BATTERY MODULE

The present invention provides a battery module, including a first battery cell arrangement structure, a second battery cell arrangement structure and a bus bar array. The first battery cell arrangement structure and the second battery cell arrangement structure include a plurality of battery cells the battery cell includes a first electrode terminal, a second electrode terminal and a battery housing, and the bus bar array includes a first bus bar. With battery cells stacked in a horizontal direction, a first battery cell arrangement structure and a second battery cell arrangement structure are stacked in a vertical direction, and a first bus bar of a bus bar array is used to sequentially connect the battery cells of the first battery cell arrangement structure and the second battery cell arrangement structure. As a result, a total positive electrode and a total negative electrode of a battery module are located at two ends of the battery module, which greatly reduces the possibility of a short circuit of the battery module and improves the safety of the battery module.
