    摘要: A battery charger and method is disclosed for detecting when a battery has a low state of health while simultaneously charging or maintaining the battery. A battery charger includes a processor; a non-transitory memory device; a power management device to receive an input power and to output a charging current; a pair of electrical conductors to electrically couple with a battery, and a display electrically coupled to the processor. The display being configured to indicate a bad battery indicator when the battery has a low state of health and whether the battery is good to start.

    摘要: Described is a battery booster for jumpstarting a vehicle having an external battery. The battery booster includes a set of electrical conductors, a power supply to supply a starting current to jump start the vehicle via the set of electrical conductors, a boost switch positioned in-line between the power supply and a set of battery clamps on one of the set of electrical conductors; and at least one processor to output a control signal to close the boost switch as a function of one or more parameters of the power supply, the external battery, and/or the vehicle. The set of electrical conductors couple with the external battery or with an engine that is electrically coupled with the external battery via the set of battery clamps. The set of electrical conductors includes a positive electrical conductor and a negative electrical conductor. The power supply includes a plurality of lithium battery cells arranged to form a lithium battery having a positive terminal and a negative terminal.

    摘要: A battery booster for jumpstarting a vehicle having an external battery. The battery booster may include a processor, a set of terminal connectors, a power supply, and a power-management circuit. The set of terminal connectors may be configured to couple with the external battery or an engine that is electrically coupled with the external battery. The power supply may include a lithium battery configured to supply a starting current to jump start an engine. The external battery may have a first nominal voltage, while the lithium battery may have a second nominal voltage that is greater than the first nominal voltage. The power-management circuit operatively coupled with the at least one processor, wherein the at least one processor is configured to transfer power selectively between the external battery and the power supply. The processor is configured to perform a pre-charge function and/or a back-feed function via the power-management circuit, which may employ a pulse width modulation (PWM) driver.
