Embodiment Construction

[0011] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0012] There is a defect in the battery charging circuit, which cannot automatically switch or turn off the power supply when the battery capacity is full. As a solar lighting system, under normal circumstances, the battery capacity supplement is realized by the electric energy generated by the solar panel. Only when the battery cannot be supplemented by the solar battery energy in continuous rainy days, the AC supplementary charging will work. Once the battery capacity reaches the requirement The charger should exit the charging connection state, and can provide charging for the storage battery in time when the energy of the solar battery recovers. The present invention adds automatic conversion circuit in the circuit of Fig. 1.

[0013] Depend on figure 2 It can be seen that the present invention includes: a pulse width modulation control ch...

Abstract

The invention is related to an automatic switching circuit for charging the storage battery by commercial power in the photovoltaic lighting system, the circuit being converted into the automatic switch state based on the present technology. The invention has a beneficial effect that when the solar cell is undercharged to result a capacity loss of the storage battery, the circuit can be timely switched to the state where commercial power charges the storage battery, and the supplementary charging circuit is automatically shut off as a result of a normal charging of the solar cell.

Description

technical field [0001] The invention relates to a storage battery in a solar lighting system, in particular to an automatic switching circuit for supplementary charging of the storage battery with commercial power. Background technique [0002] In a solar lighting system, the solar cell converts sunlight into electrical energy and stores it in the battery, and then supplies the electrical energy in the battery for lighting at night, and completes this conversion over and over again. However, in practical applications, when there is insufficient sunshine in continuous rainy days, the solar battery cannot provide enough electric energy to charge the battery, and the battery is insufficiently charged. Damage, which is a practical problem in solar lighting applications. [0003] It can be seen from Figure 1: it is the basic circuit structure of DC stabilized voltage power supply. The circuit is a 150W charger with an input of 220VAC, an output of 13.6VDC, and a maximum chargin...
