Method for monitoring battery arrangement with multiple battery cells for battery system, involves executing control for operating battery arrangement, so that operating range of battery cells is maintained

摘要

The method involves executing a control for operating a battery arrangement (2), so that an operating range of the battery cells is maintained. A parameter with respect to two predetermined parameter ranges is monitored. An error is determined when the parameter is more than a predetermined time period outside the former parameter range and within the latter parameter range. Independent claims are included for the following: (1) a device for monitoring a battery arrangement with multiple battery cells; and (2) a computer program product with a program code for executing the battery arrangement monitoring method.
