Patent ID: 11522374

Abstract:
A battery saving system (1) for an electrically powered mobility device (13) comprising a battery (15) and a drive control system (16) configured to be powered by the battery, wherein the battery saving system (1) comprises: a current monitoring circuit (3) configured to monitor a load current provided by the battery (15), wherein the current monitoring circuit (3) is configured to determine whether a load current magnitude is below a load current threshold level, a timer circuit (7) having a counter configured to successively count as long as the load current magnitude level is below the load current threshold level, and to reset the counter in the event that the load current level magnitude exceeds the current threshold level, and a disconnecting switch (9) configured to be operated between an open state and a closed state, wherein the timer circuit (7) is configured to trigger the disconnecting switch (9) to obtain the open state when the counter has reached a predetermined number to thereby disconnect the battery (15) from the drive control system (16).
