Description

Technical Field

[0001] The invention relates to the technical field of UPS uninterruptible power supply, in particular to a backup UPS uninterruptible power supply with battery capacity display. Background Art

[0002] UPS, or uninterruptible power supply, is an uninterruptible power supply with energy storage device. It is mainly used to provide uninterruptible power supply to some equipment with high requirements on power supply stability. When the mains input is normal, UPS stabilizes the mains voltage and supplies it to the load. At this time, UPS is an AC voltage stabilizer.

[0003] UPS power supply is a technology that can continue to provide power to the load when the power supply of the power grid fluctuates or is interrupted. The working principle of the backup UPS power supply is different from that of the direct UPS power supply. When the power of the power grid is normally supplied, the UPS directly transfers the power to the load device through the input end, and charges the battery to store energy at the same time. When the power of the power grid is interrupted or the voltage fluctuates, the UPS will immediately switch to the energy storage battery for power supply. The inverter will convert the DC power of the energy storage battery into AC power and supply it to the load device through the output end.

[0004] Due to the natural aging of the battery over time or the influence of high temperature environment, the health of the battery may decline. Its important indicator is the reduction of capacity. When the external power grid is powered normally, the battery is always in a charging state. Since there is no direct parameter display, it is not easy to detect the change of battery health. When the external power supply is interrupted, the battery capacity may decrease and it may not be able to carry the load.

[0054] The working principle of the backup UPS uninterruptible power supply with battery capacity display provided by the present invention is as follows:

[0055] First, multiple batteries 19 are installed at the bottom of the inner wall of the housing 2, and the batteries 19 are connected to the monitoring device 15.

When the grid power is normally supplied, the UPS will directly transfer the electric energy to the load device through the output head 12, and charge the battery 19 to store energy.

In this process, the battery terminal voltage is about 9V, which is sent to the transistors V1 and V2 after being divided by VD1, VD2, and VD3. When the voltage is 9V, both LED lights are on, indicating that the power is sufficient. When the voltage drops, VD5 goes out because the voltage drop cannot be achieved, indicating that the power is low. When the voltage drops again, VD4 will also go out, indicating that the power is exhausted and needs to be charged. For details, please refer to Figure 5 .
