[0015] 即使仅并联连接的电池中的一个发生故障,所有电池都不能使用。 [0015] Even if only a parallel connection of the battery fails, all batteries can not be used.

[0016] 为了解决这些限制,对每个电池而言,诸如正温度系数(PTC)、温度补偿电路、或额外电路的保护单元24是必需的。 [0016] To address these limitations, for each cell, the protection unit such as a positive temperature coefficient (PTC), a temperature compensation circuit, or additional circuitry 24 is required. [0017] 因此,由于使用额外的保护单元,所以不推荐使用并联连接的电池。 [0017] Thus, the use of additional protection unit, it is not recommended to use batteries connected in parallel.

[0084] 不必说,PWM控制器可以设置在控制器的外部侧,或控制器本身起PWM控制器的作用。 [0084] Needless to say, PWM control can be set in the external side of the controller, or the controller itself functions as a PWM controller.

[0086] 图7是示出在没有电流平衡单元(图6的64)的控制的情况下电源单元的每个电源中的电流充电的框图700。 [0086] FIG. 7 is a graph showing each power supply unit in the block diagram of the charging current of 700 in the absence of current balance unit (64 in FIG. 6) of the control case.

[0088] 当电流被充入各个电池时,由于各个电池之间的阻抗差而产生各个电池的充电电流之间的差。 [0088] When a current is charged into each battery, since the impedance difference between each battery and produce a difference of each battery charge current. 例如,电池71a以70mA进行充电,电池71b以80mA进行充电,以及电池71c以90mA进行充电。 For example, 70mA battery 71a to be charged, for charging the battery 71b to 80mA, and 90mA for charging the battery 71c with.

[0089] 在以上描述中,尽管示例性地解释了充电电流,但是放电电流也同样适用。 [0089] In the above description, although an example explains the charging current, but also applies the discharge current.

[0091] 除了在充电器和电源单元之间提供电流平衡单元84并且提供用来控制电流平衡单元和电源单元81的微型计算机87之外,图8的实施例类似于图7的实施例。 [0091] In addition to the power supply unit provided between the charger and the current balance unit 84 and provides means for controlling the current balance and the power supply unit 81 outside the microcomputer 87, the embodiment of Figure 8 is similar to the embodiment of FIG.

[0092] 因此,控制器根据电源单元的各个电池81a、81b、和81c的充电/放电电流量的识别结果控制电流平衡单元84的PWM占空开关84a、84b和84c以使各个电池的充电/放电电流平衡。 [0092] Thus, the controller controls the current balance of each unit based on the recognized rechargeable battery power supply units 81a, 81b, and 81c / discharge current amount of PWM 84 duty switches 84a, 84b and 84c so that each battery charge / discharge current balance.

[0093] 图9a、%、和9c是示出按脉冲宽度控制的电源之间电流平衡的曲线图,所述脉冲宽度的控制通过图8的电流平衡单元84的PWM占空开关84a、84b、和84c中的每一个的控制来启动。 [0093] Figure 9a,%, and 9c is a graph showing a pulse-width control between the supply current balance graph, the pulse width of the control unit 8 through FIG current balance of the duty cycle PWM 84 switches 84a, 84b, and control 84c each to start.

[0094] 如图9a中所示,在图8的电池81a中,被施加功率的波形的原始时钟周期的100%被应用,作为PWM开关84a的接通持续时间,从而使得PWM的占空比被控制到100 %,并且因此电池81b以70mA进行充电。 100% [0094] As shown in Fig. 9a, 81a 8 in FIG battery, the power is applied to the waveform of the original clock cycles is applied, the duration of a PWM switch 84a is turned on, such that the duty cycle of PWM It is controlled to 100%, and thus the battery 81b is charged to 70mA.

