Disclosed is an apparatus and method for updating a current pattern for rapid charging, and a computer program stored in a storage medium performing the method, the apparatus includes a resistance calculation unit for calculating an internal resistance of a battery module, a storage unit for storing a current pattern for rapid charging of the battery module, and a calculation unit for updating the current pattern according to a state of the internal resistance of the battery module, and the calculation unit calculates a resistance increase rate based on the calculated internal resistance, calculates an adjustment coefficient based on the calculated resistance increase rate, and updates the current pattern using the calculated adjustment coefficient and the current pattern so that when performing rapid charging, an impact on the battery module life is minimized.

Apparatus, method and computer program for updating current pattern for quick charge

The present invention provides a battery cell of a plate shape, including: an electrode assembly in which a separator is interposed between a positive electrode and a negative electrode, wherein the electrode assembly may be mounted on a receiving part; and sealing parts formed by heat fusion at an external side of the receiving part, wherein lateral sealing parts adjacent to one of the sealing parts at which an electrode terminal is positioned may closely contact an outer surface of the receiving part while being bent toward the receiving part of a battery case, and a phase change material (PCM) that is phase-changed in response to a thermal change may be added to surplus surfaces of the lateral sealing parts or to surplus spaces between the receiving parts and the bent lateral sealing parts.
