Description
Technical Field
The invention relates to a charging controller, in particular to a solar charging controller of a small electric vehicle.
Background
The small-sized electric vehicle is labor-saving and convenient, and enters thousands of households at present, but the charging and the endurance of the electric vehicle are always difficult. At present, a safer charging mode is centralized charging and managed by a specially-assigned person. The charging needs to consume extra manpower, and for a large number of vehicle owners, the centralized charging place is generally far away from home, and the centralized charging place is dozens of meters less and hundreds of kilometers more, so the vehicle owners are generally unwilling to charge the centralized charging place.
In addition, a less safe charging method is used for charging at home or in a public corridor, and for electric tricycles, the charging is basically carried out in the public corridor, so that the charging method has serious potential safety hazards, and occupies public space, so that the neighborhood is in tension.
Both of the above charging methods can be performed only at a fixed place and at a concentrated time. Solar charging is a better charging mode which can be used for charging in any time occasion.
At present, the solar charging is mainly controlled by fast and slow charging control, signal identification control, self-checking control and the like, and the control mode is necessary for an electric car, but the control mode is not used for a small electric vehicle due to high cost and complex structure.
Therefore, a controller suitable for a small-sized electric vehicle, which has a simple structure, is required.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 shows a schematic block diagram of the circuit of the present invention, and fig. 2 shows a schematic block diagram of the circuit of the present invention, and the operation thereof is described below.
The current sent by the solar power generation panel is divided into two branches after passing through the diode, one branch reaches the base electrode of the triode through the green light emitting diode after passing through the resistor R, the other branch reaches the collector electrode of the triode, when the triode meets the conduction condition, the collector electrode is conducted with the emitter electrode, the current returns to the cathode of the solar power generation panel after passing through the battery, and the circuit is a charging circuit of the battery.
In the charging circuit, the conducting condition of the triode is that the voltage of the base electrode is higher than the voltage of the emitter electrode by about 0.7V, and the charging circuit can be realized by selecting a proper resistor R according to the rated voltage of the battery.
When the charging circuit is operating, the green light emitting diode operates to indicate that the battery is charging.
In the circuit, a branch circuit passes through the voltage stabilizing diode and the red light emitting diode after passing through the resistor R and then reaches the negative electrode, but the voltage stabilizing diode is in a cut-off state due to the current limitation of the resistor R, and the current cannot pass through, so that the red light emitting diode cannot be lightened.
When the voltage of the battery rises to a level which does not meet the conduction condition of the triode, the collector and the emitter are disconnected, the base and the emitter are also disconnected, at the moment, the battery is not charged any more, and the green light-emitting diode does not work any more.
At the moment, the voltage of the solar power generation panel is completely applied among the resistor R, the voltage stabilizing diode and the red light emitting diode, the voltage stabilizing diode is in a conducting state, so that a circuit is formed, and the red light emitting diode is lightened to indicate that the battery is fully charged.
