For example, some steps can be decomposed, and some steps can be combined or partially combined. Therefore, the actual execution order may be changed according to actual conditions. Fig. 1 shows a schematic diagram of a multi-source battery pack system according to an embodiment of the present invention. The multi-source battery pack system includes a plurality of battery packs ( numbers 111 and 112 in FIG. 1), a plurality of battery controllers ( numbers 112 and 122 in FIG. 1), a signal processing module 130 and a function module 140.

The battery controller may be, for example, a battery management system (BMS), and the present invention is not limited to this.
信号处理模块130与所述多个电池控制器通信连接。在本发明的一些具体实现中，信号处理模块130与各电池控制器之间还可以耦合信号输入/输入端口和/或简单的信号预处理，本发明并非以此为限。所述信号处理模块130将多个电池控制器的输出信号合并为输入到功能模块140的一个输入信号。在本实施例中，所述信号处理模块130将所述功能模块140的输出信号拆分为分别输入到多个电池控制器的多个输入信号。The signal processing module 130 is in communication connection with the plurality of battery controllers. In some specific implementations of the present invention, signal input/input ports and/or simple signal preprocessing may be coupled between the signal processing module 130 and each battery controller, and the present invention is not limited to this. The signal processing module 130 combines the output signals of multiple battery controllers into one input signal input to the functional module 140. In this embodiment, the signal processing module 130 splits the output signal of the function module 140 into multiple input signals respectively input to multiple battery controllers.
功能模块140与所述信号处理模块130通信连接。在本实施例中，功能模块140例如为整车控制器的功能模块。功能模块140用于实现整车定义的各种整车控制器功能，比如整车上下电、整车换挡、扭矩驱动等。The function module 140 is in communication connection with the signal processing module 130. In this embodiment, the functional module 140 is, for example, a functional module of a vehicle controller. The function module 140 is used to implement various vehicle controller functions defined by the vehicle, such as powering on and off the vehicle, gear shifting, torque driving, and so on.
在图1所示的实施例中，多源电池包***还包括其它控制器150(其它控制器包括电机控制器、OBC充电控制器等车上参与控制的其它控制器)。其它控制器150也可以通过直接与信号处理模块130通信连接，从而与电池控制器通信。In the embodiment shown in FIG. 1, the multi-source battery pack system further includes other controllers 150 (the other controllers include motor controllers, OBC charging controllers and other controllers participating in the control of the vehicle). Other controllers 150 can also communicate with the battery controller by directly communicating with the signal processing module 130.
下面以其它控制器150也可以通过直接与信号处理模块130通信连接，从而与电池控制器通信为例，描述本发明的具体实施例。In the following, a specific embodiment of the present invention will be described by taking other controllers 150 that can communicate with the battery controller through direct communication with the signal processing module 130 as an example.
在本实施例中，其它控制器150和所述功能模块140之间还可以耦合其它控制器输入/输出模块，以将其它控制器150与整车控制器各功能模块140有关的信号输入到整车控制器至整车控制器的功能模块140；将其它控制器150与电池控制器有关的信号输入到信号处理模块130，已经由信号处理模块130处理从而发送至电池控制器；将整车控制器各功能模块140输入的信号输出给其它控制器150；将信号处理模块130输入的信号输出给其他控制器150。功能模块140用于将跟电池控制器有关的信号输出给信号处理模块130；将跟其他控制器150有关的信号输出至其它控制器输入/输出模块。In this embodiment, other controller input/output modules may also be coupled between the other controller 150 and the functional module 140 to input signals related to the other controller 150 and the functional modules 140 of the vehicle controller to the entire vehicle. The functional module 140 from the vehicle controller to the vehicle controller; input signals related to the battery controller from other controllers 150 to the signal processing module 130, which have been processed by the signal processing module 130 and sent to the battery controller; the vehicle is controlled The signals input by the functional modules 140 of the controller are output to other controllers 150; the signals input by the signal processing module 130 are output to other controllers 150. The function module 140 is used to output signals related to the battery controller to the signal processing module 130; to output signals related to other controllers 150 to other controller input/output modules.
