Claim 14:
15. The terminal device according to claim 13, wherein the second detection unit comprises two detection terminals configured to detect the voltage between the two ends of the battery detection unit, and the battery protection board further comprises:
a second fault isolation unit, electrically connected to the second 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 second 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 second fault isolation unit is electrically connected to one detection terminal of the second detection unit.
