Problems solved by technology
However, the quality of the chargers on the market today is uneven, and the rated power is also different, so that users have to consider the adaptation between the charger and the portable device, otherwise it may introduce problems such as the charger cannot be used, the charging time is too long, The battery is not fully charged and other problems, what's more, there may be safety hazards if excessive charging current is drawn from a charger with poor performance
Existing technology does not allow portable devices to automatically adapt to the charger

Embodiment Construction
[0030] The gist of the present invention is to overcome the deficiencies of the prior art, and provide a method for automatically adapting a charger for a portable device, which can better enable the charger and the portable device to perform adaptive charging, and can better handle charging time, charging To a certain extent, it solves the situation of dissatisfaction with charging due to adaptation, and is easy to operate, safe and reliable. The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.
[0031] Method flow chart of the present invention is as figure 1 As shown, a method for automatically adapting a charger for a portable device involves the following definition data,
[0032] nIchgDef is the preset charging current; bIchgFinishSet is used to record whether the adaptation charging has been completed. When it is 0, ...

The invention discloses a method for automatically adapting a charger to portable equipment. When the charger is connected with the portable equipment, the equipment is charged by preset charging current nIchg=nIchgDef, and a voltage value nVchg of the charger is periodically detected. In the detection of each time, nVchg is judged whether to be greater than a preset charger voltage threshold value nVchgThre or not, and the charging current for the portable equipment is stepwise increased by nIchg=nIchg+nIchgStep or decreased by nIchg=nIchg-nIchgStep according to a judgment result to realize the automatic adaptation of the charger to the portable equipment. By the method, the charger and the portable equipment can be relatively better adapted for charging, charging time and a charging degree can be relatively better processed, and the condition of charging incompletion caused by the adaptation can be well solved; and the method is convenient to operate, safe and reliable.
Description
technical field [0001] The invention relates to a charging method for a portable device, in particular to a method for automatically adapting a charger for a portable device. Background technique [0002] In today's mobile life, portable devices such as Personal Digital Assistant (PDA), Feature Phone (Feature Phone), Smart Phone (Smart Phone), Tablet Personal Computer (Tablet Personal Computer), etc., have changed the way of human life Habit. In today's society, almost everyone has one or more portable devices. The popularity of portable devices is due to their convenience, but relatively, because they use portable power sources, unlike ordinary desktop computers, which have a stable power supply environment, how to use them in various It is also an important problem that portable devices can be operated stably in any place. [0003] During the movement, the portable device is powered by its equipped battery. When the battery power is exhausted, a charger is required to p...
