BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings and examples;

[0021] Figure 1 A system architecture diagram of a preferred embodiment of the present invention; DETAILED DESCRIPTION

[0022] The following drawings illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0023] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0024] This embodiment provides a battery charge and discharge management system. The circuit of the battery charge and discharge management system has the characteristics of integrated modularization and fewer circuit connection lines, which reduces the circuit failure rate. The circuit has clear functional divisions, its charge and discharge strategy is nonlinear, the charge and discharge strategy is provided quickly, and it is suitable for a wide range of scenarios. In addition, the normal installation status pre-inspection of the charging and discharging peripherals is adopted to avoid loose connections between the charging and discharging interface and its peripherals, thereby improving the safety of the equipment and circuits. At the same time, the battery charge and discharge management system of the present invention adopts a modular design, which can facilitate the replacement and maintenance of modules.

[0025] like Figure 1As shown, the battery charge and discharge management system of this embodiment includes a battery module, a filter module, an analog front-end integrated circuit module, and an MCU module. There is at least one battery module to perform system charging and discharging. The filter module uses circuits to filter input or output. The analog front-end integrated circuit module collects and converts signals for output. The MCU module processes the signals collected by the analog front-end integrated circuit module and performs feedback processing. It also receives electrical signals indicating the access status of peripheral devices on the charging and discharging sides of the system for logical judgment. When the charger is connected to the charging dock, a low-level signal is fed back to the MCU module. After receiving this low-level signal, the MCU module updates its peripheral status and waits for the next scenario action. When the external controller is connected to the discharge dock, its peripheral status is updated in the same way. The signal acquisition, conversion and output module sends the collected signal to the MCU module. The MCU module processes and judges the signal and then performs the scenario action of switching the MOSFET on the charging or discharging side to the corresponding charging channel to achieve the switching of the charge and discharge modes. The electrical energy on the charging side is then sent to the battery charging and discharging part, thereby performing the charging operation. The battery charge and discharge power is then transmitted via a transmission line to the input filter, where it is filtered and sent to the analog front-end integrated circuit module. This module then performs a judgment operation, causing the positive and negative switching MOS transistors of the corresponding channels to perform the corresponding scenario-specific actions. The battery energy is then transmitted via a transmission line to the discharge socket, where the peripheral device discharges.

[0026] In this embodiment, a charging MOS tube is provided on the charging side of the system to perform a charging action after a switch judgment, and a discharging MOS tube is provided on the discharging side of the system to perform a discharging action after a switch judgment.

[0027] The battery charge and discharge management system of this embodiment further includes a CAN bus, which is connected to the external controller for communication. After the MCU module receives a low-level signal, it updates the status of the charging peripherals and the discharging peripherals.
