Abstract: A method for evaluating a consistency of a battery pack is provided, including: obtaining an initial/real rated capacity and an initial/real dischargeable electric quantity of each cell in a battery pack after a charge and discharge cycle of the battery pack; generating a first/second data diagram for every cells based upon the initial/real rated capacity and the initial/real dischargeable electric quantity; obtaining a first/second information of key cells in the first/second data diagram, defining an initial/real cell distribution region according to the first/second information by processing the first/second data diagram, and calculating a first/second area of the initial/real cell distribution region; and evaluating the consistency of the battery pack according to the first/second area. A strategy for balancing the battery pack is further provided.

Abstract: A method for generating a data diagram is provided, including: obtaining a first data of each cell in a battery pack during a charge and discharge cycle of the battery pack; calculating a rated capacity and a dischargeable electric quantity of each cell based upon the data obtained; and generating a first data diagram for every cell of the battery pack based upon the rated capacity and the dischargeable electric quantity of each cell. A method for managing the battery pack based on the data diagram is further provided.

Abstract: A charging apparatus includes a heat exchange pipeline, and a refrigerant liquid output pipe and a refrigerant liquid input pipe, which are connected to the heat exchange pipe. The charging apparatus can ensure a vehicle battery can be charged at an optimal temperature range, thereby reducing a charging time of the charging apparatus.
