基于图7所示的实施例中，当处理器将直充控制开关设置为导通状态，控制充电器按照第一充电模式进行充电时，该充电方法，还可以包括如下步骤，如图9所示：
在步骤901中，处理器通过充电芯片第i次检测电池的电压是否达到第i阈值。
在处理器控制充电器按照第一充电模式对电子设备进行充电时，处理器每隔预设时间通过充电芯片第i次检测电池的电压是否达到第i阈值，i为正整数。
在一个示例性的例子中，在处理器控制充电器按照第一充电模式对电子设备进行充电时，处理器首先通过充电芯片检测电子设备电池的电压是否达到4.2伏特(V)。
在步骤902中，在电池的电压达到第i阈值时，处理器根据电池的电压生成充电控制指令。
若处理器通过充电芯片检测到电池的电压达到第i阈值，则处理器根据检测到的电池的电压生成充电控制指令，该充电控制指令用于控制充电器控制充电电流。

可选的，处理器通过第一传输芯片向充电器发送i次充电控制指令后，通过充电芯片检测充电器的充电电流是否小于电流阈值。
比如：充电器通过充电芯片检测充电器的充电电流是否小于1安培(A)。
在步骤907中，在充电电流小于电流阈值时，处理器将直充控制开关设置为断开状态，通过充电芯片按照第二充电模式进行充电。
当处理器检测到充电器的充电电流小于电流阈值时，处理器将直充控制开关设置为断开状态，通过充电芯片按照第二充电模式进行充电。也即，处理器在检测到充电器的充电电流小于电流阈值时，处理器将充电器冲第一充电模式切换至第二充电模式进行充电。
在一个示例性的例子中，如图10所示为处理器通过第二传输芯片控制充电器的充电电流的简单流程图；在步骤01中，处理器通过充电芯片检测电池的电压是否小于4.2V；在步骤02中，若电池电压大于4.2V，则处理器根据电池的电压生成充电控制指令，并通过第一传输芯片发送给充电器，充电器根据充电控制指令控制整流控制芯片降低充电电流，将充电器的充电电压调整为4.4V，充电电流调整为5A；在步骤03中，第一个预设时间后，处理器通过充电芯片检测电池的电压是否达到4.4V；在步骤04中，若电池的电压达到4.4V，则处理器根据电池的电压生成充电控制指令，并通过第一传输芯片发送给充电 器，充电器根据充电控制指令控制整流控制芯片降低充电电流，将充电器的充电电压调整为4.4V，充电电流调整为3A；在步骤05中，第二个预设时间后，处理器通过充电芯片检测电池的电压是否达到4.4V；在步骤06中，若电池的电压达到4.4V，则处理器根据电池的电压生成充电控制指令，并通过第一传输芯片发送给充电器，充电器根据充电控制指令控制整流控制芯片降低充电电流，将充电器的充电电压调整为4.4V，充电电流调整为1.5A；在步骤07中，随着电池电压的的逐渐增大，充电电流会逐渐变小，第三个预设时间后，处理器通过充电芯片检测充电器的充电电流是否小于1A；在步骤08中，若充电电流小于1A，则处理器控制直充控制开关处于断开状态，通过充电芯片按照第二充电模式进行充电。其中，由于电池的电压与充电器的充电电压相等时，充电电压无法对电池进行充电，而由于电池及电路板上阻抗的存在使得充电芯片检测到的电池的电压虚高，因此，通过降低充电电流的方式降低电池的电压，从而实现更快的为电池进行充电的效果。
综上所述，本公开实施例中提供的充电方法，处理器通过通信控制芯片获取与硬件充电接口相连的充电器的类型；在充电器的类型是预定充电器时，处理器将直充控制开关设置为导通状态，控制充电器按照第一充电模式进行充电；解决了相关技术中电子设备不能同时兼容两种快速充电方法的问题；达到了根据充电器的类型的不同，使用不同的充电模式对电子设备进行充电，实现了电子设备可以兼容不同的充电模式的效果。
另外，处理器通过第一传输芯片按照预定传输协议向充电器发送充电控制指令，有利于保证充电控制指令在数据传输中的稳定性，提高了充电过程中的安全性。
