[0024] Specifically, in the embodiment, the password processing module and the storage module are arranged in the MCU.
[0025] The password processing module serves as the core control unit of the system, and is responsible for receiving the signal transmitted by the password input module and verifying and processing the password.
[0026] In the embodiment, the model of the MCU is GD32E230C8T6, which is a microcontroller (MCU) based on the ARM Cortex-M23 core produced by STMicroelectronics, and belongs to the GD32 series products, and has fast data processing capability and stable running performance. The MCU has a built-in encryption algorithm, which can encrypt the user input password, improve the security of the password, and prevent the password from being easily cracked. The password processing is performed by the MCU to encrypt the user input password by methods such as md5 and store it in EEPROM or Flash.
[0027] Specifically, in the embodiment, the power module uses a DCDC chip to perform voltage stabilization and filtering processing on the battery of the electric vehicle. The power module has a low-power management function, and is connected with a rotary knob switch.
[0028] The power module uses a DCDC chip to convert the battery voltage of the electric vehicle into the working voltage required by the system, and performs voltage stabilization, filtering and other processing on the battery of the electric vehicle to ensure that the system works normally under different voltage fluctuations. The DCDC chip is used for voltage conversion to convert the external 48v / 60v / 72v voltage into the required 3.3v voltage. The power module has a low-power management function, and automatically enters a low-power mode when the electric vehicle is parked for a long time to reduce the consumption of battery power.
[0029] Low power mode: through the MCU to realize the low power consumption of the power module, the process is that the MCU enters the low power mode, turns off the functions of peripherals such as screen, keyboard, WIFI / BLE communication, and reduces the working power consumption; then it is awakened through the power level.
[0030] Specifically, in the embodiment, the storage module adopts a non-volatile memory and has a certain capacity.
[0031] The storage module selects a non-volatile memory (such as EEPROM or Flash memory) to ensure that data will not be lost after the electric vehicle is powered off. The storage module has a certain capacity to support user password modification and multiple password storage. The storage module uses the EEPROM or Flash of the MCU itself, which can store 5-10 passwords for vehicle unlocking.
[0032] Specifically, in the embodiment, the display module is a liquid crystal display screen or a light-emitting diode display screen.
[0033] The display module is a liquid crystal display screen (LCD) or a light-emitting diode display screen (OLED), which is used to display the working state of the system, password input prompt information, and error prompt, etc. The display screen has good visual angle and brightness, so that users can clearly see the display content under different light conditions. Information can be conveyed to users intuitively through icons, text, etc., improving the usability of the system.
[0034] Specifically, in the embodiment, the password input module is a keyboard, which has waterproof and dustproof functions, and each key on the keyboard has clear identification and good tactile feedback.
[0035] The password input module includes a touch keyboard or a physical button keyboard, which is installed near the electric vehicle instrument panel or handlebar for easy user operation. It is designed to be waterproof and dustproof to adapt to various outdoor environments, and each key has clear identification and good tactile feedback to ensure accurate user input.

[0037] The communication module is used to realize the communication function between the password boot system and the remote device (such as mobile phone APP or vehicle management system). The communication module adopts Bluetooth, Wi-Fi or other wireless communication technology, which is convenient for users to set passwords, query vehicle status and other operations through mobile phones and other devices. The communication module has good communication stability and security to prevent data from being disturbed or stolen during transmission.
[0038] The password starting system has high security, is convenient to use, has strong expansibility and good economic benefits. The electric vehicle is started through the password verification mode, and compared with the traditional key starting mode, the difficulty of vehicle theft is greatly increased. The password encryption storage and the multiple password error locking security mechanism further guarantee the safety of the vehicle. The user only needs to remember the preset password, and the vehicle can be easily started, without carrying the traditional key, and the inconvenience caused by losing or forgetting the key is avoided. The password setting and modification process is simple and easy to understand, and the user can operate at any time according to the own needs.
[0039] The password starting system reserves a communication module interface, which is convenient for subsequent integration with a mobile phone APP or other vehicle management systems to realize more function extensions, such as remote password control, vehicle state query, theft prevention tracking and the like, and improve the use experience of the user and the intelligent management level of the vehicle.
[0040] The password starting system is relatively reasonable in hardware cost, and can replace the traditional key starting system to a certain extent, reduce the cost of key manufacturing and management. At the same time, since the security of the vehicle is improved and the risk of vehicle theft is reduced, in the long run, the user and the manufacturer also bring economic benefits.
[0041] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
