Technical Field

[0002] Existing energy storage streetlight control systems typically utilize a single battery or multiple batteries connected in series and parallel within the lamp body to achieve peak load shaving and valley load shifting. Because a single battery has a relatively small capacity, multiple batteries are connected in series and parallel to increase capacity. However, connecting batteries in series increases their voltage.

[0003] At this time, in the existing lamp circuit system, the charging voltage of the battery is fixed, and the charging voltage cannot change with the voltage of the battery pack, so the expanded battery cannot be charged.

[0004] Therefore, the existing energy storage street light control system has the following problems:

[0005] 1. Due to differences in electronic components, the output voltage and current of the charging circuit are inconsistent.

[0006] 2. Adjusting the number of batteries connected in series requires modifying the charging circuit. Utility Model Content

The accompanying drawings are only for illustrating the preferred embodiment and are not to be considered as limiting the present invention.

[0031] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0032] To simplify the drawings, only the parts relevant to the present invention are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0033] The following is a detailed description of the energy storage street lamp system with adaptive charging regulation proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0034] See Figure 1 This embodiment provides an energy storage street lamp system with adaptive charging adjustment, which includes a charging part and a discharging part. Figure 1 As an example, the modules located at the main control module and above it can be understood as the charging part of this embodiment, and the modules located at the main control module and below it can be understood as the discharging part of this embodiment.

[0035] Specifically, Figure 1 For example, the charging part includes: an AC / DC constant voltage module, a DC / DC constant voltage module, a DC / DC voltage-limiting constant current module, a charging voltage regulation module, a main control module, a battery module and a charge and discharge metering module. The AC / DC constant voltage module is electrically connected to the mains power and the DC / DC voltage-limiting constant current module respectively, and is used to convert the incoming mains power into DC constant voltage power and output it. The DC / DC voltage-limiting constant current module is electrically connected to the charge and discharge metering module, and the charge and discharge metering module is electrically connected to the battery module. The DC / DC voltage-limiting constant current module is used to receive the DC constant voltage power from the AC / DC constant voltage module, and convert it into voltage-limiting constant current power and then output it to the battery module through the charge and discharge metering module to charge the battery module. The DC / DC voltage-limiting constant current module is also connected to the main control module, and the main control module controls the output current of the DC / DC voltage-limiting constant current module by chopping to meet the charging curve of the battery module.

[0036] Next, the charging voltage regulation module is electrically connected to the main control module and the DC / DC voltage-limiting constant current module, respectively. The main control module and the charging voltage regulation module cooperate with each other to adjust the maximum output voltage of the DC / DC voltage-limiting constant current module so that the maximum output voltage of the DC / DC voltage-limiting constant current module is consistent with the voltage of the battery module. Preferably, this embodiment also includes a communication module, which is electrically connected to the main control module. The user can obtain the battery pack voltage based on the number of battery packs in the battery module and then set the charging voltage threshold in the main control module through the communication module. The charging voltage regulation module will adjust the maximum output voltage of the DC / DC voltage-limiting constant current module based on the charging voltage threshold of the main control module, thereby adjusting the maximum output voltage of the DC / DC voltage-limiting constant current module.

[0037] The charge-discharge metering module is now explained. It is electrically connected to the main control module, battery module, and DC / DC voltage-limiting constant-current module. It detects the battery module voltage and automatically feeds the detection results back to the main control module (without manually inputting a voltage threshold). This adjusts the maximum output voltage of the DC / DC voltage-limiting constant-current module. Furthermore, the charge-discharge metering module also detects the output current and voltage of the DC / DC voltage-limiting constant-current module and automatically feeds the detection results back to the main control module to prevent overvoltage or undervoltage conditions.

[0038] It is worth mentioning that this embodiment is also provided with a DC / DC constant voltage module, which is electrically connected to the AC / DC constant voltage module and the main control module respectively, can receive DC constant voltage power from the AC / DC constant voltage module, and supply power to the main control module, as well as the charging voltage regulation module and the discharging voltage regulation module electrically connected to the main control module.

[0039] Specifically, Figure 1 For example, the discharge part includes: DC / DC buck-boost constant current module, LED light source, discharge voltage regulation module and DC / DC constant current module.

[0040] The main control module is electrically connected to the discharge voltage regulation module and the DC / DC buck-boost constant current module. One end of the DC / DC buck-boost constant current module is electrically connected to the battery module via the charge and discharge metering module, while the other end of the DC / DC buck-boost constant current module is electrically connected to the LED light source. The charge and discharge metering module calculates the discharge voltage of the battery module and feeds it back to the main control module. The main control module controls the discharge voltage regulation module based on the voltage of the LED light source, converting the DC / DC buck-boost constant current module's output voltage from the battery pack into an input voltage that matches the LED light source.

[0041] In this embodiment, a DC metering module is also provided. The DC metering module is connected to the main control module, the LED light source, and the DC / DC buck-boost constant current module. The DC metering module detects the output voltage of the DC / DC buck-boost constant current module and feeds this information back to the main control module to prevent overvoltage or undervoltage conditions. The DC metering module also detects the voltage and current input to the LED light source to prevent overvoltage or overcurrent issues. If overvoltage or overcurrent occurs, the main control module controls the discharge voltage regulation module to adjust the DC / DC buck-boost constant current module to reduce the output voltage of the battery module. Furthermore, this embodiment also includes a DC / DC constant current module, which is electrically connected to the AC / DC constant voltage module, the main control module, and the DC metering module. When the battery power is off or the battery module is depleted, this circuit provides power to the LED light source. This serves as an alternative power source, with the mains power being fed to the LED light source through the AC / DC constant voltage module, the DC / DC constant current module, and the DC metering module, providing power to the LED light source. This ensures that the LED light source can continue to function properly even in the event of an abnormality.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they will still fall within the scope of protection of the present invention.
