Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle power system technology, and particularly relates to a solar-coupled energy recovery self-circulating power system and method. Background Technology

[0002] With the rapid popularization of the new energy vehicle industry, the current mainstream vehicle power systems still have three major technological shortcomings: First, traditional pure electric vehicles rely heavily on external charging piles for energy replenishment. Constrained by multiple factors such as deployment site, grid load, and driving range, it is difficult to achieve autonomous and self-sustaining operation without external charging. Second, at present, vehicle-mounted photovoltaic power generation can only achieve weak auxiliary energy replenishment function and has failed to achieve systematic coupling and linkage with various energy recovery methods such as vehicle braking energy recovery, inertial coasting energy recovery, vehicle body mechanical vibration energy recovery, and downhill gravitational potential energy recovery, resulting in low overall energy recovery and utilization efficiency. Third, existing vehicle energy recovery modes are mostly fragmented and scattered recovery under single operating conditions, lacking a unified energy coordination and scheduling mechanism, energy output priority allocation strategy, and energy closed-loop return operation logic, making it impossible to build a complete energy self-circulation system and always difficult to get rid of dependence on external energy replenishment.

[0003] Looking at the existing technical solutions in the industry, most are single-function modules used independently. They have not yet built an integrated top-level system architecture that integrates full-domain solar energy collection, multi-energy recovery under all working conditions, electromagnetic power generation in all scenarios, intelligent collaborative coupling scheduling, and energy storage buffer closed-loop operation. Furthermore, the industry lacks a truly comprehensive layout for a vehicle-mounted energy self-circulation power system that can achieve long-term stable self-sustaining operation. Summary of the Invention

[0011] Preferably, the energy priority dynamic allocation strategy includes: under normal driving conditions with sufficient sunlight, the solar energy collection module is given the first priority; under deceleration / braking / downhill / heavy load conditions, energy recovery is given the priority; electromagnetic power generation is given the priority of energy storage; and under low sunlight / nighttime conditions, the stored energy plus real-time energy recovery during driving is given the priority, maintaining self-circulation operation.

[0012] Preferably, the self-circulating control algorithm enables millisecond-level dynamic control switching between three working modes: photovoltaic priority power supply, recovered energy priority power supply, and energy storage supplementary drive, achieving full energy conservation, closed-loop reflux, and self-sustaining operation.

[0013] Preferably, the three working modes are as follows: Under normal operating conditions with sufficient sunlight, photovoltaic power is prioritized for direct drive, and excess power is stored in energy storage. Under deceleration / braking / downhill / heavy load conditions, priority is given to multi-dimensional energy recovery to convert redundant energy into electrical energy to supplement energy storage; In low light / nighttime conditions, energy storage takes priority in power supply, and electromagnetic power generation energy generated during driving is recovered simultaneously to achieve closed-loop self-circulation of energy under all operating conditions.

[0020] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-3 As shown, the present invention provides a solar-coupled energy recovery self-circulating power system, comprising: The energy supply module is used to collect and recover energy from multiple sources and convert it into electrical energy. The energy coupling voltage regulator module is used to combine, regulate, filter, and match the multi-source electrical energy (photovoltaic power and various recycled miscellaneous power) provided by the energy supply module, and output standard DC power in a unified manner, which is then connected to the intelligent control and scheduling module and the energy storage buffer module respectively. The intelligent control and scheduling module is used to dynamically control and distribute electrical energy to the power drive module based on the vehicle's real-time operating conditions, lighting conditions, and remaining energy storage capacity, while forming an energy closed-loop return flow to achieve self-circulating and self-sustaining operation of the vehicle's energy. Energy storage buffer modules are used for instantaneous energy storage to smooth out power fluctuations, including power battery packs and supercapacitor packs; The power drive module is used to provide driving power for the whole vehicle and is compatible with electric motor drive, gasoline, diesel, ammonia, methanol engine linkage drive, and hybrid coupling drive. The operating condition signal acquisition module is used to collect vehicle speed, throttle opening, braking signal, slope, light intensity, and battery SOC status in real time, and feed them back to the intelligent control and scheduling module.

[0023] Each module is connected and linked sequentially according to the energy flow direction, forming a closed-loop recirculation architecture. Self-circulation means that the vehicle relies on solar energy and energy recovery under normal driving conditions to be self-sufficient, and electromagnetic power generation to supplement energy, so it can operate continuously without long-term dependence on external charging or fuel refueling.

[0024] In one specific embodiment provided in this application, the energy supply module includes: A solar energy harvesting module is used to collect solar energy and convert it into electrical energy around the clock. A multi-dimensional energy recovery module is used to capture and collect redundant mechanical energy and waste heat energy generated by vehicle driving, braking, coasting, ramping, and vibration. The electromagnetic power generation module is used to generate magnetic cutting power during energy recovery, directly converting mechanical energy into electrical energy and storing it in the energy storage buffer module.

