Specific embodiment
Power supply system embodiment
The present embodiment provides a kind of power supply systems, and the corresponding electrical equipment of the power supply system is by taking communication equipment as an example.The confession
Electric system includes photovoltaic generation unit and battery, and in the present embodiment, the photovoltaic module in photovoltaic generation unit corresponding diagram 1 stores
Lithium battery group in battery corresponding diagram 1.As shown in Figure 1, the electric energy output end of photovoltaic module is connected with lithium battery group, moreover,
It is also provided with control cabinet on the electric energy transmission line of photovoltaic module, the phase of electric energy is realized by the power module in control cabinet
Pass processing.
The power supply system further includes photovoltaic generation unit booting-self controller device, which includes intensity of illumination detection
Module, control module and electric energy transmit control switch, and intensity of illumination detection module is realized for detecting intensity of illumination, control module
Booting-self controller, electric energy transmission control switch are arranged on the electric energy transmission line of lithium battery group.Control module sampling connection light
According to intensity detection module, control connection electric energy transmits control switch.
In the present embodiment, control module is by taking the corresponding BMS of lithium battery group as an example, it is, of course, also possible to be that special realize is opened certainly
Dynamic control equipment；Intensity of illumination detection module is by taking photosensitive module as an example, according between intensity of illumination and the intensity threshold of setting
Size relation export varying level signal, such as: when intensity of illumination be less than intensity threshold when, export low level, when illumination is strong
When degree is more than or equal to intensity threshold, high level is exported, the signal of signal receiving end (end T) the connection photosensitive module of BMS is defeated
Outlet can receive level signal corresponding with intensity of illumination.As shown in Figure 1, photosensitive module includes sensing device, such as light
Quick resistance/photodiode.The contact in electric energy transmission control switch corresponding diagram 1 on the electric energy transmission line of lithium battery group
