    摘要: Provided are a method of manufacturing an electrode for a secondary battery which can properly maintain the temperature of a hot gas while requiring a smaller amount of hot gas, and a hot-gas drying furnace used for the method. A control device calculates an amount of decrease in temperature of a hot gas at a blowing position of a nozzle (first position) based on a temperature of the hot gas at second position situated downstream of the first position and a temperature of the hot gas at third position situated downstream of the second position. The control device adds the amount to a set temperature of the hot gas at the first position to calculate a modified set temperature. The control device adjusts an output of a heater depending on a difference between the modified set temperature and the temperature at the first position.

    摘要: When a battery current is not larger than a limit current set depending on the battery temperature and is flowing continuously for a predetermined time set depending on the battery temperature or longer, a decision is made that a secondary battery is in stable state. When the secondary battery is in stabilized state, the battery voltage is considered to be equal to the open circuit voltage and SOC estimation is performed based on the open circuit voltage-SOC characteristics. When the product of the internal resistance of the secondary battery and the limit current is made substantially constant (constant voltage) by setting the limit current in association with temperature dependence of the internal resistance, estimation error can be kept within a predetermined range in the stabilized state even if SOC estimation is performed while the battery voltage is assumed as the open circuit voltage. Consequently, SOC can be estimated with high precision within a predetermined error by a simple and reliable system under stabilized state.
