Abstract: A handheld device for jump starting a vehicle engine includes a rechargeable lithium ion battery pack (32) and a microcontroller (1). The lithium ion battery is coupled to a power output port of the device through a power switch circuit (15) actuated by the microcontroller. A vehicle battery isolation sensor (12) connected in circuit with positive and negative polarity outputs detects the presence of a vehicle battery (72) connected between the positive and negative polarity outputs. A reverse polarity sensor (10) connected in circuit with the positive and negative polarity outputs detects the polarity of a vehicle battery connected between the positive and negative polarity outputs, such that the microcontroller will enable power to be delivered from the lithium ion power pack to the output port only when a good battery is connected to the output port and only when the battery is connected with proper polarity of positive and negative terminals.

Abstract: A portable or handheld jump starting and air compressing apparatus for jump starting a vehicle engine and air inflating an article such as a tire. The apparatus can include a rechargeable lithium ion battery or battery pack and a microcontroller. The lithium ion battery is coupled to a power output port of the device through a FET smart switch actuated by the microcontroller. A vehicle battery isolation sensor connected in circuit with positive and negative polarity outputs detects the presence of a vehicle battery connected between the positive and negative polarity outputs. A reverse polarity sensor connected in circuit with the positive and negative polarity outputs detects the polarity of a vehicle battery connected between the positive and negative polarity outputs.

Abstract: A dynamic battery charging method for use in a battery charger configured to charge a lead acid battery, including marking a time when battery charger switches from Constant Current (CC) phase to Constant voltage (CV) phase to establish CV Start Time; starting at CV Start Time; calculating Delta Current by subtracting current measurement at particular time interval from previous current measurement at an earlier time interval; terminating CV phase once Delta Current is less than or equal to a particular Delta Current current level OR once the battery charger operating current drops below a particular battery charger operating current; marking CV Finish Time; switching back to another CC phase once CV phase is terminated; and staying at another CC phase for a time period equal to the CV Finish Time minus CV start Time OR until lead acid battery reaches CV voltage plus an additional voltage amount to complete charging.
