Significantly reduce the cost of automotive wiring harness
Modern automotive wiring harness has up to 2km of wire, more than 2000 lines and more than 350 hubs, 42V power supply system can significantly reduce the weight and cost of these car harness. In theory, the transmission of the same power, 42V system current is only one third of the 14V system, thus reducing the motor and power components of the current load, but also to the transmission of wire and power components to reduce the original loss of nearly nine And the cross-sectional area of the wire can be reduced to reduce the weight.
Voltage safe, easy to get
According to the European safety law provides that the safety of the human body within 50V, any system over 60V voltage, in the wire and the connection must have special insulation measures, which will increase the system weight and cost. Therefore, the choice of 42V voltage, is to meet the needs of energy at the same time, like the traditional 12V system, even when touched the electrode or metal body will not pose a threat to human safety. 42V voltage is the current automotive wiring harness generator output voltage of 14V 3 times, the use of 36V battery is conducive to the use of three traditional 12V lead-acid battery series conversion components.
