Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.
[0050] like Figure 1 As shown, a vehicle power supply control method according to the present invention is provided, wherein the vehicle power supply module comprises: a parallel structure of a battery pack and a supercapacitor; wherein the battery pack may be a stacked lithium battery pack.
[0051] The method comprises:
[0052] Step 11: Obtain the running status of the vehicle. In the present invention, the vehicle may be a rail-guided vehicle (RGV) or other vehicles.
[0053] Step 12: Control the power supply mode of the battery pack and the supercapacitor according to the operating state.
[0054] In this invention, the vehicle's power supply module includes a parallel structure of a battery pack and a supercapacitor. The power supply mode of the battery pack and supercapacitor is controlled according to the vehicle's operating state. Therefore, the invention adopts a contactless power supply, avoids physical wear, can operate stably in dusty and humid environments, and has high reliability.
[0055] In the present invention, the vehicle's operating state can be the vehicle's real-time operating state, or the vehicle's predetermined operating state can be predicted based on the vehicle's predetermined trajectory, so that the power supply mode of the battery pack and the supercapacitor can be controlled based on the vehicle's predetermined operating state. Each of these is described in the following embodiments.
[0056] In one embodiment, step 12 includes:
[0057] In step 121, when the vehicle's real-time power demand is greater than a predetermined power threshold, the branch circuit between the supercapacitor and the vehicle is opened, and the branch circuit between the battery pack and the vehicle is maintained or disconnected. In other words, in this embodiment, the vehicle can be powered by both the supercapacitor and the lithium battery simultaneously, or by the supercapacitor alone, depending on the actual situation.
[0058] The acquiring of the vehicle being in an instantaneous high power demand state includes:
[0059] A vehicle acceleration request is received; or
[0060] A vehicle start request is received; or
[0061] A vehicle stop request is received; or
[0062] The vehicle is detected to be on an uphill slope; or
[0063] Or it is detected that the vehicle is turning.
[0064] In the above embodiment, control is performed according to the real-time operating status of the vehicle, and a stacked lithium battery pack and a supercapacitor are connected in parallel. After parallel connection, the two complement each other, the lithium battery provides continuous power, and the supercapacitor can respond to instantaneous high power demands.
[0065] In another embodiment, step 12 includes:
[0066] Step 122 : When it is determined that the vehicle is in a braking energy recovery state and the peak current of the vehicle is greater than a predetermined threshold, the branch between the supercapacitor and the vehicle is opened, and the branch between the battery pack and the vehicle is maintained or disconnected.
[0067] In the above embodiment, the supercapacitor bears the peak current, reduces the number of charge and discharge cycles of the lithium battery (such as the capacitor absorbing current pulses during braking energy recovery), and alleviates problems such as SEI film (solid electrolyte interface film) thickening and lithium dendrite growth caused by high-rate operating conditions of lithium batteries.
[0068] Step 122 is specifically as follows:
[0069] Step 1221: When it is determined that the vehicle is in a braking energy recovery state and the peak current of the vehicle is greater than a predetermined threshold, the braking energy of the vehicle is first absorbed by the supercapacitor;
[0070] Step 1222: When the energy storage rate of the supercapacitor is greater than a predetermined energy storage rate threshold, the braking energy of the vehicle is slowly charged to the battery pack through a current limiting circuit.
[0071] The step of obtaining the braking energy recovery state of the vehicle includes:
[0072] A vehicle deceleration request is received; or
[0073] The vehicle is detected to be traveling downhill.
[0074] In another embodiment, the vehicle is provided with a wireless charging receiving terminal;
[0075] A wireless charging transmitter is provided at a predetermined position on the vehicle track;
[0076] The control method further includes:
[0077] In step 13, when the vehicle is detected at the predetermined location, the wireless charging transmitter is activated to power the vehicle's battery pack and / or supercapacitor via the wireless charging receiver. The present invention can charge both the battery pack and supercapacitor simultaneously, or only the battery pack. This is not a limitation of the present invention and can be configured based on actual circumstances.
