[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] A wireless transmission remote assistance battery management communication device, such as Figure 1 The system shown includes a main matching box and an optional matching box, wherein the main matching box is connected to the optional matching box via a serial port; the main matching box is connected to the battery module via a communication module, and the main matching box is used to verify, monitor, and forward communication data; the optional matching box is connected to the user terminal via wifi wireless, and the user terminal accesses the server via the Internet; the optional matching box is connected to the battery module via Bluetooth, and the battery module includes a Bluetooth communication unit, and the optional matching box is used to transmit communication data between the user terminal and the battery module.

[0030] like Figure 2 The main matching box includes an MCU and a communication module. The MCU adopts STM32. The communication module includes multiple protocol channels. For example, in this embodiment, it includes one RS485, three UARTs, one CAN, and one IIC channel. One UART is responsible for communicating with the matching box, and the other UART communicates with the computer through a USB to serial port chip. Data transmission has transparent transmission and monitoring functions.

[0031] The communication data between the user end and the battery module transmitted by the matching box includes the data request sent by the user end, the remote upgrade program package and the battery information responded by the battery module. The battery information includes one or more of the battery voltage, current and charge state. Figure 3In this embodiment, the optional box uses ESP32, which adopts a highly integrated Wi-Fi + Bluetooth solution. Only about 20 external components are needed, the circuit structure is simple, and the cost is low. ESP32 integrates antenna switch, RF Balun, power amplifier, low noise amplifier, filter and power management module, supports 802.11b / g / n, 802.11n (2.4GHz) speed up to 150Mbps, MCU is 32-bit LX6 single / dual-core processor, with computing power up to 600MIPS, including 3 UARTs, designed for mobile devices, wearable electronics and Internet of Things (IoT) applications, with ultra-high RF performance, stability, versatility and reliability.

[0032] The user end includes a mobile terminal (such as a mobile phone, etc.) or a computer user end. The battery module includes a Bluetooth communication function, and the optional box has a Bluetooth communication function and a WiFi communication function. The HC05 Bluetooth and ESP32 WiFi transmission technology are used to connect the battery and the optional box to the mobile phone or mobile end through wireless transmission. By intervening the user end in the server, the function of remote assistance is realized, so that the technician can intuitively see the user's battery usage problems through the remote computer, assist the user in solving the problem, send the upgrade package to the user end through remote operation, and the user end transmits the upgrade package to the optional box through WiFi, and upgrades the battery program through OTA.

[0033] A wireless transmission remote assistance battery management communication method comprises the following steps:

[0034] Step 1: The user end (computer client / mobile phone end) sends a data request (such as battery voltage, current, state of charge and other battery information) to the optional box via wireless;

[0035] Step 2: The optional matching box sends the data request to the main matching box through the serial port;

[0036] Step 3: The main distribution box MCU determines whether the data request meets the protocol requirements through a custom protocol. If it meets the protocol requirements, it executes step 4 to forward it; if it does not meet the requirements, it discards the data;

[0037] Step 4: The main distribution box selects a matching protocol channel according to the battery module, including RS485, UART2, CAN, and IIC channels, and forwards the data request parsed by the MCU to the battery module. The battery module responds after receiving the request.

[0038] Step 5: The main distribution box receives the data responded by the battery module and determines whether the responded data meets the protocol requirements. If so, step 6 is executed; if not, the data is discarded.

[0039] Step 6: The main matching box analyzes the data and forwards the analyzed data to the optional box through the serial port; in addition, the main matching box can also upload the data to the computer through the USB to serial port, supporting offline transmission of battery information.

[0040] Step 7: The optional box sends the received data to the user end via WiFi / Bluetooth;

[0041] Step 8: The user end analyzes the response data and intuitively displays the battery information. The user end uploads the data to the server for the technician to view. The technician remotely assists the user in viewing the battery status through a computer remotely accessing the server. When a battery failure occurs, the user accesses the server through a communication device, and the technician can view the corresponding failure and assist in solving it.

[0042] Step 9: The user receives the remote upgrade program package, sends the remote upgrade program package to the optional box, and upgrades the battery module program through OTA to solve the battery failure.

[0043] This method is not only convenient for users to operate, but also for R&D personnel to operate. They can change and upgrade programs remotely without having to go to the site. In addition, wireless transmission is used to save wires, save wiring space, and reduce complicated manual operation steps.
