An electronic device is provided with built-in battery, a first latch for locking first battery, and a second latch for locking second battery. The electronic device also includes: first switch alternatively selecting a battery for supplying power to the electronic device from first battery and second battery; and second switch for switching on and off the supply of power from built-in battery to the electronic device. The electronic device is additionally provided with a latch opening/closing detector for detecting opening and closing of the first latch and the second latch, battery remaining amount detector for detecting remaining amounts of first battery and second battery, and a power controller for controlling first switch and second switch. The power controller controls first switch and second switch based on detection results of latch opening/closing detector and battery remaining amount detector.

A fast charging high energy storage capacitor system jump starter is described. The jump starter apparatus incorporates a method of using reserve energy from a depleted electrical system such as an automobile battery or using energy from another energy source, combined with a fast charging high energy capacitor bank to enable the rapid and effective way to jump start a vehicle.

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.

A portable or handheld device or apparatus for jump starting a vehicle engine having a depleted or discharged starting battery. The portable or handheld device or apparatus for jump starting a vehicle engine includes a rechargeable lithium-ion (Li-ion) battery pack and a battery cell equalization circuit configured to prevent overcharging of one or more individual lithium-ion battery cells, which can cause fire, damage to the battery pack and device or apparatus for jump starting a vehicle, or personal injury to a user.

A rechargeable battery jump starting device with a control switch (e.g. rotary control switch) and an optical position sensing switch system to determine the position of the control switch. The optical position sensing switch system includes an optical position sensor using optical coupling to insure the integrity of isolation on the 12V to 24V master switch to allow for a safe and effective operation, and configured so that the microcontroller unit reads the position on the master switch.

A vehicle battery jump starter that is powered by a removable and rechargeable battery pack, such as a battery pack used with various hand-held power tools. The battery pack removably connects to a vehicle battery jump starter and can be selectively used to charge a power boost module within the vehicle battery jump starter. The power boost module includes, for example, a plurality of supercapacitors or lithium polymer battery cells. The power boost module in combination with the battery pack 100 can be used to jump start a vehicle battery.

A rechargeable battery jump starting device having a highly conductive electrical pathway from a rechargeable battery of the device to a vehicle battery being jump started. The highly conductive pathway can be provided by a highly electrically conductive frame connecting one or more batteries of the rechargeable battery jump starting device to battery clamps of the rechargeable battery jump starting device.

A rechargeable battery jump starting device with a leapfrog charging system. The leapfrog charging system, for example, can sequentially charge multiple batteries of the rechargeable battery jump starting device.