[0078] In this invention, wireless charging coils are installed in sections of the track, triggering intermittent charging when a device passes by, extending battery life. The predetermined locations can be vehicle stops and / or predetermined sections of the vehicle's trajectory. The transmitting coil can utilize a segmented Litz wire design.
[0079] In the above embodiment, it is possible to
[0080] The specific steps of starting the wireless charging transmitter are:
[0081] Monitor whether there is a living body in a predetermined area centered at the predetermined position; specifically, the monitoring can be performed through a living body detection module, which can include an infrared sensor and / or a millimeter wave radar.
[0082] If the judgment result is no, the wireless charging transmitter is started.
[0083] This embodiment ensures safety by performing liveness detection.
[0084] Additionally, the trigger mechanism can be based on RFID position verification and current fingerprint recognition, preventing false triggering and enabling charging in less than 0.1s. As the RGV moves along the track, the RFID tag provides location information, and the control center issues charging instructions to the corresponding track section. Upon entering the charging zone, the wireless charging module initiates energy replenishment, while the supercapacitor absorbs transient power.
[0085] In another embodiment, step 12 includes:
[0086] When the battery state of charge (SOC) is less than a charge threshold and the real-time power demand is greater than a power threshold, a strategy of using wireless charging and / or supercapacitor power supply is enabled.
[0087] In another embodiment, step 12 includes:
[0088] Step 123, obtaining terrain data of the vehicle's path to be operated;
[0089] Step 124, obtaining predetermined operating states of the vehicle on different sections of the route to be operated based on the terrain data;
[0090] Step 125 : Controlling the power supply mode of the battery pack and the supercapacitor according to the predetermined operating state.
[0091] In the present invention, the real-time track topology data (such as ramp / curve coordinates) is integrated through an algorithm to preload the energy supply strategies for different road sections.
[0092] Step 125 includes:
[0093] Step 1251, when the vehicle is traveling at a constant speed, the battery pack is used for power supply;
[0094] Step 1252: before the vehicle reaches an uphill section or a turning section for a first predetermined time, output auxiliary power through the supercapacitor; or
[0095] Step 1253: Before the vehicle reaches the downhill section for a second predetermined time, discharge the capacitor so that the capacitor maintains the reserved capacitance, and when the vehicle reaches the downhill section, connect the branch between the supercapacitor and the vehicle so that the supercapacitor recovers braking energy.
[0096] In the above embodiment, real-time track topology data (such as ramp / curve coordinates) can be integrated through algorithms to preload energy supply strategies for different road sections and improve the environmental adaptability of RGV.
[0097] Furthermore, the energy supply strategy for different road sections can be predetermined by combining the predicted vehicle speed with the real-time track topology data, thus improving the accuracy of the RGV’s environmental adaptation.
[0098] The method also includes monitoring device status in real time using vibration sensors, temperature sensors, and other sensors, triggering shutdown protection and reporting any anomalies. Specifically, the vibration sensor can detect whether charging between the wireless charging receiver and transmitter is normal. The temperature sensor can detect whether the temperature of the vehicle's supercapacitors, lithium batteries, and other components is normal. The humidity sensor can detect whether the vehicle's environment is normal. This allows for real-time monitoring of the vehicle's operating status.
[0099] The present invention can be applied to rail-guided vehicles (RGVs) and their power supply systems that use non-trolley busbar power supply methods, and is suitable for material handling scenarios such as smart manufacturing plants and warehousing and logistics centers.
[0100] The technical solution of the present invention is described below.
