Energy Storage System

Liquid-Cooled Quick Connectors for Energy Storage Systems

Developed for container-based, commercial and industrial, and residential energy storage applications

Ensures leak-free connections throughout the entire lifecycle, from 1500V high voltage to extreme cold of -40°C

Uneven temperature rise in the battery pack during operation leads to reduced cell consistency and a decrease in lifespan.
Space inside the energy storage container is limited, and the battery modules require frequent removal and reinsertion for maintenance.
Outdoor environments are harsh (salt fog, extreme cold, high temperatures), making seals prone to aging and leakage.
High-voltage systems (1500 V DC) are extremely sensitive to fluid leaks, which can cause short circuits and fires.
The skill levels of operations and maintenance personnel vary, and there are potential hazards associated with incorrect insertion or removal of cables, or cables that are not fully seated.
The battery system has a service life of 10–15 years; the connectors must have the same service life and be maintenance-free.

High-efficiency, uniform heat dissipation: The liquid-cooled plate and quick-connect fittings form a low-resistance circuit, keeping the temperature difference between clusters within 2°C and extending the system’s service life.
Blind-mate floating design: Supports position compensation of ±2 mm to ±4 mm; the battery module automatically aligns and connects when pushed in, eliminating the need for manual locking of the tubing.
Wide Temperature Range: Operating temperature range of -40°C to 105°C, IP67 protection rating, and salt spray test of ≥720 hours; suitable for coastal and desert power plants.
Dual-redundant sealing: primary seal + secondary safety seal; leak-free for ≥2,000 insertion/removal cycles; instantaneous shut-off at both ends upon disconnection.
Anti-misinsertion design: Connectors of different sizes feature mechanical misinsertion prevention (color-coded or otherwise) and provide tactile and audible feedback when properly seated to ensure a secure connection.
Long-Life Validation: Designed for a service life of ≥15 years, as verified through accelerated life testing, including thermal aging, thermal shock, vibration, and corrosion tests.
