Abstract
A method, device, and computer-readable medium for operating an electrical energy store is provided. The electrical energy store includes a storage cell for storing electrical energy and a control unit. State variables of the electrical energy store are detected. The state variables are transmitted to a computation unit outside of the electrical energy store. The electrical energy store is operated based on operating parameters provided by the computation unit.

A method for operating an electrical energy store (12), which comprises a storage cell (14) for storing electrical energy and a control unit (16), wherein the control unit (16) is configured to detect state variables of the electrical energy store (12), the method comprising:
- detecting state variables via the control unit (16);
- transmitting the state variables detected by the control unit to a computation unit outside of the electrical energy store (12), wherein the computation unit determines estimated state variables of the electrical energy store (12) using the state variables detected by the control unit (16), and wherein the estimated state variables includes at least one selected from the group consisting of:
- temperature, current, and electric charge, and
- operating the electrical energy store (12) based on an operating parameter determined by the computation unit using the estimated state variables, wherein the operating parameter is an internal resistance of the electrical store (12).