[0095] 如图9b中所示,在图8的电池81b中,被施加功率的波形的原始时钟周期的87.5%被应用作PWM占空开关84b的接通持续时间,使得PWM的占空比被控制到87.5%,并且因此电池81a以70mA进行充电。 87.5% [0095] As shown in Figure 9b, 81b 8 in view of the battery, the power is applied to the waveform of the original clock cycles to be applied for the duty cycle of the PWM duty cycle switch is turned 84b duration, so the PWM It is controlled to 87.5%, and thus the battery 81a is charged to 70mA.

[0096] 如图9c中所示,在图8的电池81c中,被施加功率的波形的原始时钟周期的77.7%被应用作PWM占空开关84c的接通持续时间,使得PWM的占空比被控制到77.7%,并且因此电池81c以70mA进行充电。 77.7% [0096] As shown in FIG. 9c, 81c 8 in view of the battery, the power is applied to the waveform of the original clock period is the duty cycle of the PWM duty cycle applied as a switch 84c is turned on duration, so that the PWM It is controlled to 77.7%, and thus charging the battery 81c to 70mA.

[0097] 如上所述,通过控制PWM占空开关的接通/断开持续时间来控制PWM占空比(100%,87.5%和77.7% ),由此使各个电池的充电/放电电流平衡。 [0097] As described above, by controlling the PWM duty turning the switch ON / OFF control of the PWM duty cycle duration (100%, 87.5% and 77.7%), whereby each of the battery charging / discharging current balance.

[0098] 同时,当控制在并联连接的电池的放电操作中的PWM占空比时,控制所述PWM占空比使得电池中的至少一个被放电。 [0098] Meanwhile, when the control in the parallel connection of the battery discharge operation in the PWM duty cycle of the PWM duty cycle control such that at least one battery is discharged. 即,控制所述PWM占空比使得在特定的时间点并联连接的所有电池的放电没有被断开,由此稳定地将电流施加到系统。 I.e., controlling the duty cycle of the PWM such that all the cells in a specific point in time has not been connected in parallel to the discharge disconnected, thereby stably applying a current to the system.

[0099] 图10是根据另一实施例的流程图。 [0099] FIG. 10 is a flowchart of another embodiment in accordance with.

[0100] 图10的流程图100示出,根据各个电池61a、61b、和61c的充电/放电电流量或各个电池的阻抗的识别结果通过控制器69控制PWM占空开关64a、64b和64c的接通/断开持续时间以便控制PWM的占空比(100%、87.5%和77.7% ),由此使各个电池的充电/放电 [0100] FIG. 10 shows a flowchart 100, according to each cell 61a, the recognition result 61b, and 61c of the charging / discharging current amount of each battery impedance or PWM duty cycle by the controller 69 controls the switch 64a, 64b and 64c of on / off control for the duration of the duty cycle of the PWM (100%, 87.5% and 77.7%), whereby each battery charging / discharging

电流平衡。 Current balance.

[0101] 在图10的操作中,除了其中根据各个电池61a、61b和61c的充电/放电电流量或各个电池的阻抗的识别结果通过控制器69控制PWM占空开关64a、64b和64c的接通/断开持续时间以便控制PWM的占空比(100%、87.5%和77.7% )的操作SlOll之外,所有操作与图4和5的操作基本相同并且因此在此将省略其描述。 [0101] In the operation of FIG. 10, in addition to which the individual battery according 61a, 61b recognition result and 61c of the charging / discharging amount of current or the impedance of each battery via the controller 69 controls the PWM duty switches 64a, 64b and 64c are connected on / off control for the duration of the duty cycle of the PWM (100%, 87.5% and 77.7%) than the operation SlOll, operating all operations of FIG. 4 and 5 is substantially the same and thus description will be omitted here.

