The role of the battery BMS connection cable

The full English name of BMS is Battery Management System, and the Chinese name is battery management system. Its main function is to detect battery status, manage vehicle power batteries, enhance battery usage efficiency, and avoid battery life due to excessive charging and discharging. One of the important components of the BMS system is the BMS battery harness, which plays a signal transmission role between the system components.

The BMS battery harness is responsible for the real-time transmission of voltage and temperature signals between battery modules. However, the usage environment of battery packs is very complex. To ensure the stable transmission of BMS battery wiring harness signals, it requires high temperature resistance, high voltage resistance, bending resistance and flexibility.

In new energy vehicles, BMS mainly controls the battery cells, communicates and exchanges information with the entire vehicle. When high-power equipment in the car is working, strong electromagnetic interference will be generated. The electromagnetic environment of the entire vehicle in which the BMS is located is relatively complex and will be more or less subject to interference. This requires the BMS wiring harness of new energy vehicles to have anti-electromagnetic interference characteristics to ensure the collection of batteries. Data such as voltage and current are more accurate.

The BMS battery wiring harness adopts a shielding design, which can effectively reduce the impact of EMI (electromagnetic interference) and RFIC radio interference on vehicle systems. Application scope: BMS, power battery BMS, new energy vehicles.

Depending on the location and structure of the wiring harness, BMS batteries can use protective methods such as tape and corrugated tubes. The entire wiring harness has strict flame retardant requirements. The battery pack space is limited, so when installing the wiring harness, pay attention to whether it is prone to wear and aging.
