As a preferred scheme, in the embodiment, the solar panel is a flexible solar panel, so that mobile energy storage devices in different shapes can be designed and manufactured conveniently; the load detection circuit adopts a Hall sensor so as to have higher detection precision and excellent external magnetic field interference resistance; the charging control circuit adopts an STM32 microprocessor, so that the complexity of peripheral operation is reduced; the input control switch and the output control switch are electromagnetic relays or electronic switches.
The working process of the device is as follows: (1) when the sun shines, the solar panel outputs voltage, the solar panel outputs a voltage signal to the charging control circuit, and the charging control circuit controls the solar charging indicator lamp to be on; the solar panel also outputs a voltage signal to the charging management circuit, the charging management circuit outputs voltage at the moment, and the load detection circuit detects whether output current exists or not, so that whether the electric equipment is connected to an electric equipment charging interface to be charged or not can be detected, wherein the electric equipment comprises a mobile phone, a tablet personal computer and the like. If the access of the electric equipment is detected, the solar panel directly charges the electric equipment, and the charging control circuit controls the charging indicator lamp of the mobile phone battery to be on; if the access of the useful equipment is not detected, the charging control circuit controls the output control switch to be closed, the charging management circuit directly charges the energy storage battery, and the charging control circuit controls the charging indicator lamp of the energy storage battery to be on. (2) When no sunlight is irradiated, the solar panel does not have voltage output, the solar panel does not output a voltage signal to the charging control circuit at the moment, if the charging control circuit detects that useful electric equipment is connected through the load detection circuit, the charging control circuit controls the input control switch to be closed, so that the output end of the energy storage battery is directly connected with the input end of the charging management circuit, the energy storage battery directly charges the mobile phone, and the charging control circuit controls the charging indicator lamp of the mobile phone battery to be turned on.
In this embodiment, the charging management circuit adopts a CN3722 chip, and the input voltage thereof is provided by a solar panel, more specifically, as shown in fig. 2, the embodiment of the present invention provides the charging management circuit schematic diagram, and the CN3722 chip and the external circuit thereof constitute the charging management circuit. The charging management circuit carries out three charging modes on the energy storage battery, namely: trickle charge, constant current charge, constant voltage charge. Under the constant voltage charging mode, the output voltage of the charging management circuit is divided by a sampling resistor in the external circuit of the chip to set the constant voltage charging voltage; under the constant current charging mode, the output current of the charging management circuit is also used for setting the constant current charging current through a sampling resistor in the chip external circuit. (1) Trickle charging: when the energy storage battery is over-discharged and the voltage at the two ends of the energy storage battery is lower than 66.7% of the preset constant-voltage charging voltage, after the CN3722 chip is judged, the charging management circuit is controlled to charge the energy storage battery in a trickle charging mode, and the charging current at the moment only has the preset constant current15% of the charging current to protect the energy storage battery and avoid damage. (2) Constant current charging: when the voltage at the two ends of the energy storage battery is lower than 95.8% of the preset constant voltage charging voltage and higher than 66.7% of the preset constant voltage charging voltage, the CN3722 chip controls the charging management circuit to enter a constant current charging mode after judgment so as to be beneficial to rapidly charging the energy storage battery; in this charging mode, the charging current is detected by a detection resistor R connected between the CSP pin and the BAT pinCSAnd a reference voltage inside the chip, the reference voltage being VCSP-VBAT200mV, therefore, the constant current charging current is ICH＝200mV/RCS. (3) Constant voltage charging: when the voltage at two ends of the energy storage battery continuously rises and approaches the preset constant voltage charging voltage, the CN3722 chip controls the charging management circuit to enter a constant voltage charging mode after judgment; in this charging mode, the charging voltage output by the charging management circuit is unchanged, but the charging current gradually decreases with the increase of the charging time, when the current flowing through the sampling resistor is lower than 9.5% of the preset constant current charging current, the CN3722 chip considers that the charging process of the energy storage battery is completed, and the charging current thereafter approaches zero. More specifically, as shown in fig. 3, it is a schematic diagram of a charging process of the charging management circuit according to an embodiment of the present invention.
When the charging management circuit is not connected with the input voltage provided by the solar panel or the input voltage is lower than the preset constant voltage charging voltage, the CN3722 chip enters a sleep mode to reduce the power consumption of the circuit.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
