Abstract
An aftertreatment system of a vehicle includes an electric heater device; a converter structured to provide power to the electric heater device; and a monitoring system including: a current measuring device structured to measure an input current at an input terminal of the converter; and a controller structured to determine an output current at an output terminal of the converter based at least on the input current measured at the input terminal and an operation condition of the converter.
Claims13
An aftertreatment system for a vehicle, comprising:
- an electric heater device;
- a converter structured to provide power to the electric heater device;
- and
- a monitoring system including:
- a first voltage measuring device structured to measure an input voltage at an input terminal of the converter;
- a second voltage measuring device structured to measure an output voltage at an output terminal of the converter;
- a current measuring device structured to measure an input current at the input terminal;
- and
- a controller structured to determine an output current at the output terminal based on the input voltage measured at the input terminal, the input current measured at the input terminal, the output voltage measured at the output terminal, and a predicted loss value of the converter.