信号处理模块130用于将电池控制器A112和电池控制器B122相同类型的信号合并为一个信号，然后，再将这合并后的信号中与整车控制器的功能模块140有关的信号输出给整车控制器的功能模块140，与其它控制器150有关的信号输出至其它控制器输入/输出模块；将整车控制器的功能模块140 输入的信号拆分成两个信号，分别输出给电池控制器A112和电池控制器B122；将其它控制器输入/输出模块输入的信号拆分成两个信号、分别输出给电池控制器A112和电池控制器B122。The signal processing module 130 is used to combine the same types of signals of the battery controller A112 and the battery controller B122 into one signal, and then output the signals related to the functional module 140 of the vehicle controller in the combined signal to the whole vehicle controller. The function module 140 of the vehicle controller outputs signals related to other controllers 150 to the input/output modules of other controllers; the signal input by the function module 140 of the vehicle controller is split into two signals, which are respectively output to the battery control A112 and a battery controller B122; split the signal input from other controller input/output modules into two signals, which are output to the battery controller A112 and the battery controller B122 respectively.
具体而言，由于多源电池包电动汽车动力***有多个电池包，相应有多个电池控制器，如果按照传统方式，以两个电池控制器、整车控制器以及其它控制器挂彼此之间相互交互的架构方式进行控制，则整车控制器以及其它控制器要跟多个电池控制器相互交互，显而易见地，单电池包平台的整车控制器和其它控制器的软件没法适用，须重新开发软件才能满足需求，因为单电池包平台的整车控制器和其它控制器都是只跟一个电池控制器交互。Specifically, because the multi-source battery pack electric vehicle power system has multiple battery packs, there are correspondingly multiple battery controllers. If in the traditional way, two battery controllers, vehicle controllers and other controllers are connected to each other. If the vehicle controller and other controllers interact with multiple battery controllers, obviously, the software of the vehicle controller and other controllers of the single battery pack platform cannot be applied. The software must be re-developed to meet the demand, because the vehicle controller and other controllers of the single battery pack platform only interact with one battery controller.
本发明中，通过在多个电池控制器跟整车控制器和其它控制器交互之前，先对两个电池控制器的信号进行处理，将类型相同的两个信号处理成一个信号(如将电池包A111的电池控制器A112发的信号高压连接状态HvConnect_A和电池包B121的电池控制器B122发的信号高压连接状态HvConnect_B处理成一个信号HvConnect)，相当于两个电池控制器变成了一个电池控制器，再跟整车控制器和其它控制器交互，则整车控制器和其它控制器就可以如单源电池包电动汽车平台(即单电池包电动汽车平台)的整车控制器和其它控制器一样，只用跟一个电池控制器交互，则多源电池包电动汽车平台的整车控制器软件和其他控制器的软件就可以沿用单源池包电动汽车平台的软件，只需再多开发一个信号处理模块。In the present invention, before the multiple battery controllers interact with the vehicle controller and other controllers, the signals of the two battery controllers are processed first, and the two signals of the same type are processed into one signal (such as the battery The high-voltage connection status HvConnect_A signal from the battery controller A112 of the package A111 and the high-voltage connection status HvConnect_B signal from the battery controller B122 of the battery package B121 are processed into a signal HvConnect), which is equivalent to two battery controllers becoming one battery control After interacting with the vehicle controller and other controllers, the vehicle controller and other controllers can be like the vehicle controller and other controls of the single-source battery pack electric vehicle platform (that is, the single battery pack electric vehicle platform) It only needs to interact with one battery controller, and the whole vehicle controller software of the multi-source battery pack electric vehicle platform and the software of other controllers can use the software of the single source battery pack electric vehicle platform, and only need to develop more A signal processing module.
本发明所述的***架构中，整车控制器包括信号处理模块、功能模块及信号传输模块(诸如其它控制器输入/输出模块)。In the system architecture of the present invention, the vehicle controller includes a signal processing module, a function module, and a signal transmission module (such as other controller input/output modules).
