Abstract
The utility model refers to an automobile start-up adapter, wherein it comprises a shell and a circuit board provided inside the shell. The shell is provided with an input terminal for electrically connecting with an output terminal of a lithium battery of a power tool and an output terminal for electrically connecting with a clamp. The input terminal and the output terminal are communicated through a circuit board, and a voltage identification circuit and a voltage conversion circuit are provided on the circuit board. The automobile start-up adapter of the utility model can use the lithium battery of the hand-held electric tool to supply power for the emergency start-up of the automobile.
Claims20
An automobile jumpstart adapter comprises:
- an enclosure having a shell;
- an input terminal, a jumpstart output terminal, and a circuit board disposed within the shell;
- wherein the circuit board comprises an integrated circuit, a voltage identification circuit, a voltage conversion circuit, and a polarity detection circuit, the polarity detection circuit being in electrical communication with the integrated circuit;
- and
- a Universal Serial Bus (USB) interface being arranged on a single outer side of the shell as the jumpstart output terminal,
- wherein the input terminal is configured to electrically connect to a portable battery output terminal and the jumpstart output terminal, the voltage identification circuit identifies an appropriate output voltage corresponding to a vehicle battery and the voltage conversion circuit converting power from the portable battery to the appropriate output voltage, wherein the enclosure is configured to be attached on one side of the portable battery.
A method for jumpstarting an automobile, the method comprising:
- receiving, at a shell of a jumpstart adapter, power from a portable battery at a first voltage, wherein the jumpstart adapter comprises an input terminal, a jumpstart output terminal, and a circuit board disposed within the shell, and a Universal Serial Bus (USB) interface being arranged on a single outer side of the shell as the jumpstart output terminal, wherein the circuit board comprises an integrated circuit, a voltage identification circuit, a voltage conversion circuit, and a polarity detection circuit, the polarity detection circuit being in electrical communication with the integrated circuit;
- identifying, by the voltage identification circuit, an appropriate voltage corresponding to a vehicle battery;
- converting, by the voltage conversion circuit, the received power from the portable battery to the appropriate voltage identified by the voltage identification circuit;
- removing a dust cover that shields the Universal Serial Bus (USB) interface and the jumpstart output terminal on the single outer side of the shell;
- determining if the polarity of the vehicle battery is correct by the polarity detection circuit;
- and
- if the polarity is correct, attaching the vehicle battery to a side of the shell and providing to the vehicle battery, through the jumpstart output terminal, the received power converted to the appropriate voltage or if the polarity is not correct, no power is provided to the vehicle battery from the portable battery.
