Mehrspannungsbordnetz

摘要

The invention relates to a multi-voltage wiring loom with at least two voltages different from earth of e.g. 14V and 24V. One of the voltages is generated by e.g. the alternator of a vehicle and the other voltage generated from the first by means of a d.c.-converter. The two voltages supply two separate d.c. circuits. To protect against short circuit between the two voltages, means are provided to extensively reduce short circuits and/or reduce the effects of a short circuit between the two voltages and/or protect or switch off loads at risk in case of a short circuit. In addition, for protection against short-circuit in the multi-voltage wiring loom, a combined system for electrical battery and energy management can be fitted.
