power supply; if the working temperature is lower than a first preset temperature, switching the power supply mode of the auxiliary power supply from a battery power supply mode to a charging panel power supply mode; if the working temperature is higher than a second preset temperature, switching the power supply mode of the auxiliary power supply from the charging panel power supply mode to a battery power supply mode; wherein the first preset temperature is lower than the second preset temperature; the second preset temperature is less than the shutdown temperature.
In the embodiment of the present invention, when the operating temperature is lower than the first preset temperature, it is considered that there is no shutdown risk, and therefore the charging panel power supply mode may be switched to.
In conclusion, the beneficial effects of the invention are as follows:
firstly, when a fan of the uninterruptible power supply fails, switching a power supply mode of an auxiliary power supply from a charging panel power supply mode to a battery power supply mode; and then alternately switching the power supply mode of the auxiliary power supply between the charging panel power supply mode and the battery power supply mode according to preset conditions, wherein the preset conditions are used for ensuring that the battery is not over-discharged. Through use charging panel and battery when fan trouble in turn for auxiliary power source power supply, and when the charging panel was auxiliary power source power supply, the charging panel can charge to the battery again to under the prerequisite of guaranteeing the inside temperature of uninterrupted power source is too high, effectively avoid the battery to cross put.
2. The working time ratio of the charging plate and the battery is adjusted through the ambient temperature, the adaptability can be changed according to the actual situation, and the stop of the auxiliary power supply caused by overheating is avoided.
3. Through the operating time of adjusting the charging panel according to the trouble condition adaptability of fan, can reduce the discharge time of battery when partial fan trouble, effectively avoid the battery to cross to put.
