    摘要: In an exemplary embodiment, a battery conditioning system monitors battery conditioning and includes a memory for storing data based thereon; for example, data may be stored representative of available battery capacity as measured during a deep discharge cycle. With a microprocessor monitoring battery operation of a portable unit, a measure of remaining battery capacity can be calculated and displayed. Where the microprocessor and battery conditioning system memory are permanently secured to the battery so as to receive operating power therefrom during storage and handling, the performance of a given battery in actual use can be accurately judged since the battery system can itself maintain a count of accumulated hours of use and other relevant parameters. In the case of a non-portable conditioning system, two-way communication may be established with a memory associated with the portable unit so that the portable unit can transmit to the conditioning system information concerning battery parameters (e.g. rated battery capacity) and/or battery usage (e.g. numbers of shallow discharge and recharge cycles), and after a conditioning operation, the conditioning system can transmit to the portable unit a measured value of battery capacity, for example. A battery pack having memory stores battery history and identifying data to be retrieved by a portable battery powered device. Battery status information may be utilized in conjunction with characteristic battery history data in order to optimize charging and discharging functions and to maximize the useful life of a battery pack.

    摘要: A technique for measuring battery characteristics comprises measuring a battery terminal voltage, a charge/discharge current and a charge/discharge time. The technique entails arithmetically determining an integrated power, an integrated charge quantity and an integrating time interval over a period extending from a start of a charge/discharge process to an end thereof, determining a mean terminal voltage by dividing the integrated power by the integrated charge quantity, determining a mean charge current by dividing the integrated charge quantity by the integrating time interval, determining a polarization resistance of the battery on the basis of the mean terminal voltage and the mean current by using a battery polarization resistance model, and finally determining an open-circuit voltage of the battery on the basis of the polarization resistance. The information culled from the above technique may be used to control a charge/discharge process and to predict the remaining life of the battery.

    摘要: In an exemplary fast charging system, a hand-held computerized terminal with rechargeable batteries therein may be bodily inserted into a charger receptacle. The terminal may have volatile memory and other components requiring load current during charging. The system may automatically identify battery type and progressively increase charging current while monitoring for an increase in battery terminal voltage to ascertain the level of load current. The battery temperature may be brought into a relationship to surrounding temperature such that by applying a suitable overcharge current value and observing any resultant temperature increase, the level of remaining battery charge can be determined. For example, if the battery is found to be relatively fully discharged, a relatively high fast-charge rate may be safely applied while monitoring battery temperature. If the battery is initially relatively fully charged or reaches such a state during fast charge, the system may automatically switch to a lower sustainable overcharge rate selected according to battery type and temperature. A preferred system may automatically recharge the battery of a portable device according to an optimum schedule of essentially maximum safe charging rates as a function of battery temperature. The system may also convert a regulated charging current to a pulsed and modulated waveform to provide efficient net charging to the battery. The source of charging current can optionally be placed outside the terminal housing to eliminate any heat dissipation effects of the current source.

    摘要: In a system including volatile memory, a battery backed memory may be available for preserving data in the event of a power failure. Low power condition is reliably sensed sufficiently in advance of supply voltage falling below a minimum operating voltage range so as to give an adequate time interval, e.g. 2.5 milliseconds for the saving of application operating system status. By using a voltage regulator signal which switches in a particularly sensitive manner toward a saturation or zero state well outside its normal control range to trigger a low power signal, such low power signal may provide a time interval of, e.g. from three to six milliseconds of advance warning of impending supply voltage failure. The system is particularly useful for hand-held data processing systems with rechargeable batteries since the regulator may provide its regulator signal as a common control signal for regulating multiple supply paths, and may only trigger the low power signal when all of such supply paths approach a failure condition.

Where an embodiment includes a main battery and a backup battery, the voltage of each may be individually measured, and each may be conditioned. Battery capacity of each may be measured. In a unique low voltage sensing circuit applicable to power sources generally, an automatic voltage regulator may itself sense a low power condition without requiring additional precision components. As an example only, such detected low power condition may be utilized to effect switch over to a backup battery or other auxiliary power supply.

    摘要: A bidirectional current-time integrator device comprises a shunt for connection in a circuit and an integrating circuit having inputs connected to opposite ends of the shunt through a switching device. The integrating circuit integrates an input signal from the shunt with time to produce a stream of pulses at a frequency proportional to the current with each pulse representing a given unit of current time. A bidirectional counter assembly counts the pulses from the integrating circuit in one direction when the current is in one direction, and in the opposite direction when the current reverses. The integrator circuit includes means for storing any partial unit of current time accumulated whenever the current direction changes and adding that partial unit to the subsequent accumulation of the signal when the current changes back to the original direction. The device may be used as a battery discharge state monitor.

    摘要: A microprocessor based electric vehicle traction battery monitoring system evaluates the state of charge, interfaces with a traction motor control system, and controls recharging. The state of charge is evaluated during the first part of discharge by integrating the current after compensating it for rate of discharge and during the last part of discharge by dividing the battery into sub-packs and evaluating the state of charge from the lowest sub-pack voltage compensated for polarization voltage. The charge storage capacity is also calculated from the lowest sub-pack voltage. The maximum traction motor current is progressively limited during the last part of discharge. During charging, the charge withdrawn is replaced while progressively reducing the charging current and the battery is then charged at a constant current until the rate of rise of the lowest sub-pack voltage falls below a fixed level.
