[0045] Handlebar combination switch module 2: used to turn on or off the long-endurance mode;

[0046] Signal acquisition module 3: used for collecting the on signal or off signal of the throttle combination switch module 2, and sending the on signal or off signal to the main control module 4;

[0047] Main control module 4: used to receive the start signal or the close signal of the signal acquisition module 3;

[0048] According to the start signal, the sodium battery module 1 is controlled to enter a low voltage mode through the SOC one-line communication protocol;

[0049] According to the shutdown signal, the sodium battery module 1 is controlled to enter a normal voltage mode through the SOC one-line communication protocol;

[0050] It can be understood that the sodium battery module 1 provides power for the electric two-wheeled vehicle electrical equipment, using 24 sodium battery cells connected in parallel as a whole pack of batteries (single cell is 1.8-3.95V), with a nominal voltage of 72V, a rated capacity of 24Ah, and an operating voltage of 44-95V;

[0051] The circuit principle of the main control module 4 is shown in the attached Figure 5 As shown, the main control module 4 in this application is mainly based on the signal acquisition module 3 (the circuit principle of the signal sampling module 3 is shown in the attached Figure 3The on signal or off signal of the throttle combination switch module 2 collected by the SOC one-line communication protocol is used to control the output voltage mode of the sodium battery module 1, wherein the voltage output module of the sodium battery module 1 includes two types, one is a normal voltage mode, that is, the output voltage of the sodium battery module 1 is 55V-95V, and the second is a low voltage module, that is, the output voltage of the sodium battery module 1 is 45V-55V. When the output voltage of the sodium battery module 1 is in the low voltage mode, the system enters the long endurance mode;

[0052] As attached Figure 2 As shown, the present application also includes a voltage acquisition module 5 (the circuit principle of the voltage sampling module 5 is shown in the attached Figure 4 As shown), the voltage acquisition module 5 is used to collect the output voltage of the sodium battery module 1, and determine whether the output voltage of the sodium battery module 1 reaches a critical value through the main control module 4. When the critical value is reached, it is displayed through the instrument module 8 to remind the user;

[0053] Intelligent central control module 6 (Bluetooth / GPS): establishes a link with the mobile phone intelligent terminal 7 to realize Bluetooth and remote control of the vehicle working status. After the mobile phone intelligent terminal 7 is successfully connected to the intelligent central control module 6, the user can view and change the function switch status of the main control module 4, and can also turn on the long-endurance switch (i.e., turn on the second stage of low voltage) on the mobile phone intelligent terminal 7, change the working mode of the sodium battery module 1 (low voltage mode), and achieve a longer endurance capability;
