Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to starter batteries for car and more particularly, to a car starter battery, which has the characteristics of high capacity, light weight, long lifespan, environment protection and reduction of the load of the car starter, and allows connection to different cars by means of different jumper cables.

2. Description of the Related Art

Lead-acid batteries are commonly used as starter batteries for car. However, a lead-acid battery has low charging/discharging performance and not allow for reversing output polarity. Further, conventional car starter batteries are not highly stable, and may be suddenly over-consumed, causing the driver unable to start the car and leading to travel delay or traffic impact. Further, conventional car starter batteries simply provides a power examination function without automatic power-off and balance charging and discharging control functions. Thus, the problems of battery power attenuation and loss are commonly seen in conventional car starter batteries.

Further, conventional car starter batteries are designed for use in specific models of cars. Different models of cars cannot use one same type of car starter battery. Further, conventional car starter batteries are not applicable in different geographical areas that exhibit significant temperature differences.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a car starter battery, which allows connection to different cars by means of different jumper cables, provides a polarity-reversed output control to fit different cars and a standby power supply for emergency starting.

It is another object of the present invention to provide a car starter battery, which has the characteristics of thermostat control, electrical power and voltage measurement and automatic power-off control, assuring a high level power-supplying stability.

To achieve these and other objects of the present invention, a car starter battery comprises a housing accommodating therein multiple sets of lithium cells, a control circuit assembly for polarity-reversed output control, thermostat control, electrical power and voltage measurement and automatic power-off control, carrying-handle located on the top side of the top cover of the housing, two conducting screw holes located on the top cover at two opposite sides relative to the carrying-handle and electrically connected with the lithium polymer cells for the connection of a jumper cable with conducting screw terminals, and a charging-discharging copper screw detachably threaded into each of the two conducting screw holes for the connection of a jumper cable with conducting terminal clamps.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, a car starter battery in accordance with the present invention is shown. As illustrated, the car starter battery comprises a housing 10, and multiple sets of lithium polymer cells (not shown) set in the housing 10. The car starter battery has the characteristics of high capacity, light weight, long lifespan, environment protection and reduction of the load of the car starter.

The power supply of the multiple sets of lithium polymer cells is majorly adapted for starting the car under a normal condition, and partially used as standby power supply for emergency starting. The car starter battery has built therein a control circuit assembly for polarity-reversed output control, thermostat control, electrical power and voltage measurement and automatic power-off control. As this control circuit assembly is of the known art and not within the spirit and scope of the present invention, no further detailed description in this regard is necessary.

The car starter battery further comprises a carrying-handle 20 located on the top side of the top cover of the housing 10, and two conducting screw holes 40 located on the top cover of the housing 10 at two opposite sides relative to the carrying-handle 20 and electrically connected with the multiple sets of lithium polymer cells in the housing 10 for power input/output.

Further, a charging-discharging copper screw 30 is detachably threaded into each of the conducting screw holes 40 for the connection of any of a variety of jumper cables for different cars (see FIGS. 3 and 4).

The car starter battery further comprises an examination port 50, a power switch 60 and an indicator light 70 located on the back side of the top cover of the housing 10 (see FIG. 2). The examination port 50 is adapted for the connection of a computer for electrical power and voltage measurement and cell failure examination, facilitating repair and replacement of any individual lithium cell. The power switch 60 is adapted for switching on/off standby power supply for starting the car under an emergency condition. The indicator light 70 is adapted for indicating the on/off status of the standby power supply (the power switch 60). Further, a cable may be used to electrically connect the examination port 50 to an analog power meter (not shown) that can be mounted at the dashboard of the car so that the car driver can visually check the power and voltage indications of the analog power meter when driving the car.

FIG. 5 illustrates an application example of the present invention. As illustrated, after removal of the charging-discharging copper screws from the conducting screw holes 40 of the car starter battery, two conducting screw terminals 80 of a jumper cable are respectively connected to the conducting screw holes 40 of the car starter battery for power transmission.

FIG. 6 illustrates another application example of the present invention. As illustrated, two conducting terminal clamps 90 of a jumper cable are respectively fastened to the charging-discharging copper screws 30 in the conducting screw holes 40 of the car starter battery for power transmission.

Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
