摘要： A device and method is provided that can detect overcharge reliably by separating heat generated by internal resistance and heat chemically generated upon overcharging in a secondary battery. Based on the temperature of the secondary battery detected every first predetermined time by a battery temperature detection section, a temperature gradient operation section calculates a temperature gradient indicating a temperature increase per unit time for every second predetermined time that is longer than the first predetermined time. When a temperature gradient determination section determines that the temperature gradient is larger than a predetermined temperature gradient threshold, which is preset according to the charged state of the secondary battery, N times in a row (where N is a natural number), a fully charged state of the secondary battery is detected.

摘要： Method for determining a determination voltage (end of discharge voltage) of a secondary battery having a nickel-hydroxide positive electrode based on the state of charge of the battery. The end of discharge voltage is determined in consideration of the voltages when the state of charge reaches a permissible lower limit after first and subsequent discharges of the battery. The voltage at which the state of charge reaches the lower limit for discharges after the first discharge gradually decreases due to a memory effect. As a result, the end of discharge voltage is lower than the voltage at which the state of charge reaches the lower limit after the first discharge.

摘要： A device and method of input/output control capable of exhibiting the battery performance by nature by rapidly raising the temperature of the secondary battery by the regeneration at a low temperature. A temperature rise controller controls the temperature rise of the battery pack based on the battery temperature, thereby determining a central value of the state-of-charge control in the range of the state of charge. A battery input/output controller voluntarily controls the state of charge based on the central value of the state-of-charge control from the temperature rise controller and the state of charge at the point of time from the state-of-charge operator, and controls charge and discharge based on the charge and discharge request from the outside to the battery pack.

摘要： Variation of the charged amount among battery blocks composing a battery assembly is detected. By subtracting the detected value of the variation from the width between the upper limit value and the lower limit value of the charged amount, the movable range of the charged amount is found. The position of the present charged amount is detected as the state of charge. For example, it is arranged that both ends of the movable range are 0% and 100%, and that the movable range is the full scale. Then, the position of the charged amount on this scale is specified by the ratio %. The detection of the state of charge in which the variation in charged amount and the change of the movable range are considered, is performed, and on the basis of this state of charge, a preferable charge and discharge control is performed.

摘要： The voltage of each of battery block of a battery is detected by a voltage sensor. Further, the temperature of the battery is detected by a temperature sensor. These detected values are supplied to a detecting section of a battery ECU. A judging section reads out the threshold value of the voltage stored in a memory, on the basis of the detected values of temperature, and compares the threshold value of the voltage with the detected voltage of each of the battery blocks. Then, if at least any one is less than the threshold value of the voltage, a relay is turned off. Furthermore, the threshold value of the voltage is arranged to be the voltage at the moment when the value of the current is suddenly increased by the discharge of a constant current of the battery.

摘要： A method of detecting and resolving a memory effect capable of detecting the memory effect with ease and with high precision and resolving even when the vehicle is in motion is provided. A current in a secondary battery is detected, a variation &Dgr;SOC in a residual battery capacity for a predetermined time period is calculated according to at least current integration by multiplying the detected current by a predetermined charge efficiency (S302), a temperature of the secondary battery is detected and a variation &Dgr;V in a no-load voltage for the predetermined time period is calculated based on the detected current, and an internal resistance corresponding to the detected temperature and the SOC is calculated (S303). A ratio k of the variation in the no-load voltage to the variation in the residual battery capacity is calculated (S304). If the ratio exceeds a predetermined threshold value kst, then the battery is judged to have a memory effect (S307), and the usage range of the SOC is extended for a predetermined time period (S308) or the correction of the SOC using voltages is prohibited for a predetermined time period(S309).

摘要： When a power switch portion 10 is in an open state and a charge/discharge path of the secondary battery 100 is in a disconnected state, an electromotive force calculation portion 109 calculates a battery electromotive force Veq by subtracting a polarized voltage Vpol stored in a polarized voltage storage portion 113 from an open-circuit voltage OCV measured by a voltage measurement portion 102. Based on the electromotive force, a state-of-charge estimation portion 110 estimates a state of charge SOC. Thus, a polarized voltage to be considered for the estimation of SOC can be limited. The state of charge (SOC) of a secondary battery can be estimated with high accuracy and quickly.
