Abstract: A method of detecting false state information reported by a battery unit, wherein the battery unit comprises a monitoring system configured to monitor and report state information of the battery unit. A log of state information reported by the battery unit is inspected in order to determine whether or not there is a change in state information which is inconsistent with normal operation of the battery unit. If there is a change in state information which is inconsistent with normal operation of the battery unit, then it is determined that the battery unit has reported false state information.
