An electrical energy storage system includes electrochemical energy storage cells for collecting, supplying and storing electrical energy, a contacting device for contacting the energy storage cells, and temperature sensors for monitoring temperature of individual energy storage cells. The electrochemical energy storage cells include a first and second electrical terminal, the contacting device including conductors. A first contacting element connects the first electrical terminal of each cell and a first conductor of the contacting device. A second contacting element connects the second electrical terminal of each cell and a second conductor of the contacting device. The temperature sensors include a thermocouple having a first element from a first metal material and a second element from a second metal material. The first element is connected to one of the terminals or the body of the energy storage cell and the second element is connected to the first element or the body of the energy storage cell.
