Function of BMS battery connection harness

Overview: BMS battery harness is responsible for the real-time transmission of voltage and temperature signals between battery modules. However, the use environment of the battery pack is very complex. In order to ensure the stable transmission of the BMS battery harness signal, it is required to be resistant to high temperature, high voltage, tortuosity and flexibility.

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

In new energy vehicles, BMS mainly controls the battery cells and communicates and exchanges information for the whole vehicle. When high-power equipment in the car is working, it will generate strong electromagnetic interference. The electromagnetic environment of the whole vehicle where the BMS is located is relatively complex, and it will be interfered more or less. This requires the BMS harness of new energy vehicles to have the characteristics of anti-electromagnetic interference to ensure that the data such as battery voltage and current are collected more accurately.
The BMS battery harness adopts a shielding design, which can effectively reduce the impact of EMI (electromagnetic interference) and RFIC radio interference on the vehicle system. Application scope: BMS, power battery BMS, new energy vehicles.

BMS battery can be protected by tape, bellows and other methods according to the location and structure of the wiring harness. The entire wiring harness has strict flame retardant requirements. The battery pack space is limited. When installing the wiring harness, pay attention to whether it is easy to wear and aging.
