摘要： PURPOSE:To correctly determine a time when charging of a battery is necessary, by preliminarily setting a current required at an average accelerating time and calculating a voltage of the battery when the set current is discharged from a discharging current from the battery and a voltage of the battery. CONSTITUTION:After a current and a voltage are detected, it is detected whether charging has started from a code of the detected current. Once the charging has started, a process to release charging/polarization is carried out. The flow of the detecting operation is refrained from proceeding until the charging/polarization is released. The detected current is temporarily stored as a change of a capacity. It is detected whether the stored capacity change exceeds a rated capacity. Then, voltage of a battery when the current is discharged which is necessary at an average accelerating time is calculated from a pair of the measured current value and voltage value and stored. Whether a stored count of true battery voltages has reached a regulated value or more is compared, thereby to calculate a true voltage of the battery. The battery voltage of the highest frequency is estimated to be a true value when a predetermined current is discharged. A time when the battery is to be charged, is determined based on the estimated voltage value.

摘要： PURPOSE:To determine the residual capacity of battery accurately by detecting the current being discharged from a battery, along with the voltage thereof, under accelerating state of vehicle after stoppage thereby calculating the internal resistance of the battery. CONSTITUTION:Stoppage of a vehicle is determined and the voltage and current of a battery are read in through a volt meter 4 and an ammeter 5. When a decision is made that a vehicle is accelerating after stoppage, the voltage and current measured at a predetermined time interval are stored continuously until the end of acceleration. Internal resistance of the battery is then calculated based on the measured and stored discharging current and voltage of the battery or the battery voltage under a predetermined discharging current is obtained. Finally, the residual capacity of battery is determined with reference to a data table of the internal resistance vs residual capacity or the battery voltage vs residual capacity and displayed on a monitor.

摘要： PURPOSE:To precisely detect the residual amount of a battery even when a discharge current is changed largely. CONSTITUTION:A correction factor is decided on the basis of an average discharge current from a battery within a prescribed time prior to the resent time. The prescribed time is set to a time or higher in which the discharge polarization of the battery becomes a steady state. A dischargeable capacity is decided in such a way that the full charge of the battery is multiplied by the correction factor, a consumed electric amount is subtracted from the dischargeable amount, and the residual amount of the battery is obtained.

摘要： PROBLEM TO BE SOLVED: To reduce self-discharge during parking of a vehicle by providing a main charging means for charging a capacitor in the specific operating state of an engine before the stop operation of the engine, and a stand-by charging means for charging the capacitor at the rated voltage only for the specified time after detecting the stop operation of the engine. SOLUTION: In an electric circuit of a retarder device with an induction machine functioning as a motor at the time of starting an engine and at the time of accelerating a vehicle, a control device 20 makes the induction machine 3 function as a generator at the time of judging the braking time of the vehicle with a brake depressed. The braking performance of the vehicle is thereby heightened, and mechanical energy is recovered as electric energy to a capacitor 5 and a low pressure battery 9. At the time of ignition off, the idling operation of the engine is maintained, and the induction machine 3 is made function as the generator. A first inverter 4 is controlled to execute charging so that the generated voltage becomes the rated voltage of the capacitor 5, and after the lapse of specified time, the engine is stopped.

摘要： PURPOSE:To improve measuring accuracy by subtracting the integrated discharge quantity of electricity of a battery from full charge, obtaining the integrated residual capacity, obtaining the volt-ampere characteristic of the battery in high-rate discharging, obtaining the residual capacity at the time of a high load, and correcting the integrated residual capacity. CONSTITUTION:In a residual capacity meter 10, the current of a battery 12 is detected with a current sensor 34, the current is integrated and the integrated discharged electric quantity is obtained. This quantity is subtracted from the full charge of the battery 12, and the integrated residual capacity is obtained. Meanwhile, in the capacity meter 10, the voltage of the battery 12 is detected with a voltage sensor 36, and the volt-ampere characteristic is obtained. The characteristic has the excellent correlation with the residual capacity of the battery 12 at the high-rate discharging of the battery 12. Therefore, the residual capacity at the high load is obtained based on this characteristic. The integrated residual capacity is corrected on the basis of the residual capacit at the high load. The corrected integrated capacity is displayed on a display device 14.

摘要： PURPOSE:To properly detect battery residual capacity during the time of driving an electric automobile. CONSTITUTION:Voltage and amperage of a main battery 13 are detected by a voltmeter 15 and an ampere meter 17. When the amperage from the main battery 13 is more than 0.75C and this amperage is in the state of increasing (high load state), V-I characteristics are detected by a V-I characteristic enumeration means 19 by way of taking in the amperage and the voltage at this point of time. In this state, there is a favourable relation between the V-I characteristics and the residual capacity of the battery. Consequently, by previously finding the relation between the both and memorizing it, from the actually found V-I characteristics and the memorized relation, calculation of the residual capacity of the main battery is carried out.

摘要： PURPOSE:To highly accurately measure the residual capacity of a battery of an electric automobile by detecting the electric current flowing through a coil in induction coils, the voltage across the terminals of the battery, and the voltage-current characteristic peculiar to the battery by using the coil as a measurement resistor. CONSTITUTION:When a residual capacity confirmation switch 26 is pressed, a confirmation signal is inputted to a measurement controller. The controller outputs a measurement control signal to an inverter controller 27 upon inputting the confirmation signal. The controller 27 turns on TR1 and TR4 by only driving for example, DR1 and DR4 of drivers 29. As a result, a DC current momentarily flows from a battery 21 through motor coils L1 and L3 of a motor 25. A high-rate discharge current flows to an electric wire connecting the battery 21 with the motor 25 and a current detecting means detects the discharge current.
