Frequently Asked Questions
Our harnesses incorporate UV-resistant jackets, weatherproof connectors (IP67+), and vibration-proof strain relief specifically for solar, wind, and storage systems. They’re constructed to withstand 20+ years of sunlight, salt, and temperature fluctuations that would deteriorate ordinary wiring.
Certainly. All high-voltage harnesses (up to 1000V) comply with UL 4703, IEC 62930, and other crucial standards. We incorporate dual insulation, arc-resistant materials, and full test documentation with every shipment.
When properly specified, our harnesses are designed for 25+ year service life in renewable applications. We test accelerated samples to validate performance under prolonged UV, thermal cycling, and mechanical stress.
The CCS achieves precise temperature monitoring by integrating Negative Temperature Coefficient (NTC) thermistors onto the Flexible Printed Circuit Board (FPC).
These NTC sensors are strategically positioned close to the cell connection points (like the nickel tabs/busbars).
As the cell temperature changes, the resistance value of the NTC thermistor changes accordingly.
The BMS monitors these resistance changes to determine if the temperature of each cell is within a safe operating range.
A typical CCS primarily consists of the following components:
Busbars: These are conductive bars, usually made of copper or aluminum, used to connect the positive and negative terminals of the cells for high-current transmission.
Flexible Printed Circuit Board (FPC/Flex PCB): This board carries the low-voltage signal lines and integrated sensors (like NTC thermistors) that transmit data to the BMS.
Insulation and Support Structure: This includes materials like PET insulating film, plastic frames, or blister trays, which provide mechanical support and necessary electrical isolation.
The CCS employs highly automated and robust connection technologies to ensure long-term stability:
Laser Welding: This is the most common and reliable method used to precisely weld the busbars onto the cell terminals, creating a robust electrical joint.
Thermal Lamination/Riveting: These processes are used to tightly and securely integrate the FPC, its components, the busbars, and the support structure.
Modular Design: By reducing reliance on manual handling, the CCS improves the repeatability and quality consistency of the connections, enabling it to better withstand the vibration, shock, and thermal expansion encountered during electric vehicle operation.
