Problems solved by technology

[0005] However, CC / CV charging requires many detection points and requires high-precision detectors, resulting in a significant increase in cost
However, when the pulse charging mode enters the pulse charging mode in the later stage, the requirements for the protection IC of the battery cell are very high, and the circuit structure is relatively complicated, which is quite inconvenient.

Embodiment Construction

[0029] For making the purpose of the present invention, method feature and effect thereof, do further understanding and understanding, give embodiment to coordinate drawing, describe in detail as follows:

[0030] figure 1 It is a schematic diagram of a preferred specific embodiment of the method according to the present invention. As shown in the figure, firstly connect a plurality of batteries in series to form a battery pack 1, and connect the battery pack 1 with a power supply 2 (for example: step-by-step variable charger or a linear variable charger, but not limited to) in series, wherein each battery can be a high capacity capacitor or a lithium battery. In addition, a first voltage dividing resistor R1 and a second voltage dividing resistor R2 are connected in series to form a series voltage dividing resistor, and the series voltage dividing resistor is connected in parallel with the battery pack 1 . Then a microcontroller 4 comprising an analog / digital converter (not ...

Abstract

The invention provides a battery charging method, which cooperates with a microcontroller and a series voltage dividing resistor to control the size of the charging power supply, so that each battery can achieve the best charging effect. In the present invention, the microcontroller is used to detect the total terminal voltage of the battery pack through series voltage dividing resistors, and after the first round of charging is completed for each battery in the battery pack, the microcontroller is used to order the power supply to reduce the output charging current, and then The batteries in the battery pack are charged for a second round, and this cycle is repeated for a predetermined number of times. In this way, each battery in the series-connected batteries being charged can be charged to an optimal state.

Description

technical field [0001] The present invention relates to a battery charging method, especially a method in which when a power supply unit charges a plurality of batteries connected in series, it cooperates with a microcontroller and series voltage dividing resistors to achieve the best charging effect for each battery. method. Background technique [0002] With the increasing demand for portable electronic products such as digital cameras, PDA, MP3, ..., etc., the requirements for rechargeable battery capacity are also greater, and the requirements for charging time are also shorter. In addition, the volume of the charger is also increasing. Thinner is required. Therefore, a charger with small size, fast charging, low price and long life seems to be the trend of future development. [0003] At present, most of the existing battery chargers use CC / CV charging. Among them, CC refers to charging the battery with a constant current; CV refers to charging the battery with a con...
