A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a gun or group of guns, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles as a vessel's principal offensive weapon, deployed both on surface ships and submarines.

Electric power system for vehicle
ActiveUS20090127930A1Reduce fuel consumptionSimple structureBatteries circuit arrangementsElectric devicesElectric power transmissionTerminal voltage
An ECU in an electric power system for a vehicle controls a DC-DC converter so that an alternator transmits a residual generated electric power to a sub battery while a terminal voltage of a main battery is maintained within an optimally specified voltage range. This residual generated electric power is obtained by subtracting from a maximum generating electric power of the alternator an electric power to be consumed by electric loads and an electric power with which the main battery is charged. This can suppress any fluctuation of the voltage of electric power of the electric power system, namely, the output voltage of the alternator and the voltage of the main battery, and perform a maximum regenerative electric power generation. The sub battery is efficiently changed with the regenerative electric power.

A power delivery system for an electric vehicle provides efficient power management for either continuous or intermittent high-performance operation, using a boost stage and an on-board charging circuit. A main battery, configured as a high-capacity power source, supplies power to the electric motor under normal load conditions. An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode. A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load. In another embodiment, power management can be based on timed intervals.

During external charging, a charger converts AC electric power from an external power supply into electric power for charging a main battery. An AC / DC converter converts the AC electric power on the power line into auxiliary electric power. The charger is further capable of executing power conversion for converting output electric power of the main battery into AC electric power for output to the power line. While a vehicle is running, normally, the charger and the AC / DC converter are stopped, and the auxiliary electric power obtained by converting the output electric power of the main battery by a main DC / DC converter is output. At the time of regenerative braking of the vehicle, where charging of the main battery is prohibited or restricted, the charger and the AC / DC converter are further operated to intentionally increase loss power, thereby generating auxiliary electric power.
