Multiple battery system and method
First Claim
1. A multiple battery method for a vehicle comprising:
- (a) monitoring a circuit having an electrical load with an electronics control module;
(b) detecting a start event, an engine running event, a recharge event or user input in said circuit with said electronics control module;
(c) when a start event is detected, connecting a starter battery to the electrical load;
when an engine running event is detected, disconnecting the starter battery and connecting an auxiliary battery to the electrical load; and
when a recharge event is detected optimizing the recharging of the starter battery and auxiliary battery with the electronics control module; and
(d) when a user input is detected, checking and displaying a charge status of the first or second battery.

Abstract
A multiple battery system and method for starting internal combustion engines, such as on a boat or vehicle, and for powering auxiliary functions that operate primarily when the engine is not running is disclosed. A first battery is used for starting the engine. A second battery is used to power the auxiliary features associated with the boat or vehicle primarily when the engine is not running. The first battery, referred to as the starter battery, is a high output battery that produces high bursts of energy for limited amounts of time. The second battery, referred to as the auxiliary battery, has a low power output over a fairly long period of time, is capable of being completely drained without harming the battery, and is capable of being fully recharged. The starter battery and the auxiliary battery are connected by a circuit that has an on/off switch controlled by an electronics control module. The auxiliary battery is always on line in the circuit. The electronics control module monitors the circuit to detect certain parameters, such as a start engine event. When a start engine event is detected, the electronics control module connects the starter battery to the circuit with the switch. When the start event is over, the electronics control module disconnects the starter battery from the circuit with the switch. Thus, the electronics control module prevents the starter battery from being drained when power is being drawn from the auxiliary battery during non-start events.

2. A multiple battery system comprising:
-
a starter battery and an auxiliary battery switchably connected to a parallel circuit, the circuit being configured for connection to an electrical load;
an electronics control module that monitors the circuit for start events and charge status requests, the control module connecting the starter battery to the circuit when a start event is detected and generating signals indicative of the starter and auxiliary battery charge status when a charge status request is detected; and
a display for showing the charge status of the starter and auxiliary batteries. - View Dependent Claims (3, 4, 5, 6)
