请参见图1,图1是本发明实施例提供的一种多芯片充电装置的结构示意图。如图1所示,多芯片充电装置10,用于为电池11充电,该多芯片充电装置10包括:电源输入接口101、控制单元102、多个开关管103和多个充电芯片104。Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a multi-chip charging apparatus according to an embodiment of the present invention.

具体的,该电源输入接口101可以是终端上的USB接口。举例来说,USB接口可以连接充电器或移动电源等能提供电源的设备,以使该设备通过该USB接口将充电电流传输至目标充电芯片以对电池11进行充电。Specifically, the power input interface 101 can be a USB interface on the terminal. For example, the USB interface can be connected to a device capable of providing power such as a charger or a mobile power source, so that the device transmits a charging current to the target charging chip through the USB interface to charge the battery 11.

控制单元102,用于根据电池11的当前需求电量,从多个充电芯片104中确定目标充电芯片。The control unit 102 is configured to determine a target charging chip from the plurality of charging chips 104 according to the current required power of the battery 11.

需要说明的是,控制单元102可以是中央处理器(Central Processing Unit,CPU)或者微控制单元(Microcontroller Unit,MCU)等。在一种实现方式中,该控制单元102还可以包括硬件芯片,该硬件芯片可以是专用集成电路(Application-Specific Integrated Circuit,ASIC)或可编程逻辑器件(Programmable Logic Device,PLD)等。该PLD可以是现场可编程逻辑门阵列(Field-Programmable Gate Array,FPGA)或通用阵列逻辑(Generic Array Logic,GAL)等。在一种实现方式中,该控制单元102还可以包括存储装置,该存储装置可以用于存储电池11的当前需求电量或者存储控制单元102确定 的目标充电芯片的结果。具体的,该存储装置可以是易失性存储器(volatile memory),例如随机存取存储器(Random-Access Memory,RAM);该存储装置也可以是非易失性存储器(non-volatile memory),例如快闪存储器(flash memory)或固态硬盘(Solid-State Drive,SSD)等;该存储装置还可以是上述种类的存储器的组合。It should be noted that the control unit 102 may be a central processing unit (CPU) or a micro control unit (MCU). In an implementation manner, the control unit 102 may further include a hardware chip, which may be an Application-Specific Integrated Circuit (ASIC) or a Programmable Logic Device (PLD). The PLD may be a Field-Programmable Gate Array (FPGA) or a Generic Array Logic (GAL). In an implementation, the control unit 102 may further include a storage device, which may be used to store the current required power of the battery 11 or the storage control unit 102 determines The result of the target charging chip. Specifically, the storage device may be a volatile memory, such as a random access memory (RAM); the storage device may also be a non-volatile memory, such as a fast A flash memory or a solid state drive (SSD) or the like; the storage device may also be a combination of the above types of memories.

还需要说明的是,当前需求电量是电池11从充电开始到电池11充满的过程中所充的电量,即电池11的当前需求电量是电池11的总容量和电池11的当前电量之差。具体的,控制单元102可以直接检测电池11的当前需求电量。在一种实现方式中,控制单元102可以通过检测电池11的总容量和当前电量,来获取当前需求电量。还需要特别说明的是,当前需求电量可以是以安培·小时(A·H)为单位的绝对电量值,也可以是以百分比来衡量的相对电量值。It should also be noted that the current required power is the amount of power charged by the battery 11 from the start of charging to the full charge of the battery 11, that is, the current required power of the battery 11 is the difference between the total capacity of the battery 11 and the current power of the battery 11. Specifically, the control unit 102 can directly detect the current demanded power of the battery 11. In one implementation, the control unit 102 can obtain the current demanded power by detecting the total capacity of the battery 11 and the current amount of power. It should also be noted that the current demanded power can be the absolute power value in ampere-hours (A·H), or the relative power value measured in percentage.

具体的,控制单元102根据电池11的当前需求电量,从多个充电芯片104中确定目标充电芯片。Specifically, the control unit 102 determines the target charging chip from the plurality of charging chips 104 according to the current required power of the battery 11.

