Abstract

The invention discloses a simple and reliable electric vehicle extend range power supply system and extend range electric vehicle. A drive gear of the electric vehicle extend range power supply systemis coaxially and fixedly connected with a wheel axle of the electric vehicle, a driven gear is engaged with the drive gear, the driven gear is coaxially connected with an input shaft of a clutch, anoutput end of the clutch is connected with a low speed shaft of a speed increaser, a high speed shaft of the speed increaser is connected with a rotor shaft of a direct-current generator, a control end of a controller is electrically connected with the clutch to control connecting or disconnecting, and a power supply output terminal of the direct-current generator is electrically connected with astorage battery, or the power supply output terminal of the direct-current generator is electrically connected with the storage battery through the controller. The simple and reliable extend range electric vehicle comprises the simple and reliable electric vehicle extend range power supply system. According to the simple and reliable electric vehicle extend range power supply system and the extendrange electric vehicle, opening and closing of the clutch are controlled by the controller to convert the kinetic energy of wheels to direct current to directly charge the storage battery, and underthe condition of simplicity and reliability, the purpose of increasing endurance mileage with no pollution in an environmental protective mode is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a simple and reliable electric vehicle range-extending power supply system that can effectively increase the cruising range and is environmentally friendly and pollution-free, and the range-extending electric vehicle. Background technique [0002] An electric vehicle, that is, an electric drive vehicle, is a vehicle that uses a battery as an energy source, and converts electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. Electric vehicles include electric bicycles, electric motorcycles, electric tricycles, low-speed electric vehicles, etc. [0003] With the improvement of people's living standards and the formation of an energy-saving and environmentally-friendly social consensus, electric vehicles have been widely used as short-distance transportation tools due to their advant...

AI Technical Summary

Problems solved by technology

However, due to the limited driving range due to the battery capacity of the electric vehicle, most electric vehicles in the prior art can only be charged at fast charging devices on the street or at parking places, and often using the fast charging device to charge the battery will cause damage to the battery. damage, which shortens the service life of the battery, and the safe charging method at the parking place causes mileage anxiety due to the limitation of battery capacity

For this reason, in the prior art, there is also a brake feedback electric energy device installed in the electric vehicle to supplement the battery, but generally an alternator is used to connect with the wheel, or directly installed in the wheel, and the alternating current needs subsequent rectification, filtering and other processes , not only will reduce the energy conversion efficiency, but also the increased circuit will reduce the reliability of the system

In addition, since the feedback voltage during braking is generally relatively high, it will cause the on-board charging circuit and power supply circuit to be separated from the power supply system during braking, so that the battery of the electric vehicle can neither be charged continuously, nor can it realize normal driving power supply. come dangerous

In addition, although the built-in and in-wheel generators are compact in structure, they also have complex structures, high costs, and the status of being online at any time will also lead to rapid aging.

Due to the use of brake feedback power generation technology, it will not generate electricity when it is downhill or overspeed without braking. Not only is the charging method inflexible, and the range extension effect is not obvious, but also requires braking to slow down in the state of slight overspeed, although it is accompanied by some energy. recovery, but the recovery time is short and it will also cause wear of the brake pads
