[0023] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0024] Example 1

[0025] This embodiment provides an integrated battery system, which includes: a packaging box 100, a power storage component 200 and a control component 300. The packaging box 100 is provided with a placement cavity and a control cavity. The power storage component 200 is arranged in the placement cavity, and the control component 300 is arranged in the control cavity. A connector interface 400 for connecting to an external electrical appliance is provided on the packaging box 100, and the control component 300 is electrically connected to the power storage component 200 and the connector interface 400 respectively.

[0026] Please refer to Figure 1 and Figure 2As shown, in this embodiment, the packaging box 100 is a hollow box structure, in which the power storage component 200 and the control component 300 are placed. In addition to encapsulating and protecting the internal power storage component 200 and the control component 300, the packaging box 100 can also form a fixed frame for fixing and placing the power storage component 200 and the control component 300 to ensure the stability of the power storage component 200 and the control component 300. The power storage component 200 and the control component 300 are respectively placed and fixed in the placement cavity and the control cavity in the packaging box 100, and are placed and fixed separately to facilitate later replacement and maintenance. After installation, the power storage component 200 and the control component 300 form an integral structure with the packaging box. The packaging box is provided with a connector interface 400 with the control component 300, and the external electrical equipment is connected through the connector interface 400. After the power storage component 200 and the control component 300 are encapsulated, on the one hand, they can make full use of the space, reduce the volume of the entire battery system, and facilitate installation. During installation, simply attach and secure the packaging box 100 to the vehicle, making it easy to operate. Furthermore, the integration of the control assembly 300 and the power storage assembly 200 significantly reduces the number of cables connecting the power storage assembly 200 and the control assembly 300, reducing costs while also preventing exposed cables from causing damage or electric shock, thereby ensuring the safety and service life of the battery system.

[0027] Optionally, in some implementations of this embodiment, the control component 300 includes battery management control devices such as module connectors, branch short-circuit protection devices, charging circuits, electric drive pre-charging circuits, current detection sensors, auxiliary drive pre-charging circuits, manual maintenance switches, BMS control modules, BMS high-voltage acquisition insulation modules, DC / DC controllers, domain controllers, high-voltage integrated components, and low-voltage connectors. The above-mentioned control component 300 is an existing battery management control structure. The types of specific control devices and control circuits are not limited here and can be added or reduced according to actual functional requirements. All control devices are arranged inside the packaging box 100 and form circuit connections. The power storage component 200 is connected to the control component 300 by copper busbar bolts and other methods, which reduces connecting cables, increases reliability and safety, and the control component 300 does not need a bracket to be fixed to the vehicle separately, thereby improving the utilization of space of the entire vehicle.

[0028] Optionally, in some embodiments of this embodiment, the integrated battery system further includes a temperature detection device and a cooling assembly, the temperature detection device and the cooling assembly are electrically connected to the control assembly 300, the cooling assembly is arranged inside the packaging box 100, and the control assembly 300 adjusts the temperature in the placement cavity based on the detected temperature of the temperature detection device and controls the cooling assembly.

[0029] Please refer to Figure 1 and Figure 2As shown, in this embodiment, the temperature detection device can be a temperature sensor, which is used to detect the temperature inside the packaging box 100. The control component 300 determines the temperature inside the packaging box 100 and the temperature of the power storage component 200 based on the temperature information detected by the temperature detection device. A cooling component is also provided inside the packaging box 100. The cooling component is electrically connected to the control component 300. The control component 300 controls the cooling component to work based on the temperature information detected by the temperature detection device, thereby cooling the inside of the packaging box 100 and cooling the power storage component 200, ensuring the temperature stability of the battery system, improving the service life of the battery system, and avoiding safety accidents. It can be understood that the power storage component 200 and the control component 300 may emit heat during the charging and discharging process, causing the temperature inside the packaging box 100 to rise. Since the packaging box 100 integrates the power storage component 200 and the control component 300, and the arrangement is relatively concentrated, the heat dissipation effect is not ideal. The temperature inside the packaging box 100 may rise above a threshold, affecting the normal use of the battery system. In severe cases, it may damage the power storage component 200 or the control component 300, leading to a safety accident. Therefore, by providing a cooling component within the packaging box 100, the temperature inside the packaging box 100 is controlled, ensuring that the internal environment of the packaging box 100 and the temperature of the power storage component 200 are relatively stable, thereby improving the service life and safety of the battery system.

