本发明进一步提供一种终端电池，参见图1，图1是本发明的终端电池一实施例的功能模块示意图。在本实施例中，终端电池100包括：电池阵列单元110和阵列控制单元120。电池阵列单元110包括至少两个电池。阵列控制单元120，用于当电池阵列单元110处于充电状态时，控制电池阵列单元110内的所有电池以并联的方式电连接；以及当电池阵列单元110处于非充电状态时，控制电池阵列单元110内的所有电池以串联的方式电连接。The present invention further provides a terminal battery. Referring to FIG. 1 , FIG. 1 is a schematic diagram of functional modules of an embodiment of the terminal battery of the present invention. In this embodiment, the terminal battery 100 includes: a battery array unit 110 and an array control unit 120 . The battery array unit 110 includes at least two batteries. The array control unit 120 is used to control all batteries in the battery array unit 110 to be electrically connected in parallel when the battery array unit 110 is in a charging state; and to control the battery array unit 110 when the battery array unit 110 is in a non-charging state. All cells within are electrically connected in series.
所述阵列控制单元120，具体用于在所述电池阵列单元110处于充电状态时，根据充电电源输入的充电电压触发将所述电池阵列单元110内的所有电池以并联的方式电连接。即在本实施例中可为充电器的充电电源与终端连接后，充电器与终端电池100的阵列控制单元120实现电连接，此时充电器向阵列控制单元120输入电压信号，电池阵列单元120根据充电器的输入电压信号(5V电压信号)，触发将电池阵列单元110内的所有电池以并联的方式电连接。另外由于充电器的输入电压高于电池阵列单元110的充电电压，本实施例在所述终端内部设置有buck电压变换电路；充电器连接终端后，buck电压变换电路的电压输入端与充电器的电压输入端电连接，buck电压变换电路的电压输出端与电池陈列单元110电连接，使得在充电过程中充电器向buck电压变换电路输入的高电压，通过buck电压变换电路变换为低电压，然后由buck电压变换电路电压输出端向电池阵列单元110输入低电压。The array control unit 120 is specifically configured to trigger electrical connection of all the batteries in the battery array unit 110 in parallel according to the charging voltage input by the charging power source when the battery array unit 110 is in a charging state. That is, in this embodiment, after the charging power source of the charger is connected to the terminal, the charger is electrically connected to the array control unit 120 of the terminal battery 100. At this time, the charger inputs a voltage signal to the array control unit 120, and the battery array unit 120 According to the input voltage signal (5V voltage signal) of the charger, all the batteries in the battery array unit 110 are triggered to be electrically connected in parallel. In addition, since the input voltage of the charger is higher than the charging voltage of the battery array unit 110, a buck voltage conversion circuit is provided inside the terminal in this embodiment; after the charger is connected to the terminal, the voltage input terminal of the buck voltage conversion circuit is connected to the The voltage input terminal is electrically connected, and the voltage output terminal of the buck voltage conversion circuit is electrically connected to the battery display unit 110, so that during the charging process, the high voltage input by the charger to the buck voltage conversion circuit is converted into a low voltage by the buck voltage conversion circuit, and then A low voltage is input to the battery array unit 110 from the voltage output terminal of the buck voltage conversion circuit.
本实施例在对电池阵列单元110进行充电时，通过将电池阵列单元110内的所有电池以并联的方式电连接，能够降低电池阵列单元110的充电电压，电池阵列单元110的充电电压降低后，随着充电时间的增加，电池阵列单元110的充电电压上升速度缓慢，因而电池阵列单元110的充电阻抗上升速度缓慢，电池阵列单元110不会出现因此充电阻抗过大导致充电异常截止，而无法充满电的现象。同时由于电池阵列单元110的充电电压低，因此电池阵列单元110的充电电路不会受到充电电压的影响而损坏。In this embodiment, when charging the battery array unit 110, by electrically connecting all the batteries in the battery array unit 110 in parallel, the charging voltage of the battery array unit 110 can be reduced. After the charging voltage of the battery array unit 110 is reduced, As the charging time increases, the charging voltage of the battery array unit 110 rises slowly, so the charging impedance of the battery array unit 110 rises slowly, and the battery array unit 110 will not appear. Therefore, the charging impedance is too large and the charging is abnormally cut off, so it cannot be fully charged. The phenomenon of electricity. At the same time, because the charging voltage of the battery array unit 110 is low, the charging circuit of the battery array unit 110 will not be damaged due to the influence of the charging voltage.
