  • Patent number: 10514426
    Abstract: The present disclosure provides a smart jumper cable having a display module, which comprises a pair of clamps and a control module. The clamps are configured to electrically connect to a vehicle battery; the control module is electrically connected with the clamps through electric wires; the control module further comprises an input port for connecting with an external power supply. The control module comprises a MCU, a switch module and a display module; wherein the display module is electrically connected with the MCU. The switch module is configured to turn on/off the power-supply to the vehicle battery from the external power supply; and the switch module is controlled by the MCU. The smart jumper cable having a display module can display not only the load voltage but also some other working status visually.
