We also comply with Chinese CCC standards, meeting domestic market access requirements. If you require any specific certification support, please feel free to contact us; we will provide you with customized solutions.
An energy storage connector is a high-voltage, high-current interconnect device specifically designed for battery energy storage systems. It establishes a safe and reliable power transmission channel between battery modules, battery clusters, combiner boxes, and power conversion systems, acting as the critical "blood vessels" of the energy storage system.
Energy storage systems typically operate under high voltage, high current, and complex environmental conditions. Dedicated connectors, through special design, meet stringent requirements such as low loss, high safety, environmental resistance, and ease of maintenance—qualities unmatched by ordinary industrial connectors.
Its core parameters include high rated operating voltage (typically up to 1000VDC or higher), high rated current (from tens to hundreds of amperes), extremely low contact resistance, and excellent current carrying and heat dissipation capabilities to ensure efficient transmission and reduce energy loss.
They possess high protection ratings (e.g., IP67), wide operating temperature ranges, corrosion resistance, and vibration and shock resistance. The housing is often made of flame-retardant materials (e.g., UL94 V-0) and equipped with a reliable mechanical locking mechanism to withstand harsh outdoor environments and prevent accidental detachment.
Key safety designs include "foolproof" key positions to prevent mis-insertion, high-voltage interlock circuits to cut off power before live insertion/removal, electric shock protection, and the use of a prominent orange housing as a high-voltage warning.
Products must comply with relevant electrical safety, performance, and environmental standards. For the entire energy storage system, relevant key safety certification standards include UL 9540, etc.
Widely used in various battery energy storage systems, including large-scale grid-side/generation-side energy storage power stations, industrial and commercial energy storage, residential energy storage systems, and related electric vehicle charging infrastructure.
Selection should mainly consider the system's maximum voltage and continuous current, connecting wire specifications, installation environment (protection level requirements), required locking method, and safety functions (such as whether HVIL is required). It is recommended to refer to the specific product specification sheet and consult with a professional engineer.
