1. A battery, comprising:
at least two battery units which are connected in series, wherein each battery unit is provided with a casing and two electrode connecting portions which are arranged on two sides of the casing and have opposite polarities, and the at least two battery units connected in series comprise a first battery unit and a second battery unit;
a conductive component arranged on one side of the casing and for being electrically connected to one of the two electrode connecting portions of the first battery unit and the casing of one of the first battery unit and the second battery unit; and
a signal detection component arranged on the other side of the casing and provided with a signal detection circuit for being electrically connected to the other of the two electrode connecting portions of the first battery unit and the casing of one of the first battery unit and the second battery unit, wherein the signal detection circuit and the conductive component are electrically connected to the casing of the same battery unit such that the signal detection circuit can form, along with the two electrode connecting portions of the first battery unit, a detection loop by means of the casing of the same battery unit and the conductive component, so as to detect a temperature or voltage signal of the first battery unit.
