Charging control method for secondary battery and control device

摘要

The disclosed device for controlling charging of a secondary battery includes a step for calculating an amount of heat generated by a secondary battery on the basis of an inter-electrode-plate voltage, internal resistance, a current value, and charging efficiency; a step for calculating an amount of allowable generated heat of the secondary battery on the basis of a temperature of the secondary battery and the cooling ability of a cooling means that cools the secondary battery; and a step for limiting the charging power of the secondary battery when the aforementioned amount of heat generated is greater than the aforementioned amount of allowable heat generation.

主权项

1. A method for controlling charging of a secondary battery, the method comprising:
calculating an amount of heat generated by a secondary battery based on an inter-electrode-plate voltage, an internal resistance, a current value, and charging efficiency of the secondary battery; calculating an amount of allowable heat generated by the secondary battery based on a cooling ability of a cooling unit which cools the secondary battery and a temperature of the secondary battery; and limiting, by using a charging control device, charging power of the secondary battery when the amount of generated heat is greater than the amount of allowable generated heat, wherein the charging efficiency of the secondary battery includes a ratio of an amount of electricity actually stored with respect to a charging electric charge amount.