举例来说,当电池11的当前需求电量较少(如5%或10%等)时,控制单元102可以从多个充电芯片104中选择较少数量的充电芯片作为目标充电芯片,如1个充电芯片或者2个充电芯片。因为在电源输入接口101输出的充电电流值一定的情况下,不管采用多少个目标充电芯片对电池11进行充电,目标充电芯片输出的总电流大小是不变的,即对于电池11而言,其充电效率是一样的。但是,对于充电芯片而言,由于充电芯片属于电子器件,具有有限的寿命。充电芯片在充电过程中会产生热量,而产生的热量越多,对该充电芯片的损耗越大,即该充电芯片的寿命降低越快。并且在大电流充电方案中,这种发热现象更加严重,因此,其充电芯片的寿命也会降低的更快。因此,为了延长充电芯片的寿命,在电池的当前需求电量较小的时候,可以选择较少的目标充电芯片对电池进行充电。其中,大电流充电技术是一种为实现快速充电(简称快充)而提出的技术。一般来说,充电功率超过10W(也就是5V 2A)就能称之为快充,即充电电流大于或等于2A就能称之为大电流充电。For example, when the current demanded power of the battery 11 is small (such as 5% or 10%, etc.), the control unit 102 may select a smaller number of charging chips from the plurality of charging chips 104 as the target charging chip, such as 1 Charge chip or 2 charging chips. Because the charging current value outputted by the power input interface 101 is constant, regardless of how many target charging chips are used to charge the battery 11, the total current output by the target charging chip is constant, that is, for the battery 11, The charging efficiency is the same. However, for a charging chip, since the charging chip belongs to an electronic device, it has a limited life. The charging chip generates heat during charging, and the more heat generated, the greater the loss to the charging chip, that is, the faster the life of the charging chip decreases. And in the high current charging scheme, this heating phenomenon is more serious, and therefore, the life of the charging chip is also reduced more quickly. Therefore, in order to extend the life of the charging chip, when the current battery demand is small, a smaller target charging chip can be selected to charge the battery. Among them, the high current charging technology is a technology proposed for realizing fast charging (referred to as fast charging). In general, charging power exceeding 10W (that is, 5V 2A) can be called fast charging, that is, charging current greater than or equal to 2A can be called high current charging.

又举例来说,当电池11的当前需求电量较多(如80%或90%等)时,控制单元102可以从多个充电芯片104中选择较多数量的充电芯片作为目标充电芯片。这是因为随着温度增加,电子器件(如充电芯片)的失效率呈指数增大。举例来说,若电源输入接口101输出的充电电流为4A(大电流充电),电池 11的当前需求电量为90%时,控制单元102选择一个充电芯片1041对电池11进行充电,若该充电芯片1041的内阻为R,那么该充电芯片1041在充电过程中产生的损耗为16R,且该损耗大部分均以热量的形式散发,就会使得该充电芯片1041的温度急剧升高,使得该充电芯片1041的失效率快速增大,导致充电效率降低,影响用户体验。但若该控制单元102选择4个充电芯片1041、1042、1043和1044对电池11进行充电,且各个充电芯片的内阻均为R,即均分到各个充电芯片上的充电电流为1A,那么该4个充电芯片在充电过程中产生的损耗均为R,即该4个充电芯片在充电过程中产生的总损耗为4R。相应的,产生的总热量也会大幅度减少,从而大大提高充电芯片的平均寿命,进而提高电池的充电效率,提高用户体验。因此,为了均衡每个充电芯片的寿命,在电池11的当前需求电量较多时,可以选择较多的充电芯片对电池11进行充电。For another example, when the battery 11 currently has a large amount of power (such as 80% or 90%, etc.), the control unit 102 can select a larger number of charging chips from the plurality of charging chips 104 as the target charging chip. This is because as the temperature increases, the failure rate of electronic devices (such as charging chips) increases exponentially. For example, if the charging current output by the power input interface 101 is 4A (high current charging), the battery When the current required power of 11 is 90%, the control unit 102 selects a charging chip 1041 to charge the battery 11. If the internal resistance of the charging chip 1041 is R, the charging chip 1041 generates a loss of 16R during charging. Moreover, the loss is mostly dissipated in the form of heat, which causes the temperature of the charging chip 1041 to rise sharply, so that the failure rate of the charging chip 1041 is rapidly increased, resulting in a decrease in charging efficiency and affecting the user experience. However, if the control unit 102 selects four charging chips 1041, 1042, 1043, and 1044 to charge the battery 11, and the internal resistance of each charging chip is R, that is, the charging current equally distributed to each charging chip is 1A, then The losses generated by the four charging chips during the charging process are all R, that is, the total loss generated by the four charging chips during charging is 4R. Correspondingly, the total heat generated is also greatly reduced, thereby greatly increasing the average life of the charging chip, thereby improving the charging efficiency of the battery and improving the user experience. Therefore, in order to balance the life of each charging chip, when the current demanded power of the battery 11 is large, more charging chips can be selected to charge the battery 11.

在一种实现方式中,控制单元102可以根据电池11的当前需求电量,确定所需的充电芯片的数量,然后在多个充电芯片104中选择该数量的充电芯片作为目标充电芯片。需要说明的是,控制单元102在多个充电芯片104中选择该数量的充电芯片作为目标充电芯片的选择方式可以是随机选择,可以是根据充电芯片的位置选择,也可以是根据充电芯片的状态参数进行选择,该状态参数可以是充电芯片的当前温度值或总工作时长等。In an implementation manner, the control unit 102 may determine the required number of charging chips according to the current required power of the battery 11, and then select the number of charging chips as the target charging chip among the plurality of charging chips 104. It should be noted that the selection manner in which the control unit 102 selects the number of charging chips as the target charging chip among the plurality of charging chips 104 may be randomly selected, may be selected according to the position of the charging chip, or may be according to the state of the charging chip.
