Description

Technical Field

[0001] This utility model relates to an on-board power management system, and more particularly to a power management system for a two-wheeled fuel vehicle. Background Technology

[0002] Two-wheeled gasoline vehicles (also known as gasoline motorcycles) are widely used as a convenient means of transportation. As an important component of two-wheeled gasoline vehicles, the battery is limited by the space of the motorcycle, making it difficult to increase the battery capacity by expanding its capacity (for current technology, increasing the battery capacity will lead to an increase in the size of the battery, and the installation space for the battery in a motorcycle is limited. An excessively large battery will affect the motorcycle's portability and will also lead to changes in the overall structure of the motorcycle, greatly increasing the cost). As a result, battery depletion is a frequent occurrence in two-wheeled gasoline vehicles.

[0003] In existing technologies, the testing of batteries in two-wheeled gasoline vehicles is generally conducted during driving. When a two-wheeled gasoline vehicle has not been used for a long time, the battery's charge capacity decreases due to self-discharge. At this time, it is difficult for users to detect that the battery is depleted or about to be depleted, thus affecting the subsequent use of the two-wheeled gasoline vehicle. On the other hand, because two-wheeled gasoline vehicles are equipped with high-power loads, even if a depletion occurs during driving, existing technologies cannot automatically disconnect the load based on the battery's state. Moreover, frequent depletion will also significantly reduce the battery's lifespan.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is urgent to propose a new technical approach. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Figure 1This is a schematic diagram of the structure of this utility model.

[0021] Figure 2 This is a schematic diagram of the first switch control circuit of this utility model.

[0022] Figure 3 This is a schematic diagram of the second switch control circuit of this utility model. Detailed Implementation

[0023] The present invention will be further described in detail below:

[0024] This utility model provides a power management system for a two-wheeled fuel vehicle, including: a voltage detection module, an on-board controller, a TBOX, an early warning module, and a remote early warning module;

[0025] The voltage detection module is used to detect the voltage of the two-wheeled fuel vehicle battery and output it to the vehicle controller and TBOX; wherein, the voltage detection module is a resistor voltage divider circuit, such as... Figure 2 As shown, it includes resistors R1, R3 and R2; one end of resistor R1 is connected to the positive terminal of the battery, and the other end is grounded through resistor R3; one end of resistor R2 is connected to the common connection point between resistors R1 and R2, and the other end is connected to the input terminal of the vehicle controller as an output terminal.

[0026] The vehicle controller is used to receive the battery voltage signal output by the voltage detection module and generate a warning command when the battery voltage is lower than the set value. The vehicle controller is existing technology. Generally, two-wheeled fuel vehicles (or fuel motorcycles or simply motorcycles) are equipped with corresponding vehicle controllers during production and can be used directly. It has corresponding signal acquisition and control functions.

[0027] The warning module is communicatively connected to the vehicle controller and is used to receive warning commands from the vehicle controller and issue warnings.

[0028] The vehicle controller is communicatively connected to the TBOX, which in turn is communicatively connected to the remote warning module. The TBOX is used by two-wheeled fuel vehicles to send warning commands to the remote warning module when the vehicle is stationary. TBOX is short for TelematicsBOX, a smart terminal device installed in a vehicle that integrates vehicle network and wireless communication functions. It connects various controllers within the vehicle via a CAN bus and utilizes 4G / 5G, GPS, and other modules to achieve vehicle-to-vehicle (V2V) and vehicle-to-cloud (V2N) communication. This is existing technology. In other words, in this application, when the vehicle is running, a warning module issues an alert for battery depletion (depletion is generally indicated by battery voltage; as the battery charge decreases, the voltage also decreases, and when the voltage drops to a certain level, depletion occurs), reminding the user to recharge the battery in time. When the vehicle is parked, the warning command is sent to a remote warning module via the TBOX, remotely prompting the user to recharge the battery. Thus, through this structure, the state of charge of the two-wheeled fuel vehicle's battery can be detected and real-time alerts can be issued whether the vehicle is running or parked, allowing for timely recharging to prevent battery depletion from affecting the user's vehicle use. Furthermore, it can automatically disconnect currently used loads when the battery is low, effectively preventing overuse of the battery and ensuring its lifespan.

[0029] In this embodiment, the warning module is a two-wheeled fuel vehicle instrument panel. As described above, there is no need to set up other warning devices, which can reduce the cost of use.

[0030] In this embodiment, the remote early warning module includes a monitoring server and a smart terminal held by the user of the two-wheeled fuel vehicle;

[0031] The monitoring server is connected to the TBOX, and the smart terminal is also connected to the monitoring server. The smart terminal uses an existing smartphone, which is associated with the user's smartphone after registration with the monitoring server. The monitoring server can be provided by the manufacturer or service provider of the two-wheeled fuel vehicle. This structure enables timely detection of low battery status of the two-wheeled fuel vehicle's battery when the vehicle is parked, timely charging warnings, prevention of battery depletion affecting the user's subsequent use, and ensuring the battery's lifespan.

[0032] In this embodiment, the vehicle controller and the TBOX, as well as the vehicle controller and the early warning module, are connected via a CAN bus. This CAN bus connection ensures efficient information transmission and facilitates expansion.

