Description

Technical Field

[0001] The present invention relates to the field of charging technology, and in particular to a charging pile utilizing solar energy to supply power. Background Art

[0002] Existing charging piles mainly rely on the mains electricity supply. Although the mains electricity supply is relatively stable, the mains electricity price is affected by many factors, including energy market fluctuations, power generation costs, and transmission and distribution costs. Long-term use of mains electricity to power charging piles has high operating costs, which is a considerable expense for charging pile operators.

[0003] In some remote areas or places with weak power infrastructure, access to city electricity is difficult and costly, and large-scale grid transformation and line laying projects may be required, which not only consumes a lot of money and time, but may also be impossible to achieve in areas with complex geographical conditions.

[0004] Solar energy is one of the most abundant renewable energy sources on earth, and photovoltaic power generation technology is mature and widely used. Therefore, solar energy can be used as an important energy source for charging piles.

[0005] At present, the technology of solar energy supply charging pile has been disclosed. For example, a Chinese patent with publication number CN206598741U discloses a charging pile using new energy storage, which includes a charging pile body, solar panel I, solar panel bracket, solar automatic tracker, solar panel II, touch display, IC card reader, microprocessor, charging port, rain shield, rain cover, base bracket, base, power storage, and the new energy storage device contains solar panel I, solar panel II and power storage.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0039] Example 1

[0040] like Figure 1 , Figure 4 As shown, in order to avoid the battery from occupying a large space after the photovoltaic technology is applied to the charging pile, and to reduce the impact of the low temperature environment on it, and to correspondingly improve the installation efficiency of the charging pile, this embodiment provides a new charging pile technical solution. The technical solution includes a charging pile body 1, a solar panel 2, a storage component 3, etc. The solar panel 2 is arranged above the charging pile body 1, and the storage component 3 is arranged below the charging pile body 1, and includes a plurality of batteries 33. To install the above-mentioned charging pile, a pit similar in appearance to the storage component 3 is excavated at the installation site, and then the storage component 3 is placed in the pit, and filled with materials such as gravel to enhance the stability of the storage component 3 and the pit, so that the charging pile can be stably installed, changing the method of pre-casting concrete, while avoiding the battery 33 from occupying a large ground space, and the storage component 3 can be insulated through the soil to reduce the impact of low temperature on the battery 33.

[0041] The technical solution of the charging pile body 1 has been disclosed, and is briefly introduced here. It includes a charging module, a charging gun, a control unit, a communication module, a metering and billing unit, a protection device, a display module, etc.

[0042] The charging module is one of the core components of the charging pile. Its main function is to convert the input AC power into DC power that meets the charging requirements of electric vehicle batteries. Its working principle is achieved through circuit links such as rectification, filtering and power conversion. For example, in a charging module using high-frequency switching power supply technology, AC power is first rectified into DC power, and then the voltage and current are converted through components such as high-frequency transformers and switching tubes to output appropriate DC charging voltage and current.

[0043] The shell of the charging gun is generally made of high-strength engineering plastics with good insulation properties, and there is a conductive core wire inside for transmitting electrical energy.

[0044] The control unit includes a main control board, a communication module, etc. The main control board is the "brain" of the charging pile, which is responsible for coordinating and controlling the various components of the charging pile. Through the pre-written control program, the main control board can achieve precise management of the charging process. For example, it can control the charging module to output the appropriate charging voltage and current according to factors such as the type of electric vehicle battery, the remaining power and the charging demand. The main control board can also monitor the charging status in real time. Once an abnormal situation is found, such as overcurrent, overvoltage, short circuit, etc., it will immediately take protective measures, such as cutting off the charging circuit, to ensure charging safety. The communication module (which can be set as a Wi-Fi module, 4G / 5G module, etc.) is used for information exchange between the charging pile and external devices. On the one hand, it can communicate with the battery management system of the electric vehicle to obtain real-time information of the battery, such as battery temperature, SOC (state of charge), etc., and feed this information back to the main control board to adjust the charging strategy. On the other hand, the communication module can also realize the remote communication function and upload the operation data of the charging pile to the cloud server.

