摘要： A device (111) for simulating a high battery temperature used in charging a rechargeable cell (101). The device takes advantage of a control signal generated by a voltage control circuit (103) used to disconnect a rechargeable cell (101) from a charging system (105) when a predetermined voltage is reached. The device (111) is generally used with cells having a lithium based chemistry and requiring a different charging regime then nickel chemistry cells. The device (111) is activated by the control signal from control circuit (103) which detects a predetermined voltage from rechargeable cell (101) enabling thermistor (113) to change its state. This change is detected by the charging system (105) which alters its mode of operation from a rapid charging rate to a slower charging rate. The device is retrofitable to existing rechargeable batteries allowing them to be charged using existing charging systems alien to the rechargeable battery.

摘要： 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.

摘要： 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).

摘要： 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.

摘要： A lithium ion battery is provided with an overvoltage switch (12) and an overvoltage control circuit (14). The overvoltage control circuit causes the overvoltage switch to open, thus disconnecting the battery from a charger, upon the battery voltage reaching a first predetermined level when charged by a charger not designed to charge a lithium ion battery. However, when the battery is connected to an appropriately designed charger, the battery receives an input signal through an input terminal (24) which causes the overvoltage control circuit to open the overvoltage switch at a higher second predetermined level, should the appropriately designed charger fail to enter voltage regulation when the battery voltage reaches the first predetermined level.

摘要： A method (200) of charging a multiple voltage battery is disclosed. The multiple voltage battery is characterized by a preselected operating voltage and a charge profile curve having at least two occurrences of the slope thereof being substantially zero. The number of occurrences of the slope of the charge profile curve being substantially zero corresponds to the number of voltage levels the cell is adapted to operate in. The method recognizes the signature charging profile of the multiple voltage level battery and is thus capable of terminating battery charge at the level corresponding to the preselected operating voltage.
