摘要： A neural network type of apparatus is provided to detect an internal state of a secondary battery implemented in a battery system. The apparatus comprises a detecting unit, producing unit and estimating unit. The detecting unit detects electric signals indicating an operating state of the battery. The producing unit produces, using the electric signals, an input parameter required for estimating the internal state of the battery. The input parameter reflects calibration of a present charged state of the battery which is attributable to at least one of a present degraded state of the battery and a difference in types of the battery. The estimating unit estimates an output parameter indicating the charged state of the battery by applying the input parameter to neural network calculation.

摘要： A battery condition monitoring system which may be employed in an electric vehicle is disclosed. This system determines a terminal voltage of a battery under discharge of a given current and a consumption of electric energy stored in the battery and calculates a rate of change in terminal voltage of the battery relative to change in consumption of electric energy. When a difference between the rate of change in terminal voltage of the battery and a reference rate representing a rate of change in terminal voltage of a normal battery relative to change in consumption of electric energy is greater than a given value, the system determines that memory effect is occurring in the battery.

摘要： A battery state judging apparatus comprising a voltage detector detecting a voltage at a terminal of a battery, a current detector detecting a charge/discharge current of the battery and an arithmetic operation circuit calculating a residual capacity index of the battery relating to a value obtained by subtracting a quantity of electric charge from a reference capacity value of the battery and calculating a power consumption of the battery from the detected terminal voltage and charge/discharge current. The arithmetic operation circuit estimates a charge/discharge current as a function of the battery residual capacity index and battery power consumption and successively estimates a charge/discharge current in a predetermined power consumption pattern to successively calculate a battery residual capacity index from the estimated charge/discharge current. A battery operable threshold is judged when a battery discharge current, estimated on the basis of an updated battery residual capacity index exceeds a threshold current at that power consumption, and a result is displayed via a display circuit.

摘要： An apparatus for estimating state variables of a secondary battery as an estimation target performs so that a neural network unit studies a true value of a battery temperature, a temperature large value which is larger than the true value of the battery temperature by an approximating temperature sensor detection error, and a temperature small value which is smaller than the true value of the battery temperature by the approximating temperature sensor detection error. After completion of the learning of those values, the neural network unit inputs a battery temperature detected by the temperature sensor, and performs a neural network based calculation to calculate a SOC (state of charge) of the secondary battery. This can drastically increase the calculation accuracy of the SOC of the secondary battery.

摘要： A battery control system is provided which charges or discharges a storage battery installed in a hybrid vehicle to bring a state-of-charge of the storage battery into agreement with a target one. The system determines whether the state-of-charge lies within a given narrower range defined around the target state-of-charge and corrects the state-of-charge based on an open-circuit voltage of the battery when the state-of-charge lies within the given narrower range, thereby eliminating a cumulative error in calculating the state-of-charge of the battery caused by a variation in charge/discharge efficiency of the battery.

摘要： A series hybrid vehicle includes a generator to be driven by an engine, a battery to be charged by the output power of the generator, and a motor for driving the vehicle using the output power sent from the generator and the output power sent from the battery. In an engine control system for the series hybrid vehicle, the values of power demanded by the vehicle when the vehicle is running (i.e., power demand values) are derived based on various engine operation indicative sensor signals, and a running state of the vehicle is estimated based on a frequency distribution of the power demand and a mean value of such power demand values. The system selects one of prestored control patterns depending on the estimated vehicle running state and controls the engine based on the selected control pattern so as to further control the output power of the generator. The system is also applicable to a parallel hybrid vehicle.
