1. A vehicle with an electric energy storage device, including a first partial storage device for electric energy and a second partial storage device for electric energy,
wherein the first partial storage device and the second partial storage device are electrically interconnected with each other by a switching arrangement,
wherein the first partial storage device and the second partial storage device each comprise at least one electrochemical storage cell,
wherein the at least one electrochemical storage cell of the first partial storage device has a stability-optimized cell chemistry, and the at least one electrochemical storage cell of the second partial storage device has a power-optimized cell chemistry, and
wherein the at least one electrochemical storage cell of the first partial storage device is arranged in an impact arrangement of the vehicle,
wherein the electric energy storage device has an assembled charge-discharge curve when the switching arrangement is in a third operating mode, and
wherein the assembled charge-discharge curve has a first charge range, in which the power of the electric energy storage device is specified by the first partial storage device, and a second charge range, in which the power of the electric energy storage device is specified by the second partial storage device.
