Method for jump starting a vehicle

摘要

A method for jump starting a vehicle comprising causing a control unit to set a reference voltage by choosing a point from a chart plotting voltage across a starting battery versus time during a vehicle start; determining whether the voltage across a starting battery of the vehicle is less than the reference voltage; closing a switch if the determination is positive, thereby causing an external power source to supply high current to the starting battery; adding the high current and current from the starting battery to obtain a total current; and supplying the total current to a starter motor of the vehicle so as to start the vehicle. An apparatus for thus jump starting a vehicle is also disclosed.

1. A method of jump starting a vehicle comprising the steps of:
measuring a range of voltages across a starting battery of the vehicle during a process of starting the vehicle; setting a reference voltage point Q by choosing the point Q from the range of voltages across the starting battery of the vehicle measured during the process of starting the vehicle; and in a given starting process, employing a controller to: determine whether the voltage across the starting battery of the vehicle is less than the reference voltage Q; and if the determination is positive, cause an external power source to supply high current (I2) to the starting battery, thereby adding the high current (I2) to current (I1) from the starting battery to obtain a total current (I); and supplying the total current (I) to a starter motor of the vehicle so as to successfully start the vehicle.
