Description

Technical Field

[0001] This utility model relates to the field of power energy storage technology, specifically an energy storage device applied to a new type of power system. Background Technology

[0002] Currently, existing energy storage devices used in power systems, especially battery energy storage devices used in low-temperature environments, generally suffer from poor low-temperature adaptability. Under cold climate conditions, the internal chemical reaction rate of energy storage batteries will decrease significantly, leading to increased internal resistance and reduced discharge capacity. In severe cases, they may even fail to start up or supply power normally, affecting the stable operation of the power system.

[0003] In existing technologies, although some energy storage devices have adopted insulation measures, they often lack active and controllable heating functions, making it difficult to accurately adjust the temperature according to the actual battery temperature. For example, some devices rely solely on external insulation layers or simple heating elements for passive insulation, which cannot quickly raise the battery temperature to a suitable operating range during the low-temperature start-up phase, nor can it stop heating in time after the temperature rises, easily leading to energy waste or the risk of battery overheating.

[0004] To address these issues, those skilled in the art have proposed an energy storage device for novel power systems. Summary of the Invention

[0005] The purpose of this invention is to provide an energy storage device for use in new power systems, in order to solve the problem that energy storage batteries in the prior art suffer from reduced performance and difficulty in starting up due to the lack of an effective and controllable heating mechanism in low-temperature environments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy storage device for a novel power system, comprising an energy storage device housing, an outer fixing frame installed on the outer side wall of the energy storage device housing, and multiple energy storage batteries installed on the inner side of the energy storage device housing and the outer fixing frame.

[0007] A heating mechanism is provided on the outer side wall of the energy storage battery. The heating mechanism includes a central baffle, which is fixedly connected to the inner side wall of the energy storage device housing. Heating pads are installed on the two side walls of the central baffle and the inner side wall of the energy storage device housing. Heating wires are provided on the surface of the heating pads for heating the energy storage battery.

[0008] Preferably, a top baffle is installed on the top of the inner wall of the energy storage device housing, and multiple copper contacts are installed on the top of the outer fixing frame. Multiple mounting grooves are opened on the top of the top baffle corresponding to the positions of the copper contacts.

[0009] Preferably, a temperature detection unit is installed on the top of the top baffle, and the temperature detection unit is connected to the heating pad via a wire.

[0010] Preferably, a heat dissipation mechanism is provided at the bottom of the energy storage device housing, the heat dissipation mechanism includes a supporting base plate, and a placement groove is provided on the inner side of the bottom of the energy storage device housing.

[0011] Preferably, a support base plate is fixedly connected to the placement slot inside the housing of the energy storage device, a drive motor is installed on the top of the support base plate, and a connecting fan blade is fixedly connected to the output end of the drive motor.

[0012] Preferably, the connecting fan blades are multiple and correspond to the number of energy storage batteries, and are used to dissipate heat from the bottom of the energy storage batteries.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model incorporates a heating mechanism consisting of a central baffle, a heating pad, and heating wires, which are tightly attached to the outer wall of the energy storage battery. This structure can actively and directly heat the battery in low-temperature environments, effectively increasing the battery temperature, reducing its internal resistance, and ensuring that the energy storage battery can still start up quickly and maintain efficient and stable performance in cold climates. This fundamentally improves the shortcomings of existing energy storage devices in terms of low-temperature adaptability.

[0015] 2. By setting a top baffle, copper contacts and corresponding placement slots, this utility model not only improves the integrity and stability of the internal structure, but also provides regular and reliable electrical connection points for each energy storage battery module, which facilitates installation and maintenance and ensures the stability of current transmission.

[0016] 3. This utility model introduces active heat dissipation capability into the energy storage device by setting a heat dissipation mechanism at the bottom of the device housing, which includes a supporting base plate, a drive motor, and connecting fan blades. When the battery temperature is too high during operation, this mechanism can effectively force air cooling, accelerate heat dissipation, prevent battery performance degradation or damage due to overheating, and extend battery life.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] Example 1: This utility model provides an energy storage device for a novel power system, including an energy storage device housing 1, an outer fixing frame 11 installed on the outer side wall of the energy storage device housing 1, and a plurality of energy storage batteries 12 installed on the inner side of the energy storage device housing 1 and the outer fixing frame 11.

[0027] A heating mechanism is provided on the outer side wall of the energy storage battery 12. The heating mechanism includes a central baffle 24, which is fixedly connected to the inner side wall of the energy storage device housing 1. Heating pads 25 are installed on the two side walls of the central baffle 24 and the inner side wall of the energy storage device housing 1. Heating wires 26 are provided on the surface of the heating pads 25 for heating the energy storage battery 12.

