Abstract

The invention belongs to the technical field of capacitors, and discloses a method for calculating the discharge time of a capacitor, and a mobile terminal. The method comprises the following steps that: a capacitor chip acquires a voltage U1 before the capacitor discharges; the capacitor chip acquires a voltage U2 after the capacitor discharges; the capacitor chip calculates discharge capacity according to the voltage U1 before the capacitor discharges and the voltage U2 after the capacitor discharges, wherein the discharge capacity is calculated according to formulas: Q=C*(U1-U2) and discharge capacity=Q*1 / 3.6milliampere*hour; and the capacitor chip calculates the discharge time of the capacitor according to a clock electrically connected with the capacitor chip, wherein the discharge time of the capacitor is calculated according to a formula: T=discharge capacity / consumed current. By the method, when the voltages on the two sides of the capacitor change, the capacity of the capacitor can be accurately calculated and the time is calculated according to the capacity of the capacitor, so that the application of the capacitor is expanded.

Description

technical field [0001] The invention belongs to the technical field of mobile terminals, in particular to a method for calculating the discharge time of a capacitor and a mobile terminal Background technique [0002] With the continuous development of mobile terminal technology, users have higher and higher requirements for mobile terminal functions. [0003] Capacitors are widely used in mobile terminals or data cards. The so-called capacitors are electronic components that accommodate and release charges. The basic working principle of a capacitor is charging and discharging, and of course rectification, oscillation and other functions. In addition, the structure of the capacitor is very simple, mainly composed of two positive and negative electrodes and an insulating medium sandwiched between them, so the type of capacitor is mainly determined by the electrodes and the insulating medium. Several types of capacitors, such as electrolytic capacitors, paper capacitors, and...
