electric vehicle bike conversion kit

Many electric car ride out of the public found that electric cars riding riding the sudden, "strike." By the impact of heavy rain a few days ago, a lot of electric cars last "get together" maintenance.

Reporters this investigation found that many service points one day repair a dozen, and mostly replace the controller, a controller in the hundreds of hundred or even several hundred dollars of the price, so many people puzzled.

Electric car "get together" repair shop

"Riding riding, first burst of roaring to ring, suddenly strike." Yesterday, Ms Wong reflect the public said that he went out, electric cars and without any exception, I did not expect was soon riding, riding fixed on the the.

Ms Wong said that not only is she a person, to repair, there were more than a dozen people "get together" repair shop repair electric cars. After receiving the reflected, reporters rushed to Ms. Huang repair point where six or seven to wait for the maintenance of the public that electric vehicles, mostly riding rode on the "strike".

"I pushed for three miles, to find a repair shop, make a half-day off to repair." Cheng said the people, his family three bike conversion kit, all to a "strike" symptoms, electricity can also be connected, is driven not. In the service point, to repair the public said that in a few days ago the rain, their car in heavy rain from deep water through.


Controller in the end how much value?

At noon yesterday, the reporter went to several other urban electric vehicle maintenance point that, "get together" maintenance of electric cars is widespread. Mr. Du said the people, he was controller of the electric car burn water, not only to push this to the warranty.

Reporters found that waiting for the public service bike conversion kit, 80% are waiting for replacement controller. "Are due to heavy rains, the water controller burned out." Maintenance point boss said, "controller generally not bad, and only water, and was easily broken."

Interview, many people complained that as long as the replacement controller, repair shop owner asking price easily one hundred fifty-six, or even two hundred or more.

"In recent days, I one day want to change a dozen, but not when the storm, put on a few months also rare." A repair shop owner, said, controller devices are the main bike conversion kit, you can not bad riding, but also a storm broke, and many do not warranty, normal to high prices, want to earn more.

bike conversion kit controller worth in the end? Asked several repair shop owners are tight-lipped. After shopping platform Taobao and other reporters in the search found more than 500 watts are the eight ninety yuan, 24V and 36V, more cheaper, but some of the genuine original asking price is higher.

Many online sellers said that the maintenance shop is unlikely to replace the original authentic brand of electric cars, some more common type, the price is not expensive to go.

Hub motor engine composition and structure

Hub motor engine composition and structure

The engine is a machine capable of transforming a source of energy, which may be in chemical form (in the presence of a fuel), electrical or thermal energy, mechanical energy or work in a continuous mechanical (devices capable of this transformation so impulsive and discontinuous are called actuators, piezoelectric muscles, valves, relays, etc..).

In a philosophical sense, a hub motor is the body that causes the movement or change in other affiliated institutions: Aristotle spoke of "unmoved mover", a term taken up by other philosophers, to indicate the cause of the universe, ie the 'object or person (according to his philosophy) was the principle.

Engine is also used in computer science (graphics engine, search engine, database engine ...) to describe a program that "transformed" into something else something automatically and continuously. More precisely in an engine is a computer program that, in the course of its normal operation:

1.You never ends, unless you have technical problems or who is not deliberately stopped;
2.Develop its output from a set of data and / or default procedures;
3.E intended to be used by other programs and not directly by humans

All physical real engines of any kind may be, are subject to the laws of thermodynamics, this means all work will provide a lower total energy contained in the fuel spent on their operation. The relationship between the work supplied and the energy expended by a particular motor is its gross return, including the fraction of energy spent on the inner workings of the engine. It is always lower than the thermodynamic efficiency, performance (not measured, but calculated) for the same engine considered "ideal", ie no internal energy dissipation.

In particular, the efficiency of internal combustion engines depends critically on the initial temperature and end of their cycle, and for a given temperature drop ÎŽT will be smaller than that of the Carnot cycle in the same ÎŽT.

The most commonly used engines are alternatives and / or rotary, and produce work in the form of a torque or a force on an axis; others produce only a linear force.

What is a Bike conversion kit?

How about if we tell you that you can turn your bike into an electric one?
Bike conversion kit With this is possible and you can enjoy the benefits of pedal assist electric bike.

