BATTERY COOLING DEVICE AND METHOD FOR COOLING A BATTERY CELL OF AN ELECTRICALLY POWERED AIRCRAFT

A battery cooling device () for cooling at least one battery cell () of an electrically operated aircraft is provided, the battery cooling device () having a first cooling device () configured for absorbing a first amount of heat at least from the battery cell () in an electrical discharging process and thereby cooling it. The first cooling device has at least one latent heat storage unit with a variable state of aggregation. The battery cooling device () also includes a second cooling device (), which is configured for absorbing a second amount of heat from the battery cell () and the first cooling device in an electrical charging process, the second cooling device () being able to be filled with and flowed through by a coolant (). Furthermore, the invention relates to a method for cooling a battery cell of an electrically powered aircraft.
