摘要： Methods and systems for selectively connecting a plurality of battery cells in a dual-mode battery pack in series and parallel configurations and/or for individual cell monitoring. A dual-mode battery pack may generally include a housing; a first set of battery cells connected in series; and a second set of battery cells connected in series. The battery pack may also include series connection contacts selectively connectable to the first set of battery cells and to the second set of battery cells and, when engaged, connecting the first set of battery cells and the second set of battery cells in a series configuration; and parallel connection contacts selectively connectable to the first set of battery cells and the second set of battery cells and, when engaged, connecting the first set of battery cells and the second set of battery cells in a parallel configuration.

摘要： A battery pack may include a housing, a battery in the housing, a first switch connected to the battery in the housing, a current detector, and a controller. The current detector configured to detect a current flowing to the battery, the current detector being in the housing. The controller configured to control the first switch to switch to a conductive state to flow the current to the battery if the current flowing to the battery detected by the current detector is higher than a first threshold value, and control the first switch to switch to a shut-off state to interrupt the current to the battery if the current flowing to the battery detected by the current detector is equal to or less than the first threshold value, the controller being in the housing.

摘要： A power storage system includes a power generation element that performs environmental power generation, a first storage battery that receives power generated by the power generation element and supplies the power to a load device, a second storage battery that has a capacitance smaller than that of the first storage battery and is connected in series with the first storage battery, a first switcher that is connected in parallel to the second storage battery, short-circuits both terminals of the second storage battery in a closed state, and releases a short-circuited state of the second storage battery in an open state, and a switching unit that controls the opened and closed states of the first switcher.

摘要： The present disclosure discloses a battery management system that uses a small number of opto-couplers to reduce a production cost. The battery management system is controlled to maintain a turn-off state in a normal condition. Also, switches are connected in series, and the switches are connected such that when any one switch turns on, switches connected subsequent to the turned-on switch turn on in sequential order. The turn-on of the last connected switch causes a switch turning on an opto-coupler to be turned on. As a result, when the opto-coupler turns on, a battery management device may transmit information to an external device.

摘要： Die vorliegende Erfindung schafft eine Energieversorgungsvorrichtung für eine zuverlässige Energieversorgung mehrerer elektrischer Verbraucher, wobei die Energieversorgung von mehreren Gleichspannungsquellen bereitgestellt wird. Die Anzahl der Gleichspannungsquellen entspricht der Anzahl der elektrischen Verbraucher. Die Energieversorgungsvorrichtung umfasst ein deaktivierbares Symmetrisierungsnetzwerk. Hierbei werden lediglich die Ausgleichsströme über das Symmetrisierungsnetzwerk geführt, während die Energieversorgung vorzugsweise über eine direkte elektrische Verbindung zwischen Gleichspannungsquelle und Verbraucher stattfindet. Beim Auftreten eines Fehlers kann das Symmetrisierungsnetzwerk deaktiviert werden. Somit wirken sich Fehler in einem Zweig nicht auf die Zuverlässigkeit der Energieversorgung in den übrigen Zweigen aus. Nach dem eine fehlerhafte Komponente lokalisiert und isoliert wurde, können die noch intakten Quellen sowie die intakten Verbraucher durch eine geeignete Konfiguration des Symmetrierungsnetzwerkes wieder in Betrieb genommen werden. Auf diese Weise kann die Verfügbarkeit des Antriebssystems gesteigert werden.

摘要： The present invention relates to a charger device (100) comprising: a sensor (10) which is configured to measure a differential current (DELTA_I) as a difference between a first current (I_POS) through a first battery portion (210) of a battery (200) and a second current (I_NEG) through a second battery portion (220) of the battery (200) and which is configured to provide a current difference signal (ΔI_meas) based on the measured differential current (DELTA_I); a compensator (20) which is configured to calculate a first current setpoint (I_SP_POS) used for the first battery portion (210) and a second current setpoint (I_SP_NEG) used for the second battery portion (220) based on the provided current difference signal (DELTA_I) and a battery current setpoint (I_SP); and a controller (30) which is configured to control charging and/or discharging of the first battery portion (210) based on the first current setpoint (I_SP_POS) and of the second battery portion (220) based on the second current setpoint (I_SP_NEG).
