[0002] As the core carrier of modular energy storage systems, energy storage containers contain complex power electronic devices (such as PCS and BMS) and a large number of communication harnesses (CAN bus, RS485, Ethernet, etc.). These harnesses are responsible for transmitting signals for battery status monitoring, system control, and safety protection. Their reliability directly affects the operational safety of the entire energy storage system.

[0003] The following key issues exist in the protection of communication harnesses in existing energy storage containers: (1) mechanical damage risk: frequent vibrations during container transportation and operation, traditional corrugated pipes or open wiring can easily lead to harness wear; (2) electromagnetic interference: when high-voltage power cables and communication lines run parallel to each other, coupling interference can lead to an increase in the error rate of BMS signals; (3) maintenance cost: long-term exposure of harnesses to the outside can easily increase maintenance costs.

[0004] To address the aforementioned technical issues, it is essential to design a sodium-electric energy storage communication harness protection mechanism. Utility Model Content

[0020] Please see Figures 1-4 A sodium-ion battery energy storage communication harness protection mechanism includes a U-shaped protective groove 1, the surface of which is coated with a corrosion-resistant layer 2. U-shaped holes 3 are formed on the surface of the U-shaped protective groove 1. A baffle 4 is located below the U-shaped protective groove 1, and a harness outlet 7 is formed on the surface of the baffle 4. By setting up the U-shaped protective groove 1, the corrosion-resistant layer 2, and the U-shaped holes 3, the harness can be arranged in the U-shaped protective groove 1, providing physical protection for the communication harness. This prevents the harness from being damaged by collisions, compression, or mechanical damage from external objects during container transportation and operation, ensuring the integrity of the harness and preventing damage to the cable or other cables from external environmental factors such as water, fire, and corrosion. Damage to wires can be prevented, ensuring the normal use and safety of cables or wires. This also reduces the cost of cable or wire repair and replacement, improving production efficiency and economic benefits. It enhances the aesthetics and durability of the wires, making them safer, more reliable, and more durable. The corrosion-resistant layer 2 effectively resists corrosive substances in the external environment, such as moisture and chemical gases, extending the service life of the protective groove and reducing the risk of damage caused by corrosion, thus better protecting the internal communication harness. The harness outlet 7 facilitates the exit of the communication harness from the protective mechanism for connection to external equipment, making the harness layout more organized and convenient for installation and maintenance.

[0021] Please see Figure 1 Both sides of the U-shaped protective groove 1 are provided with L-shaped mounting plates 5. The surface of the L-shaped mounting plates 5 is provided with mounting holes 6. By setting the L-shaped mounting plates 5 and mounting holes 6, the communication harness protection mechanism can be conveniently and securely installed in a suitable position inside the energy storage container. The anti-loosening buckle structure passes through the mounting holes 6 to firmly fix the protection mechanism, ensuring that it will not loosen or shift under container vibration, and ensuring continuous and effective protection of the communication harness.

[0022] Please see Figure 1 The thickness of baffle 4 is 0.5mm, and the surface is treated with rust prevention. The material of baffle 4 is carbon steel. By setting baffle 4, a certain strength is ensured, which can provide reliable protection for the wire harness. The rust prevention treatment can prevent baffle 4 from rusting and corroding in humid environments, extend the service life of baffle 4, and ensure the long-term effectiveness of its protective function.

[0023] Please see Figure 2 The U-shaped protective groove 1 has a support plate 8 inside, and a semi-circular groove 9 is formed on the surface of the support plate 8. By setting the support plate 8 and the semi-circular groove 9, the communication wire harness placed in the U-shaped protective groove 1 can be supported and fixed. The shape of the semi-circular groove 9 is adapted to the shape of the wire harness, which can make the wire harness be placed stably in the groove, prevent the wire harness from shaking in the protective groove, reduce wear caused by friction between the wire harness and the inner wall of the protective groove, and further improve the reliability and service life of the wire harness.

