Real time on line uninterrupted direct current power source

Abstract

The invention relates to a real-time online continuous direct current power, which includes: AC / DC transformation model, the secondary battery group, charging unit and CPU monitoring unit. The output voltage of the AC / DC transforming unit is higher than the output voltage of the secondary battery group. Two diodes D1 and D2 are connected in the output circuits of the AC / DC transforming model and the secondary battery group in series, if the D1 is conducted, the load is supplied by the AC / DC transforming model, if the D2 is conducted, and the load is supplied by the secondary battery group. It is totally real-time online, zero switch; the secondary battery group need not the long period float charging state, supplies the better protection to battery; it can detect the battery state in real-time, maintain the battery performance automatically, realizes the intelligent management.

Description

technical field [0001] The invention relates to a real-time on-line uninterrupted direct current power supply. Background technique [0002] In modern life, all kinds of power sources are full of us. With the development of science and technology and the improvement of people's living standards, our demand for uninterrupted DC power supply is increasing, and the requirements are getting higher and higher. The existing technology is to directly connect the output of the secondary battery pack between the AC / DC module and the load device in parallel to obtain real-time online and zero switching time; or to continuously detect whether the system is powered off through the detection circuit to determine Whether to switch the circuit, the output power is provided by the secondary battery pack. [0003] The first method will keep the secondary battery pack in the floating charge state all the time, which is at the cost of sacrificing the life of the secondary battery pack. Over ...

Problems solved by technology

[0003] The first method will keep the secondary battery pack in the floating charge state all the time, which is at the cost of sacrificing the life of the secondary battery pack. Over time, the life of the battery is exhausted while waiting

At the same time, since the secondary battery pack is always in the floating charge state, it is impossible to judge the real charge and performance of the battery, and the intelligent management of the battery cannot be realized.

[0004] In the second way, since the system determines whether the output power is provided by the secondary battery pack by continuously detecting whether the system is powered off, it will not be able to obtain real-time online and zero switching time due to switching circuits.

[0005] In the prior art, no matter what state the battery is in, the same fixed charging mode is used, which greatly damages the life of the battery pack. In addition, it is impossible to correctly judge the charge and performance of the battery. Due to the lack of understanding of the actual situation of the battery, It will cause the battery to close to failure without knowing it, and it will not be able to get enough output when the system is powered off, causing an accident

[0006] In the prior art, because there is no module with communication function, remote monitoring cannot be realized

[0007] Due to the lack of modular design in the prior art, when users have different demands on power, it is impossible to flexibly match modules with different powers to meet various requirements