[0030] Optionally, in some implementations of this embodiment, the cooling assembly includes a liquid cooling plate 500 and a heat exchange device, the liquid cooling plate 500 is arranged in the placement cavity, and the liquid cooling plate 500 is connected to the heat exchange device pipeline, and the heat exchange device is electrically connected to the control assembly 300.

[0031] Please refer to Figure 3 As shown, in this embodiment, the cooling assembly includes a liquid cooling plate 500 and a heat exchange device. The number of liquid cooling plates 500 can be one or more. The liquid cooling plate 500 is placed in contact with the power supply assembly to cool the power storage assembly 200. A liquid pipeline is provided inside the liquid cooling plate 500. The liquid cooling plate 500 is connected to the heat exchange device through the liquid pipeline. The coolant in the liquid cooling plate 500 flows through the heat exchange device and exchanges heat with the external environment for cooling. The cooled liquid then flows back to the liquid cooling plate 500 to cool the power storage assembly 200. The liquid cooling plate 500 and the heat exchange device form a circulating liquid cooling loop, achieving a cooling effect on the interior of the packaging box 100.

[0032] Optionally, in some implementations of this embodiment, the power storage assembly 200 includes a plurality of battery modules 201 arranged at intervals, and a liquid cooling plate 500 is provided between two adjacent battery modules 201 .

[0033] Please refer to Figure 3As shown in this embodiment, a plurality of battery modules 201 are arranged in the packaging box 100, and the plurality of battery modules 201 are connected in series or in parallel to form a power storage assembly 200. It should be noted that, Figure 3 The battery modules 201 are shown as being arranged vertically to form a multi-layer structure. This is only one arrangement of the battery modules 201. In other embodiments, the battery modules 201 can also be arranged vertically to form a multi-row or multi-column structure. The arrangement of the battery modules 201 is not limited. At the same time, the number of battery modules 201 can be adjusted according to the size of the packaging box 100 and the actual amount of power to be stored. The specific number can be three, four, five, or six, etc. There is no limit. Multiple battery modules 201 are arranged at intervals, and a heat dissipation gap is formed between two adjacent battery modules 201. The liquid cooling plate 500 of the cooling assembly is arranged between two adjacent battery modules 201 to cool the battery modules 201.

[0034] Optionally, in some implementations of this embodiment, the control component 300 includes a control valve provided at a liquid inlet or a liquid outlet of the liquid cooling plate 500 , and the control valve is used to control the temperature control effect of the liquid cooling plate 500 .

[0035] In this embodiment, the control valve can be a 24V solenoid control valve, which is used to control the flow of coolant flowing through the liquid cooling plate 500, thereby controlling the cooling effect of the liquid cooling plate 500. It can be understood that when the flow of coolant in the liquid cooling plate 500 is increased, the cooling effect of the liquid cooling plate 500 can be improved, and the temperature of the battery module 201 can be quickly reduced, but energy consumption will increase. Conversely, when the flow of coolant is reduced, the cooling effect is reduced, but energy is saved. The control component 300 adjusts the opening amount of the control valve in real time based on the temperature results detected by the file detection device, ensuring the cooling effect while saving energy. In this embodiment, when multiple liquid cooling plates 500 are provided, an independent control valve is provided at the liquid inlet or outlet of each cooling plate. The control component 300 can independently control each control valve, thereby independently controlling the operating state of each liquid cooling plate 500, reducing power consumption and temperature, and improving the safety and service life of the battery system.

[0036] Optionally, in some implementations of this embodiment, a sliding guide rail 600 is provided in the placement cavity, and the liquid cooling plate 500 is slidably provided on the sliding guide rail 600 .

[0037] In this embodiment, the liquid cooling plates 500 slide onto the slide rails 600, facilitating assembly and disassembly and maintenance. The multiple layers of liquid cooling plates 500 are independent of each other, each layer being individually positioned via a control valve. This allows for individual liquid cooling plates 500 to be inspected and replaced during maintenance and replacement, improving practicality.

[0038] Optionally, in some implementations of this embodiment, an inspection port corresponding to the position of the liquid cooling plate 500 is opened on the packaging box 100 .

