Abstract: A battery apparatus for an electrically driven vehicle, having at least one battery module including individual battery cells is provided. The battery module has a module housing, which, for the purpose of regulating the temperature of the battery cells, is at least partly filled with temperature-regulating liquid and has a primary sealing apparatus to prevent leakage of the temperature-regulating liquid from the module housing. The battery module is furthermore accommodated in a module space of an enveloping housing, which has a secondary sealing apparatus to prevent leakage of temperature-regulating liquid from the enveloping housing.
