  • Storage battery with temperture-control device
    Patent number: 6228524
    Abstract: The invention relates to a storage battery with several cylindrical cells, the cell walls of which are in close heat-conducting contact with a temperature-control device. The temperature-control device has at least two hollow bodies (2) through which a temperature-control medium flows, which bodies display semicircular bulges (6), the radii of which correspond approximately to that of the cells (1), and which are arranged in such a way that they fix the spatial positions of the cells (1) to each other.
