Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment, and in particular to a convenient intelligent charging box for energy storage equipment. Background Technology

[0002] In the application of new energy storage systems, batteries are the core energy storage components, and their performance and lifespan directly affect the reliability and economy of the entire energy storage system. However, in actual operation, batteries may encounter various situations, such as a significant reduction in battery capacity after over-discharge protection shutdown, self-discharge leading to reduced battery capacity due to prolonged storage, differences in battery capacity caused by new battery expansion or replacement, and minor damage to batteries due to improper use. These problems not only reduce the usable capacity of the batteries, shorten the overall service life of the battery pack and the actual charge and discharge capacity, but also reduce economic benefits and extend the operating life of the energy storage system. To solve these problems, the faulty batteries are usually repaired by charging. However, the traditional repair process requires the installation of dedicated inverters, which are expensive, difficult to move, and inconvenient when working with different energy storage battery packs. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a convenient intelligent charging box for energy storage devices that can be easily moved and used.

[0004] To solve the above-mentioned technical problems, the present invention provides a portable intelligent charging box for energy storage devices. The portable intelligent charging box includes a box body and an intelligent charging mechanism. The intelligent charging mechanism is installed inside the box body. The box body is a cuboid structure formed by an upper box panel, a lower box panel, a front box panel, a rear box panel, and two side panels. The upper box panel has a handle, the rear box panel has a power grid interface connected to the intelligent charging mechanism, and the lower box panel has a charging interface connected to the intelligent charging mechanism. The intelligent charging mechanism includes a charger, a BMS management module, a circuit breaker, and a relay. The charger has a flat structure and is fixed to the inside of one of the side panels. The BMS management module is installed near the bottom corner of the rear side panel. The BMS management module is installed in the area inside the other side panel opposite the charger installation location. The relay is installed outside the area opposite the charger installation location. The relay is connected to the circuit between the charger and the charging interface. The circuit breaker is installed on the upper panel near the rear panel. The circuit breaker is connected to the circuit between the power grid interface and the charger and is communicatively connected to the BMS management module. The BMS management module is communicatively connected to the charger and the energy storage device via a CAN bus. The CAN bus interface connecting the BMS management module and the energy storage device is integrated with the charging interface.

[0005] In a preferred embodiment of this utility model, a cooling fan is installed on the outer side of the side plate on which the charger is installed, directly opposite the charger.

[0006] In a preferred embodiment of this utility model, the distance between the charger and the BMS management module is 4~8cm.

[0007] In a preferred embodiment of this utility model, an indicator light is also installed on the front panel. There are two indicator lights, namely a fault light and a running light.

[0008] In a preferred embodiment of this utility model, a terminal block is also provided inside the housing, and the terminal block and the relay are mounted on the same side plate.

[0009] In a preferred embodiment of this utility model, the charging interface mounting position is provided with a groove, and the depth of the groove is greater than the height of the portion of the charging interface protruding from the lower box plate.

[0010] In a preferred embodiment of this utility model, the length of the charger is no more than 30cm and the width is no more than 25cm, the length of the box is 40~50cm, and the width of the box is at least 5cm greater than the width of the charger.

[0011] The beneficial effects of this utility model are as follows: This utility model is a further optimization of existing energy storage battery charging and repair devices. By integrating each charger and BMS module into a dedicated enclosure, the BMS management module inspects the battery status and then automatically selects a repair strategy based on the inspection results, flexibly adjusting the charging current to charge and repair the battery. This ensures the battery reaches its optimal charging state, extends the overall lifespan of the battery pack, and reduces the risk of system failure. On the one hand, this provides high charging efficiency and precision, ensuring rapid battery performance recovery without manual intervention. Furthermore, it addresses the issue of inconsistent battery capacity by providing individual charging for each battery pack to achieve balanced charging. On the other hand, the various functional components are arranged in a compact, three-dimensional layout within the enclosure, making full use of the space. This results in a small size and light weight for the portable energy storage device's intelligent charging box, significantly reducing the burden of handling and carrying for customers. Compared to traditional inverter charging systems, it not only balances efficiency and flexibility during use but also significantly reduces costs. Attached Figure Description

