Abstract
The invention relates an energy supply network for a vehicle powered by a fuel cell or by a battery. The energy supply network according to the invention is configured as an IT-network in which the consuming devices linked with the load current circuit are electrically connected with the vehicle body by a low impedance. An insulation monitoring device which consists of a measuring-bridge balancing stage and a buffer amplifier stage is connected between the load current circuit and the vehicle body.
Claims4
Energy supply network for a vehicle powered by a fuel cell or a battery, comprising:
- a load circuit configured as an IT-network, which has first and second load current circuit lines connected to supply electric current to current consuming parts of systems of said vehicle, said first load current circuit line being coupled to a potential greater than a potential of a vehicle body of said vehicle, and said second load current circuit line being coupled to a potential less than the potential of said vehicle body, wherein
- the first and second current circuit lines are coupled to the vehicle body by means of a first impedance;
- said current consuming parts connected to said load current circuit are electrically coupled to the vehicle body by means of a second impedance;
- and
- said first impedance has a high impedance value relative to said second impedance, which has a low impedance value.
