Abstract: A high frequency battery charger for charging a target battery is provided. The battery charger includes a charging circuit including a high frequency transformer, a switch switching the high frequency transformer, a filter coupled to the high frequency transformer for passing a DC voltage signal and a controller providing a high frequency driving signal to the switch. Measuring circuitry measures at least one of a voltage or a current at the target battery. A microprocessor receives the measured voltage or current and calculates diagnostics of the target battery based on at least one of the measured voltage or current.

Abstract: An expandable cooler is provided. The cooler includes an insulating portion defining a storage cavity and an expandable portion defining a second storage cavity. The expandable portion is adapted to move between an open and a closed position. The expandable portion may be fixedly attached to the insulated portion. In a further embodiment, a telescoping handle is attached to the cooler. A hook is provided on the telescoping handle and is adapted to be received in a corresponding slot in the expandable portion. The expandable portion may be moved between the open and closed position via the handle.

Abstract: A polarity protection circuit for a battery booster device is provided. According to an exemplary embodiment, the polarity protection circuit is comprised of solid-state devices. Preferably no mechanical or electro-mechanical devices, such as solenoids are included in the polarity protection circuit. The polarity protection circuit is electrically connected to the battery to be charged and to the boosting battery. The polarity protection circuit prevents current flow between the batteries unless proper polarity is achieved.

Abstract: A high frequency charger includes a charge circuit for charging a depleted battery and a boost circuit for jump-starting a vehicle. Two separate high frequency transformers are provided for the charge and boost circuits. A selector switch selectively activates at least one of the charging circuit and the boost circuit.

Abstract: A CLA device comprises a CLA plug that is insertable into an external CLA socket, for example, a DC CLA socket inside a vehicle. The CLA device has a housing coupled to the CLA plug, for example, by integration or via a tethered wire, with the housing having a support surface. A port interface connector in the CLA device engages with a complementary port interface connector of an external device at a cantilevered support point when the external device is attached to the CLA device.
