The battery jump starting device 10 is shown in FIG. 8 having cables 56, 58 respectively connected to battery clamps 60, 62 for connecting the battery jump starting device 10 to a battery to be jump started (e.g. vehicle battery). The battery jump starting device 10 can be configured to detachably connect to the set of battery cables 56, 58 respectively having the battery clamps 60, 62 (e.g. positive battery cable with a positive clamp, negative battery cable with a negative clamp). Alternatively, the battery jump starting device can be fitted with battery cables hard wired directly to the device and being non-detachable.

(60) In the first embodiment shown in FIGS. 1 and 4, the left side of the battery jump starting device 10 is provided with POSITIVE (+) cam-lock 24a and NEGATIVE (−) cam-lock 24b. The cam-locks 24a, 24b include receptacles 25a, 25b (FIG. 4) configured for detachably connecting with connecting end 56a (FIG. 11) of the positive battery cable 56 and the connecting end 58a of negative battery cable 58, respectively.

(62) The power circuit 30 comprises two (2) separate Lithium ion (Li-ion) batteries 32 (e.g. two (2) 12V Li-ion batteries) connected to the control switch 18 via a pair of cable sections 34, 36 (e.g. insulated copper cable sections), respectively. The control switch 18 is connected to the reverse currently diode array 48 (i.e. reverse flow protection device) via the cable section 44, and the control switch 18 is connected to the smart switch 50 (e.g. 500 A solenoid device) via cable section 40, as shown in FIG. 9.

The ends of cable sections are soldered and/or mechanically fastened to the respective electrical components to provide highly electrically conductive electrical connections between the electrical components.

(67) In a modified first embodiment shown in FIG. 10, the battery cables 56, 58 are directly hard wired to the reverse current diode array 48 and smart switch 50, respectively, eliminating the cam-locks 25a, 25b, so that the battery cables 56, 58 are no longer detachable.

(68) In a second embodiment of the power circuit to be described below, the cable sections 36, 40, 42, 44 located between the Li-ion batteries 32 and the reverse current diode array 48 and smart switch 50, respectively, are replaced with a highly electrically conductive frame (e.g. rigid frame).

The extension portion 18c has a T-shaped cross section to connect into a T-shaped recess 76e (FIG. 12) in rotor 76 when assembled. The rotor 76 is provided with a flange 76a configured to accommodate the rear extension portion 18b (e.g. round cross-section) therein.

(84) The pair of legs 76c (e.g. U-shaped legs) of the rotor 76 partially accommodate the springs 78, respectively, and the springs 78 apply force against the pivoting contacts 80 to maintain same is highly conductive contact with the selected contacts 82b-92c of the terminals 82-92.

(90) The rear side of the control switch 18 is shown in FIG. 14. Another highly electrically conductive bar 94 is provided on the rear outer surface of the rear housing 74. The fully assembled control switch 18 is shown in FIG. 15.

(91) The second embodiment of the battery jump starting device 110 is shown in FIGS. 20-25 with the cover 112 removed. The cover for the battery jump starting device 110 is the same as the cover 12 of the battery jump starting device 10 shown in FIG. 1-8.

(92) In the second embodiment of the battery jump starting device 110 compared to the battery jump starting device 10 shown in FIGS. 1-8, the cable sections 34, 36, 40, 42, 44, 46 (FIG. 9) in the first embodiment are replaced with a highly electrically conductive frame 170.

(93) The battery jump starting device 110 comprises a pair of 12V Li-ion batteries 132 directly connected to the highly electrically conductive rigid frame 170. Specifically, the tabs (not shown) of the Li-ion batteries are soldered to the highly conductive rigid frame 170.

(94) The highly electrically conductive rigid frame 170 is constructed of multiple highly electrically conductive conductors or frame members 134, 136, 140, 142, 144, 146, 152, 154 connected together, for example, by mechanical fasteners (e.g. copper or aluminum nut and bolt fasteners) and/or soldering. For example, the highly electrically conductive rigid frame members are made of highly electrically conductive copper rods. Alternatively, the highly electrically conductive copper rods can be replaced with highly electrically conductive copper or aluminum plates, bars, tubing, cables, or other suitably configured highly electrically conductive material (e.g. copper stock material of a various cross-sectional shapes, sizes, or gauges). The highly electrically conductive rigid frame 170 comprises highly electrically conductive conductors or frame members 134, 136, 140, 142, 144, 146, which can be insulated (e.g. wrapped, insulated, heat shrink cover) in at least key areas to prevent any internal short circuiting.

(95) The highly electrically conductive rigid frame members can be configured with flattened end portions (e.g. flattened by pressing) each having a through hole to provide part of a mechanical connection for connecting successive or adjacent highly electrically conductive conductors or frame members and/or electrical components together using a highly electrically conductive nut and bolt fastener (e.g. copper or aluminum bolt and nut). In addition, the highly conductive rigid frame member can be formed into a base (e.g. plate or bar portion) for supporting or connecting with an electrical component.

(96) For example, the reverse flow diode assembly 148 has three (3) base portions, including (1) an upper highly electrically conductive rigid bar 148a (FIG. 16) having a flattened end portion 148a a connected to the flattened end portion 144a of highly electrically conductive rigid frame member 144 using a highly electrically conductive fastener 206 (e.g. made of copper or aluminum) having a highly electrically conductive bolt 206a and highly electrically conductive nut 206b; (2) a lower highly electrically conductive rigid bar 148b made from a flattened end portion of highly electrically conductive rigid frame member 144; and (3) a center highly electrically conductive rigid bar 148c made from a flattened end portion of the highly conductive rigid frame member 152.

