Rechargeable battery jump starting device with a dual battery diode bridge system
A rechargeable battery jump starting device with a dual battery diode bridge system. The dual battery diode bridge, for example, is configured to protect against a back-charge to a first 12V battery and/or a second 12V battery after a vehicle has been jump charged to prevent damage thereto.
1. A rechargeable battery jump starting device having a back-charge diode system, the device comprising:
a first 12V battery;
a second 12V battery;
an electrical control switch electrically connected to the first 12V battery and the second 12V battery, the electrical control switch having a parallel switch position for connecting the first 12V battery and second 12V battery in parallel, the electrical control switch having a series switch position for connecting the first 12V battery and the second 12V battery in series;
a back-charge diode bridge connected to the first 12V battery and the second 12V battery, wherein the back-charge diode bridge is a back-charge diode module, the back-charge diode module configured for protecting against a back-charge to the first 12V battery and/or the second 12V battery after a vehicle battery has been jump charged; and
a conductive frame connected to the first 12V battery, the second 12V battery, and the electrical control switch,
wherein the back-charge diode module comprises conductive bars that are portions of the conductive frame.
2. The device according to claim 1 , wherein the back-charge diode module comprises a first channel of diodes accommodating current flow through the first 12V battery, and a second channel of diodes accommodating current flow through the second 12V battery.
3. The device according to claim 1 , wherein the conductive frame comprises a plurality of conductive frame members.
4. The device according to claim 2 , wherein the conductive frame comprises a plurality of conductive frame members.
5. The device according to claim 4 , wherein the conductive bars of the back-charge diode module comprise an upper frame member, lower frame member, and a center frame member located between the upper frame member and lower frame member and spaced apart from each other, the first channel of diodes are connected between the upper frame member and center frame member, the second channel of diodes are connected between the lower frame member and the center frame member.
6. The device according to claim 5 , wherein the center frame member is connected to a positive battery cable.
7. The device according to claim 6 , wherein the center frame member is connected to a positive cam lock configured for releasably connecting the positive battery cable to the positive cam lock.
8. The device of claim 1 , further comprising a smart switch connected to the first 12V battery and the second 12V battery, the smart switch configured for switching on current flow from the first 12V battery and/or the second 12V battery only upon detecting that the positive battery clamp and negative battery clamp are correctly connected to the correct polarity battery terminals of the vehicle battery being jump started.
9. The device according to claim 8 , wherein a negative terminal of the first 12V battery is permanently connected to the smart switch.
10. The device according to claim 9 , wherein the negative terminal of the second 12V battery is selectively connected to the smart switch via the electrical control switch.
11. The device according to claim 1 , wherein a positive terminal of the second 12V battery is permanently connected to the back-charge diode bridge.
12. The device according to claim 11 , wherein a positive terminal of the first 12V battery is selectively connected to the back-charge diode bridge via the electrical control switch.
