As an important component of lithium batteries, battery wiring harness plays a key role in improving battery performance. Let's discuss with you the function and design principles of lithium battery wiring harness.   The role of lithium battery wiring harness( OEM Wire Harness Overall Solution Elbow Power Cord,Custom Wire Harness EC5-F/M UL Male And Female,Unipolar 45A Plug Sheathed Soft Silicone Wire) The lithium battery wiring harness is a combination of wires that connect the battery cells. Its main function is to provide current transmission and battery management system functions. Lithium battery wiring harness plays a vital role in improving battery performance, including the following aspects: 1. Current transmission: The lithium battery harness transmits current from the battery core to the entire battery pack by connecting the battery cells to ensure the normal operation of the battery pack. At the same time, lithium battery harnesses need to have low resistance and high conductivity to reduce energy loss during current transmission. 2. Temperature control: Lithium batteries generate heat when working, and the lithium battery harness needs to have good heat dissipation performance to ensure that the temperature of the battery pack is within a safe range. Through reasonable wire harness design and material selection, the heat dissipation effect of the battery pack can be improved and the service life of the battery can be extended.   3. Battery management system support: The lithium battery harness also needs to be connected to the battery management system (BMS) to monitor and manage the battery pack. Through the connection between the lithium battery harness and the BMS, the voltage, temperature, current and other parameters of the battery pack can be monitored in real time to ensure the safety performance of the battery pack. Lithium battery wiring harness design principle In order to ensure the performance and safety of lithium battery wiring harness, the following principles need to be followed during design: 1. Low resistance: Choose low-resistance wires and a reasonable wire harness cross-sectional area to reduce energy loss during current transmission.   2. Good heat dissipation performance: Select wires with good heat dissipation performance and rationally design the wiring harness layout to improve the heat dissipation effect of the battery pack.   3. High temperature resistance: Lithium batteries will generate high temperatures when working, so the lithium battery wiring harness needs to have good high temperature resistance to ensure the stability and safety of the wiring harness.   4. Safe and reliable: Lithium battery wiring harness needs to have good insulation performance and corrosion resistance to prevent short circuit and wiring harness damage during work.