(97) As another example, the smart switch 150 (FIG. 16) comprises a highly electrically conductive rigid plate 150a serving as a base supporting the solenoid 150b. The highly conductive rigid plate 150a is provided with through holes for connecting the highly electrically conductive rigid frame members to the smart switch 150 (e.g. highly electrically conductive rigid frame member 142) using highly electrically conductive fasteners 206.

(98) The stock material (e.g. copper or aluminum plate, bar, rod, or tubing) selected for construction of the highly electrically conductive rigid frame 170 has substantial gauge to provide high electrically conductivity and substantial rigidity. The “rigid” nature of the highly conductive rigid frame 170 provides the advantage that the highly conductive rigid frame remains structurally stiff and stable during storage and use of the battery jump starting device 110.

(99) For example, the highly conductive rigid frame 170 is designed and constructed to significantly prevent flexing, movement, bending and/or displacement during storage or use so as to prevent electrical shortages of the highly electrically conductive rigid frame touching other internal electrical components or parts of the electronic assembly. This “rigid” nature is important due to the high electrically conductivity path or pathway of electrical power flowing from the Li-ion batteries through the power circuit and reaching the battery clamps 60, 62. It is a desired goal and feature of the present invention to electrically conduct as much power as possible from the Li-ion batteries to the battery being jump started by the battery jump starting device by reducing or minimizing any electrical resistance by using the heavy duty and highly electrically conductive frame 170 arrangement disclosed.

(100) As an alternative, the highly electrically conductive rigid frame 170 can be constructed as a single piece having no mechanically fastened joints (e.g. one piece construction, soldered pieces). For example, the highly electrically conductive frame can be made from a single piece of stock material and then formed into the highly conductive rigid frame. For example, a billet of highly conductive copper can be machined (e.g. milled, lathed, drilled, bent, formed) into the highly electrically conductive rigid frame. As another example, a copper or aluminum sheet or plate can be bent and/or machined into the highly electrically conductive rigid frame 170. As a further alternative, the highly electrically conductive frame 170 can be metal molded (e.g. loss wax process).

(101) As another alternative, the highly electrically conductive rigid frame 170 is made of multiple highly electrically conductive frame members connected together into a unitary structure. For example, the highly electrically conductive rigid frame is made of highly electrically conductive sections of stock material (e.g. copper rod, plate, bar, tubing), which are bent and soldered and/or welded together.

(102) The battery jump starting device 110 further comprises a resistor array 202 (e.g. 12 V 5A XGC) comprising a printed circuit board (PCB) 202a serving as a base supporting an array of individual resistors 202b, as shown in FIGS. 17 and 19. The PCB 202a also supports the dual 2.1 amp (A) USB OUT ports 120c, 120d, the 18A 12V XGC OUT port 20e, and the 5A 12V XGC IN port 20e.

(103) The highly electrically conductive frame 170 can comprise the highly electrically conductive conductors or frame members 134, 136, 140, 142, 144, 146 and one or more electrical components (e.g. control switch, smart switch, plate 150a, reverse flow diode assembly 148) together forming and defining the of the high electrically conductive frame 170.

(104) The highly electrically conductive frame member 170 can at least partially enclose or fully enclosed the batteries 132 in one or more planes of the battery (e.g. plane located perpendicular to x, y, z axes of the batteries 132). Further, the highly electrically conductive frame member 170 are located adjacent to and close to the outer surfaces of the batteries 132 to provide a compact configuration while preventing electrical shorts with electrical components of the rechargeable jump starting device 10.

(105) The left side of the battery jump starting device 110 is also fitted with a pair of light emitting diodes 128 (LEDS) for using the battery jump starting device 110 as a work light. For example, the LEDs 128 are dual 1100 Lumen high-intensity LED floodlights), as shown in FIG. 16. The LEDs 128 are configured to have seven (7) operational modes, including 100% intensity, 50% intensity, 10% intensity, SOS (emergency protocol), Blink, Strobe, and Off.

(106) The battery jump starting device 110 is fitted with a heat sink 129 (FIG. 16) for dissipating heat from the LEDs 128. For example, the heat sink 129 is made of a heat conductive material (e.g. molded or die cast metal plate). The heat sink 129 is provided with ribs 129a transferring heat to the surrounding atmosphere to prevent the LEDs 128 from overheating.

(107) The battery jump starting device 110 is shown in FIG. 16 without any battery cables having battery clamps for connecting the battery jump starting device 110 to a battery of a vehicle to be jump started. The battery jump starting device can be configured to detachably connect to a set of battery cables having battery clamps (e.g. positive battery cable with a positive clamp, negative battery cable with a negative clamp). For example, see the detachable battery cables 56, 58 and battery clamps 60, 62 in FIG. 9, which can be detachably connected to the cam-locks 124a, 124b of the battery jump starting device 110. Alternatively, the battery jump starting device 110 can be fitted with battery cables having clamps hard wired to the device and non-detachable that same or similar to those shown in FIG. 10.

(108) For example, the left side of the battery jump starting device 110 is provided with POSITIVE (+) cam-lock 124a and NEGATIVE (−) cam-lock 124b, as shown in FIG. 16. The cam-locks 124a, 124b include receptacles 125a, 125b configured for detachably connecting with connecting end 56a (FIG. 11) of the positive battery cable 56 and the connecting end 58a of negative battery cable 58, respectively. The cam-locks 124a, 124b can be fitted with sealing caps the same or similar to the sealing caps 26 (FIG. 1) for closing and sealing the receptacles 125a, 125b of the cam-locks 124a, 124b, respectively, during non-use of the battery jump starting device 110.

(109) The battery jump starting device 110 comprises a main printed circuit board 208 serving as a base for LEDs for the control knob 18a and interface 16, and for supporting other electrical components of the battery jump starting device 110.
