Driven by the dual carbon strategy, the energy storage industry has witnessed explosive growth.From residential solar-storage integration systems and industrial & commercial energy storage containers to large-scale grid energy storage power stations, energy storage equipment has become a critical support for new energy accommodation and power grid peak shaving.
What is less known is that behind core components such as battery cells, inverters, and BMS, connectors serve as the "bridge" for energy and signal transmission.They directly determine the safety, stability, and full-life-cycle operation and maintenance costs of energy storage systems, acting as the "invisible cornerstone" supporting the long-term reliable operation of energy storage equipment.
The operating conditions of energy storage equipment impose far more stringent requirements on connectors than ordinary electronic components.Unlike the mild operating environment of consumer electronics, energy storage systems must withstand long-term high voltage and high current shocks, while outdoor deployments face tests including rain, snow, dust, and extreme temperature differences.
Choosing the right manufacturer and brand is especially critical when it comes to professional connectors.Founded in 2002, Changzhou Amass Electronics Co., Ltd. (the original creator of the XT Series) has 24 years of expertise in DC high-current connectors for low-voltage intelligent equipment below automotive grade.We are a national-level Specialized, Sophisticated, Unique, and New "Little Giant" enterprise and a high-tech enterprise integrating design, R&D, manufacturing, and sales.
We have more than 200 patents, over 10,000 project cases, and have supplied customers with a cumulative installed volume exceeding 100 million units.
Located in Lijia Industrial Park, Wujin District, Jiangsu Province, our company covers a production area of over 30,000 square meters with independent land property rights. We have a team of nearly 300 professionals dedicated to R&D, manufacturing and sales.
We offer more than 100 types of connectors to meet the demands of various applications, including garden tools, energy storage equipment, electric vehicles, smart home appliances, intelligent robots, as well as aircraft models and drones. Meanwhile, we provide efficient product development and production services, delivering full-lifecycle 7A solutions for industrial customers.
High-safety protection design builds the first line of defense for energy storage operation.Premium energy storage connectors must combine high-voltage insulation and environmental durability. Featuring UL94 V0 flame-retardant housing and dual sealing structure, they achieve an IP67 or higher protection rating, effectively resisting rain, snow and dust intrusion in outdoor environments and eliminating short-circuit risks caused by moisture.
Meanwhile, the anti-misinsertion design reliably prevents reverse polarity of positive and negative electrodes.With excellent current-carrying capacity and low-loss characteristics, they help energy storage systems reduce costs and improve efficiency.
During the charging and discharging process of energy storage systems, connectors must carry continuous high-power current.High-quality products use high-conductivity copper alloy contacts with special plating treatment, limiting contact resistance to below 0.5 mΩ and temperature rise to less than 30 K under rated current for 4 hours, greatly reducing power loss.
Full-scenario adaptability to meet the diverse application demands of energy storage.Connector specifications vary significantly across different energy storage scenarios: residential energy storage prioritizes compact size and easy installation, supporting various current ratings.
In addition, the wide operating temperature range (from -40°C to 120°C) enables adaptation to extreme climates in different regions,meeting the requirements of complex environments such as coastal salt spray and severe cold in northwest China.
In practical applications, high-quality connectors have become the key to cost reduction and efficiency improvement in energy storage projects.
As energy storage technology upgrades toward higher integration and intelligence, connectors are embracing new development opportunities.
Smart connectors integrated with temperature and current sensors can provide real‑time operating status feedback and predict potential failures in advance.The integrated design, combining cooling tubes and signal monitoring modules, further reduces size and improves system integration efficiency.
Meanwhile, products compliant with international environmental standards such as RoHS2.0 and REACH also remove trade barriers for energy storage equipment exports.
The high-quality development of the energy storage industry relies on the quality commitment of core components.Although connectors are small in size and account for a low proportion of procurement costs, they undertake the core mission of ensuring the safe operation of energy storage systems.
At a time when the industry is transforming from "rapid expansion" to "quality competition", high-quality connectors — with their high safety, high reliability and high adaptability — are helping energy storage equipment break through technical bottlenecks and laying a solid micro-foundation for the sustainable development of the new energy industry.
