Behind the silent energy surges and intelligent dispatching of energy storage systems, precision connectors and custom wiring harnesses—like "neural networks" and "energy vasculature"—serve as the physical cornerstone ensuring every efficient and safe charge-discharge cycle.

Against the backdrop of the global energy structure accelerating its transition towards green and low-carbon development, the energy storage industry has become a core force supporting the construction of new power systems and achieving the "dual carbon" goals. According to the latest report from the National Energy Administration, China's new energy storage installed capacity has leaped to the world's first. The industry is fully transitioning from a policy-driven phase to a market-driven, value-deepening stage of high-quality development. In this context, the 8th Shenzhen International Energy Storage Industry Exhibition (CESE 2025) was successfully held at the Shenzhen Convention & Exhibition Center from November 24 to 26, 2025. With an exhibition scale exceeding 60,000 square meters, this annual grand event gathered over 800 leading enterprises and more than 50,000 professional visitors worldwide. It comprehensively showcased the latest technological achievements spanning upstream materials, core equipment, downstream system integration, and scenario applications, painting a clear development blueprint for the industry's future.

01 Trend Insight: Industrial Scaling-Up Advances, Demand for High-Reliability Connectivity Highlights

The unprecedented grand occasion of the exhibition is a vivid testament to the energy storage industry entering a golden period of development. The exhibition scope fully covers grid-side, power source-side, and user-side energy storage, spanning multiple technical routes such as lithium-ion batteries, sodium-ion batteries, flow batteries, and hydrogen energy storage. It also deeply integrates photovoltaic and charging piles to form an integrated "optical-storage-charging" ecosystem. A clear consensus has emerged: as energy storage systems rapidly iterate towards large capacity, high safety, long lifespan, and intelligence, the reliability of their underlying architecture is facing unprecedented rigorous tests.

Whether it is large-scale energy storage containers, integrated industrial and commercial energy storage cabinets, or precision battery packs, their efficient and stable operation relies on the absolute reliability of countless internal connection points. These connection points—high-performance electronic connectors and custom wiring harnesses—must be the most resilient link in the system. Operating in environments with continuous high voltage, high-frequency vibration, wide temperature fluctuations, and complex electromagnetic interference, any minor connection failure may lead to signal distortion, efficiency degradation, or even severe safety risks. Therefore, connectivity solutions with ultra-high reliability, excellent environmental adaptability, and electrical performance have evolved from basic components to key technologies related to the core competitiveness and intrinsic safety of energy storage systems.

02 Technological Resonance: JKUN's Solutions Deeply Align with Industrial Pain Points

As a technology-driven enterprise deeply rooted in the electronic connectivity field, Wenzhou JKUN Connector Co., Ltd. has always kept pace with cutting-edge industrial trends. We deeply recognize that to address the extreme working conditions of energy storage applications, connectivity technology must achieve breakthroughs in three key areas—these are the focus of our continuous R&D and innovation:

Addressing the Ultimate Challenges of High Voltage, High Current, and Harsh Environments

The upgrading of energy storage system voltage platforms places extreme demands on connectors' voltage resistance, current-carrying capacity, and arc resistance. JKUN's industrial-grade high-voltage connectors adopt special alloy contacts and high-performance insulating materials, ensuring ultra-low contact resistance and temperature rise during continuous high-power transmission. They meet the connectivity needs of critical nodes such as PCS and battery cluster connections. Meanwhile, the entire product series features a wide operating temperature range of -40℃ to 125℃, excellent vibration and impact resistance, and an IP rating of IP67 or higher. Unaffected by extreme outdoor environments such as deserts, coastal areas, and plateaus, they guarantee stable connections throughout the entire lifecycle.

Ensuring Precise Management and Zero-Loss Signal Transmission

Accurate Battery Management Systems (BMS) and Energy Management Systems (EMS) rely on precise voltage, temperature, and control signals. JKUN's high-precision, low-loss signal connectors and shielded custom wiring harnesses adopt optimized terminal designs and shielding structures, significantly reducing signal attenuation and Electromagnetic Interference (EMI). They provide a pure, stable signal path for the "sensory nerves" of BMS, ensuring the accuracy of system monitoring and the immediacy of control commands, thus safeguarding system safety and lifespan at the grassroots level.

Adapting to Highly Integrated and Customized System Designs

Energy storage products come in diverse forms—from household wall-mounted units to power station container systems—with vastly different internal spaces and wiring logics. JKUN's core advantage lies in providing deeply customized wiring harness solutions. Our engineering team can participate throughout the entire process, offering one-stop design services from connector selection, cable routing planning, electromagnetic compatibility design to protective kit configuration. Our advocated modular and compact wiring concept can significantly improve the space utilization rate inside equipment, optimize heat dissipation air ducts, and support small-batch rapid prototyping, helping customers accelerate product R&D and market launch.

03 Value Empowerment: Enhancing the Total Lifecycle Value of Energy Storage Systems with Reliable Connectivity

Based on a profound understanding of energy storage scenarios, Wenzhou JKUN is committed to going beyond single-component supply to become a partner helping customers enhance system value:

Quality as the Foundation, Certifications Building Global Trust

All products adhere to strict automotive-grade quality control standards, with key processes automated to ensure consistency. The products have obtained international authoritative certifications such as UL, CUL, and CE, with a plug-in lifespan exceeding 2,000 cycles. They have gained global market access and customer trust through unquestionable reliability.

Cost Reduction and Efficiency Improvement, Focusing on Total Cost of Ownership (TCO)

We provide not only components but also solutions designed to reduce potential system failure rates. High-reliability connections reduce maintenance frequency, while optimized wiring harness designs improve installation efficiency, thereby helping customers lower the total lifecycle cost of energy storage systems from installation, operation to maintenance.

Cross-Border Technology Integration, Expanding Ecological Applications

Our technical capabilities are rooted in profound experience across multiple fields such as consumer electronics, smart homes, and new energy vehicles. This cross-border perspective enables us to innovatively apply connectivity technologies, material processes, and design concepts validated in different industries to energy storage scenarios, providing customers with unique value that is more forward-looking and reliable.

04 Embarking on a "Core" Journey: Becoming a Trusted Connectivity Partner in the Energy Storage Era

The brilliance of CESE 2025 has come to an end, but the magnificent journey of the energy storage industry has just begun. At the core of the energy revolution, stable, efficient, and intelligent energy connectivity is a prerequisite for unlocking all innovative value.

Wenzhou JKUN Connector Co., Ltd. is not only a manufacturer of electronic connectors, LED connectors, and custom wiring harnesses but also a reliable professional partner you can depend on when building long-term product competitiveness and ensuring intrinsic system safety amid the rapid development of the energy storage industry. With solid craftsmanship, a commitment to quality, and a deep understanding of scenarios, we build a reliable connection bridge for every kilowatt-hour of green energy—from "cell" to "power grid".

We sincerely invite global energy storage system integrators, battery manufacturers, PCS/BMS equipment suppliers, and peers in the new energy field to cooperate.
