Abstract

A vehicle battery boosting device to jump start a battery. The device includes a bank of ultracapacitors, a high current relay, a charge circuit, a voltage monitor and a management circuit. The voltage monitor can monitor voltage at the charge circuit and the bank of ultracapacitors and the high current relay to determine status of the various components of the device. The device can be incorporated into a battery tester and charger cart.
