The invention provides a current detection circuit, a current detection method, electronic equipment, a storage medium and an electric vehicle. The current detection method comprises the steps that voltages at the two ends of a shunt are acquired, and a first current value is calculated based on the voltages at the two ends of the shunt; acquiring a detection result of the current sensor, and determining a second current value based on the detection result of the current sensor; judging whether the first current value is greater than a preset threshold value or not; when the first current value is smaller than the preset threshold value, determining the first current value as a current detection result of the battery system; and when the first current value is greater than or equal to the preset threshold value, determining the second current value as a current detection result of the battery system. According to the invention, wide-range current detection can be realized, and relatively high detection precision and relatively low hardware cost are ensured.
