Abstract

The invention provides a fast charging device and its method. A current limiting unit is employed to receive a voltage power source provided by a current limiting voltage power source and draw the maximum output current of the current limiting voltage power source, which is converted by a step-down converter unit into a low-voltage constant-current power for being supplied to a countercurrent prevention unit so as to produce and supply a display signal representative of low-voltage constant-current power source to a charging display unit. The countercurrent prevention unit charges a super capacitor and prevents the super capacitor from reversely discharging the fast charging device. A current limiting control unit senses the voltage on the super capacitor to generate a current limiting control signal for regulating the output of the current limiting unit, so as to increase the charging current applied to the super capacitor and decrease the charging time, thereby achieving a fast charging function. Furthermore, the charging display unit is used to display the charging status of the super capacitor.

Then, the charging current can exceed 500 mA, and the magnitude of the charging current varies with the conversion efficiency of the step-down conversion unit 2A. m. The disadvantage of the above-mentioned conventional technology is that after the current limiting unit is limited, the charging current of the descending conversion is usually a fixed value, that is, the constant current charging, so although the charging current can be greater than that provided by the (four) voltage source. 〇mA 轮 current, but when starting charging, 'super capacitor's power is small, so the coffee, the power supply only needs to provide a small output current to the current limiting unit, as the voltage of the super capacitor rises due to charging, The output motor of the US_5V voltage power supply will be Ai Da. Therefore, during the overall charging process, the output current provided by the 5 乂 voltage power supply is not - directly maintained at the maximum value, 5_A, so the charging method of the driving technology has not been achieved.最佳The optimal utilization of the voltage source and the overall charging time is lengthened. 201108555 [Summary of the Invention] The main purpose of the present invention is to provide a fast charging device and a method thereof, which use a current limiting device to receive a voltage power supply provided by a current limiting power supply and to limit the maximum output current of the power supply. Then, the step-down conversion unit converts into a low-voltage constant current power supply to prevent the reverse flow unit and generates a display signal representing the low-voltage constant current power supply to the charging display unit to prevent the reverse current single-header from charging the super capacitor and preventing the super capacitor from being charged to the quick charging device. Reverse discharge 'At the same time, the current limiting control unit senses the voltage of the super capacitor, generates a current limiting control signal' to adjust the output of the current limiting unit, and displays the charging state of the super capacitor by using the charging display unit. The invention is based on the fact that the entire charging process does not take the maximum output current of the current limiting voltage source for generating the maximum charging current for charging the super capacitor. Therefore, it can overcome the conventional charging in the prior art. The problem of current is to shorten the overall charging time to achieve fast charging' and improve charging efficiency.

The current limiting unit 1 receives the current limiting voltage power supply VIN to generate a current limiting power supply signal. The step-down conversion unit 2 generates a low voltage power supply and a display signal corresponding to the low voltage power supply according to the current limiting power supply signal to step down the current limiting voltage power supply. 'Preventing the counter current unit 30 from supplying the low voltage power to the super capacitor 90 and charging' while preventing the super capacitor 90 from generating a counter current discharge, that is, preventing the w super capacitor 90 from flowing the stored power back to the fast charging of the present invention in a reverse current manner. Device. The current limiting control unit 4 detects the voltage of the super capacitor 9 , to generate a current limiting control signal, and the current limiting unit 10 receives the current limiting control signal to adjust the current limiting power supply. Therefore, the current limiting unit 1〇, the buck converting unit 2〇, the anti-backflow unit 30, the super capacitor 90, and the current limiting control unit 40 form a feedback control loop that can dynamically adjust the anti-backflow according to the voltage of the super capacitor 90. The charging current of the super capacitor 90 of the unit 30 is simultaneously determined by the unit continuous current limiting voltage power supply VIN not taking the maximum rated current, for example, the maximum output current that the USB 5V voltage power supply can provide, ΟπιΑ to achieve the usb voltage power supply Optimal utilization and reduced overall charging time. , the second charging device 50 receives the charging information of the buck converting unit 2 借 not representing the charging state, the charging state can be two 仃 _ / charging has been completed, the current charging voltage value, current charging The percentage of completion, the required charging time, or the total charging time, and the charging information 201108555 can be at least one of numbers, text, and patterns. For example, use at least the - indicator to indicate the charging message, when the indicator is on, it indicates that charging is in progress, and when the indicator is off, charging is complete.

"The main feature of the present invention is that the entire charging period is constant throughout the charging period. (4) The current supply voltage does not take the maximum current. And at the beginning of charging, the maximum charging current ' _ large charging current 彳 depends on the buck conversion unit, and as the voltage of the super capacitor rises due to charging, the charging current of the reverse current unit is also prevented from decreasing. However, the minimum charging current of the countercurrent preventing unit is not lower than the maximum output current that the buck converting unit can provide. • The features of the first embodiment of the present invention will be described in detail below by way of exemplary embodiments.
