Abstract
A current measuring system for measuring current from a conductor comprises a first and second circuit and a current measurer connected to a conductor connected to a first power source. The first circuit comprises an inverting operational amplifier, which generates a first threshold signal when current flows into the first power source. The second circuit comprises a biasing circuit and a non-inverting operational amplifier, which generates the first threshold signal at the second output when current flows out of the first power source.
Claims26
A current measuring system comprising:
- a current measurer, configured to generate an output signal upon sensing a current in a conductor connected to a first power source, the current measurer being connected to an input terminal of a first circuit and a second circuit;
- the first circuit and the second circuit comprising a first input and a second input connected to the input terminal, and a first output and a second output, respectively;
- the first output indicating, based on the first input, that the first power source is charging energy;
- the second output indicating, based on the second input, that the first power source is discharging energy;
- a controller connected to the first output and the second output, the controller being configured to:
- determine a first threshold signal, the first threshold signal being whichever one of the first or second output signal that is above a first signal threshold;
- and
- linearize the first threshold signal.
