System for accurately determining an amount of electrical current flowing through a hall effect current sensor

A system for accurately determining an amount of electrical current flowing through a Hall effect current sensor, comprising:

• a microcontroller operably coupled to the Hall effect current sensor;
• the microcontroller determining an average measured apparent electrical current value based on an electrical current output signal from the Hall effect current sensor, before an electrical current is flowing through the Hall effect current sensor;
• the microcontroller determining a smoothed electrical current offset value based on the average measured apparent electrical current value, an electrical current offset smoothing coefficient, a prior smoothed electrical current offset value, and a prior electrical current offset trend value;
• and
• the microcontroller determining an electrical current offset trend value associated with the Hall effect current sensor based on the smoothed electrical current offset value, an electrical current offset trend smoothing coefficient, a prior smoothed electrical current offset value, and the prior electrical current offset trend value.
