Problems solved by technology

It is generally used for the drive of pure electric vehicles, but its cycle life is short, charging and discharging are slow, and the power required for starting and accelerating the motor requires a sharp discharge process. With the smooth operation of the motor, the battery The output power will gradually remain stable. Due to the characteristics of the battery itself, the life of the battery will be greatly reduced if the battery repeatedly transmits high-power pulses. This discharge method will seriously affect the life of the battery.

Abstract

The invention discloses an intelligent power supply system for a new energy automobile. The intelligent power supply system comprises a power battery, a super-capacitor, a DC / DC (Direct Current / Direct Current) power converter and a motor, wherein the power battery is connected with the DC / DC power converter; the DC / DC power converter is connected with the motor; the battery is connected with the DC / DC power converter; and the motor is a dual-winding motor. According to the technical scheme of the invention, two kinds of power supplies are combined, the advantages of the two kinds of power supplies are brought into full play, and the power supplies are applied to a power supply system of a pure electric automobile, so that complete and continuous power supply is provided while a power supply source is protected.

Description

technical field [0001] The invention relates to the technical field of automobile power management systems, in particular to an intelligent power supply system for new energy vehicles. Background technique [0002] With the improvement of people's environmental awareness, traditional fuel vehicles are gradually replaced by energy-saving and new energy vehicles. Energy-saving and new energy vehicles generally refer to hybrid vehicles and pure electric vehicles. No matter what kind of vehicle, its basic drive structure includes a power supply and the driving motor, and the power supply is used to supply power to the driving motor through a certain control device, so as to provide all or part of the driving force for the vehicle. Traditional hybrid vehicles and pure electric vehicles generally use a single power source, that is, power batteries or super capacitors, which are suitable for different systems because of their respective advantages and disadvantages. Supercapacitor...