[0101] The present invention comprises:
[0102] 1. Hybrid energy power supply system:
[0103] 1. Energy storage unit:
[0104] The energy storage unit adopts a parallel structure of stacked lithium battery pack and supercapacitor. After parallel connection, the two complement each other. The lithium battery provides continuous power, and the supercapacitor responds to instantaneous high power demand (such as acceleration, start and stop); the supercapacitor bears the peak current, reducing the number of charge and discharge cycles of the lithium battery (such as the capacitor absorbs current pulses during braking energy recovery), and alleviating the problems of SEI film thickening and lithium dendrite growth caused by high-rate operating conditions of lithium batteries.
[0105] 2. Wireless charging module:
[0106] A magnetic resonance wireless charging transmitter is installed at the RGV stop or on a specific road section, and the on-board receiver realizes contactless power transmission through high-frequency resonance.
[0107] The transmitting coil adopts a segmented Litz wire design to reduce proximity effect loss (15% efficiency improvement compared to traditional coils).
[0108] 3. Liveness detection module: It uses infrared sensors and millimeter-wave radars to monitor and prevent activation when foreign objects enter the charging area.
[0109] 2. Dynamic Energy Management Algorithm
[0110] Core algorithm:
[0111] # Pseudocode Example: Dynamic Policy Selector
[0112] def energy_strategy_selector():
[0113] if SOC_batt<20% and power_demand>10kW:
[0114] Enable wireless charging + capacitor power supply#power conservation mode
[0115] elif regen_energy>5kJ:
[0116] Supercapacitor priority recovery + triggering secondary battery slow charging #Braking optimization
[0117] else:
[0118] Load balancing mode based on path slope prediction ------------------------------------------------------------------------------------
[0119] The following is a technical explanation:
[0120] Condition 1: When the lithium battery state of charge (SOC) is less than 20% and the real-time power demand is greater than 10kW, wireless charging and capacitor power supply are enabled. The execution strategy is: power conservation mode.
[0121] Technical logic:
[0122] When the lithium battery is low in power, high-rate discharge will accelerate aging. Under this condition:
[0123] 1. Force activation of the track wireless charging module (external power supply)
[0124] 2. Supercapacitor provides instantaneous high power (to protect lithium batteries)
[0125] Double protection to avoid system downtime;
[0126] Condition 2: When regenerative braking energy > 5kJ is detected (e.g., vehicle deceleration / downhill), the supercapacitor prioritizes recovery and triggers slow charging of the secondary battery. The execution strategy is: Braking Optimization.
[0127] Technical logic:
[0128] High pulse energy (>5kJ) generated by regenerative braking is preferentially absorbed by supercapacitors (fast response, pulse resistance)
[0129] When the capacitor is nearly fully charged, the remaining energy is slowly charged to the lithium battery through the current limiting circuit (to avoid high current shock of lithium battery)
[0130] Therefore, the problem of braking energy waste in traditional solutions is solved.
[0131] Other common working conditions: load balancing mode based on path slope prediction. Execution strategy: intelligent load distribution.
[0132] The technical logic is:
[0133] 1. Preload track terrain data (such as slope changes ahead)
[0134] 2. Dynamically allocate energy:
[0135] Uphill section: Supercapacitor outputs auxiliary power in advance
[0136] Downhill section: Reserve capacitor capacity to recover braking energy
[0137] It is also possible to use algorithms to fuse real-time track topology data (such as ramp / curve coordinates) and preload energy supply strategies for different road sections.
[0138] 2. Modular track design:
[0139] Wireless charging coils are configured in sections of the track, triggering intermittent charging when the device passes by, extending battery life;
[0140] Trigger mechanism: RFID-based position verification + current fingerprint recognition. This prevents false triggering and allows charging to start in less than 0.1s.
[0141] 3. Safety and monitoring system:
[0142] Multi-level insulation protection: an electromagnetic shielding layer and an insulation isolation structure are set between the energy storage unit and the vehicle body;
[0143] Health Diagnosis Module: Vibration and temperature sensors monitor device status in real time, triggering shutdown protection when abnormalities occur and uploading the information to the cloud-based operations and maintenance platform. Specifically, the vibration sensor detects whether charging between the wireless charging receiver and transmitter is normal. The temperature sensor checks the temperature of the vehicle's supercapacitors, lithium batteries, and other components. The humidity sensor checks whether the vehicle's environment is normal.
