  • Patent number: 9761887
    Abstract: An energy storage apparatus having a housing, a plurality of battery cells, a temperature-control system with a liquid temperature-control medium for cooling and/or heating the battery cells in the housing. An absorbent element is arranged spatially between the battery cells and the housing such that any temperature-control medium escaping from the temperature-control system is absorbed by the absorbent element. The absorbent element is separated from the battery cells by an electrically insulating layer, the electrically insulating layer being impermeable to the temperature-control medium.

  • Patent number: 9034506
    Abstract: A battery having a plurality of voltage-generating cells which are arranged in particular adjacent to one another. The battery has a plurality of fastening/bearing points which are spaced apart from one another and on which the battery is fastened or bears. At least a first portion of the cells have a first mass, and optionally further include parts of the battery with an additional mass, and which come to rest between the fastening/bearing points. The first portion of the cells absorbs at least a substantial part of the bending/shear load arising in the battery between the fastening/bearing points. In addition, an I-shaped or H-shaped intermediate element is arranged between at least two voltage-generating cells.

  • Patent number: 8922164
    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.
