1. A battery module, comprising:
a battery cell component, comprising at least two battery cells arranged in a preset direction;
a conductive element, wherein adjacent battery cells are electrically connected through the conductive element; and
a protection circuit board, wherein battery cells located at two ends of the battery cell component are electrically connected to the protection circuit board through corresponding tabs, respectively,
wherein the conductive element comprises: a connecting part and a detecting part, and wherein one end of the detecting part is directly connected to a middle of the connecting part, and another end of the detecting part is directly electrically connected to the protection circuit board; and the connecting part is connected to the battery cell, wherein the conductive element is in a “T” shaped structure,
wherein each of the battery cells comprises a positive tab and a negative tab;
a positive tab of the battery cell at one end of the battery cell component is electrically connected to the protection circuit board, and a negative tab of the battery cell at the other end of the battery cell component is electrically connected to the protection circuit board; and
a negative tab of adjacent one battery cell is electrically connected to a positive tab of adjacent another battery cell through the conductive element,
wherein the conductive element is coated outside the positive tab and/or the negative tab; and a first part of the conductive element is located on a first surface side of the battery cell, and a second part of the conductive element is located on a second surface side of the battery cell, and an interval exists between a plane where the second surface side is located and the tab.
