Claim 13:
14. The terminal device according to claim 13, wherein the first detection unit comprises two detection terminals configured to detect the voltage between the two ends of the current detection unit, and the battery protection board further comprises:
a first fault isolation unit, electrically connected to the first detection unit and the current detection element separately, and configured to shunt, with the current detection element when a circuit electrically connected to a first terminal of the first fault isolation unit is short-circuited, a current passing through the electrochemical cell, so that the two ends of the current detection element are not short-circuited, wherein the first terminal of the first fault isolation unit is electrically connected to one detection terminal of the first detection unit.