If you have a bike for a while but it costs too much effort to climb the slopes, then the conversion kit option might be a good solution to keep you on your bike and do not change the car. The kits are suitable for all types of bicycles, folding, mountain, or walk.

What is a Bike conversion kit?
The kit is basically a motor, a battery and controller / switchgear.

How it works

 The engine is at the front wheel. Depending on the battery, that you can hang from the handlebar, frame or carried in the carrier. When you turn the engine does not have to do much effort to pedal (pedal assist).

Are the batteries and motor are great?
¿Weigh many kilos?
The engine is mounted on the front wheel to the hub and is not very large. The size of the battery may vary depending on the battery. A lead-acid battery is larger and it weighs much more than a battery. So you'll notice the price difference between one type of baterĂșa another.

The Lithium polymer usually has a quite small with a weight of only 2 to 3 kgs. The lead are bigger and weigh between 11 and 20kgs (depending on manufacturer / brand)

Did I can mount it myself?
A minimum of skill with bicycles and tools to install power kit and power lines cut and paste in case you have to elongation. If you've never messed with your bike, visit a professional mejoir.

And what's with the switchgear?
The emergency switch (usually or always should come) is a vital safety feature to cut the power directly from its source, the battery. In case of damage or loss of control of the system, the switch ensures our integrity.

What kind of kit for me?
If you ride a bike you might opt ​​for a drum kit made of lead. But if you have a folding bike, no doubt, you should opt for a lithium battery. If not, the battery will be heavier than your folding. But the truth is that, although usually more expensive lithium battery, is preferable. A battery pack can weigh between 5-9 pounds, and thus did not gain too much weight to your bike.

Electric bike conversion kit

Turn your conventional bike into "electrical" pedal-assisted electric equipment of high quality and well made ​​long journeys with much less effort and while exercising.

  Electric bike conversion kit composed of high quality 250W wheelers (not including the tire), Lithium Battery with BMS (Battery Management System), pedal sensor, selector switch on the level of assistance, wiring and battery charger.

BLDC motor controller by the converter

BLDC motor working principle

     BLDC motor controller, including the Ministry of Power and Control Division as below: Power Ministry to provide three-phase power to the motor, control by the Ministry of the demand for converting the input power frequency. Department of directly to the DC power input (typically 24V) or AC (110V/220 V), if we have to first AC input is converted to DC by the converter. Either DC or AC input to input into the motor coil will be required before the DC voltage converted by the inverter 3-phase voltage to drive the motor. Inverter is generally composed of six power transistors. Six power transistors connected to the motor, as the control flow through the motor coil switch.

    Make the motor turn up, the Ministry must first control the Hall IC to the motor rotor current location, then the stator winding in accordance with the decision on (or off) power transistor converter in order, so that current flows through the sequence motor coil forward (or reverse) rotating magnetic field, and interaction with the rotor magnet, so you can make the motor clockwise / counterclockwise rotation. When the rotor rotation to another group of Hall IC signal out of position, control of the Department again on the next set of power transistors, and so the motor can continue to rotate the same direction until the control of the Ministry decided to stop the rotor is shut down power transistor ; to reverse the rotor power transistor on the opposite order.

BLDC motor is a rotary machine

BLDC motor is a rotary machine, it will transform electrical energy into mechanical energy, which includes a solenoid winding to generate magnetic fields, or distribution of the stator windings and a rotating armature or rotor, a current through the wire and the magnetic field leaving the role of rotation, some types of these machines can be used for motors, generators can be used.

BLDC motor controller is to convert electrical energy into mechanical energy of the equipment, it is the use of power by the force coil in a magnetic field the phenomenon of rotation is made, distributed to each user at, BLDC motor power by using a different DC motor and AC motor into the power system Most of the motor AC motor, which can be synchronous or asynchronous motor motor (stator magnetic field speed and rotor speed is not in sync speed). Mainly by the motor stator and rotor components. Power wire in the magnetic field direction of movement by force and magnetic sense of direction with the current line (the magnetic field direction) direction of the. Motor works by magnetic force on the current role of the motor rotation.
