Abstract

The invention discloses a battery fast charging power supply based on a charging detection circuit, which is characterized in that it mainly consists of a transformer T, a diode rectifier U1, a one-way thyristor VS1, a triode VT1, a triode VT5, a polar capacitor C1, a resistor R1, and a diode D1 , a voltage adjustable control circuit, a differential amplifier circuit, a ripple suppression circuit connected in series between the negative output terminal of the diode rectifier U1 and the base of the triode VT5, and a charging detection circuit connected to the processing chip U2 and the triode VT5 respectively . The invention can eliminate the instantaneous large current of the rechargeable battery, effectively eliminate the polarization phenomenon of the rechargeable battery, and the invention can output a large current to charge the rechargeable battery repeatedly, and the output charging current is higher than that output by the existing charging power supply The charging current is more than 10 times, thereby improving the charging efficiency of the present invention.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a battery fast charging power supply based on a charging detection circuit. Background technique [0002] Under the background of global energy shortage and increasing environmental protection requirements, countries all over the world are vigorously developing energy-saving and environment-friendly rechargeable batteries. Rechargeable batteries are widely used as a portable power source in different electronic products such as mobile phones, cameras, and laptops. However, the charging power source of the existing rechargeable battery has the problem of low charging efficiency, which causes the charging time of the rechargeable battery to be too long and cannot meet people's requirements. [0003] Therefore, it is a top priority to provide a fast charging power supply for a rechargeable battery that can improve charging efficiency. Contents of the invention [0004] The object of t...
