Abstract: A mobile power system for electrically powering equipment in a vehicle, where the system contains two electrical circuits operating at two different voltages. One of the two circuits is for providing power to and using power from the batteries onboard the mobile power system, and the other of the two circuits is for providing power to and using power from the vehicle battery. Voltage converting chargers couple the two circuits so that an external source power supply can flow to both electrical circuits, power can flow from one circuit to the other, power can flow from either or both of the two circuits to a combination inverter charger in the mobile power system, or a combination thereof.

Abstract: A solar charging system includes a first battery, a second battery, and processing circuitry. The processing circuitry charges the second battery by supplying electric power from the first battery to the second battery when a state of charge of the first battery is greater than or equal to a prescribed upper limit value, and charges the first battery by stopping supply of electric power from the first battery to the second battery when the state of charge of the first battery is less than or equal to a prescribed lower limit value. A range from the upper limit value to the lower limit value is a range of use of the first battery. The processing circuitry changes the range of use such that the range of use is wider when a degree of degradation of the first battery is high than when the degree of degradation is low.

Abstract: In a maximum power point tracking (MPPT) solar charging system, the solar array is re-configured to have the majority panels connected in parallel, while some panels remain in series for MPPT charge controller. The split wire(s) from the string of panels connected in series can be connected to all the other panels connected in parallel. The split wire is connected to the apparatus_Solar Charge Maximizing controller, to directly power a direct current_DC load, and to charge a battery or battery bank with the same nominal voltage. The solar charge maximizing controller(s) works in conjunction with MPPT charge controller(s) to maximize the total charge current in the ever-changing solar radiation conditions and in the constant changing DC load (inverters in general) conditions.
