Abstract A battery system for use in connection with a pair of marine propulsion units, one of which is powered by an internal combustion engine that drives a generator and the other of which is actuated by an electric motor. A pair of actuating batteries are in circuit with the electric motor and the generator and are adapted to selectively provide power to the electric motor or receive a charge from the generator in response to a main switch which is also used to control the starting of the internal combustion engine. A pair of contact relays, responsive to the main switch, are used to adjust the circuitry of the battery system so that the actuating batteries are either connected in parallel in the charging state or connected in series in the actuating state.
A battery system comprising a first propulsion unit having an internal combustion engine and a generator driven by the engine, a starting battery in circuit with the engine for starting the engine, a plurality of actuating batteries, a second propulsion unit having an electric motor operated by said actuating batteries, and relay means for selectively connecting said actuating batteries in parallel for charging said actuating batteries from said generator and connecting said actuating batteries in series for operating the electric motor, and a switch for controlling said relay means and for controlling the starting of the internal combustion engine.

Claim 3
Dependent Claim
53 words
A battery system as recited in claim 1, wherein said switch is moveable between a first and a second position such that when said switch is in the first position said actuating batteries are connected in parallel and when said switch is in the second position said actuating batteries are connected in series.
