Abstract: An equipment system includes a battery unit (10) having a monitoring circuit (14), which detects at least one operating parameter of the battery unit (10) and furnishes a control signal, dependent on the operating parameter, for switching means (25, 31). The switching means control the charging and discharging process of the battery unit (10) and are located in the electrical device (20) and in the charger (30), respectively. From the battery unit (10), the control signal is transmitted to the switching means (25, 31) in the electrical device (20) and in the charger (30), respectively. By this provision of shifting the switching means (25, 31) out of the battery unit (10) into the electrical device (20) and into the charger (30), respectively, the heat development in the battery unit (10) and also its structure size are reduced.

Abstract: A monitoring device for an electrical machining tool, in particular for temperature monitoring with an accumulator-driven machine, includes a switch element (12) for separating an electrical consumer (14) from a current supply device (10). For detection of a first operating parameter (TMOTOR) of the consumer (14) and/or the current supply device (10), a first sensor (16) is provided, whereby the first sensor (16) is connected with a display unit and/or with the control input of the switch element, in order to control the switching process as a function of the first operating parameter (TMOTOR). Furthermore, the present invention relates to an electrical machining tool as well as a current supply device with the inventive monitoring device and a corresponding method of operation.

Abstract: A battery unit including a battery (3) is equipped with a monitoring circuit (9) for detecting and evaluating operating variables related to charge state of the battery (3). So that energy is not drawn from the battery (3) by its own monitoring circuit (9) when an external load (2) powered by the battery unit is shut off, the supply of electrical power to the monitoring circuit (9) in the battery unit is disconnected, either immediately or after a certain time delay, when the load (2) is shut off. This slows the discharge of the battery (3) when it is not supplying electrical to the load (2).

Abstract: A battery unit including a battery (3) is equipped with a monitoring circuit (9) for detecting and evaluating operating variables related to charge state of the battery (3). So that energy is not drawn from the battery (3) by its own monitoring circuit (9) when the load (2) powered by the battery unit is shut off, the supply of electrical power to the monitoring circuit (9) is interrupted, either immediately or after a certain time delay, when the load (2) is shut off. This slows the discharge of the battery unit (1) when it is not under load (2).