本实施例中所述电池阵列单元110非充电状态包括：电池阵列单元110放电状态、电池阵列单元110不放电不供电状态(终端关机状态)，即所述阵列控制单元120在充电器不再向其输入电压信号的初始时刻，将所述电池阵列单元内的所有电池从并联的电连接的方式转换为以串联的方式电连接，并一直维持所有电池以串联的方式电连接，直至充电器向其再次输入电压信号。The non-charging state of the battery array unit 110 in this embodiment includes: the discharging state of the battery array unit 110, the state of the battery array unit 110 not discharging and not supplying power (terminal shutdown state), that is, the array control unit 120 is no longer charging to the battery array unit 120. At the initial moment of its input voltage signal, all the batteries in the battery array unit are converted from the parallel electrical connection to the series electrical connection, and maintain all the batteries in the series electrical connection until the charger is connected to the battery. It inputs a voltage signal again.
本实施例中，在电池阵列单元110放电(电池阵列单元110为终端供电)时，通过将电池阵列单元110内的所有电池以串联的方式电连接，能够升高电池阵列单元110的放电电压，以满足终端正常用电的需求。In this embodiment, when the battery array unit 110 is discharging (the battery array unit 110 supplies power to the terminal), by electrically connecting all the batteries in the battery array unit 110 in series, the discharge voltage of the battery array unit 110 can be increased, To meet the needs of the normal power consumption of the terminal.
参见图2，图2是图1中电池阵列单元的电路结构示意图，其中，图2的以两个电池为例对本发明实施例中的电池阵列单元的串联、并联方式进行举例说明。本实例中所述电池阵列单元110包括两个电池，具体包括：第一电池BAT1、第二电池BAT2、第一开关K1、第二开关K2、第三开关K3。所述第一电池BAT1的正极分别与所述第一开关K1的第一端1、所述第二开关K2的第一端1连接，所述第一电池BAT1的负极分别与所述第三开关K3的第一端1、以及地连接；所述第二电池BAT2的正极分别与所述第一开关K1的第二端2以及电压输入/输出端连接，所述第二电池BAT2的负极分别与所述第二开关K2的第二端2、以及所述第三开关K3的第二端2连接。其中，所述电压输入/输出端为：当终端电池处于充电状态下为电压输入端，当终端电池处于放电状态下为电压输出端。所述阵列控制单元120，具体用于当电池阵列单元110处于充电状态时，控制第一开关K1、第三开关K3处于闭合状态，第二开关K2处于断开状态，即此时第一电池BAT1和第二电池BAT2以并联的方式电连接；以及当电池阵列单元110处于非充电状态时，控制第一开关K1、第三开关K3处于断开状态，第二开关K2处于闭合状态，即此时第一电池BAT1和第二电池BAT2以串联的方式电连接。Referring to FIG. 2 , FIG. 2 is a schematic diagram of the circuit structure of the battery array unit in FIG. 1 . In FIG. 2 , two batteries are taken as an example to illustrate the series and parallel connection of the battery array unit in the embodiment of the present invention. The battery array unit 110 in this example includes two batteries, specifically: a first battery BAT1, a second battery BAT2, a first switch K1, a second switch K2, and a third switch K3. The positive pole of the first battery BAT1 is respectively connected to the first terminal 1 of the first switch K1 and the first terminal 1 of the second switch K2, and the negative pole of the first battery BAT1 is respectively connected to the third switch The first terminal 1 of K3 is connected to ground; the positive pole of the second battery BAT2 is connected to the second terminal 2 of the first switch K1 and the voltage input/output terminal respectively, and the negative pole of the second battery BAT2 is connected to the voltage input/output terminal respectively. The second terminal 2 of the second switch K2 is connected to the second terminal 2 of the third switch K3. Wherein, the voltage input/output end is: when the terminal battery is in a charging state, it is a voltage input end, and when the terminal battery is in a discharging state, it is a voltage output end. The array control unit 120 is specifically configured to control the first switch K1 and the third switch K3 to be in the closed state and the second switch K2 to be in the open state when the battery array unit 110 is in the charging state, that is, at this time the first battery BAT1 and the second battery BAT2 are electrically connected in parallel; and when the battery array unit 110 is in a non-charging state, the first switch K1 and the third switch K3 are controlled to be in an open state, and the second switch K2 is in a closed state, that is, at this time The first battery BAT1 and the second battery BAT2 are electrically connected in series.
