Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
As shown in fig. 1, a first aspect of the present embodiment provides a mobile stereoscopic light energy storage charging method, which includes the following steps:
step S100, mounting a light energy storage unit with a plurality of light receiving areas on the surface of the mobile device, wherein each light receiving area is provided with a photoelectric converter and an energy storage element;
on the outside of a mobile device (e.g., car, cell phone, tablet computer, etc.), a special device is installed, which includes a plurality of light receiving areas. Each light receiving region is equipped with a photoelectric converter and an energy storage element. The light receiving area is an area for receiving light energy, which can convert the received light energy into electric energy through a photoelectric converter, and store it in an energy storage element. Thus, each light receiving region is capable of independently converting light energy into electrical energy and storing it.
Step 200, when the mobile device is exposed to light, the received light energy is respectively converted into electric energy through respective photoelectric converters and is temporarily stored in respective energy storage elements;
in this step, when the mobile device is exposed to light, the photoelectric converter in the light receiving area converts light energy into electrical energy. Each light receiving region is provided with its own photoelectric converter, and thus can independently convert received light energy into electric energy. The converted electrical energy is temporarily stored in the respective energy storage element. The energy storage element may be a battery or similar device for temporarily storing electrical energy drawn from the light receiving area to provide a source of energy for a subsequent charging process.
Step S300, detecting each light receiving area and judging whether the corresponding energy storage element reaches a preset charging condition;
step S400, if the energy storage element in a certain light receiving area reaches a preset charging condition, entering the next step, otherwise, continuing to execute step S200;
in this step, each light receiving area is detected in order to determine whether the amount of electricity in the energy storage element has satisfied a preset charging condition. The charging condition may be a particular charge threshold or other relevant parameter. By detecting the light receiving areas, the system can acquire the electric quantity condition of the energy storage element corresponding to each light receiving area. Then, according to the preset charging condition, the system determines whether the energy storage element has reached or exceeded the preset charging condition. If the energy storage element in a certain light receiving area reaches the preset charging condition, the system will enter the next step (step S500) to start the corresponding charging control and energy delivery operation. If the energy storage element does not reach the preset charging condition, the system returns to step S200 to continue receiving the light energy and storing the electric energy for further charging.
Step S500, starting a corresponding charging control unit, and dividing the electric energy in the energy storage element into a plurality of small sections to be transmitted to a main battery of the equipment;
in this step, the system activates a specific charge control unit when the charge of the energy storage element has met a preset charge condition. The charging control unit is responsible for managing and monitoring the energy delivery process to ensure efficient and safe transfer of electrical energy to the main battery of the device. In order to improve the efficiency and stability of energy transfer, the electrical energy in the energy storage element is subdivided into a plurality of small segments for delivery. This staged approach reduces energy losses and better accommodates the charging requirements of the device.
Step S600, in the charging process, adjusting the electric energy transmission rate of the charging control unit according to the difference value between the current electric quantity of the main battery and the preset electric quantity;
in this step, the system monitors the current power of the main battery and a preset target power. By comparing the difference between the two, the system can determine the state of charge and demand of the main battery. The charge control unit will adjust the rate of delivery of electrical energy according to the difference, depending on the state of charge of the main battery. If the electric quantity of the main battery is lower than the preset electric quantity, the charging control unit can increase the electric energy transmission rate so as to accelerate the charging progress and enable the main battery to reach the preset electric quantity as soon as possible. In contrast, if the main battery power approaches or has reached the preset power, the charge control unit may reduce the power delivery rate to avoid overcharging or wasting energy. By dynamically adjusting the power delivery rate, the system can achieve precise control over the charging process to meet the power requirements of the device and to protect the health of the main battery. The regulation mechanism can ensure that the charging process is performed efficiently and safely, and simultaneously prolong the service life of the main battery to the maximum extent and avoid the occurrence of overcharge or insufficient electric quantity.
Step S700, when all the energy storage elements in the light receiving areas do not reach the preset charging condition, continuing to execute step S200 to wait for a proper illumination condition;
step S800, when the electric quantity of the main battery of the equipment is lower than the preset electric quantity, charging by using the electric energy in the optical energy storage unit;
and step 900, stopping the charging process when the electric quantity of the main battery of the equipment reaches the preset electric quantity or the illumination condition is not met.
Steps S700 to S900 are charging process control steps in the optical energy storage system. In these steps, the system decides whether to continue or stop charging according to the following conditions.
For example, in step S700, the light energy received by the light receiving area is insufficient to meet the charging requirement of the energy storage element, so the system needs to wait for better lighting conditions in order to continue charging. Once the illumination condition is satisfied, in step S800, the light energy storage unit supplements the main battery of the device with electric energy, so that the electric quantity thereof is gradually restored to the preset level. Finally, in step S900, the device main battery is already full or cannot continue to draw sufficient power from the optical energy storage unit, so the charging process is terminated.
By controlling the steps, the light energy storage system can accurately control the charging process according to the illumination condition and the electric quantity state of the main battery of the device. The system waits for proper lighting conditions to occur and then charges the device main battery with the electrical energy in the optical energy storage unit until a preset amount of electrical energy is reached or charging cannot be continued. The control strategy ensures the effectiveness and safety of charging and maximally utilizes available light energy resources.
In the embodiment, according to the difference between the current electric quantity of the main battery and the preset electric quantity, the electric energy transmission rate of each small section of charging is adjusted; when the electric quantity of the main battery is lower than a preset value, the electric energy transmission rate of charging is increased to rapidly charge; and when the electric quantity of the main battery is close to the preset electric quantity, reducing the electric energy transmission rate of charging. According to the method, intelligent adjustment is performed according to the electric quantity difference, and the charging process is optimized, so that the efficiency is improved, and the time is saved. The electric quantity is rapidly supplemented by increasing the electric energy transmission rate, so that the main battery can reach the preset electric quantity as soon as possible. And when approaching the preset amount of electricity, reducing the charge rate can avoid overcharge, thereby protecting the main battery and improving its life.
