Abstract
The invention relates to a device for measuring an electric current between a vehicle battery and an electrical consumer connected to the vehicle battery. The claimed device includes a bus bar which picks up the electric current in the vehicle battery and guides it further to the electrical consumer, on which a first current sensor and a second current sensor which is different from the first current sensor are arranged, the current sensors being designed to measure, independently from each other, the electric current circulating in the bus bar.
Claims10
A device for measuring an electric current between a vehicle battery and an electrical consumer connected to the vehicle battery, said device comprising a busbar, which receives the electric current from the vehicle battery and transfers it to the electrical consumer and on which a first current sensor and a second current sensor, which is different from the first current sensor, are arranged, said current sensors being configured to measure the electric current through the busbar independently of one another.
A vehicle battery comprising:
- an electrical connection for outputting an electric current to an electrical consumer or, respectively, for receiving an electric current from an electrical energy source, and
- a device for measuring an electric current between a vehicle battery and an electrical consumer connected to the vehicle battery, said device comprising a busbar, which receives the electric current from the vehicle battery and transfers it to the electrical consumer and on which a first current sensor and a second current sensor, which is different from the first current sensor, are arranged, said current sensors being configured to measure the electric current through the busbar independently of one another, said device being connected to the electrical connection.
A method for detecting a measured value for an electric current between a vehicle battery and an electrical consumer connected to the vehicle battery, said method comprising:
- detecting a first value for the electric current using a first current sensor,
- detecting a second value for the electric current using a second current sensor, which is different from the first current sensor, and
- determining the measured value for the electric current on the basis of the first and second value.
A control device, which is designed to perform a method for detecting a measured value for an electric current between a vehicle battery and an electrical consumer connected to the vehicle battery, said method comprising:
- detecting a first value for the electric current using a first current sensor,
- detecting a second value for the electric current using a second current sensor, which is different from the first current sensor, and
- determining the measured value for the electric current on the basis of the first and second value.