本发明提出终端电池另一实施例，本实施例在上述实施例的基础上进行了改进，改进之处在于：当电池阵列单元110处于充电状态时，由充电电源向终端供电。所述阵列控制单元120，还用于当充电电源向终端供电的电量少于终端工作所需电量时，切换所述电池阵列单元110内的所有电池以串联的方式电连接，以使所述充电电源与所述电池阵列单元110同时向所述终端供电，以满足终端工作所需电量。即当充电电源向终端供电的电量少于终端工作所需电量时，由阵列控制单元120将电池阵列单元110内所有电池由并联的电连接方式切换为串联的电连接方式。此时充电电源不再向电池阵列单元110充电，只为终端供电，并由电池阵列单元110为终端续流。The present invention proposes another embodiment of the terminal battery. This embodiment is improved on the basis of the above-mentioned embodiments. The improvement lies in that when the battery array unit 110 is in a charging state, the charging power supply supplies power to the terminal. The array control unit 120 is also used to switch all the batteries in the battery array unit 110 to be electrically connected in series when the power supplied by the charging power supply to the terminal is less than the power required for the terminal to make the charging The power supply and the battery array unit 110 supply power to the terminal at the same time, so as to meet the power required for the terminal to work. That is, when the power supplied by the charging power source to the terminal is less than the power required for the terminal to work, the array control unit 120 switches all the batteries in the battery array unit 110 from a parallel electrical connection to a series electrical connection. At this time, the charging power supply no longer charges the battery array unit 110, but only supplies power to the terminal, and the battery array unit 110 continues the current flow for the terminal.
本发明所提供的终端电池100实施例，通过当电池阵列单元110处于充电状态时，控制所述电池阵列单元110内的所有电池以并联的方式电连接；当电池阵列单元110处于非充电状态时，控制所述电池阵列单元110内的所有电池以串联的方式电连接的方式，降低了电池阵列单元110的充电输入电压，在充电过程中，电池阵列单元110的充电电压上升速度缓慢，因而充电阻抗上升速度缓慢，不会出现因此充电阻抗过大导致充电异常截止，而无法充满电的现象，能够在保证终端电池100容量高前提下，缩短终端电池100的充电时间(提高终端电池100的充电速度)。同时相比高压充电电池，本发明的终端电池100无需采用高压电芯，电池阵列单元110的充电电路不会受到高压充电的影响而损坏，终端电池100的制作成本更低，使用寿命更长。In the embodiment of the terminal battery 100 provided by the present invention, when the battery array unit 110 is in the charging state, all the batteries in the battery array unit 110 are controlled to be electrically connected in parallel; when the battery array unit 110 is in the non-charging state , controlling all the batteries in the battery array unit 110 to be electrically connected in series reduces the charging input voltage of the battery array unit 110. During the charging process, the charging voltage of the battery array unit 110 rises slowly, thus charging Impedance rising speed is slow, so there will be no phenomenon that the charging impedance is too large to cause abnormal charging cut-off, and cannot be fully charged.