[0025] The outputs of the solar energy acquisition module, electromagnetic power generation module, and multi-dimensional energy recovery module are all connected to an energy coupling and voltage regulation module. After the electrical energy is uniformly fed into the energy coupling and voltage regulation module, the multi-source chaotic electrical energy is collected, regulated, and then connected to the intelligent control and scheduling module and the energy storage buffer module respectively. After intelligent scheduling, it is distributed to subsequent units. The operating condition signal of the power drive module is first fed back to the intelligent control and scheduling module, which adjusts the energy distribution strategy in real time according to the operating condition. Then, the scheduling module sends recovery control commands to the multi-dimensional energy recovery module to form a closed-loop control. This system is suitable for both pre-installation integration in vehicles and retrofitting of existing vehicles, and is compatible with any application scenario of pure electric vehicles, hybrid vehicles, methanol-powered vehicles, fuel vehicles, and mobile special power equipment.

[0026] Furthermore, the electromagnetic power generation module is a key unit independent of the multi-dimensional energy recovery module. Its core principle is to use the phenomenon of electromagnetic induction to cut magnetic lines of force through the relative motion between the conductor coil and the permanent magnet, directly converting mechanical energy into electrical energy. The electrical energy output by this module is rectified and regulated before being sent to the energy storage buffer module for storage, providing supplementary power to the system. It is an important independent unit for realizing energy recovery and self-circulation.

[0027] In one specific embodiment provided in this application, the electromagnetic power generation module is a coaxial synchronous embedded electromagnetic self-generating module based on the inherent rotating components of the power system. It relies on the original rotating components of vehicles and industrial power equipment, and a permanent magnet magnetic field array is embedded and fixedly set on the outer periphery of the original rotating components. A stationary induction coil assembly is embedded and arranged coaxially with the permanent magnet magnetic field array. Through the coaxial synchronous rotation of the original rotating components during normal operation of the power equipment, the stationary induction coil assembly cuts the magnetic field lines of the permanent magnet magnetic field to generate induced electrical energy. There is no need to add an additional power drive mechanism, and no reliance on exhaust waste heat, road vibration and braking kinetic energy for energy recovery. It achieves follow-up synchronous continuous electromagnetic power generation without increasing the overall power load or changing the original power transmission structure. It is suitable for various fuel, methanol, hybrid and pure electric power equipment and general industrial power equipment.

[0028] In one specific embodiment provided in this application, the solar energy collection module includes: a detachable external photovoltaic car cover covering any position of the vehicle body, and independent detachable photovoltaic modules installed on the vehicle body, roof, and sides of the vehicle body. The photovoltaic modules include, but are not limited to, perovskite tandem photovoltaic, crystalline silicon photovoltaic, and Fresnel lens energy-concentrating and efficiency-enhancing modules.

[0029] In one specific embodiment provided in this application, the multi-dimensional energy recovery module includes any one or more combinations of electromagnetic power generation recovery, braking energy recovery, coasting inertia energy recovery, vehicle body driving vibration mechanical energy recovery, chassis hydraulic vibration energy recovery, ramp potential energy recovery, and exhaust waste heat recovery, so as to realize the capture and recovery of redundant energy under all working conditions.

[0030] In one specific embodiment provided in this application, the intelligent control scheduling module incorporates a working condition identification logic program, a charge / discharge protection logic strategy, an energy priority dynamic allocation strategy, and a self-loop control algorithm.

[0031] Furthermore, the basic units of the intelligent control and scheduling module (such as conventional operating condition logic, general charging and discharging protection, simple energy allocation, and single-link closed-loop control) are existing mature technologies and will not be described further here. The core innovation of this invention lies in addressing the limitations of existing energy management strategies, which cannot adapt to complex operating conditions and struggle to achieve a complete energy closed loop. For the first time, this invention integrates these general control logics with a customized closed loop across the entire energy chain, encompassing solar energy harvesting, multi-source energy recovery, energy coupling voltage regulation, and energy storage buffering. It also adds a dynamic energy priority allocation strategy and a self-circulating control algorithm for multi-operating condition switching. By real-time acquisition of light intensity, vehicle driving conditions, energy storage status, and the output power of each energy recovery module, it dynamically switches the weights of photovoltaic priority, recovery priority, and energy storage replenishment modes in milliseconds. A closed-loop control system covering the entire energy flow chain, including solar energy collection, multi-source energy recovery, energy coupling and voltage stabilization, energy storage buffering, and power drive, has been established. This system achieves zero energy waste and closed-loop self-operation under all operating conditions. For example, during uniform cruising under strong sunlight, the system prioritizes solar power and stores the energy recovered by electromagnetic generation in the energy storage. When the battery is low on a long downhill slope, the system automatically switches to a recovery priority mode to store the slope potential energy. During rapid acceleration at night without sunlight, the system prioritizes real-time recovery of electrical energy and then replenishes the energy from the energy storage. Through dynamic scheduling and full-link closed-loop control under different operating conditions, the feasibility of the customized integration solution has been verified.

[0032] In one specific embodiment provided in this application, the energy priority dynamic allocation strategy includes: under normal driving conditions with sufficient sunlight, the solar energy collection module is given the first priority; under deceleration / braking / downhill / heavy load conditions, energy recovery is given the priority; electromagnetic power generation is given the priority of energy storage; and under low sunlight / nighttime conditions, the stored energy plus real-time energy recovery during driving is given the priority, thus maintaining self-circulation operation.