多个电池控制器只跟整车控制器的信号处理模块交互、不直接与其它控制器交互，且多个电池控制器的所有信号都进入整车控制器的信号处理模块，同时个电池控制器之间无交互；其它控制器与跟整车控制器的信号处理模块及功能模块交互，且其它控制器与电池控制器和整车控制器有关的信号都进入整车控制器的信号处理模块。Multiple battery controllers only interact with the signal processing module of the vehicle controller, not directly with other controllers, and all signals of multiple battery controllers enter the signal processing module of the vehicle controller, and a battery controller at the same time There is no interaction between them; other controllers interact with the signal processing modules and functional modules of the vehicle controller, and the signals related to other controllers, battery controllers and vehicle controllers all enter the signal processing module of the vehicle controller.
多个电池控制器的信号进入整车控制器的信号处理模块之后，不直接发送至整车控制器各功能模块，而是经过信号处理模块将多个电池控制器类型相同的信号处理成一个信号，然后再将这处理后的信号里与整车控制器的功能模块有关的信号输入给整车控制器的各功能模块，同时也将这处理后的信 号里与其它控制器有关的信号通过整车控制器的信号处理模块输出给其它控制器。After the signals of multiple battery controllers enter the signal processing module of the vehicle controller, they are not directly sent to the functional modules of the vehicle controller, but the signals of the same type of multiple battery controllers are processed into one signal through the signal processing module , And then input the signals related to the functional modules of the vehicle controller in the processed signal to the functional modules of the vehicle controller, and at the same time pass the signals related to other controllers in the processed signal The signal processing module of the vehicle controller outputs to other controllers.
其它控制器信号的信号进入整车控制器后，与整车控制器各功能模块有关的信号输入给整车控制器各功能模块，与电池控制器有关的信号输入给的信号处理模块，再由的信号处理模块处理成多个信号(如将电机母线电压信号MotVoltage处理成MotVotage_A和MotVoltage_B两个信号)，通过整车控制器分别输出给多个电池控制器。After the signals of other controller signals enter the vehicle controller, the signals related to the functional modules of the vehicle controller are input to the functional modules of the vehicle controller, and the signals related to the battery controller are input to the signal processing module, and then The signal processing module is processed into multiple signals (such as processing the motor bus voltage signal MotVoltage into two signals MotVotage_A and MotVoltage_B), which are output to multiple battery controllers through the vehicle controller.
整车控制器各功能模块输出的信号，与其它控制器有关的信号直接输出给其它控制器，与电池控制器有关的信号经由信号处理模块处理成多个信号、分别输出给多个电池控制器。The signals output by the functional modules of the vehicle controller, the signals related to other controllers are directly output to other controllers, and the signals related to the battery controller are processed into multiple signals through the signal processing module and output to multiple battery controllers. .
进一步地，在本实施例中，多源电池包***还包括充电桩160，充电桩160可以与所述信号处理模块130通信连接，并与多个电池包中的一个或多个电连接(图中为了清楚起见，未示出充电桩160与电池包A和/或电池包B电连接的连接线)。通过信号处理模块130获得的多个电池包的信息，从而确定充电电池包，信号处理模块130可以发出指示控制充电桩160与电池包的电连接，从而进行充电。该部分也可由独立于信号处理模块130的多源电池包充放电装置来执行，本发明并非以此为限。Further, in this embodiment, the multi-source battery pack system further includes a charging post 160, which can be communicatively connected with the signal processing module 130 and electrically connected to one or more of the multiple battery packs (Fig. For the sake of clarity, the connecting wires that electrically connect the charging pile 160 to the battery pack A and/or the battery pack B are not shown). The information of multiple battery packs obtained by the signal processing module 130 is used to determine the rechargeable battery pack, and the signal processing module 130 may issue an instruction to control the electrical connection of the charging pile 160 and the battery pack to perform charging. This part can also be performed by a multi-source battery pack charging and discharging device independent of the signal processing module 130, and the present invention is not limited to this.
由此，本发明提供的多源电池包***能够极大的缩短研发周期和节约资源，并且具有如下优势：Therefore, the multi-source battery pack system provided by the present invention can greatly shorten the development cycle and save resources, and has the following advantages:

Quickly expand to three-source, four-source and even more-source battery pack electric vehicles (each battery pack is charged and discharged separately).
