Abstract: A battery system for use in a vehicle is disclosed having a first battery for selectively powering the motor to start the engine, and having a first voltage level and a charge level. The system includes a second battery to operate and maintain the accessory electrical loads, and having a second voltage level. The system includes a charging switch coupling the first battery to the alternator. The system also includes a charge maintenance device coupling the first battery to the second battery to maintain the charge level of the first battery to a predefined magnitude in response to a control signal. The system also includes a controller coupled to both the first battery and the second battery to monitor the first voltage level and the second voltage level, and operating the charging switch and the charge maintenance device in response to the first voltage level and the second voltage level.

Abstract: A modular electric storage battery is adaptable to a variety of applications, and for example, as a starting, lighting and ignition (SLI) battery of a car, truck, motorcycle, lawn and garden equipment or other internal combustion engine powered product. The modular battery is constructed from a plurality of battery cells assembled into a battery housing. The cells are sealed, maintenance-free, rechargeable cells. The housing includes quick connect termination, and the starting application is adapted with a base unit having complementary termination. The modular battery and base unit also include aligning features to ensure proper interconnection of the battery terminals. The base unit may be adapted to receive several sizes of modular battery. In addition, a second modular battery, that may be configured as a flashlight or other device, is provided and can inter-connected with the base unit to provide a jump starting capability.

Abstract: Battery powered equipment is provide with a controller which monitors the voltage supplied by the battery. Should the battery voltage drop below a preset level when the equipment is inactive, the controller disconnects non-essential loads of the equipment from the battery to conserve what charge remains in the battery. When used with a motor vehicle the controller may be tied into the security system and disable the ignition during inactive periods unless the proper reactivation signal is received.

Abstract: An electrical system of a vehicle has a starting battery and a reserve battery. The charge of the starting battery is maintained by a charge maintenance device under control of a controller which couples energy from the reserve battery to the starting battery during periods when the vehicle is not being used or during periods of operation where the starting battery voltage requires additional charge.

Abstract: A control circuit for controlling the recharging of two batteries in a dual battery vehicle electrical system includes a charging circuit (20) for stepping up the voltage of a reserve battery (RES.), so that it can be applied to a starting battery (HPB), an alternative circuit path (18, 19) to allow charging of both batteries by the alternator (A) when the vehicle engine is running, and a controller (30) for switching the connection of the batteries through the charging circuit (20) and the alternative circuit path (18, 19) under various combinations of conditions.

Abstract: A metal oxide-hydrogen battery incorporating a system for maintaining a substantial uniform range of pressure of hydrogen gas in the battery. The battery includes an outer pressure vessel and a plurality of cells are contained in the vessel. A liquid electrolyte is impregnated within the cells and the battery is charged with hydrogen gas. A conduit connects the interior of the vessel with a venting zone, preferably a closed chamber, containing a hydrogen absorbing material. A first valve is located in the conduit and is designed to open when the battery is discharged to a preselected level. A second pressure regulated valve is also mounted in the conduit and opens to vent hydrogen from the vessel to the chamber, if the hydrogen pressure exceeds a predetermined value at the preselected state of discharge. The sequential venting of hydrogen during cycling of the battery will maintain the pressure of hydrogen in the vessel within a given range.