[0033] In one specific embodiment provided in this application, by collecting multi-dimensional operating condition data in real time, the self-circulating control algorithm realizes millisecond-level dynamic control switching of three working modes for multiple operating conditions: photovoltaic priority power supply, recovered energy priority power supply, and energy storage supplementary drive, so as to achieve energy conservation, closed-loop return, and self-sustaining operation throughout the process.

[0034] In one specific embodiment provided in this application, the three working modes are as follows: Under normal operating conditions with sufficient sunlight, photovoltaic power is prioritized for direct drive, and excess power is stored in energy storage. Under deceleration / braking / downhill / heavy load conditions, priority is given to multi-dimensional energy recovery to convert redundant energy into electrical energy to supplement energy storage; In low light / nighttime conditions, energy storage takes priority in power supply, and electromagnetic power generation energy generated during driving is recovered simultaneously to achieve closed-loop self-circulation of energy under all operating conditions.

[0035] Furthermore, the intelligent control and scheduling module of the present invention, through its built-in operating condition identification logic, energy priority allocation strategy and charge and discharge protection strategy, integrates and analyzes the real-time collected data on light intensity, vehicle operating condition and battery status, and dynamically switches between three working modes: photovoltaic priority power supply, energy recovery priority and energy storage supplementation drive, to achieve closed-loop management, safety protection and efficient self-circulation operation of energy under all operating conditions.

[0036] This invention also provides a solar-coupled energy recovery self-circulating power method, comprising the following steps: S1. Real-time collection of lighting and vehicle operating condition information, and feedback to the intelligent control and scheduling module; S2, the intelligent control and scheduling module judges the intensity of sunlight and driving conditions, and dynamically controls the switching between three working modes: photovoltaic priority power supply, energy recovery priority power supply, and energy storage supplementary drive. Under normal operating conditions with sufficient sunlight, photovoltaic power is prioritized for direct drive, and excess power is stored in energy storage. Under deceleration / braking / downhill / heavy load conditions, priority is given to multi-dimensional energy recovery to convert redundant energy into electrical energy to supplement energy storage; In low light / nighttime conditions, energy storage takes priority to supply power, and electromagnetic energy generated during driving is recovered simultaneously; S3. The loop returns to step S1 for real-time data acquisition and continues to run in a self-looping manner.

[0037] Furthermore, under normal operating conditions: the solar energy acquisition module generates electricity in real time, which is prioritized for supplying the power drive module, and any excess electricity is stored in the energy storage buffer module; Deceleration / braking conditions: The photovoltaic priority power supply is cut off, and braking energy recovery and inertial coasting recovery are switched on. All redundant energy flows back to the energy storage buffer module. Downhill / Heavy load conditions: Simultaneous activation of potential energy recovery + chassis vibration hydraulic recovery, coupled with solar power generation; Low light / nighttime operation: The main output of photovoltaic power is turned off, and the self-circulation operation is maintained by relying on the energy stored during the day and the real-time energy recovery during driving.

[0038] This invention utilizes an intelligent control and scheduling module to automatically and seamlessly switch between three operating modes based on real-time data collected on light intensity, vehicle operating conditions, and battery status: when there is sufficient sunlight, photovoltaic power is prioritized for direct drive, and excess electrical energy is stored in energy storage; during braking / downhill conditions, multi-dimensional energy recovery is prioritized to convert redundant energy into electrical energy to supplement energy storage; and during low light / nighttime conditions, energy storage is prioritized for power supply, and energy generated during driving, such as electromagnetic power generation, is simultaneously recovered, achieving closed-loop self-circulation of energy under all operating conditions.

[0039] Compared with existing technologies, this invention provides dual-source power through a solar energy acquisition module and a multi-dimensional energy recovery module. After coupling and stabilizing, intelligent scheduling, and energy storage buffering, the energy drives the entire vehicle. At the same time, it realizes closed-loop energy return under working conditions, solving the pain point of traditional vehicles relying on external charging and fuel replenishment. It can achieve full vehicle model compatibility and long-term energy self-circulation, and is suitable for various new energy and special power equipment applications such as pure electric vehicles, hybrid electric vehicles, methanol-powered vehicles, commercial special vehicles, and mobile power equipment.

[0040] This invention achieves a closed-loop self-circulation of the vehicle's energy internally through continuous solar energy harvesting, full-range waste energy recovery under all operating conditions, multi-source energy coupling and convergence, and intelligent energy distribution and management, which can reduce or even eliminate the need for external energy replenishment in the long term.

[0041] This invention achieves a full-condition energy self-circulation result that has never been achieved by existing technologies. By integrating multiple recovery paths such as electromagnetic power generation, braking, coasting, vehicle vibration, hydraulic empowerment, slope potential energy, and exhaust waste heat with solar energy collection, energy coupling voltage stabilization, and intelligent scheduling algorithms in a closed-loop system, it achieves a full-condition energy self-circulation result that has never been achieved by existing technologies.