[0039] In this embodiment, the liquid cooling plate 500 is slidably disposed in the placement cavity, and the liquid cooling plate 500 can be pushed by sliding, so that the liquid cooling plate 500 can be taken out from the inspection port or placed into the interior of the packaging box 100 from the inspection port, thereby improving the convenience during operation. There is no need to disassemble other components such as the battery module 201, and disassembly and maintenance are convenient.

[0040] Optionally, in some implementations of this embodiment, an explosion-proof valve 501 is provided on the liquid cooling plate 500 , and the explosion-proof valve 501 is connected to a liquid pipeline inside the liquid cooling plate 500 .

[0041] In this embodiment, the liquid outlet of the explosion-proof valve 501 is arranged on the outside of the packaging box 100. When the liquid pressure inside the liquid cooling plate 500 exceeds the threshold value, the explosion-proof valve 501 opens, and the liquid is discharged from the explosion-proof valve 501 out of the packaging box 100, thereby reducing the pressure of the liquid pipeline in the liquid cooling plate 500, avoiding the liquid pipeline of the liquid cooling plate 500 from bursting, causing the liquid to flow into the interior of the packaging box 100 and causing damage to the circuit of the battery module 201 or the control component 300, thereby improving the safety of the battery system.

[0042] Optionally, in some implementations of this embodiment, a safety protection component is provided in the packaging box 100 , and the safety protection component includes a smoke detector 700 and a fire extinguishing device, and both the smoke detector 700 and the fire extinguishing device are electrically connected to the control component 300 .

[0043] Please refer to Figure 1 As shown, in this embodiment, the safety protection component includes a smoke detector 700 for detecting whether there is a fire inside the packaging box 100 and a fire extinguishing device for extinguishing the fire. It can be understood that the chemical substances in the existing battery module 201 are prone to spontaneous combustion when leaked. When a battery fire occurs, the smoke detector 700 detects the relevant signal, and the control component 300 promptly controls the fire extinguishing device to extinguish the fire source in time, ensuring the safety of the entire battery system. Because the control component 300 and the power storage component 200 are installed together, and a relatively closed environment is formed within the packaging box 100, the smoke detection component can quickly and promptly detect the fire signal, ensuring the timeliness of fire extinguishing.

[0044] Optionally, in some implementations of this embodiment, the fire extinguishing device may be an aerogel fire extinguisher. Among fire extinguishers with comparable fire extinguishing performance, aerosol fire extinguishers offer advantages such as the smallest size, longest effective spray time, widest operating temperature range, highest safety, and pressure-free storage and maintenance-free operation. They are particularly suitable for protecting electronic equipment, live equipment, and locations prone to gas fires. Because the product is pressure-free, there are no annual inspection fees or reagent replacement costs for the extinguisher, and the product has no maintenance costs during its four-year validity period.

[0045] Optionally, in some implementations of this embodiment, an outer side wall of the packaging box 100 is provided with a mounting beam 800 , and the mounting beam 800 can be fixedly connected to the frame of the vehicle.

[0046] Please refer to Figure 1 As shown, in this embodiment, fixing holes are provided on the packaging box 100 and the mounting beam 800, and the mounting beam 800 is fixed to the packaging box 100 by fixing bolts or rivets. The packaging box 100 is connected to the external vehicle body through the mounting beam 800, thereby fixing the entire battery system to the vehicle and ensuring the stability of the battery system.

[0047] The mounting beam 800 is detachably connected to the packaging box 100 , and different mounting beams 800 can be replaced as needed, making it easier to install the packaging box 100 on vehicle frames of different models, thereby improving the practicality of the battery system.

[0048] In summary, the present invention provides an integrated battery system, which includes: a packaging box 100, a power storage component 200 and a control component 300, the packaging box 100 is provided with a placement cavity and a control cavity, the power storage component 200 is arranged in the placement cavity, the control component 300 is arranged in the control cavity, the packaging box 100 is provided with a connector interface 400 for connecting an external electrical appliance, and the control component 300 is electrically connected to the power storage component 200 and the connector interface 400 respectively. The power storage component 200 and various components such as the transformer and the control module are assembled and installed into a whole through the packaging box 100, which is convenient for subsequent installation and reduces the installation space occupied by the battery system. At the same time, after integration, the cables connecting the power storage component 200 and the control component 300 can be effectively reduced, effectively reducing costs and the occurrence of accidents such as cable damage and loose connection points, thereby improving the safety of the battery system during use.
