Abstract: An electric vehicle (EV) charging station for fast charging (e.g. 5 to 15 minutes) an electric vehicle (EV). The EV charging station can be configured to charge multiple EVs and multiple conventional vehicles at the same time. The EV charging station can include a power source, an electric reservoir receiving power from the power source, an AC to DC power converter for receiving AC power from the power source and converting the AC power to DC power for supplying DC power to the electric reservoir, an EV charger receiving DC power from the electric reservoir; and a first DC to DC converter receiving DC power from the electrical reservoir and converting the DC power to DC power suitable for charging the electrical vehicle.

Abstract: A battery, for example, a rechargeable battery (e.g. lithium ion battery) having a casing with battery terminals. The casing, for example, includes an upper section, middle section, and lower section connected together. The battery can be connected to one or more battery trays having the same height or different heights for various applications.

Abstract: 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.

Abstract: A rechargeable battery jump starting device and a battery frame for use in an electronic device such as a portable rechargeable battery jump starting device. The rechargeable battery jump starting device maximizes the power conducted from the rechargeable battery to a battery being jump started.

Abstract: A rechargeable battery jump starting device having detachable positive and negative cables. The rechargeable battery jump starting device, including a rechargeable battery connected to a positive cam-lock cable connecting device and a negative cam-lock cable connecting device. The rechargeable battery jump starting device can include a highly electrically conductive frame connecting the rechargeable battery to the cam-lock cable devices.

Abstract: Provided is a method of charging a deeply discharged battery using a battery charging device, the method including measuring the output voltage of the deeply discharged battery using the battery charging device, and if the output voltage is at or near zero (0) volts, charging the deeply discharged battery using the battery charging device in a forced mode.

Abstract: Provided is a jump starting device for charging a depleted discharge battery, the device includes a rechargeable battery having a positive terminal and negative terminal; a switch comprising a jump start current sharing circuit electrically connected to the rechargeable battery; and a battery clamp electrically connected to the jump start current sharing circuit.