In this embodiment, dividing the electrical energy in the energy storage element into a plurality of segments for delivery to the main battery of the device comprises:
step S501, determining the total amount of electric energy to be transported in a segmented manner;
step S502, the total electric energy is divided into a plurality of small sections in an average way, and the electric energy of each small section is determined;
step S503, starting a charging control unit, and sequentially transmitting electric energy to a main battery of the equipment according to a preset transmission rate and the electric energy of each small section;
step S504, detecting a difference value between the current electric quantity of the main battery and the preset electric quantity after each small section of electric energy is conveyed;
step S505, adjusting the electric energy transmission rate of the next small section according to the difference value; if the difference is large, increasing the conveying rate to charge rapidly; if the difference is close to zero or is negative, reducing the conveying speed;
step S506, repeating the steps S503 to S505 until all the small sections of electric energy are transmitted to the main battery or reach the preset electric quantity;
and S507, stopping the charging process when all the small sections of electric energy are transmitted to the main battery or the electric quantity of the main battery reaches the preset electric quantity.
It can be appreciated that the energy in the energy storage element is divided into a plurality of small segments for being delivered to the main battery of the device, so that the energy utilization efficiency can be improved, because the smaller electric energy segments can more accurately meet the charging requirement of the device, and the energy waste is reduced. Second, segmented delivery can increase the stability and reliability of the energy delivery because even if an anomaly or disturbance occurs during the energy delivery, only the small segment currently being delivered is affected without severely affecting the overall charging process. In addition, the sectional conveying can reduce the heat generation during charging and reduce the heat load of the equipment, so that the safety and the sustainability of charging are improved. Finally, the charging characteristics of the main battery of the device, such as battery capacity, voltage limitation and the like, can be better matched through sectional conveying, so that the charging process is ensured to be in accordance with the optimal charging curve of the main battery of the device, the service life of the battery is prolonged, and the charging effect is improved.
Preferably, a light energy power generation system is assumed, comprising three light receiving areas (A, B and C) and corresponding energy storage elements for storing light energy.
In step S300, it is monitored and determined whether the energy storage element of each light receiving area reaches a preset charging condition. Meanwhile, the charging state and the electric energy storage amount of the energy storage elements in each light receiving area are also monitored.
Now, it is assumed that during the detection process, it is found that the energy storage element of the light receiving area a has reached the preset charging condition. Before proceeding to step S400, the following steps are performed:
step S401: and recording the current electric energy storage amount of the energy storage element in the light receiving area A. The current state of charge and the power reserve of the light-receiving area a can thus be known.
Step S402: and determining a target electric energy storage range according to the electric energy storage conditions of the energy storage elements of the other light receiving areas B and C. The electric energy storage amount of each light receiving area is relatively close to realize equalizing charge.
Step S403: and adjusting the charging rate of the light receiving area A to enable the charging rate to reach the target electric energy storage range in the preset time, and synchronously carrying out the charging process with other light receiving areas. This ensures that the charging process of the light receiving area a is coordinated with that of the other light receiving areas and reaches the target charging level in a reasonable time.
Thereafter, steps S500 to S507 are continued to be performed, and the electric energy in the energy storage element is transferred to the main battery of the device in segments according to the electric energy storage amount distribution scheme. By the method, the effective distribution and utilization of the light energy can be realized according to the electric energy storage condition of each light receiving area and the preset target, and the charging efficiency and performance of the system are improved to the greatest extent.
Preferably, in step S900, when the power of the main battery of the device reaches the preset power or the lighting condition is no longer satisfied, the charging process is stopped, and the following steps are performed:
step S901: and recording the electric energy storage capacity of the energy storage element which is not charged in the current light energy storage unit. These energy storage elements are parts that have not yet been charged.
Step S902: and recording the electric energy storage capacity of the energy storage element which is not charged as standby electric energy. The electrical energy stored in these energy storage elements may be supplied as a backup for use when charging cannot continue or other needs.
Step S903: the backup power is delivered to the main battery of the device as needed. The previously recorded electric energy in the uncharged energy storage element is utilized to be conveyed to a main battery of the equipment so as to meet the energy requirement of the equipment.
Through the steps, the uncharged energy storage element in the optical energy storage system can be effectively managed, and the electric energy storage capacity of the uncharged energy storage element is used as standby electric energy. Therefore, when the main battery of the equipment reaches the preset electric quantity or the illumination condition is not met, the charging process can be stopped in time, and the normal operation of the equipment is maintained by using the standby electric energy.
Preferably, the method comprises the following steps performed before step S800:
step S801, monitoring the electric quantity of a main battery of the equipment;
step S802, determining a preset electric quantity as a target electric quantity of a main battery of the equipment;
step 803, if the electric quantity of the main battery of the device is lower than the preset electric quantity, the electric energy in the optical energy storage unit is directly transmitted to the main battery of the device for quick charging;
step S804, when the electric quantity of the main battery of the device reaches the preset electric quantity, the method proceeds to step S500 to continue charging according to the segmented conveying mode.
Preferably, in step S200, the received light energy is converted into electric energy by respective photoelectric converters, and stored in respective energy storage elements temporarily, while recording the corresponding light energy conversion efficiency of each light receiving area.
Preferably, in step S700, when all the energy storage elements in the light receiving areas do not reach the preset charging condition, step S200 is continued to wait for an appropriate illumination condition, and the illumination intensity is monitored to determine the charging opportunity.
