VEHICLE DUAL BATTERY CONTROLLER UTILIZING MOTION SENSOR

摘要

A vehicle battery and controller combination is provided herein. This combination includes two batteries. Each battery has one positive terminal cell and an associated positive terminal conductor which is independent of any other terminal cell, and an associated terminal conductor. Each battery has one negative terminal cell and an associated terminal conductor which is independent of any other terminal cell. A sensor is provided for sensing current flow between the batteries. A controller is provided which includes a first switch for connecting and disconnecting at least one pair of like poles of the batteries. The controller opens the first switch to allow individual outputs from each battery, opens and closes the first switch to control the charging and discharging of at least one of the batteries and to preserve the state of charge of at least one battery, and closes the first switch to connect both batteries in parallel to receive charge from an alternator. The operation of the first switch is controlled in response to current flow between the batteries which is sensed by the sensor.
