Abstract
A battery jump starting connection detection system and method assists in making the best connection to the vehicle battery by detecting the connection resistance to the battery. The connection resistance measurement is taken with the jump start battery isolated from the battery and involves placing a load of known resistance on the battery via the clamps and cabling, and measuring the voltage differential in loaded and unloaded states. The connection resistance is calculated in a main controller, given the loaded and unloaded voltages. As the user adjusts the jump start clamps on the battery terminals in order to get the best possible contact, the system measures the resistance and the results are presented on a display in a meaningful, easy-to-read format such as an LCD display. The user can thus optimize the connection while seeing the results of the optimization in real time.