[0028] During operation, the operator first connects the device to the power supply. The control unit (which can be an STM32F103 series microcontroller) monitors the system status in real time. When the ambient temperature is lower than the set threshold, the control unit outputs a PWM signal to drive the heating pad 25 to work. The heating pad 25 uses a silicone rubber heating sheet, and the heating wire 26 inside it uses a nickel-chromium alloy resistance wire. It heats the energy storage battery 12 evenly through the principle of resistance heating. This working principle enables the rapid heating of the energy storage battery 12 in a low-temperature environment, ensuring that the battery operates within the optimal temperature range.

[0029] 1. In one embodiment of the present invention, a top baffle 2 is also installed on the top of the inner side wall of the energy storage device housing 1, and a plurality of copper contacts 23 are installed on the top of the outer fixing bracket 11, and a plurality of mounting grooves 21 are opened on the top of the top baffle 2 corresponding to the positions of the copper contacts 23.

[0030] During operation, after the staff first installs the energy storage battery 12 into place, the copper contact 23 automatically embeds into the mounting slot 21 to form an electrical connection. This working principle enables the rapid installation and reliable connection of the battery module, improves assembly efficiency, and ensures the stability of the circuit connection.

[0031] 2. In one embodiment of the present invention, a temperature detection unit 22 is installed on the top of the top baffle 2, and the temperature detection unit 22 is connected to the heating pad 25 through a wire.

[0032] During operation, the staff first collects the surface temperature of the energy storage battery 12 in real time through the temperature detection unit 22 (using a DS18B20 digital temperature sensor) and transmits the temperature signal to the control unit. The control unit controls the start and stop of the heating pad 25 according to the preset temperature threshold (such as 0℃). Through this working principle, accurate monitoring and intelligent control of battery temperature are achieved, avoiding energy waste and the risk of battery overheating.

[0033] 3. In one embodiment of the present invention, a heat dissipation mechanism is provided at the bottom of the energy storage device housing 1. The heat dissipation mechanism includes a supporting base plate 3, and a placement groove is provided on the inner side of the bottom of the energy storage device housing 1.

[0034] During operation, when the temperature detection unit 22 detects that the battery temperature exceeds the set upper limit (e.g., 45°C), the control unit activates the heat dissipation mechanism. This working principle provides an overheat protection mechanism for the system, ensuring stable operation of the device in high-temperature environments.

[0035] 4. In one embodiment of the present invention, a support base plate 3 is fixedly connected in the placement slot inside the outer shell 1 of the energy storage device, a drive motor 31 is installed on the top of the support base plate 3, and a connecting fan blade 32 is fixedly connected to the output end of the drive motor 31.

[0036] During operation, the operator first starts the drive motor 31 (using a DC24V brushless motor) through the control unit. The motor drives the connected fan blades 32 to rotate, generating forced convection. This working principle enables efficient active cooling of the energy storage battery 12, significantly improving the heat dissipation efficiency.

[0037] 5. In one embodiment of the present invention, the connecting fan blades 32 are multiple and correspond to the number of energy storage batteries 12, and are used to dissipate heat from the bottom of the energy storage batteries 12.

[0038] During operation, the staff first use multiple independently arranged connecting fan blades 32 (using axial flow fans) to direct airflow to the bottom of each energy storage battery 12. This working principle achieves precise heat dissipation for each battery unit, avoids cooling dead zones, and ensures uniform heat dissipation.

[0039] Working Principle: When this device is needed, the control unit (STM32F103) monitors the system status in real time. During the low-temperature start-up phase, when the temperature detection unit 22 (DS18B20) detects that the surface temperature of the energy storage battery 12 is lower than the set value (e.g., 5°C), the control unit outputs a signal to activate the heating pad 25 (silicone rubber heating element), which heats the battery through the heating wire 26 (nickel-chromium alloy). When the battery temperature reaches the normal operating range (e.g., 10°C), the control unit automatically shuts off the heating. During the high-temperature operation phase, when the temperature detection unit 22 detects that the battery temperature exceeds the set upper limit (e.g., 45°C), the control unit activates the drive motor 31 (DC24V brushless motor), which drives the connected fan blades 32 (axial fan) to perform forced air cooling on the bottom of the energy storage battery 12 until the temperature returns to the normal range. Through this intelligent temperature control mechanism, both the start-up performance of the battery in low-temperature environments and the operational safety under high-temperature conditions are ensured.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