[0144] Correspondingly, the RGV power supply system structure includes:
[0145] On-board unit: lithium battery pack (48V / 100Ah), supercapacitor module (16F), wireless receiving coil, energy management controller (MCU);
[0146] Track unit: segmented wireless charging transmitter (frequency 85kHz, power 3kW), radio frequency identification (RFID) tag;
[0147] Control center: A scheduling system based on 5G communication, integrating energy management algorithms and path planning engines.
[0148] When the RGV runs along the track, the RFID tag provides location information, and the control center sends charging instructions to the corresponding track section;
[0149] After entering the charging area, the wireless charging module starts to replenish energy, while the supercapacitor absorbs transient power;
[0150] The energy management controller switches the energy supply mode according to the operating status: the lithium battery is used for power supply during constant speed driving, and the supercapacitor assists the output during acceleration / climbing;
[0151] When the vehicle stops, braking energy recovery is triggered, converting kinetic energy into electrical energy and storing it in the supercapacitor.
[0152] When the battery SOC (State of Charge) is lower than 20%, the control center will prioritize dispatching the RGV to the charging area to complete rapid energy replenishment.
[0153] During low-load periods (such as at night), the system automatically switches to low-power mode and only maintains basic communication functions;
[0154] By predicting equipment energy consumption trends through deep learning, charging cycles and route planning can be optimized.
[0155] like Figure 2 As shown in the figure, the overall process of RGV power supply system operation includes:
[0156] First, start with system startup.
[0157] Next, the self-test program confirms whether the power supply system is normal, such as the power supply system, sensors, communication modules, etc.
[0158] If there is an abnormality, an alarm will be generated, the machine will be shut down, and then manual maintenance will be carried out;
[0159] If it is normal, initialize the power supply status and read the battery power and capacitor power.
[0160] Then it enters standby mode (low power consumption state) and waits for tasks from the upper system to be issued.
[0161] After receiving a task, RGV predicts the task energy consumption and determines whether its own power is sufficient to execute the task.
[0162] If it can perform this task, the vehicle will be powered by a lithium battery when traveling at a constant speed, and the supercapacitor will assist in output during acceleration / climbing. After the task is completed, it will return to standby and enter low-energy mode.
[0163] If you cannot perform this task, pause the task and go to the charging area to charge.
[0164] When the RGV needs to be charged, it will navigate to a wireless charging point for charging. If the charging point is occupied, it will wait in line. After charging is completed, it will return to the original task or receive new instructions.
[0165] The present invention has the following beneficial effects:
[0166] 1. Traditional rail-guided vehicles (RGVs) use busbar power supply technology, which is prone to wear. Long-term friction between the busbar and the brushes can lead to poor contact, sparks, and increased maintenance costs. This invention can eliminate the mechanical wear and safety hazards of busbar power supply;
[0167] 2. The existing technology has safety hazards: it is easy to cause short circuit or leakage in harsh environments such as humidity and dust; the present invention has high reliability, uses non-contact power supply to avoid physical wear, and can operate stably in high dust and humidity environments.
[0168] 3. In existing technologies, contact resistance causes high energy loss. This invention can achieve efficient energy utilization and intelligent management. Through a hybrid energy storage system (lithium battery + supercapacitor) and wireless charging technology, energy recovery efficiency can be greatly improved, achieving high efficiency and energy saving, extending battery life and reducing maintenance costs.
[0169] 4. The present invention can be flexibly deployed without the need to lay a complex busbar network, supports dynamic path adjustment, and can improve the path planning flexibility and environmental adaptability of RGV.
[0170] 5. The present invention can realize intelligent maintenance, and the real-time monitoring system based on the Internet of Things can predict battery life and equipment failure.
