Greenconn GT Series Waterproof Connectors for NEV Battery Systems
In new energy vehicles (NEVs), the power battery is not only the core energy source of the vehicle but also a critical factor influencing overall safety and system reliability. During real-world operation, battery systems typically work under high-voltage and high-current conditions while being continuously exposed to vibration, thermal shock, moisture, and dust. These conditions place very high demands on the stability of electrical connections.
Harsh Operating Conditions in NEV Battery Systems
In battery systems with high integration and high energy density, every connection point is directly related to the engineering reliability of the entire vehicle. This means that connectors used in battery systems must provide reliable performance in terms of dielectric strength, low contact resistance, high-temperature resistance, vibration resistance, and waterproof and dustproof capability.
Engineering Requirements for Connectors in NEV Battery Systems
Compared with conventional automotive electronics, NEV battery systems impose significantly more stringent engineering requirements on connectors. These requirements are mainly concentrated in two core application scenarios:
l Power Interconnects Within the Battery Pack
Connectors in this category are responsible for power transmission between battery cells or battery modules. They must maintain stable current-carrying capability, reliable electrical contact, and long-term durability under continuous operating conditions, effectively reducing risks associated with contact heating and system power loss.
l BMS Communication & Monitoring Interfaces
These connectors link the Battery Management System (BMS) with the battery pack, enabling real-time acquisition and transmission of critical parameters such as voltage, current, and temperature. Signal stability, environmental protection, and connection reliability are essential to ensuring safe and stable battery system operation.
