The cell sampling circuit includes: a plurality of target units sequentially connected in series by a daisy-chain communication method, a transformer unit being connected between every two adjacent target units; wherein the target unit ranked first in the series connection is a main control unit, and the rest of the target units are all cell sampling units; each of the target units is configured to acquire an impedance of the transformer unit connected thereto, and judge, based on the acquired impedance, whether to perform a circuit abnormality early warning.",
