Description
- The invention relates to battery chargers, and more particularly, to combined battery chargers and engine jump start systems.
- Currently, there exist dual mode battery chargers configured to charge batteries and provide boost power for engine jump start applications. These dual mode systems typically include a battery charge cable for battery charge applications and an engine jump start cable for engine jump start applications. These two cables may be permanently attached to a control housing or removably attached to two different outlets in the control housing, an outlet for the battery charge cable that is different than an outlet for the engine jump start cable. The operating mode of a dual mode battery charger may be established via a mode switch or other manual process.
- 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.
- In at least one embodiment, the combined battery charger and engine jump start system may include a battery charger subsystem configured to charge a battery and an engine jump start subsystem configured to output sufficient power to jump start an engine. The system may include an output outlet configured to releasably receive one or more output plugs coupled to a cable. The system may automatically determine in which operating mode to operate based on the output plug attached to the output outlet.
- In at least one embodiment, the output outlet may be configured to receive the output plug in a first position within the output outlet such that the output plug is in communication with the battery charger subsystem, and the system may be configured to receive the output plug in a second position within the output outlet such that the output plug is in communication with the engine jump start subsystem. The output plug may be coupled to a cable having positive and negative transmission lines that is usable for both operation of the battery charger subsystem and operation of the engine jump start subsystem. A single multipurpose cable may be configured to be usable for engine jump start processes and for battery charger processes, whereby the single multipurpose cable includes an output plug configured to be removably attached to the output outlet.
- In at least one embodiment, the output outlet may be keyed to prevent a plug from being connected in a misaligned orientation. The output outlet may include a common negative electrical connector and two positive electrical connectors separated by the common return electrical connector. The common negative electrical connector may have a different cross-sectional shape than a shape of the two positive electrical connectors. In one configuration, each of the two positive electrical connectors may have a same cross-sectional shape. Alternatively, the output outlet may include a common positive electrical connector and two negative electrical connectors separated by the common positive electrical connector. The common positive electrical connector may have a different cross-sectional shape than a shape of the two negative electrical connectors. In one configuration, each of the two negative electrical connectors has a same cross-sectional shape.
- In another embodiment, the output plug may be first and second plugs, whereby the first plug is coupled to a charger cable and the first plug may be configured to be attached to the output outlet in the first position and not the second position. The second plug may be coupled to an engine jump start cable and the second plug may be configured to be attached to the output outlet in the second position and not the first position. The engine jump start cable may be configured to be usable for an engine jump start process. The battery charger cable may be configured to be usable for a battery charging process with a second output plug.
- The output outlet may include a common negative electrical connector and two positive electrical connectors separated by the common return electrical connector, or vice versa. In at least one embodiment, each of the common negative electrical connector and two positive electrical connectors may have a different cross-sectional shape.
- The output outlet may include a first connector having a first electrical polarity and a second connector having a second electrical polarity opposite to the first polarity. The second connector may be formed from a second set of connectors having a second electrical polarity opposite to the first polarity. In at least one embodiment, the output outlet or output plug, or both, may include at least one function indicator for identifying a type of cable.
- In another embodiment, the system may include a positive electrical connector and a negative electrical connector, wherein the output outlet is keyed to prevent a plug from being connected in a misaligned orientation. The positive electrical connector may have a cross-sectional shape that is different than a cross-sectional shape for the negative electrical connector.
- An advantage of the system is that the system may automatically place itself in a correct operating mode based on an output plug position, presence or lack of an indicator, or which connectors or pins to which an output plug are attached within a single output outlet.
- Another advantage of the system is that a single output outlet may be used to provide power to both a battery charger cable and to an engine jump start cable.
- Yet another advantage of the system is that a single output outlet may be used with a single cable for both a battery charge process and an engine jump start process.
