A voltage-stabilized starting power supply for automobiles

Abstract

The invention discloses an automobile voltage-stabilized starting power supply, comprises a housing, a charging line positive electrode, a charging line negative electrode, a charging indicator lamp,a power supply indicator lamp, an overcurrent and overvoltage indicator lamp, a display screen, a startup switch, a USB interface, a charging interface, a transmission line, a solar panel, a control panel, a charging cell, a charging control module, a microprocessor, an overcharge and overdischarge protection module, a discharge control module and a display device. The invention has the advantagesthat: the design of the power supply for the voltage-stabilized starting of the automobile is reasonable, the output port of the charging control module is connected with the battery cell through a transmission line, the input port of the charging control module is connected with the charging interface through a transmission line, and the charging control module is connected with the solar cell panel through a transmission line, when the battery cell is short of power, the battery cell can be inserted into the alternating current through a charging interface, the current fills the battery cell through the charging control module, and when there is no alternating current, the solar cell panel supplies power to the battery cell.

Description

technical field [0001] The invention relates to a power supply device, in particular to a voltage-stabilized starting power supply for automobiles. Background technique [0002] Car starting power supply, also called "car emergency starting power supply". A portable starting power supply integrating power supply and charging functions, which can help the car to start when the car is turned off and breaks down and cannot be started. At the same time, it can also charge digital devices such as mobile phones and tablet computers anytime and anywhere. Generally, lithium batteries are used as the power storage unit. Compared with mobile phone mobile power, the capacity of the car's starting power is large, and it is convenient and quick to use; [0003] With the progress of social development, more and more people own their own cars, which brings great convenience to people. Automobile technology is very mature, but in some respects it is not perfect. The existing starting bat...

Problems solved by technology

The existing starting batteries of automobiles are all lead-acid batteries. In some areas where the temperature is relatively cold, lead-acid batteries cannot be discharged at a high rate under low temperature conditions, resulting in the failure of the car to start, which brings great inconvenience to people.

If the vehicle is started multiple times at this time, it will also cause certain damage to the battery and starter. There are also many situations, such as parking the vehicle for a long time, forgetting to turn off the electronic equipment in the car, etc., which will cause the battery to lose power and fail to start. Vehicles need improvement
