    Abstract: A rechargeable battery (208) is charged using a charger (202). The charge current provided by charger (202) is a stepped-down pulse where the battery charge current rate change is determined by the rise time of the battery voltage. The charge pulse sequence is repeated after the polarization recovery period is completed. The polarization recovery time of the previous period will determine if the stepped-down pulse has to be modified.

    Abstract: A battery pack (12) for powering a device (14) sensitive to input voltage contains a protection switch (28) and a control circuit (26). When the battery pack (12) is charged by a charger (10) and the voltage of the battery pack approaches the maximum safe level of the device (14), the control circuit (26) causes the protection switch (28) to electrically switch open to protect the device (14) from excessive voltage potentially output by the charger. Where the cells (16) are lithium ion cells or a type having a maximum safe voltage, a safety switch (49) is included to interrupt charge current (52) through the cells (16). The safety switch (49) is delayed by resistor/capacitor network (51, 53) so that it switches after the protection switch (28). The safety switch (49) includes a diode (58) to allow the device (14) to remain powered while the safety switch is blocking charge current. Further, diodes (40 and 42) are required to eliminate measurement error of the control circuit (26) if the battery pack (12) is charged through the device contacts (20 and 24).

    Abstract: A modular battery pack (10) is described having several embodiments. In general, the modular battery pack has a battery cell cartridge (12), a circuit cartridge (14), and a housing (16). In conventional battery packs these three elements are combined into one single unit. The invention modularizes these components such that portions may be reused and shared. This results in a more cost effective power system for a portable electrical or electronic device (40) since, once the battery cell or cells (48) have expired, they can be replaced without having to replace the other components, in particular the circuitry.

    Abstract: A battery pack (62) comprises cells (74), and is charged by a charger (64) providing a current level. The charger (64) is a typical nickel-cadmium battery charger providing a first charge current level in excess of an optimum charge current level. The battery pack (62) further comprises a thermal sensing element (76) and an overcurrent charge protection circuit having an overcurrent switch (78), current sense circuit (80), comparator circuit (82), and temperature signal switch (84). If the current level through the cells (74) exceeds the optimum charge current level, the current sense circuit (80) provides a signal to comparator circuit (82) which actuates the temperature signal switch (84), simulating a hot battery pack. The charger (64) then switches to a second charge current level which does not exceed the optimum charge current level. If the charger (64) does not change current levels, a switch delay (86), after a brief period, accumulates enough voltage to actuate a driver switch (88) which opens the overcurrent switch (78), disconnecting the cells (74) from the charger (64).
