Description

Technical Field

[0002] In the automotive electrical system, the single-wire system means that one electrode of the battery (usually the negative electrode) is directly connected to the vehicle body, that is, connected to the vehicle body through a terminal. This connection method is called "grounding". The benefits of doing so include simplifying the circuit, saving wires, and making installation and maintenance more convenient. In addition, since electrical components do not need to be insulated from the vehicle body, this connection method is widely used in modern automotive electrical systems. According to national standards, the electrical systems of domestically produced vehicles all use the negative grounding method, which not only has less chemical corrosion to the frame and body metal, but also has less radio interference, thereby improving the efficiency and reliability of the automotive electrical system.
