Description

Technical Field

[0001] The present invention relates to the technical field of power supply control devices, and in particular to a power supply control device for an electric two-wheeled vehicle. Background Art

[0002] Currently, electric two-wheeled vehicles lack power safety control measures. Since electric two-wheeled vehicles are equipped with many on-board electrical appliances, the parking and starting time of a new battery is shortened to about five days. Therefore, for electric two-wheeled vehicles that are not used frequently, they need to be connected to the ignition and started.

[0003] In the prior art, electric two-wheeled vehicles do not have a battery-powered power control device for parking. First, when the electric two-wheeled vehicle is parked, the mechanical lock only cuts off the main circuit, while some circuits still consume power invisibly. Long-term idleness can cause the battery to run out and become unable to start. Users need to frequently charge or replace the battery, which increases the cost of use.

[0004] Secondly, if the line is aging, damp, or short-circuited, without a power isolation device, the high-voltage battery will continue to leak electricity through the faulty circuit, causing overheating and fire risks. The fault is difficult to detect in time, posing a safety hazard.

[0005] Finally, if electronic components such as controllers and instruments are in standby mode for a long time, their performance will be degraded due to voltage fluctuations or static electricity accumulation, further reducing the reliability of the vehicle and increasing the frequency of maintenance.

[0006] Therefore, a power supply control device for an electric two-wheeled vehicle is provided to solve the above-mentioned problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a power supply control device for an electric two-wheeled vehicle, so as to avoid the problems of the electric two-wheeled vehicle failing to start due to power loss and abnormal hidden leakage, and to achieve safe management of the power supply of the electric two-wheeled vehicle.

[0025] Example

[0026] like Figure 1As shown, the present invention provides a power control device for an electric two-wheeled vehicle, including a control unit and a lighting unit connected to the control unit, a voltage input unit, a DCDC isolator 1, a drive unit, a protection unit and a switch assembly 2. The control unit includes a central control box 3 and a CAN communication box 4. Data is transmitted between the central control box 3 and the CAN communication box 4 via a shielded twisted pair cable 25 to achieve centralized management and real-time monitoring of the power supply, ensure coordinated operation of each unit, and reduce abnormal power consumption. The voltage input unit, the DCDC isolator 1 and the drive unit are all connected to the central control box 3 via a rigid cable 24.

[0027] The central control box 3, as the control end of the power supply, is also responsible for controlling the vehicle key signal, including Bluetooth key, wireless key and mechanical key, to realize the starting function of the electric two-wheeled vehicle. When the key signal is activated, the DCDC isolator 1 is controlled to power other units. When the electric two-wheeled vehicle is locked, the central control box 3 is in a dormant state, the entire vehicle is powered off, and the power consumption is the dormant current; when the inactivity time exceeds the time threshold, the central control box 3 is also powered off. The only way to start again is to power the central control box 3 by starting the mechanical key.

[0028] The voltage input unit includes a power battery 5 and a mechanical lock 6. The output voltage of the power battery 5 is set to 96V. The power battery 5 is connected to the central control box 3 via a rigid cable 24. The power battery 5 is connected to the mechanical lock 6 via a rigid cable 24. The mechanical lock 6 is connected to the central control box 3 via a rigid cable 24. The mechanical lock 6 acts as a physical switch to completely cut off the power supply to prevent hidden leakage when the electric two-wheeled vehicle is idle.

[0029] When the voltage of the power battery 5 drops to the starting critical point range, the central control box 3 controls the device to enter the low power consumption mode, cuts off the power supply of the DCDC isolator 1, and sends a fault signal at the same time;

[0030] When the voltage of the power battery 5 is higher than the voltage threshold and a continuous or periodic high current discharge is detected, the central control box 3 automatically cuts off the power supply of the DCDC isolator 1 .

[0031] The drive unit includes a motor 7 and a controller 8. The controller 8 is connected to the motor 7 through a rigid cable 24. Data is transmitted between the controller 8 and the CAN communication box 4 through a shielded twisted pair 25. The controller 8 is connected to the central control box 3 through a rigid cable 24. A rigid cable reserved line 26 is provided between the controller 8 and the central control box 3 to ensure that the power supply to the motor can be quickly cut off in an emergency to avoid continuous power consumption due to controller failure.

