| 20090027005 | CHARGING DEVICE - The invention relates to a loading device ( | 01-29-2009 |
| 20100219963 | APPARATUS FOR INDICATING THE STATE OF CHARGE OF A STORAGE BATTERY - Storage batteries having a rechargeable battery for operating electric tools often have a state of charge indicator. A state of charge circuit, which has a sensor that is coupled to the evaluation unit, is provided in order to identify the operating state of the storage battery. An interlock switch for preventing indication of the state of the charge is coupled to the evaluation unit. If charging or discharging of the rechargeable battery is identified using the sensor, the interlock switch is used to prevent indication of the current state of charge. | 09-02-2010 |
| 20100221592 | BATTERY PACK - The invention describes a battery pack for a handheld power tool, which can be connected replaceably to a handheld power tool and has a housing, in which a single battery cell is received in the housing. | 09-02-2010 |
| 20100237826 | CHARGER FOR CHARGING AT LEAST ONE RECHARGEABLE ENERGY STORAGE UNIT - The invention relates to a charging device for charging at least one rechargeable energy storage unit, having a defined inner resistance and having a compensation circuit for the compensation of a voltage drop during the charging operation caused by the inner resistance. The compensation circuit has a current detection for detecting a charge current of the rechargeable energy storage unit and a voltage regulator for adjusting the charge voltage to the detected charge current. The charging device is characterized in that the compensation circuit has a voltage distributor between the current detector and the voltage regulator, by the dimensioning of which the compensation of the inner resistance is carried out. | 09-23-2010 |
| 20100237831 | DEVICE, IN PARTICULAR CHARGING DEVICE, FOR CHARGING AN ACCUMULATOR - Charging devices which can be operated in a plurality of manually selectable charging modes and which have a discharging device are known. According to the invention, a storage charge mode which is optimized for storage of the accumulator is proposed. For this purpose, a device for determining the charge state of the accumulator is provided. When the storage charge mode is activated, the accumulator is charged only up to a predefined, optimized partially charged state, in which case the discharging device discharges the accumulator as far as the predefined partially charged state if the charge state which is determined at the start of the storage charge mode is higher than the predefined partially charged state. | 09-23-2010 |
| 20110006729 | RECHARGEABLE BATTERY CHARGING CASE - The invention is based on a rechargeable battery charging case, in particular a cordless handheld power tool case, having at least one battery attachment device and a case body. It is proposed that the rechargeable battery charging case has an electrical energy output and a supply unit, which in at least one operating state is connected to the energy output and to the battery attachment device for supplying the energy output. | 01-13-2011 |
| 20110111270 | BATTERY PACK AND HANDHELD POWER TOOL HAVING A BATTERY PACK - The invention relates to a battery pack comprising at least one battery cell and a housing for accommodating the at least one battery cell. It is proposed that the housing is designed as at least double-walled having at least one inner sheath and one outer sheath. According to the invention, an intermediate volume is enclosed between the at least one inner sheath and the outer sheath. The intermediate volume is able to absorb a pressure wave from an internal volume containing the battery cells. | 05-12-2011 |
| 20110140654 | HANDHELD POWER TOOL CHARGER - A handheld power tool charger, having at least one battery contact device is proposed, which is provided for charging at least one nondiscretely positioned handheld power tool battery. According to the invention, the battery contact device has at least one contact region which is embodied as elongated. | 06-16-2011 |
| 20110143561 | SPARE MODULE FOR HANDHELD POWER TOOL - The invention is based on a spare handheld power tool module, having at least one interface that has at least one contact region and at least one electrical contact that is disposed at least partly in the contact region. It is proposed that the interface has at least one closure unit, which is provided for covering the contact region. | 06-16-2011 |
