适配器和充电控制方法
Abstract:
一种适配器(10)和充电控制方法，该适配器(10)包括：功率转换单元(11)，用于对输入的交流电进行转换，以得到适配器(10)的输出电压和输出电流，适配器(10)的输出电流为第一脉动波形的电流；采样保持单元(12)，与功率转换单元(11)相连，当采样保持单元(12)处于采样状态时，采样保持单元(12)用于对第一脉动波形的电流进行采样，当采样保持单元(12)处于保持状态时，采样保持单元(12)用于保持第一脉动波形的电流的峰值；电流采集控制单元(13)，与采样保持单元(12)相连，用于判断采样保持单元(12)是否处于保持状态(2310)，并在判断出采样保持单元(12)处于保持状态的情况下，采集采样保持单元(12)保持的第一脉动波形的电流的峰值(2320)。上述适配器(10)能够提高电池的使用寿命。
Abstract(English):

Provided are an adapter and a charging control method, the adapter comprising: a power conversion unit, used for converting an inputted alternating current so as to obtain an output voltage and an output current of the adapter, the output current of the adapter being a current having a first pulsed waveform; a sampling and holding unit, connected to the power conversion unit, the sampling and holding unit being used for sampling the current having the first pulsed waveform when the sampling and holding unit is in a sampling state, and holding a peak value of the current having the first pulsedwaveform when the sampling and holding unit is in a holding state; a current collection control unit, connected to the sampling and holding unit, and used for determining whether the sampling and holding unit is in the holding state, and collecting the peak value of the current having the first pulsed waveform held by the sampling and holding unit upon determining that the sampling and holding unit is in the holding state. The adapter increases the service life of batteries.
