Abstract: A multiple bank battery charging system for charging two or more battery circuits simultaneously via voltage control only is disclosed. The multiple bank battery charging system does not monitor current of the charging current nor use current to control generation of the charging current. Instead, the multiple bank battery charging system only monitors voltage of the charging current generated by a controller. The multiple bank battery charging system may include a single output for sending the charging current to the multiple battery circuits for charging. As such, the multiple bank battery charging system is configured to charge multiple battery circuits simultaneously via a charging current discharged on a single outlet. The multiple bank battery charging system may also be configured to charge batteries having any battery chemistry.

Abstract: A battery management system for two or more battery circuits on a vessel in which the battery circuits may be charged by a motor on the vessel or by a power source positioned remotely from the vessel is disclosed. As such, the two battery circuits may have different nominal voltages configured to provide different voltages to different devices onboard the vessel. The battery management system may receive input power from the motor on the vessel to charge the battery circuits on the vessel. The battery management system may be configured such that when the battery management system is not receiving power from a motor on the vessel, the battery management system may receive power from a power source positioned remotely from the vessel, such as, a municipal power supply. The battery management system may also include a communication system enabling battery management data to be shared with users.

Abstract: Battery charging in a battery charging system (BCS) involves measuring an output voltage of a battery connected to the BCS and determining an output voltage type of the battery. The battery is also evaluated to determine a condition of the battery for accepting a charge. Based upon the evaluation the BCS performs can automatically initiate a charge cycle for the battery in accordance with the battery output voltage type which has been determined. The BCS can also trigger an indication that the battery is not in condition for accepting a charge. A range of output charging voltages is produced using a transformer, and a switch network.

Abstract: Systems/methods for operating a solar charger system. The system comprises: preventing, by a first circuit, damage to the solar charger system when a reverse polarity connection exists between a solar panel and the solar charger system; preventing, by a second circuit, damage to the solar charger system when a reverse polarity connection exists between the battery and the solar charger system; preventing, by a third circuit, damage to the battery when a temperature of a surrounding environment exceeds a pre-defined value while the battery is being charged by the solar charger system; and preventing, by a fourth circuit, back-feed from the battery without any voltage drop or loss while the battery is being charged by the solar charger system.

Abstract: A combined battery charger and engine jump start system configured to automatically determine in which operating mode to operate based on the output plug attached to an output outlet is disclosed. For instance, the system may include a single output outlet and a single cable capable of being attached to the single output outlet in multiple positions to enable the system to automatically operate in the correct mode. In another embodiment, the system may include a single output outlet and a cable for a battery charger process and a cable for an engine jump start process whereby a cable position or plug configuration enables the system to automatically operate in the correct mode. As such, the system is more cost effective to manufacture and more reliable in that the system is automatically places itself in the correct operating mode when a cable is attached thereto.

Abstract: Cellular communication network is managed by receiving at a computing device certain data specifying geolocation information of one or more user equipment in communication with one or more nodes of the cellular communication system. The computing device identifies a disruption in receipt of the periodic geolocation information, and uses the received geolocation information to at least partially define a location of a peripheral edge of a communication dead zone. The peripheral edge information is used to facilitate a dynamic modification or control of the cellular communication network and/or the user equipment.
