Problems solved by technology

[0002] With the improvement of living standards, electrical equipment such as electric bicycles and electric vehicles powered by lead-acid batteries has become popular, but different electrical equipment, because the number of lead-acid batteries used is different, the output voltage of the charger used is also different. Chargers for different electrical equipment generally cannot be mixed, so each electrical equipment is equipped with a dedicated charger, which leads to an increase in the cost of electrical equipment

Embodiment Construction

[0027] like figure 1 As shown, a charger that automatically adapts to the voltage of a lead-acid battery pack includes a thyristor intelligent rectifier circuit 1, a switching power supply circuit 2, a voltage sampling circuit, a battery voltage detection circuit 3 and a single-chip microcomputer control circuit 4.

[0028] The thyristor intelligent rectifier circuit 1 is a rectifier circuit capable of changing the output voltage under the action of a control signal.

[0029] The switching power supply circuit 2 is a regulated power supply circuit that can change the output voltage by changing the data of the voltage sampling circuit;

[0030] The battery voltage detection circuit 3 measures the no-load voltage of the battery, and converts the voltage signal into an 8-bit binary digital signal to the single-chip microcomputer circuit 4 through an A / D conversion circuit as a basis for judging the number of battery cells.

[0031] The voltage sampling circuit is a unit of the s...

Abstract

The invention discloses a charger automatically adaptive to the lead-acid battery pack voltage. The charger comprises an intelligent thyristor rectifier circuit, a switch power circuit, a voltage sampling circuit, a battery voltage detection circuit and a single chip computer control circuit, wherein a single chip computer outputs a control signal to the thyristor rectifier circuit according to the number of battery packs to control the conduction angle of the thyristor rectifier circuit; the more the number of the battery packs, the larger the controlled conduction angle of the thyristor and the higher the direct current voltage output by the rectifier; the single chip computer outputs a second signal to the voltage sampling circuit of a switching power supply for changing data of the voltage sampling circuit. Through coordination control in the two aspects, the ratio of a high value to a low value of the output voltage of the switching power supply is as high as 9.

Description

Technical field: [0001] The invention relates to a lead-acid battery charger. Specifically, it relates to a lead-acid battery charger which determines the charging voltage by detecting the voltage of the battery pack, judging the number of lead-acid battery packs, and belongs to the field of electronic technology. Background technique [0002] With the improvement of living standards, electrical equipment such as electric bicycles and electric vehicles powered by lead-acid batteries has become popular, but different electrical equipment, because the number of lead-acid batteries used is different, the output voltage of the charger used is also different. Chargers of different electrical equipment generally cannot be mixed, so each electrical equipment is equipped with a dedicated charger, which leads to an increase in the cost of the electrical equipment. Contents of the invention [0003] The present invention aims at the above deficiencies and provides a lead-acid batte...
