An electric vehicle with magnetic induction power generating device includes an vehicle body, at least one battery pack installed inside the vehicle body, at least one power generation device electrically coupled to the at least one battery pack for providing electricity, a transmission device placed between the battery pack and the power generating device, and at least one motor for driving the electric vehicle, wherein the at least one power generating device can be coupled to at least one free-running wheel of the vehicle for converting a rotating energy of the at least one free-running wheel into electricity.

The present invention is an electric vehicle wherein the vehicle is powered by an internal generator rather than the traditional method of plugging in to charge the electric battery. The internal generator is made up of an alternator and a regulator which control the flow of electricity to the battery of the car. The battery of the car will only need to be charged once at the beginning of use or first time use of the vehicle and then will obtain power from the internal generator.

An energy and supply system includes a switching device, a battery detection device, a speed detection device, a processing device, a main storage battery and a backup storage battery. Using the speed detection device, the processing device determines whether the driving speed of the vehicle exceeds a preset speed threshold, or it determines whether the rotation speed of the engine exceeds a preset rotation speed. The processing device uses the battery detection device to determine whether the main battery capacity is greater than the preset capacity. If the processing device determines that the driving speed of the vehicle exceeds a preset speed threshold, or it determines that the rotation speed of the engine exceeds a preset rotation speed, and it determines that the main battery capacity is greater than the preset capacity, the processing device controls the switching device.

A drive system comprises a DC-DC converter that is arranged to receive an input voltage from a battery having a nominal battery voltage. The DC-DC converter has a first mode of operation in which the DC-DC converter generates a regulated output voltage from the input voltage and supplies the regulated output voltage to a load, and a second mode of operation in which the DC-DC converter is by-passed such that the input voltage from the battery is supplied to the load. A controller is arranged to compare the input voltage to a threshold voltage that is less than the nominal battery voltage. The controller operates the DC-DC converter in the first mode when the input voltage is less than the threshold voltage, and operates the DC-DC converter otherwise.

Disclosed is a system for dramatically increasing the capacity of onboard power source through internal electricity generation. The internal electricity generation is accomplished using a propulsion device connected to a shaft. A shaft contains wire winding on its opposite end that are embedded within a stator winding. Thus, the motion of the propulsion device create the rotation necessary to create current within the stator and enables an onboard power source to be recharged therefrom.

An automotive power supply device includes first and second batteries, first and second load groups, a plurality of fuses interposed between the first and second batteries and the first and second load groups, and instantaneous interruption prevention devices. First and second redundant system loads that complement operation of each other are allocated to the first and second load groups. The instantaneous interruption prevention devices are connected to the first and second load groups, and prevent an instantaneous interruption of electric power supplied to at least any of the first and second load groups when one or more fuses are blown.

A battery charging system of an electronic device includes: a battery having a first nominal voltage and including: battery cells each having a second nominal voltage that is less than the first nominal voltage; and electrical connectors that electrically connect ones of the battery cells to provide the battery with the first nominal voltage; a first charge port configured to electrically connect to a first type of connector; a charging module configured to: receive power via the first charge port; and when a voltage of the received power is less than the first nominal voltage at least one of: charge ones of the battery cells individually; and charge groups of two or more of the battery cells.

A riding lawn mower comprising, a pair of rear drive wheels, a pair of front wheels, a deck positioned between the pair of front wheels and the pair of rear drive wheels, a rotatable cutting blade, and multiple battery packs removably coupled to the riding lawn mower and structured to provide power to the riding lawn mower, each battery pack graspable and removable by a user, wherein the multiple battery packs sequentially provide power to the riding lawn mower.

A 12 volt automotive battery system includes a first battery coupled to an electrical system, in which the first battery include a first battery chemistry, and a second battery coupled in parallel with the first battery and selectively coupled to the electrical system via a first switch, in which the second battery includes a second battery chemistry that has a higher coulombic efficiency than the first battery chemistry. The first switch couples the second battery to the electrical system during regenerative braking to enable the second battery to capture a majority of the power generated during regenerative braking. The 12 volt automotive battery system further includes a variable voltage alternator that outputs a first voltage during regenerative braking to charge the second battery and a second voltage otherwise, in which the first voltage is higher than the second voltage.

One embodiment is a system comprising an internal combustion engine including an output shaft, a pulley system structured to be driven by the output shaft, a first alternator and a second alternator structured to be driven by the pulley system, and an electromagnetic clutch integrated within one of the pulley system, the first alternator and the second alternator and structured to selectably couple and decouple at least one of the first alternator and the second alternator from the output shaft. The system includes a controller in operative communication with the internal combustion engine system and structured to evaluate power demand and power production capability parameters of the system and to control the electromagnetic clutch to engage or disengage in response to the evaluation.
