  • Patent number: 10629964
    Abstract: The present invention relates to a method for operating an energy storage unit having a plurality of battery cells (1) electrically connected to one another, each battery cell comprising an over-voltage protection device and a cell protection, wherein an adjacent battery cell voltage (14) on each battery cell (1) of the energy storage unit is monitored to determine whether said battery cell voltage is larger than a predetermined cell voltage minimum value (16), wherein the energy storage unit is switched off when the battery cell voltage (14) drops below the cell voltage minimum value (16). Thereby the battery cells (1) are monitored with respect to a triggering of the respective over-voltage protection devices, wherein the energy storage unit is further operated if a battery cell voltage (14) of a battery cell (1) of the energy storage unit exceeds the cell voltage minimum value (16) and the triggering of the over-voltage protection device of this battery cell (1) is thereby detected.

  • Patent number: 10522876
    Abstract: Detection of corrosion within an at least partially electrically conductive housing of an electric energy storage unit. The electric energy storage unit has a positive terminal and a resistance element between the positive terminal and the housing. State of charge values of the electric energy storage unit for at least one first instant of time and at least one second instant of time are determined. An electrical isolation resistance value between the housing of the electric energy storage unit and at least one reference point for at least one third instant of time may also be determined. A first comparison of a difference of the determined state of charge values with a predefined state of charge difference value for the electric energy storage unit and/or a second comparison of the determined electrical isolation resistance value with a predefined electrical isolation resistance value for the electric energy storage unit are performed.

  • Patent number: 9876261
    Abstract: A monitoring device for a battery, a lithium-ion battery with the monitoring device and a method for the monitoring of a battery, wherein the battery is provided with a plurality of cell composites comprising a number of mutually parallel-interconnected battery cells. The cell composites are also interconnected by means of electrical cell couplers, and one or more temperature sensors are arranged between the cell composites. Where a voltage drop across one or more of the battery cells on the electrical cell couplers exceeds a predetermined value and, simultaneously, a temperature occurs on at least one of the temperature sensors which exceeds a predetermined value, a fault signal is generated. The defective battery cell can then be isolated from the cell composite.

  • Publication number: 20160172635
    Abstract: A battery cell, preferably a lithium ion battery cell, includes a prismatic or cylindrical housing with two opposite sides. The first side of the two opposite sides of the housing is partially or completely at cathode potential. The second side of the two opposite sides of the housing is partially or completely at anode potential. One of the two opposite sides additionally has a circumferential edge protruding partially or completely from the surface, while the other of the two opposite sides has a circumferential edge that is partially or completely recessed relative to the surface. The battery cell can be easily joined to other battery cells by stacking to form battery modules, making it possible to avoid expensive connecting techniques and production processes. The battery cell is included in a battery module and a motor vehicle that has an electric drive motor and a battery system.
