摘要： A battery module 100 includes a plurality of cells 10 arranged in a grid array. The cells 10 arranged in a row direction are connected together in parallel by a first connecting member 20. The cells 10 arranged in a column direction are connected together such that the cells 10 adjacent to each other in the column direction are connected together in series by a second connecting member 30. When an internal short-circuit occurs in any one of the cells 10, the first connecting member 20 connected to the cell 10 in which the internal short-circuit has occurred is melted by Joule heat generated due to a short-circuit current flowing into the cell 10 in which the internal short-circuit has occurred from the other cells 10 in which no internal short-circuit occurs via the first connecting member 20.

摘要： Provided is a battery pack in which the production of heat due to passage of current in a connector for connecting secondary batteries in parallel is made uniform to increase service life and reduce maintenance costs. A positive terminal connector 14 comprises a connector 14 with through-holes 18. The connector 14 is divided into two regions: a distant region which is distant from the portion connected to an external terminal; and a close region which is close to the connection portion and has the same area as the distant region. The connector 14 is formed so that the open area ratio of the distant region is greater than that of the close region. Thus, the electrical resistance of the close region can be made smaller than that of the distant region. Therefore, the production of heat due to passage of current in the close region can be suppressed.

摘要： A non-aqueous electrolyte battery has a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive electrode has a high-capacity positive electrode portion with a plate area per capacity of smaller than 200 cm2/Ah, and a high-power positive electrode portion with a plate area per capacity of 200 cm2/Ah or larger. The non-aqueous electrolyte battery is advantageous in providing a battery, with use of a single kind of non-aqueous electrolyte battery, which simultaneously satisfies the requirements on high-capacity characteristics capable of performing a long-term continuous discharge, and on high-power characteristics capable of performing a pulse discharge at a large current, without using a hybrid power supply unit which has multiple kinds of batteries and requires a complex control system.