[0045] The metering and billing unit includes an electric meter and a billing system. The electric meter is used to accurately measure the charging power of electric vehicles. It obtains the value of the charging power by integrating the charging current and the charging time. The billing system calculates the user's charging fee based on the data measured by the electric meter and the preset electricity price standard. There are many billing methods, such as billing according to the charging power, charging time, or time-of-use electricity price. The billing system can be integrated with the payment system to support multiple payment methods, such as swiping cards, scanning code payment, etc., to facilitate users to pay charging fees.

[0046] Protection devices include overcurrent protection devices, overvoltage protection devices, etc. When overcurrent occurs during charging, the overcurrent protection device will automatically cut off the circuit to prevent damage to the charging equipment and electric vehicle batteries. Common overcurrent protection devices include fuses and circuit breakers. Overvoltage protection devices are used to prevent damage to the battery due to excessive charging voltage. It usually uses components such as varistors and transient suppression diodes. When the voltage exceeds the set threshold, these components will quickly turn on and bypass the overvoltage, thereby protecting subsequent circuits.

[0047] The display module includes a display screen, indicator lights, etc. The display screen is used to display charging information to the user, such as charging status (charging, fully charged, charging paused, etc.), charging power, charging time, estimated full time, charging cost, etc. The size and clarity of the display screen vary depending on the type of charging pile and the application scenario. The indicator lights can intuitively display the working status of the charging pile, such as the power indicator light indicates whether the charging pile is powered on, the charging indicator light is on during charging, and the fault indicator light flashes when a fault occurs.

[0048] In order to convert solar energy into electrical energy, a charging controller is required between the solar panel 2 and the battery 33 connected by wires. The main function of the charging controller is to adjust the electrical energy output by the solar panel to prevent overcharging and over-discharging of the battery. It can automatically adjust the charging current and voltage according to the charging state of the battery. For example, when the battery voltage is close to full, the charging controller will gradually reduce the charging current to avoid overcharging. At the same time, the charging controller can also prevent the battery from over-discharging during the discharge process, thereby extending the service life of the battery.

[0049] According to the disclosed technology, in order to provide the electric energy of the battery 33 to the charging pile body 1, a voltage conversion device (such as a DC-DC converter), an overcurrent protection device (such as a fuse or a circuit breaker), etc. need to be connected between the battery 33 and the charging pile body 1, that is, the corresponding equipment is installed according to actual needs. In short, power supply must be achieved. The voltage conversion device increases the voltage of the battery to a range that the charging pile can accept. The control unit will adjust the charging process according to the state of the battery and the charging needs of the electric vehicle. For example, when the battery power is low, the control unit may first use a constant current charging method to quickly charge the battery with a larger current; when the battery voltage is close to full, it switches to a constant voltage charging method, gradually reducing the charging current to prevent overcharging.

[0050] The control unit of the charging pile monitors the voltage and current of the input power supply in real time. The control unit obtains the voltage and current signals of the mains through the voltage transformer and the current transformer. For the battery, since its voltage changes with the change of power, the control unit also uses the voltage detection circuit to monitor the voltage of the battery, and uses the current detection circuit to determine whether the output current of the battery is within the normal range.

[0051] The control unit will determine which energy source is available based on preset rules. For example, when the mains voltage is within the normal fluctuation range (generally ±10%-15% fluctuation is allowed) and there is no short circuit, open circuit or other faults in the mains line, the mains is considered to be available. For batteries, when the battery voltage is higher than the minimum operating voltage (this value depends on the battery type and charging pile requirements, such as for a 12V lead-acid battery, it may be set to around 10.5V) and can provide sufficient current to meet charging requirements, it is determined that the battery can be used as a power source.

[0052] The control unit can set the priority of energy use. For example, the mains power is set as the priority energy source. When the mains power is normal, the mains power circuit is connected by controlling the relay, so that the charging pile uses the mains power for charging. At this time, the control unit will continue to monitor the mains power status. Once the mains power is cut off or fails, it will automatically switch to battery power supply. The specific operation is that the control unit sends a signal to the relay drive circuit to close the relay connected to the battery and connect the battery to the charging circuit.

In addition, under the action of heat conduction, the low temperature of the soil can be used to reduce the temperature in the box body 31.
