Embodiment
With reference to figure 1, a kind of method of critical battery failure detection of the present invention, comprise the following steps：
A, UPS battery is switched into battery mode, initial value is assigned to count value, and judge cell voltage whether in full
Charge state, if so, then performing step B；Otherwise, battery detecting is exited；
B, discharge current is sampled, and judges discharge current whether in the range of defined inversion discharge current, if

With reference to figure 2, as a kind of further improvements in methods of described critical battery failure detection, the step C bags
Include：
C1, current current ratio is read, according to current ratio, inquiry obtains battery and be discharged to voltage from full charge state facing
The discharge time of boundary's judgment value；
C2, according to discharge time, the crash time is calculated；
C3, according to the crash time, by the initial value of count value divided by crash time, obtain corresponding to time counting value；
C4, the time counting value corresponding to, real-time count value is reduced to the time counting value of a unit.
UPS structure is as shown in figure 3, UPS mainly operates in four states, holding state, city's electricity condition, battery inversion shape
State and off-mode.In holding state or city's electricity condition, civil power can be charged by charger to battery, and be in inversion shape
State, then UPS by inverter to battery discharge.
As shown in figure 4, the state-of-charge of battery and voltage relationship are a linear relationships, for standard 12V electricity
Pond, if not with voltage when carrying more than 13V, it is believed that the battery is in full charge state.
As a kind of further improvements in methods of described critical battery failure detection, in addition to：By critical battery mark
Will position is preserved into flash memory.
As a kind of further improvements in methods of described critical battery failure detection, in addition to：Read from flash memory
Critical battery flag bit, judge whether it is 1, if so, then controlling UPS battery LED to carry out flickering display；Otherwise, UPS battery
LED maintains normal display.
As a kind of further improvements in methods of described critical battery failure detection, the initial value in the step A
For OxFFFF.
As a kind of further improvements in methods of described critical battery failure detection, the default voltage critical is sentenced
Disconnected value is 11V.The rated capacity C of UPS battery, unit ampere-hour Ah, it is discharge current peace A and hour discharge time h product.
The current strength of battery at work is often represented with multiplying power, is write and is NCh.If rated capacity is 7AH batteries, if strong with 2C electric currents
Degree electric discharge, then discharge current is equal to 2 × 7=14A.The final voltage of UPS battery refers to that cell voltage drops to not during electric discharge
As for the minimum angle value for causing damage.Under the electric current of different multiplying, the curved line relation of voltage and time are as shown in Figure 5.Can
To find out, in battery allowed band, discharge current is bigger, and final voltage is lower, but battery capacity but diminishes on the contrary.In order to
Comprehensively obtain the capacity of battery, it is desirable to which the cell discharge voltage value of setting is more low better, it is contemplated that UPS's is uninterrupted defeated
Go out and avoid the damage to battery, and the height that the magnitude of voltage of hope setting is tried one's best.In conjunction with the electric current model of the UPS occasions used
Size is enclosed, therefore sets voltage critical judgment value as 11V.
As a kind of further improvements in methods of described critical battery failure detection, during setting in the step F
Between be 1s.
With reference to figure 5, according to battery discharge current and the relation of capacity, can by the way that its data will be stored in advance,
So that energy real-time query reading UPS battery discharges into the time value of voltage critical judgment value under different current ratios.Setting is faced
Boundary's time is the 60% of query time.For the more preferable digital quantization time, it is specified that count initial value for 0xFFFF, it is specified that the time
Count value corresponds to the numerical value to be subtracted in crash time 1s for each electric current.Assuming that current ratio is 1C, battery is put from full electric charge
Electricity to 11V standard time is 25 minutes, can inquire about and draw from data storage.It is 25 × 60%=to draw the crash time again
15Min, that is, 900s.The initial value T=0xFFFF of count value just needs the 900s times to reduce to 0.In the case of defined,
Counter every one second subtrahend once, then the subtracted time per second is exactly T/900=65535/900=73.By that analogy, from
0.3C to 4C, made every 0.1C and subtract corresponding time counting value.
Above is the preferable implementation to the present invention is illustrated, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent variations on the premise of without prejudice to spirit of the invention or replace
Change, these equivalent deformations or replacement are all contained in the application claim limited range.
