Description
Technical field
The utility model relates to a kind of Self-balance electric vehicle power supply based on super capacitor, particularly application of power and Self-balance electric vehicle field.
Background technology
Self-balance electric vehicle is a kind of new traffic tool, and it judges the posture state residing for vehicle body with built-in accurate solid-state gyroscope, and after calculating suitable instruction through central microprocessor that is accurate and high speed, CD-ROM drive motor accomplishes the effect balanced.Self-balance electric vehicle has obtained liking of a lot of trade company and individual since occurring commercially, this series products is in great demand in abroad, also obtain doting on of more and more beans vermicelli at home in recent years, the Self-balance electric vehicle having a satisfaction can bring unlimited enjoyment to you.A lot of people says that it is the junior partner of Almightiness type, and this type of walking-replacing tool is easy to carry, establishes close relation with people's travel activity.Shuttle back and forth between campus, move after meal, amusement and leisure or working, participate in significant club activities etc., it has all played great function.But the power supply of traditional Self-balance electric vehicle uses lead-acid storage battery or lithium cell, their shortcoming be battery life short, manufacture use that environmental protection cost is high, charging duration and can the number of times of recharge being still restricted.Ultracapacitor is compared with lead-acid storage battery and lithium cell, there is ultrashort charging duration, ultra-wide operating temperature, superelevation specific power, the unlimited advantage such as service life, energy-conserving and environment-protective, along with improving constantly of ultracapacitor specific energy, the Self-balance electric vehicle application of power based on super capacitor has a extensive future.
Summary of the invention
The utility model object is the deficiency in order to overcome lead-acid storage battery and lithium cell charging overlong time, proposes a kind of Self-balance electric vehicle power supply based on super capacitor.This power source charges time can shorten more than 10 times.Due to the high specific power of super capacitor, under the control action of this power supply, pose adjustment and climbing travel more smooth and easy.
The utility model comprises 8 component parts: ultracapacitor module, LM7924 Voltage stabilizing module, LMD18200 driver module, stepping motor, STM32F control module, MPU9250 sensing module, LM2576-3.3 Voltage stabilizing module, LM2576-5 Voltage stabilizing module.
The utility model solves the technical scheme that its technical matters adopts: utilize civil power to charge to super capacitor module at ordinary times.During Self-balance electric vehicle work, super capacitor module, through the 24V direct current (DC) of LM7924 Voltage stabilizing module stable output, is powered to LM18200 driver module, is made stepping motor.Super capacitor module is through the 5V direct current (DC) of LM2576-5 Voltage stabilizing module stable output simultaneously, powers to STM32F controller.LM2576-5 Voltage stabilizing module is powered to MPU9250 attitude sensing module through the 3.3V direct current (DC) of LM2576-3.3 Voltage stabilizing module stable output again simultaneously.When people stands on Self-balance electric vehicle, MPU9250 attitude sensor obtains corner information and acceleration information, and they are sent into STM32F control module, STM32F control module exports pwm control signal according to attitude information, give LM18200 driver module, produce new PWM drive singal, make the real-time acceleration and deceleration of stepping motor and rotating.
The beneficial effects of the utility model
One is the lithium ion battery that this power supply has been abandoned traditional lead-acid storage battery and risen in recent years, directly adopts bank of super capacitors as power supply, achieves this important breakthrough of the ultrafast accumulation of energy of Self-balance electric vehicle.Two is that this power supply topologies is simple, and directly or indirectly super capacitor output voltage is stabilized in 24V, 5V, 3.3V respectively for subsequent module by Voltage stabilizing module, reliability is high.
