[0018] Port 0, port 1 and port 6 of the first connector J1 are respectively connected to the charge and discharge protection control board; port 2, port 3, port 4 and port 5 of the first connector J1 are respectively connected to the charge and discharge management control board; port 0 of the first connector J1 is connected to one end of the first resistor L1, and the other end of the first resistor L1 is respectively connected to one end of the first capacitor C1 and the power signal port of the charge and discharge protection control board, and the other end of the first capacitor C1 is grounded; port 1 of the first connector J1 is connected to one end of the second resistor R1, and the other end of the second resistor R1 is connected to the current acquisition signal port of the charge and discharge protection control board; port 2 of the first connector J1 is connected to the anode of the first diode D1, and the cathode of the first diode D1 is connected to the overcurrent, overvoltage, Over-discharge protection signal port; Port 3 of the first connector J1 is connected to the anode of the second diode D2, and the cathode of the second diode D2 is connected to the charge and discharge MOS control signal port of the charge and discharge management control board; Port 4 of the first connector J1 is connected to one end of the third resistor L2, and the other end of the third resistor L2 is connected to the battery voltage transmission signal port of the charge and discharge management control board; Port 5 of the first connector J1 is connected to one end of the fourth resistor R3, and the other end of the fourth resistor R3 is connected to the fuse control signal port of the charge and discharge management control board; Port 6 of the first connector J1 is connected to the cathode of the third diode D3, and the anode of the third diode D3 is respectively connected to one end of the fifth resistor R2 and the power control signal port of the charge and discharge protection control board, and the other end of the fifth resistor R2 is connected to the VCC power supply.

[0019] like Figure 5As shown, there are at least two second connectors J2, and the model of the second connector J2 is A2912WVA-F-13P.

[0020] Port 0 of the second connector J2 is connected to the sampling port of the battery; ports 1 to 8 of the second connector J2 are respectively connected to the sampling signal ports of the charge and discharge management control board; and resistors are respectively connected between ports 1 to 8 of the second connector J2 and the sampling signal ports of the charge and discharge management control board.

[0021] The integrated adapter board used in the utility model is provided with a plurality of interfaces (management and control interfaces) connected with the charge and discharge management control board, namely the first connector J1, the first connector J1 uses 1-1871315-326pos; and an interface (sampling interface) connected with the battery pack cell, namely the second connector J2, the second connector J2 uses A2912WVA-F-13P.

[0022] like Figure 4 As shown, diodes (i.e., the first diode D1, the second diode D2, and the third diode D3) are used on the first connector J1 to isolate the signals of each interface, and anti-mutual charging and anti-irrigation functions are set between each pin to protect the chip pins. For example, the charging and discharging MOS pins are integrated into the first connector J1.

Multiple charge and discharge management boards and cards exchange information in real time through the communication unit to collaboratively complete the charge and discharge tasks. Each board and card makes a comprehensive judgment based on its own monitoring data, and controls the corresponding charge and discharge control unit to operate. Through the collaborative work between the boards and cards, the uniform charge and discharge of the battery pack can be achieved, avoiding the occurrence of problems such as overcharging and over-discharging.

[0024] The utility model has the following innovative features:

[0025] 1. Compared with the traditional single management control board, this centralized switching method can reduce the impact of faults on the entire battery pack and improve system reliability and stability.

[0026] 2. The high-precision sensors on each charge and discharge management control board can monitor the key parameters of the battery unit in real time, such as voltage, current, and temperature, and transmit the key parameters through the hub adapter interface. Once a management control board detects an abnormal situation, it will start controlling the charge and discharge protection control board and cut off the charge and discharge circuit, so as to protect the battery pack more effectively.

[0027] 3. The integrated adapter board provides a standardized universal interface to facilitate the connection of each management control board. At the same time, the management control boards can share data and work together through the adapter board to achieve efficient, safe and accurate management of the entire battery pack. This data sharing and collaborative working method can further improve the management efficiency and accuracy of the system.

[0028] 4. The adapter board adopts a plug-and-play design, so that the new charge and discharge management control board can be powered on and started without complicated configuration and debugging. This design can greatly improve the scalability and ease of use of the system.
