ELECTRIC STORAGE DEVICE FOR PROVIDING ELECTRIC ENERGY FOR A CHARGING OPERATION OF AT LEAST ONE ELECTRICALLY-DRIVEN MOTOR VEHICLE, AND RETROFIT MODULE AND OPERATING METHOD

The invention relates to an electric storage device (10) for providing electric energy for a charging operation of at least one electrically-driven motor vehicle (12). The storage device has: a storage unit (15) for storing the energy, a cooling assembly (27) for providing cooling capacity and a coolant circuit (28) which is designed to convey thermal energy from the storage unit (15) to the cooling assembly (27) by means of a coolant (26). According to the invention, at least one charging cable (17) is coupled to the storage unit (15), each charging cable (17) being designed for connection tothe motor vehicle (12) and having a cooling channel (25), and a distribution system is provided (29), which is designed to divert some of the coolant (26) into the cooling channel (25) of the charging cable (17), or to carry away thermal energy from the cooling channel (25) into the coolant (26) by means of a heat exchanger. 本发明涉及一种电蓄存设备(10)，所述电蓄存设备用于为至少一个可电驱动的机动车(12)的充放电过程提供电能。所述电蓄存设备具有：蓄存单元(15)，其用于蓄存能量；冷却组件(27)，其用于提供冷却