[0032] The output voltage of the DCDC isolator 1 is set to 12.9V. A direction lock 9 is provided between the DCDC isolator 1 and the CAN communication box 4. The CAN communication box 4 is connected to the direction lock 9 via a rigid cable 24. The direction lock 9 is connected to the CAN communication box 4 via a rigid cable 24. The DCDC isolator 1 is connected to the CAN communication box 4 via a rigid cable 24.

[0033] The DCDC isolator 1 isolates the high voltage system from the low voltage system to prevent leakage caused by voltage fluctuation or short circuit, and further controls the circuit on and off through the direction lock 9.

[0034] The lighting unit includes a left front turn signal lamp 10, a right front turn signal lamp 11, a left rear turn signal lamp 12, a right rear turn signal lamp 13, a high beam lamp 14, a low beam lamp 15, a position lamp 16, a tail light 17, and a license plate lamp 18. The left front turn signal lamp 10, the right front turn signal lamp 11, the high beam lamp 14, the low beam lamp 15, and the position lamp 16 are all connected to the CAN communication box 4 via a rigid cable 24. The left rear turn signal lamp 12, the right rear turn signal lamp 13, the tail light 17, and the license plate lamp 18 are all connected to the central control box 3 via a rigid cable 24.

[0035] The front turn signals and rear turn signals are managed by the central control box 3 and the CAN communication box 4 respectively, distributing the load and controlling them independently to prevent a single circuit from overloading or short-circuiting and causing leakage of the entire vehicle.

[0036] The protection unit includes a TFT instrument 19, a gyroscope 20, a bucket lock 21, and a speaker 22. A T-BOX 23 is provided at the bottom of the TFT instrument 19. The TFT instrument 19 and the gyroscope 20 both transmit data to the CAN communication box 4 via a shielded twisted pair 25. The bucket lock 21 is connected to the central control box 3 via a rigid cable 24. The speaker 22 is also connected to the CAN communication box 4 via a rigid cable 24.

[0037] The gyroscope 20 monitors the running state of the electric two-wheeled vehicle in real time, obtaining data such as the vehicle's speed, acceleration, and tilt angle. When it detects that the electric two-wheeled vehicle's motion state is unstable, it sends a signal to the central control box 3 via the CAN communication box 4, automatically cutting off the power supply to the motor 7 to prevent loss of control or battery over-discharge.

[0038] The TFT instrument 19 can receive and process data from other units to ensure synchronous information update, and display key data such as the speed, acceleration, battery power, mileage, status of the light unit, fault alarm, etc. of the electric two-wheeled vehicle in real time, providing an intuitive human-computer interaction interface, improving the driving experience, and helping users to grasp the status of the electric two-wheeled vehicle in a timely manner to avoid accidents due to insufficient power or system failure.

[0039] T-BOX23 can synchronously upload the operating data of electric two-wheeled vehicles to the cloud, allowing users to remotely control the vehicle through the user-side APP.

[0040] The switch assembly 2 includes a left-hand switch assembly 201 and a right-hand switch assembly 202. Both the left-hand switch assembly 201 and the right-hand switch assembly 202 transmit data to the CAN communication box 4 through a shielded twisted pair cable 25, which can reduce signal interference and avoid power supply abnormalities caused by misoperation or signal loss.

[0041] Therefore, the present invention adopts the above-mentioned power supply control device of the electric two-wheeled vehicle, centrally manages the power supply through the central control box, monitors the status of the electric two-wheeled vehicle in real time through the protection unit, and simultaneously performs hardware isolation and branch control design, which effectively solves the problems of power shortage and hidden leakage, and improves the safety and reliability of the power supply system.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the method scheme of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary method personnel in this field should understand that they can still modify or replace the method scheme of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified method scheme to deviate from the spirit and scope of the method scheme of the present invention.
