How to design and manufacture lithium battery cable?

Design principle of lithium battery cable

In order to ensure the performance and safety of lithium battery wiring harnesses, the design needs to follow the following principles:

1. Low resistance: Select a wire material with low resistance and a reasonable wire harness cross-sectional area to reduce energy loss during current transmission.

2. Good heat dissipation performance: Select wire materials with good heat dissipation performance, and rationally design the layout of the wiring harness to improve the heat dissipation effect of the battery pack.

3. High temperature resistance: the lithium battery will produce high temperature during the working process, so the lithium battery harness needs to have good high temperature resistance to ensure the stability and safety of the harness.

4. Safe and reliable: lithium battery wiring harness needs to have good insulation and corrosion resistance to prevent short circuit and damage during the working process.

The design and production of lithium battery wiring harness needs to be considered

1. Wire material selection: Select wire materials with good electrical conductivity and high temperature resistance, such as copper wire or aluminum wire. The cross-sectional area of the wire should be reasonably selected according to the current size and voltage drop requirements.

2. Insulation material selection: Choose insulation materials with good insulation properties and high temperature resistance, such as polyvinyl chloride (PVC), polyethylene (PE) or polytetrafluoroethylene (PTFE). The selection of insulation materials shall comply with relevant standards and requirements.

3. Wiring harness layout design: According to the electrical layout and requirements of the equipment, the layout of the wiring harness is reasonably designed to avoid crossing and interference between the wires. At the same time, taking into account the heat dissipation needs of lithium batteries, the heat dissipation channel of the wiring harness should be reasonably arranged.

4. Wiring harness fixing and protection: Wiring harness should be fixed and protected to prevent external force pulling, squeezing or damage during use. Materials such as tape, insulation tape, and sleeve can be used for fixing and protection.

5. Safety performance test: After the production is completed, it is necessary to conduct safety performance tests on the lithium battery wiring harness, such as resistance test, insulation test, voltage resistance test, etc., to ensure that the safety performance of the wiring harness meets the requirements.

In summary, the design and production of lithium battery wiring harnesses need to consider wire materials, insulation materials, wiring harnesses layout, wiring harnesses fixing and protection and other factors, and conduct safety performance tests to ensure the quality and safety performance of wiring harnesses. In this way, the normal operation and safe use of lithium battery equipment can be ensured. Get more lithium battery wiring harnesses from https://www.aichie.com.
