    Abstract: A method and apparatus of detecting the states of a battery involve passing test-oriented charging and discharging pulse pair to a battery under test, and retrieving parameters of the battery, such as voltage, current, and temperature, which respond to the charging and discharging pulse pair, so as to estimate the battery states. The battery states include information pertaining to open-circuit voltage, internal resistance, capacitance, state of charge, and state of health of the battery. The battery state-related information is conducive to quick battery state detection and grading.

    Abstract: A liquid cooling battery module includes a collector, a cell liquid cooler, a plurality of cells, a base, an upper lid and a plurality of copper busbars. The cell liquid cooler has a plurality of multi-port extrusion tubes spaced apart equidistantly and parallelly. The collector is in communication with the multi-port extrusion tubes to thereby form a cooling liquid circulation space. The collector has therein an adaptor in communication with the cooling liquid circulation space. The cells are disposed between the multi-port extrusion tubes parallelly and alternately. The base is disposed below the cell liquid cooler. A plurality of cell positioning slots are disposed at the bottom of the base and adapted to contain the cells. The multi-port extrusion tubes serve as heat-dissipating tubes between the cells to enable the liquid cooling battery module to control temperature and attain uniform distribution of temperature quickly and effectively by liquid cooling.

    Abstract: A charging method for a battery set with a plurality of battery cells, having steps of performing a serial charging on the battery cells; determining whether one of the battery cells reaches a saturation voltage; and performing a uniform separately charging on the battery cells when one of the battery cells reaches the saturation voltage, wherein the uniform separately charging comprises sorting the battery cells according to cell voltages of the battery cells; and sequentially and separately charging the sorted battery cells to a Nth segmented voltage in a Nth segmentation, wherein N is a positive integer from 1 to K, and K is a positive integer larger than 1. The charging method of the present disclosure can reduce the temperature rising of the battery cell due to the longtime charging.
