Vehicle dual battery controller utilizing motion sensor
First Claim
1. A vehicle battery and controller combination having(a) two batteries, where each battery has one positive terminal cell and associated positive terminal conductor independent of any other terminal cell and associated terminal conductor where each battery has one negative terminal cell and associated terminal conductor independent of any other terminal cell,(b) a sensor for sensing current flow between the batteries;
- and(c) a controller comprising a first switch for connecting and disconnecting at least one pair of like poles of the batteries, where the controlleropens 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 the alternator;
wherein the operation of the first switch is controlled in response to current flow between the batteries sensed by the sensor.

Abstract
A vehicle battery and controller combination having two batteries where each battery has one positive terminal cell and associated positive terminal conductor and one negative terminal cell and associated terminal conductor. Each terminal cell is independent of any other terminal cell. The controller includes a first switch capable of connecting one or more pairs of like poles of the batteries. The first switch opens to allow individual output from each battery, opens and closes 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 to connect both batteries in parallel to receive charge from the alternator.