[0024] Please see Figure 2 The inner wall of the U-shaped protective groove 1 is provided with a sliding groove 10. A slider 11 is fixedly connected to the surface of the support plate 8. The side of the slider 11 away from the support plate 8 extends into the inner cavity of the sliding groove 10 and is movably connected to the sliding groove 10. Through the cooperation of the sliding groove 10 and the slider 11, the support plate 8 can be movably installed in the U-shaped protective groove 1, so that the position of the support plate 8 can be flexibly adjusted according to actual needs, which is convenient for supporting and protecting different positions of the wire harness.

[0025] Please see Figures 1-3 A cover plate 14 is fitted onto the surface of the U-shaped protective groove 1, and a slot 12 is formed on the surface of the U-shaped protective groove 1. A flexible retaining strip 13 is fixedly connected to the inner wall of the cover plate 14, and one side of the flexible retaining strip 13 extends into the inner cavity of the slot 12. By setting the cover plate 14, more comprehensive protection can be provided for the internal communication harness, preventing dust and debris from entering the protective groove, keeping the harness clean, and reducing the risk of short circuits and other faults caused by dust accumulation. By setting the slot 12 and the flexible retaining strip 13, the cover plate 14 and the U-shaped protective groove 1 are connected. The connection method is convenient and quick, and also has a certain degree of sealing. The flexible retaining strip 13 can fill the slot 12, enhancing the sealing effect at the connection. At the same time, its elasticity also makes the installation and removal of the cover plate 14 relatively easy, which facilitates the inspection and maintenance of the harness in the protective groove.

[0026] In use, the sodium battery energy storage communication harness protection mechanism is applied to a sodium battery energy storage container. The communication harness includes CAN bus, RS485 and Ethernet cables, with a total length of approximately 200 meters. The container must meet the marine vibration standard IEC60068-2-6 and the outdoor IP55 protection level requirements. The U-shaped protection channel 1 is made of Q-235-A steel, which is laser-cut and then bent into shape. The surface is treated with electrostatic powder coating to form an 80μm thick epoxy coating. The overall length of the U-shaped protection channel 1 is 2.68 meters. After welding, it is ground to a roughness of Ra2.8μm. The U-shaped protection channel 1 runs along the front of the container and is fixed at the top with M6 stainless steel bolts. It has the function of isolating vibration and mechanical damage. The baffle 4 is made of Q235-A carbon steel with a thickness of 0.5mm. After phosphating treatment, it is coated with fire-retardant paint with a fire resistance limit of 1 hour. The baffle 4 is installed at the bottom of the container and fixed with M4 quick-release bolts. The baffle 4 is grounded as a whole, with a grounding resistance of ≤0.1Ω, to further reduce electromagnetic interference.

[0027] In simulated transportation vibration tests, baffle 4 reduced the harness amplitude by 70%, and the BMS signal bit error rate decreased from 10. -4 Reduced to 10 -6The U-shaped protective groove 1 uses an anti-loosening snap-fit ​​structure at the plug-in point, which reduces the wire harness replacement time from the traditional 2 hours to 20 minutes. The plug-in terminals are tin-plated, with a contact resistance of ≤5mΩ. The CAN bus signal attenuation test shows that the shielding effectiveness is ≥60dB at 20MHz. After operating for 6 months in an environment with 85% humidity and salt spray, the U-shaped protective groove 1 showed no rust and the coating did not peel off. The wire harness still maintained its flexibility at a low temperature of -30℃ and no sheath cracking occurred. The initial cost increased by 15%, but the maintenance cost decreased by 80%, and the total life cycle cost decreased by 40%. The modular design improved the container assembly efficiency by 35%.

[0028] In summary, this sodium-ion energy storage communication harness protection mechanism, by setting up a U-shaped protective groove 1, a corrosion-resistant layer 2, and a U-shaped hole 3, solves the problems of existing energy storage containers lacking a protective structure for their communication harnesses, open wiring easily leading to harness wear, and long-term exposure of the harness to the outside easily increasing maintenance costs.
