Abstract

An intelligent car battery-charging cable device adapted to provide electrical connections between a first battery and a second battery. The device includes a power controller that regulates power through the device, power cables that connect the power controller to the terminals of the batteries. A triggering device detects proper connection between the power cables and the terminals of the first and second batteries, upon which the triggering device generates a triggering current to activate the relay closing device to close the normally open switch of the relay closing device to close the circuits between the terminals of the first and second batteries. The triggering device is unable to activate the relay closing device and the circuits between the terminals of the first and second batteries, unless the two circuits connected to each of the power cables are both connected to the terminals of the first and second batteries.

Claims

1. An intelligent car battery-charging cable device adapted to provide electrical connections such that a first battery charges a second battery, the device comprising:

a power controller for regulating power in the device;

a first positive power cable is attached to the power controller and comprises a pair of cables each connected to a connection clip for connecting to a positive terminal of the first battery, the connection clip of the first positive power cable, upon connection to the positive terminal of the first battery, is connected to at least two circuits of the power controller;

a first negative power cable is attached to the power controller and comprises a pair of cables each connected to a connection clip for connecting to a negative terminal of the first battery, the connection clip of the first negative power cable, upon connection to the negative terminal of the first battery, is connected to at least two circuits of the power controller;

a second positive power cable is attached to the power controller and comprises a pair of cables each connected to a connection clip for connecting to a positive terminal of the second battery, the connection clip of the second positive power cable, upon connection to the positive terminal of the second battery, is connected to at least two circuits of the power controller;

a second negative power cable is attached to the power controller and comprises a pair of cables each connected to a connection clip for connecting to a negative terminal of the second battery, the connection clip of the second negative power cable, upon connection to the negative terminal of the second battery, is connected to at least two circuits of the power controller;

the power controller comprising a relay closing device bridged between the positive and negative electrodes of the first and the second batteries, the relay closing device comprising a normally open switch and a relay element; and

a triggering device that detects proper connection between the power cables and the terminals of the first and second batteries, upon which the triggering device generates a triggering current to activate the relay closing device to close normally the open switch of the relay closing device closing the circuits between the terminals of the first and second batteries, and when the connection between the power cables and the terminals of the first and second batteries are improper, the triggering device is unable to activate the relay closing device and the circuits between the terminals of the first and second batteries remain open in order to protect the circuits from being damaged due to any improper connection between the power cables and the terminals of the first and second batteries; and

the triggering device is unable to activate the relay closing device and the circuits between the terminals of the first and second batteries unless the two circuits connected to each of the power cables are both connected to one of the terminals of the first and second batteries.
