移动通信终端及其双电池充供电的切换方法技术

一种移动通信终端及其双电池充供电的切换方法，该终端主板上设有两电池接口以及与其相连接的充供电电路，该终端开机之后，该切换方法包括以下步骤：Ｓ↓［１］、由Ａ电池供电，Ｂ电池闲置，并记录两电池的电压；Ｓ↓［２］、当Ａ电池电压不满足供电条件时，判断是否有充电器插入；Ｓ↓［３］、如果有充电器插入，则Ａ电池同时供电和充电，Ｂ电池继续闲置；Ｓ↓［４］、当Ａ电池充满电而Ｂ电池未充满电时，由Ａ电池供电，Ｂ电池充电；Ｓ↓［５］、如果两电池都充满电，则返回步骤Ｓ↓［１］。本发明专利技术采用双电池进行充供电，满足了手机电池大容量的需求。并且，当遇到突发事件的时候，如拔除电池，软件会收到由系统发出的中断，此时会立刻切换由另一块电池供电，以保证手机不断电。

Mobile communication terminal and double battery charging and switching method thereof

A switching method of mobile communication terminal and double battery charge power supply, battery charging and power supply circuit is provided with two interfaces of the terminal board and connected with the terminal, after the boot, the switching method comprises the following steps: S: 1, powered by A battery, B battery voltage idle, and record the two battery S; 2 case, when the battery voltage of A power supply does not meet the conditions, determine whether the charger is plugged; S: 3, if there is a A battery charger plugged in, at the same time, power supply and charging, the battery B S down to idle; 4, when the battery is fully charged and B A battery is not charged when powered by A battery, B battery; S: 5, if the two battery is full of electricity, then return to step 1: S. The invention adopts double batteries to charge and supply power, and meets the requirement of large capacity of mobile phone batteries. Also, when an emergency happens, such as pulling out the battery, the software will receive an interruption from the system, which will immediately switch to another battery to ensure that the phone is not power off.
