Abstract:

A battery pack, charger, and terminal blocks for the pack, charger and a cordless power tool are provided. The pack includes battery cells disposed between end caps within a bottom housing of the pack, and a potting boat for housing pack electronics electrically connected to the cells between the end caps and disposed within a pack top housing. A pack terminal block is connected to the potting boat within the top housing. The charger and the power tool each include a terminal block for providing electrical connections between the charger/tool and the battery pack. The terminal block is configured to float side-to-side to provide displaceable movement of the terminal block within the charger housing or tool housing for aligning the battery pack terminal block therein.

Abstract:

A rechargeable battery pack for a power tool can have a data terminal that provides a signal that is indicative of whether the voltage is below a threshold and can serve as both a pre-charge signal for a charger and as a stop-discharge signal for a power tool. A charger can include a power supply circuit and a voltage detection circuit. A charger control module can receive a signal indicative of the voltage of the battery pack and determine a pre-charge time based on the voltage and can monitor a change in the voltage of the battery pack during the pre-charge operation and stop the pre-charge operation based on the change in voltage and the time period.

Assignee:

Black & Decker Inc. - Newark DE

International Classification:

H02J 7/00

US Classification:

320112

Abstract:

A battery pack can include a temperature sensor that can provide an output that is indicative of a temperature associated with the battery pack. A battery management unit can directly measure the temperature sensor when the battery pack is by itself or engaged with a tool. A charger can directly read the temperature sensor when the battery pack is engaged with the charger. Thus, the temperature sensor can be shared by the battery pack and the charger. The battery pack can utilize a same terminal that provides access to the temperature sensor to indicate a stop-charge signal. The charger can read the stop-charge signal on the same terminal used to directly access the temperature sensor.
