Abstract: CPU power consumption is throttled in relation to the discharge current of a battery pack to prevent battery cells of the battery pack from reaching a critical temperature. When a discharge current measuring circuit detects that discharge current exceeds a threshold level, a throttle signal is activated. In response, a CPU stop control line is modulated to reduce CPU power consumption. When the discharge current falls below another threshold and/or after a prescribed time delay, the throttle signal is withdrawn. The duty cycle of the CPU stop control line is determined as a function of the excess discharge current (i.e., actual discharge current level less safety threshold current level). The more excessive the actual discharge current, the larger the duty cycle on the CPU stop modulation line, and the greater the degree that CPU power consumption is reduced.

Abstract: In a method for detecting a disconnection in the charge line between a generator and an electric battery in a motor vehicle, the generator output voltage is measured and is evaluated at least with respect to the ripple voltage. A disconnection in the charge line is detected when the ripple voltage has reached or exceeded a predetermined ripple threshold value, preferably after the generator output voltage has reached or exceeded a predetermined load shedding threshold value.

Abstract: A compact polarity-insensitive integrated circuit amplifier is described designed to be powered by a miniature low voltage battery of variable polarity. Low current, polarity corrected voltage sources are integrated into functional blocks to supply low current non-bidirectional elements and to provide a constant polarity bias to a substrate of CMOS circuits. Polarity corrected voltage sources are used to provide a polarity sensing function. The invention is embodied in a Class D amplifier which may comprise four n-channel MOSFET transistors arranged in an H-bridge configuration. Additional driver circuitry is described which increases the voltage of the pulse-width modulated input signal to the MOSFET transistors and also performs a pulse trimming function, which reduces parasitic crowbar currents in the amplifier output stage.

Abstract: A power distributing mechanism includes a regulating circuit disposed between at least two circuit portions. The regulating circuit has bifilar-wound windings electrically coupled to the circuit portions. In a first embodiment, the two circuit portions withdraw power from two separate power sources. The regulating circuit, in response to power withdrawn from the power sources passing through the circuit portions, proportionally allocates the withdrawn power between the circuit portions. In a second embodiment, the two circuit portions withdraw power from a single power source. The two circuit portions serve as redundant reliability backup to each other. In the event of circuit failure in one of the circuit portions, the regulating circuit in response to the failure proportionally allocates power to the remaining functioning circuit portion.

Abstract: Battery charging methods and associated chargers which are capable of rapidly charging a battery while subjecting it to reduced levels of overcharging. The methods described are capable of being utilized within numerous battery charging systems for batteries spanning a range of chemistries, such as lead-acid, nickel-based, and lithium-based batteries. Upon detection of the onset-of-overcharge during the charge process, a variable voltage lid is imposed (VLID=&ngr;(&phgr;)+&bgr;log&phgr;+&kgr;&phgr;) which reduces the maximum voltage that may be applied to the battery as a function of charge acceptance which is typically estimated by a calculation based on state-of-charge. Additionally, the voltage lid can be approximated with step-wise voltage lids which are responsive to the level of charge acceptance within the battery.

Abstract: An auxiliary power supply system serves as a consumer's primary power source during selected times and power outages in order to provide the consumer with a continuous supply of AC voltage. A power supply has a rechargeable DC source coupled to an inverter/charger circuit. A first switching means has an input port coupled to an AC voltage source and has an output port. The first switching means, programmable with at least one selected time period, couples the AC voltage source to the output port during a non-selected time period that is different than the selected time period and uncouples the AC voltage source from the output port during the selected time period. A second switching means is coupled to the output port and has a switch coupled between the output port and the inverter/charger circuit. The switch is selectively placed in one of a first position when a normal AC voltage is sensed and a second position when an inadequate AC voltage is sensed. In the first position, the switch is positioned to so that the normal AC voltage is available across the switch and is supplied to the inverter/charger circuit. In the second position, the switch is positioned to receive an AC output voltage from the inverter/charger circuit. As a result, one of the normal AC voltage and AC output voltage is available across the switch at all times.

Abstract: Cylindrical battery modules (9) composed of a plurality of serially connected cells (7) and arranged in parallel and stacked in piles within a holder case (10) are cooled with a forced current of air supplied from the underside. The battery modules (9a) located on the most upstream side of the air current are covered with film tubes (2), so as to prevent them from being cooled more than the other battery modules (9), thereby achieving uniformity in the temperatures of the battery modules. Temperature equalization is further improved by providing film tubes (2) to the several tiers of the battery modules such that the film tubes for covering upstream battery modules (9) have larger diameters than those for downstream battery modules.

Abstract: This invention includes a circuit for charging multiple batteries simultaneously. The circuit monitors the amount of current being delivered to a first battery and compares it to a maximum available current. The circuit then delivers the difference to at least a second battery. The circuit includes a current sensing resistor and comparator for actuating a series switch to electrically couple and decouple a second battery depending upon the demands of the first battery. An optional microprocessor can manipulate a reference threshold to allow simultaneous charging of multiple batteries. The invention greatly reduces the time needed to charge a primary and spare battery.