[0102] 同时,在图4、5、和10的实施例中,尽管控制器根据各个电池的充电或放电电流示例性地控制电流平衡单元,但是本公开并不限于此配置。 [0102] Meanwhile, in FIG. 4, 5, and 10 of the embodiment, although the controller controls the current example the respective cell balancing unit according to the charge or discharge current, but the present disclosure is not limited to this configuration. 例如,控制器可以根据各个电池的阻抗控制电流平衡单元。 For example, the controller may control the current balancing means according to the respective impedance of the battery.

[0103] 如前所述,根据本公开的用来控制功率的设备和方法,为了在电池被并联连接的状态中使各个电池的充电电流或放电电流中的至少一个匹配,诸如可变电阻器的电流平衡部件被串联连接到各个电池,使得各个电池的所有阻抗彼此匹配,而不论电池的特性如何。 [0103] As described above, according to the present disclosure an apparatus and method for power control, the state of the battery to be connected in parallel manipulation of at least one match of each battery charging current or discharging current, such as a variable resistor The current balance components are connected in series to each cell, so that each cell of all impedance matching each other, but regardless of how the characteristics of the battery.

[0104] 另外,本公开涉及用来控制功率的设备和方法,所述设备和方法可以通过将可变电阻器串联连接到各个电池来利用控制器控制功率以便在电池并联连接的状态中使各个电池的阻抗彼此匹配。 [0104] Further, the present disclosure relates to apparatus and method for controlling power, the apparatus and method can be achieved by a variable resistor connected in series to each cell in order to use the controller controls the power state of each battery connected in parallel manipulation battery impedance match each other.

[0105] 另外,本公开涉及用来控制功率的设备和方法,所述设备和方法可以在考虑各个电池的特性的情况下通过控制诸如连接到各个电池的可变电阻器的电流平衡部件来使阻抗匹配。 [0105] In addition, the present disclosure relates to an apparatus and method for controlling power, the apparatus and method may be considered in the characteristics of each cell by controlling such a case connected to each cell variable resistor current balancing components to make impedance matching.

[0106] 各个电池的匹配阻抗是每个电池的内部阻抗和每个可变电阻器的阻抗的和。 [0106] matching the impedance of each cell is an internal impedance of each cell and the variable resistor and the impedance of each.

[0107] 根据本公开,根据各个电池的充电/放电电流的监测结果通过微型计算机控制电流平衡单元使得各个电池的阻抗彼此匹配,由此均一地控制充电/放电电流。 [0107] According to the present disclosure, based on the monitoring results of each battery charge / discharge current is controlled by the microcomputer unit current balance such that each cell impedance matched with each other, thereby uniformly control the charge / discharge current.

[0108] 因此,能够使用多个并联连接的电池并且可以选择性地省略PTC和温度补偿电路。 [0108] Thus, it is possible to use a plurality of batteries connected in parallel and may be selectively omitted PTC and temperature compensation circuitry. 因此,可以降低生产成本。 Accordingly, the production cost can be reduced.

[0109] 另外,因为电池被独立地控制,所以可以防止由相关技术的多电池的环路程差和电池阻抗匹配缺陷引起的功能退化。 [0109] Further, because the battery is independently controlled, so that the function can be prevented by the multi-cell battery impedance matching ring path length difference and disadvantages of the related art due to degradation.

[0110] 根据上述实施例,通过以下方法来平衡处于电池被并联连接的状态中的各个电池的充电/放电电流:1)在识别并联连接的各个电池的充电或/和放电电流之后通过PWM占空比或诸如可变电阻器的电流平衡单元的控制来匹配各个电池的阻抗或2)控制电池使得在识别各个电池的电流阻抗之后利用电流平衡单元使电池的阻抗彼此匹配。 [0110] According to the above embodiment, by the following method to balance the state of charge of the battery are connected in parallel in each battery / discharge current: 1) After identifying the respective parallel-connected battery charging and / or discharging current by the PWM duty control cycle, such as a variable resistor or a current balance unit to match the impedance of individual cells or 2) such that after recognition to control the battery current impedance of each battery cell of the battery with a current balancing impedance matched with each other.
