20120037385 | ELECTRIC POWER TOOL POWERED BY A PLURALITY OF SINGLE-CELL BATTERY PACKS - An electric power tool comprises a tool main body, a plurality of battery packs that is detachably attached to the tool main body, and a controller that controls discharges of the battery packs attached to the tool main body. Each battery pack comprises a memory device that stores characteristic data of the rechargeable cell. The controller accesses each of the memory devices of the battery packs and controls the discharges of the battery packs based upon the characteristic data stored in the memory devices. | 02-16-2012 |
20140147718 | HAND-HELD POWER TOOLS AND BATTERY PACKS THEREFOR - A battery pack adapted to be attached to, and drive, a hand-held power tool includes a plurality of series-connected battery cells having a nominal power output of at least 300 Watts. The battery pack weighs less than 275 grams and has a nominal power output to weight ratio of at least at least 1100 Watts/kilogram. A power tool system or kit includes such a battery pack and a hand-held, battery-powered tool adapted to operate with a battery pack having a nominal power output of 600 Watts or more. | 05-29-2014 |
20140151079 | POWER TOOL SYSTEM AND ADAPTER THEREFOR - A power tool system includes a hand-held power tool having a housing with a battery pack interface, an electrically-driven device and a first connector. A battery pack is detachably attached to the battery pack interface and supplies current to the electrically-driven device. An adapter has a second connector physically and electrically connected with the first connector in a detachable manner. The adapter receives power from the battery pack via the hand-held power tool and provides at least one additional electrical function to the hand-held power tool or performs at least one additional electrical function that the hand-held power tool is not otherwise capable of performing. Further, the adapter is at least partially disposed in a space defined in part by the housing and in part by the battery pack when the housing and battery pack are attached to each other. | 06-05-2014 |
20140158389 | THEFT-DETERRENCE SYSTEM FOR POWER TOOL SYSTEM, AND ADAPTER AND METHOD THEREFOR - A power tool system includes a hand-held power tool having a motor or a solenoid that drives a tool, and a first memory that stores at least one pass code. A battery pack is detachably attached to, and supplies current to, the power tool and has a second memory that stores at least one pass code. An electronically-actuatable lock and a first controller are provided in the power tool and/or in the battery pack. The first controller reads the pass codes from the first and second memories when the battery pack is attached to the power tool, directly compares the pass codes from the first memory and the second memory, and causes the first electronically-actuatable lock to prohibit or impair operation of the power tool when the pass codes do not match or otherwise correspond in a predetermined manner. | 06-12-2014 |
20140159640 | CHARGER FOR HAND-HELD POWER TOOL, POWER TOOL SYSTEM AND METHOD OF CHARGING A POWER TOOL BATTERY - A charger for a hand-held power tool includes a power source interface, a charger base and a charging cradle rotatably supported on the charger base. The rotatable charging cradle includes at least two charging output terminals electrically connected to the power source interface. A power tool system includes the charger and the hand-held power tool. A method of charging the power tool system includes contacting charging input terminals of the power tool with the charging output terminals, rotating the charging cradle and the power tool relative to the charging base and supplying charging current to at least one battery cell while the charging cradle and the power tool are allowed to freely swing relative to the charging base. | 06-12-2014 |
20140159662 | PORTABLE BATTERY PACK CHARGING SYSTEM, METHOD FOR RECHARGING A BATTERY PACK, AND ADAPTER THEREFOR - A method for recharging a battery pack includes attaching a portable charger to a user, which portable charger includes or is attached to a self-contained power supply and wherein a first charging port of the portable charger is disposed, e.g., on a belt worn by the user, hanging the battery pack on the belt while the battery pack is physically engaged and in electrical communication with a power tool, and initiating a transfer of power from the charger to the battery pack when the first charging port is at least proximal to a second charging port that is in electrical communication with at least one battery cell of the battery pack. A portable charging system capable of performing this method, as well as an adapter for use in performing this method, are also disclosed. | 06-12-2014 |
20140159919 | Adapter for Power Tools, Power Tool System and Method of Operating the Same - An adapter for a power tool powered by a detachable battery pack includes a connector for directly connecting the adapter only to the power tool in a detachable manner, a controller, at least one memory and/or storage device in communication with the controller, and at least one communication port configured to transmit electrical communications from the adapter controller to a controller located in the power tool and vice versa. The adapter is further configured such that, when a battery pack, which also includes a controller, is connected to the power tool, a communication path is established from the battery pack controller to the adapter controller via the power tool controller. | 06-12-2014 |
20140159920 | ADAPTER FOR POWER TOOLS, POWER TOOL SYSTEM AND METHOD FOR WIRELESSLY COMMUNICATING MAINTENANCE INFORMATION THEREFOR - An adapter for a power tool powered by a detachable battery pack which adapter includes a connector configured to detachably connect the adapter directly to the power tool, an adapter controller, at least one memory and/or storage device in communication with the adapter controller and configured to store maintenance information concerning the battery pack or to store maintenance information concerning the battery pack and the power tool, at least one communication port configured to transmit electrical communications, including said maintenance information, from the adapter controller to a controller located in the power tool and vice versa, and a transmitter configured to wirelessly transmit the maintenance information to an external device. | 06-12-2014 |
