The development process of the electrical box: hard wire type -> stamping chip type -> wire winding type (gradually eliminated by the market) -> PCB type (the predecessor of Tesla Efuse, the first generation of electrical box designed by a Fu for Tesla , after Tesla self-designed Efuse replacement) —> intelligent (such as using Mosfet, efuse, eswitch and other smart boxes Efuse).
Hard-wired electrical boxes
The hard-wired fuse box appeared with the development of vehicle electrical appliances to realize power switching and ensure vehicle safety by protecting the circuit (Figure 5). According to the use environment, experimental requirements and customer requirements and other factors can be equipped with upper and lower covers. It is necessary to install fuses and relays on the wiring harness, which is not only a burden on the wiring harness, but also a value-added point of the wiring harness
