Abstract
The invention relates to a measuring transducer for charging stations of electric vehicles. In the measuring transducer, a measuring device is connected to a direct current charging circuit for detecting at least one direct current measurement variable. A transducer for converting the direct current measurement variable into an alternating current actuating variable is provided, and the measuring transducer also includes an actuating means for adjusting at least one alternating current variable in an alternating current measuring circuit as a function of the alternating current actuating variable.
Claims16
A measuring transducer for charging stations of electric vehicles comprising:
- a measuring device that can be connected to a direct current charging circuit for detecting at least one direct current measurement variable;
- a transducer for converting the direct current measurement variable into an alternating current measurement variable;
- an actuating means for adjusting at least one alternating current variable in an alternating current circuit as a function of the alternating current actuating variable;
- wherein the alternating current circuit is an alternating current measuring circuit with alternating current measuring technology and wherein the active power in the alternating current measuring circuit is less by a constant factor than the power in the direct current charging circuit.
A method for operating a measuring transducer, in particular according to one of the above claims, comprising the steps of:
- measuring, in a direct current charging circuit, at least one direct current measurement variable;
- determining from the direct current measurement variable an alternating current actuating variable;
- and
- operating an alternating current circuit with an alternating current variable as a function of the alternating current actuating variable;
- wherein the alternating current circuit is an alternating current measuring circuit with alternating current measuring technology and wherein the active power in the alternating current measuring circuit is less by a constant factor than the power in the direct current charging circuit.