[0033] In this embodiment, a speed sensor is also included. The speed sensor is used to detect the engine speed of the two-wheeled fuel vehicle and output the engine speed signal to the vehicle controller. Through the function of the speed sensor, when the speed is 0 (indicating that the two-wheeled fuel vehicle is idle) and the speed is greater than 0 (indicating that the engine of the two-wheeled fuel vehicle is running, i.e., the two-wheeled fuel vehicle is running), the warning threshold voltage of the battery is adjusted, i.e., the set value mentioned above. For example, when the engine is running, the warning threshold voltage is 12.5V, and when the engine is not running, the warning threshold voltage is 11.5V. This is because when the engine is running, the voltage of the entire two-wheeled fuel vehicle system is generally greater than 12.5V, because the engine part is also generating electrical energy. Using 12.5V as the threshold voltage will reduce the risk of the battery running out of power. Because when the motorcycle is running, the user uses a lot of loads, such as heated handlebars, heated seat, external load sockets and audio equipment, etc. These loads generally have high power, so even when the motorcycle is running, the battery will run out of power.

[0034] When a two-wheeled gasoline vehicle is parked, the engine speed is 0. Generally, the vehicle controller is powered down, and the TBOX generates a warning command and sends it to the remote warning module. When the engine speed is not 0, the vehicle controller sends a command to the TBOX not to send a warning message. The vehicle controller then uses the instrument panel to issue a low battery warning.

[0035] In this embodiment, a first switch control circuit is also included. The first switch control circuit is used to control the on / off of the power supply circuit between the battery of the two-wheeled fuel vehicle and the lamps of the two-wheeled fuel vehicle. The first switch control circuit includes a Zener diode ZD1, a photoresistor LDR, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a resistor R8, a transistor T1, a transistor T2, a transistor T3, and a PMOS transistor Q1.

[0036] One end of the photoresistor LDR is connected to the positive terminal of the battery VBAT, and the other end of the photoresistor LDR is grounded through resistor R8. The common connection point between the photoresistor LDR and resistor R8 is connected to the base of transistor T1. The source of PMOS transistor Q1 is connected to the positive terminal of the battery VBAT. The drain of PMOS transistor Q1 serves as the output terminal of the first switching control circuit, supplying power to the lamp load. The source of PMOS transistor Q1 is connected to the gate of PMOS transistor Q1 through resistor R5. The gate of PMOS transistor Q1 is connected to the collector of transistor T3 through resistor R7. The output of transistor T3... With the emitter grounded, the base of transistor T3 is connected to the emitter of transistor T2 via switch SW1. The collector of transistor T2 is connected to the common connection point between resistor R5 and the gate of PMOS transistor Q1 via resistor R6. The base of transistor T2 is connected to the anode of Zener diode ZD1. The cathode of Zener diode ZD1 is connected to the common connection point between resistors R1 and R3. The emitter of transistor T1 is connected to the source of PMOS transistor Q1 via resistor R4. The collector of transistor T1 is connected to the base of transistor T2. Transistor T1 is a P-type transistor. Switch SW1... 1 is a push-button switch, the headlight switch for two-wheeled gasoline vehicles, usually located on the handlebars. When the user presses switch SW1, if the battery has sufficient charge, Zener diode ZD1 conducts, followed by transistor T2, which in turn conducts T3, and finally PMOS transistor Q1, powering the motorcycle's lights. If the battery voltage drops to near depletion, the voltage drop across R1 and R3 decreases, Zener diode ZD1 turns off, followed by transistors T2 and T3, and finally PMOS transistor Q1, thus disconnecting the lights. However, during motorcycle operation... When the ambient light is weak, forcibly disconnecting the power supply to the lights would pose a driving safety risk. Therefore, the photoresistor LDR is used to detect the ambient light of the motorcycle's current environment. When the ambient light is strong, the resistance of LDR is small, and the voltage drop across R8 is large. At this time, transistor T1 is cut off. When the ambient light is weak, the resistance of LDR increases, and the voltage drop across R8 decreases, causing T1 to be reverse biased and conduct. Consequently, transistors T2 and T3 conduct, and the PMOS transistor also remains on. Even if there is a power shortage, the lights are still powered. However, the vehicle controller will generate a power shortage command.

[0037] In this embodiment, a second switch control circuit is also included. The second switch control circuit is used to control the on / off of the power supply circuit between the battery of the two-wheeled fuel vehicle and the loads other than the lights of the two-wheeled fuel vehicle. The loads other than the lights include loads such as heated handlebars and heated seats.

[0038] The second switch control circuit includes resistors R9, R10, and R11, a Zener diode ZD2, a PMOS transistor Q2, a transistor T4, and a transistor T5. The source of PMOS transistor Q2 is connected to the positive terminal of the battery VBAT. The drain of PMOS transistor Q2 serves as the output terminal of the second switch control circuit, supplying power to the load. The source of PMOS transistor Q2 is connected to its gate through resistor R9. The gate of PMOS transistor Q2 is connected to the collector of transistor T5 through resistor R11. The emitter of transistor T5 is grounded. The base of transistor T5 is connected to the emitter of transistor T4 through switch SW2. The collector of transistor T4 is connected to the common connection point between resistor R9 and the gate of PMOS transistor Q2 through resistor R10. The base of transistor T4... The anode of Zener diode ZD2 is connected to the common connection point between resistors R1 and R3. Similar to the first switch control circuit, if the battery has sufficient power, when the user presses the button switch SW2, Zener diode ZD2 conducts. At this time, transistor T4 conducts, which in turn conducts, followed by transistor T5, and finally PMOS transistor Q2. The heated seat and heated grips of the motorcycle are powered. If the battery voltage drops to the point of near depletion, the voltage drop between R1 and R3 decreases, Zener diode ZD1 turns off, which in turn turns off transistors T2 and T3, and PMOS transistor Q1, thus disconnecting the battery power supply. Switch SW2 is an existing button switch, usually located on the handlebars of a motorcycle for easy operation.

[0039] In the above context, grounding refers to the zero potential point, i.e., the negative terminal of the battery.