Detailed Implementation

[0013] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0014] Please see Figures 1 to 4 The embodiments of this utility model include: A portable intelligent charging box for energy storage devices includes a box body and an intelligent charging mechanism. The intelligent charging mechanism is installed inside the box body. The box body is a cuboid structure formed by an upper box plate 3, a lower box plate 4, a front box plate 6, a rear box plate 5, and two side plates. The cuboid structure has a length of 45cm, a width of 26cm, and a thickness of 20cm. The upper box plate 3 is provided with a handle 7, the rear box plate 5 is provided with a power grid interface 9 connected to the intelligent charging mechanism, and the lower box plate 4 is provided with a charging interface 10 connected to the intelligent charging mechanism. The intelligent charging mechanism includes a charger 14, a BMS management module 15, a circuit breaker 11, and a relay 16. The charger 14 has a flat structure, with a length of approximately 35cm, a width of approximately 20cm, and a thickness of approximately 12cm. The charger 14 is fixed. The BMS management module 15 is installed on the inner side of the left side panel 1, near the bottom corner of the rear side of the left side panel 1. The BMS management module 15 is installed in the area on the inner side of the right side panel 2 opposite to the installation position of the charger 14. The relay 16 is installed outside the area opposite the installation position of the charger 14. The relay 16 is connected to the circuit between the charger 14 and the charging interface 10. The circuit breaker 11 is installed on the upper box 3 near the rear box 5. The circuit breaker 11 is connected to the circuit between the power grid interface 9 and the charger 14 and is communicatively connected to the BMS management module 15. The BMS management module 15 is communicatively connected to the charger 14 and the energy storage device via a CAN bus. The CAN bus interface connecting the BMS management module 15 and the energy storage device is integrated with the charging interface.

[0015] A cooling fan 18 is installed on the outer side of the left side plate 1 of the charger 14, directly opposite the charger 14. The cooling fan 18 can quickly draw the heat generated during charging out of the box, preventing overheating and affecting the working efficiency of the charger 14.

[0016] The distance between the charger 14 and the BMS management module 15 is 4-8 cm. In this embodiment, the actual minimum distance is 5.4 cm. Maintaining a certain distance can effectively prevent the charger 14 from affecting the operation of the BMS management module 15.

[0017] The front panel 6 is also equipped with indicator lights. There are two indicator lights: a fault light 13 and a running light 12. This allows on-site personnel to understand the charging status through the indicator lights during the charging process and to handle any faults promptly.

[0018] The enclosure also includes a terminal block 17, which is mounted on the same side panel as the relay 16. The terminal block 17 allows for easy connection of the relay 16 to the circuit.

[0019] The charging interface 10 is provided with a groove 8 at its mounting position. The depth of the groove 8 is greater than the height of the portion of the charging interface 10 that protrudes from the lower casing 4. This prevents the charging interface 10 from extending beyond the plane of the lower casing 10, thus preventing damage to the connector.

[0020] In practical applications, this invention utilizes the real-time data processing and precise logic judgment functions of the BMS management module 15 to monitor key battery parameters in real time. It also interacts with the charger 14 and the battery via a high-speed CAN bus to evaluate battery status and automatically optimize charging strategies. For batteries that have been idle for a long time and are self-discharging, the charger 14 can be controlled to first activate the battery with a small current, then gradually increase the current for regular charging, avoiding secondary damage to the battery from high current. In cases of inconsistent battery capacity, the charger 14 can be controlled to adjust the charging current based on collected data, enabling faster battery replenishment and achieving a balanced battery pack. Furthermore, in the event of an anomaly, the BMS management module 15 can immediately drive the relay 16 to actively disconnect the circuit based on the detected abnormal signal. Simultaneously, the circuit breaker 11 can automatically trip in case of overload or short circuit. These two mechanisms work together to provide both active and passive protection during the charging process, significantly improving safety.
