The present disclosure relates to a battery current monitoring method, a controller and a circuit. The method is applied to a current monitoring circuit, the current monitoring circuit includes a hall sensor, a controller and a constant voltage source. The current monitoring method includes: acquiring, by the controller, an output voltage of the constant voltage source and a first analog-to-digital conversion value of the output voltage of the constant voltage source; determining an analog-to-digital conversion correction coefficient based on the output voltage of the constant voltage source and the first analog-to-digital conversion value; acquiring a second analog-to-digital conversion value of an output voltage of the hall sensor and a third analog-to-digital conversion value of a supply voltage of the hall sensor; and determining the battery current based on the analog-to-digital conversion correction coefficient, the second analog-to-digital conversion value and the third analog-to-digital conversion value.
A battery current monitoring method, applied to a controller in a current monitoring circuit, the current monitoring circuit further comprising a hall sensor and a constant voltage source, an output terminal of the constant voltage source being connected to a first input terminal of the controller, an output terminal of the hall sensor being connected to a second input terminal of the controller, a power supply terminal of the hall sensor being connected to a third input terminal of the controller, and the hall sensor being arranged within a power bus of the battery, the current monitoring method comprising:
A controller, comprising a memory and a processor, the memory storing a computer program, wherein the computer program, when executed by the processor, causes the processor to:
A current monitoring circuit, comprising a controller, a constant voltage source having an output terminal connected to a first input terminal of the controller, and a hall sensor having an output terminal connected to a second input terminal of the controller, and a power supply terminal connected to a third input terminal of the controller, the hall sensor being arranged within a power bus of a battery, wherein the controller is configured to:
