Ground distribution
Considering the installation position of the electrical components in the whole vehicle, and combining the load type of the electrical components and the specific grounding category, the grounding distribution design of each electrical component is carried out.
General principles ● Ground the nearest rail. Shorten the length of the ground loop as much as possible to reduce the loop voltage drop, cost and quality. ● Minimize unnecessary mutual interference between subsystems. The principle of interference generation Ideally, each electrical device needs to be grounded separately nearby. However, this will result in too many groundings in the whole vehicle, which will greatly increase the complexity of assembly, and increase the quality and cost of the entire vehicle. Therefore, this method does not Not the best choice. When setting the ground, it must be considered to share and combine the ground.