下面参见图2，图2示出了根据本发明一实施例的多源电池包充放电方法中放电的流程图。多源电池包充放电方法包括如下步骤：Now referring to FIG. 2, FIG. 2 shows a flow chart of discharging in a charging and discharging method for a multi-source battery pack according to an embodiment of the present invention.

本发明提供的多源电池包充放电方法中，通过多个电池包的故障信息及剩余电量确定供电电池包，从而确定由信号处理模块执行的多个电池包的控制器输出/输入的信号的合并和拆分方式，无需对功能模块及其它控制器进行变更，以实现多源电池包的供电。一方面，通过多源电池包解决了充电桩的距离限制、电池包紧急故障等情况；另一方面，可以保留已有的单个电池包的功能模块及其它控制器，减少成本，也便于对已在行驶使用的单个电池包的电动汽车进行简单的调整以实现多源电池包的应用。In the multi-source battery pack charging and discharging method provided by the present invention, the power supply battery pack is determined based on the fault information and the remaining power of the multiple battery packs, thereby determining the signal output/input signal of the controller of the multiple battery packs executed by the signal processing module Combining and splitting methods do not need to change the functional modules and other controllers to realize the power supply of multi-source battery packs. On the one hand, the distance limitation of the charging pile and emergency failure of the battery pack can be solved through the multi-source battery pack; on the other hand, the functional modules and other controllers of the existing single battery pack can be retained, reducing the cost and making it easier to check A single battery pack electric vehicle used in driving is simply adjusted to realize the application of multi-source battery packs.
具体而言，在本发明的各个实施例中，通过上述方法确定供电电池包后，可将该供电电池包的电池控制器的输出信号作为输出给功能模块(和其它控制器)的输出信号，以实现多个电池控制器的输出信号的合并。Specifically, in each embodiment of the present invention, after the power supply battery pack is determined by the above method, the output signal of the battery controller of the power supply battery pack can be used as the output signal to the functional module (and other controllers), In order to achieve the combination of the output signals of multiple battery controllers.
在本发明的一些实施例中，所述步骤S240自一个或多个准供电电池包中确定供电电池包之后还包括如下步骤：使得所述多个电池包中除了所述供电电池包之外的其余电池包的通信连接的电池控制器的输入信号指示所述其余电池包不供电。In some embodiments of the present invention, the step S240 further includes the following step after determining the power supply battery pack from one or more quasi-power supply battery packs: making the battery packs of the plurality of battery packs except the power supply battery pack The input signal of the battery controller of the communication connection of the remaining battery packs indicates that the remaining battery packs do not supply power.

For example, the power supply priority of each battery pack is predetermined.

Therefore, when both battery pack A and battery pack B are quasi-power supply battery packs, battery pack A is selected As a power supply battery pack.
在本发明的一些实施例中，所述步骤S240所述自一个或多个准供电电池包中确定供电电池包的步骤可以包括如下步骤：根据多个准供电电池包的供电性能自多个准供电电池包中确定供电电池包。例如，电池包A的理想使用寿命长于电池包B的理想使用寿命(以理想使用寿命为例，电池包的供电性能并非以此为限)，由此，当电池包A和电池包B都为准供电电池包时，选择电池包A作为供电电池包。In some embodiments of the present invention, the step S240 of determining the power supply battery pack from one or more quasi-power supply battery packs may include the following steps: according to the power supply performance of the multiple quasi-power supply battery packs The power supply battery pack is determined in the power supply battery pack. For example, the ideal service life of battery pack A is longer than the ideal service life of battery pack B (take the ideal service life as an example, the power supply performance of the battery pack is not limited to this), therefore, when both battery pack A and battery pack B are When quasi-power supply battery pack, select battery pack A as the power supply battery pack.
在本发明的各个实施例中，所述预定电量阈值可以是5％至20％。所述预定电量阈值与各电池包的充放电性能相关。In various embodiments of the present invention, the predetermined power threshold may be 5% to 20%. The predetermined power threshold is related to the charge and discharge performance of each battery pack.
