The Main Parts Of Electric Bicycles May 27, 2017

 Electric Bike Electric bicycle is the main components of electric bicycles refers to the battery as a supplementary energy on the basis of ordinary bicycles, the installation of the motor, controller, battery, handle and other control parts and display instrumentation system of mechanical and electrical integration of personal transport ; 2013 "China Electric Bicycle Industry Innovation Summit Forum" data show that China's electric bicycles cut through the 2013 volume of 200 million, and has been in dispute in the electric bike "new national standard" will also be introduced. The new national standard is expected to set off a big change in the electric bicycle industry.

  The main components

  Electric Bike Charger is to recharge the battery device, generally two-stage charging mode and three-stage mode two. Two-stage charging mode: the first constant voltage charging, charging current with the battery voltage rise gradually reduced, and other battery power to a certain extent, the battery voltage will rise to the charger set value, this time into trickle charge. Three-stage charging mode: the beginning of charging, the first constant current charging, and quickly add energy to the battery; such as battery voltage rise to constant voltage charging, this time the battery energy slowly added, the battery voltage continues to rise; to charge the charge termination voltage Value, to trickle charge to maintain the battery and supply the battery self-discharge current.

  Battery is to provide electric car energy of the car energy, electric vehicles mainly use lead-acid battery combination. In addition, nickel-metal hydride batteries and lithium-ion batteries have also been in some light folding electric cars began to use.

  Use Tip: Controller main control board for the electric car main circuit, with a large operating current, will issue a larger heat. Therefore, the electric car do not park in the sun exposure, do not rain for a long time, so as to avoid the controller failure.

  The controller is the component that controls the motor speed and is the core of the electric vehicle electrical system with undervoltage, current limiting or overcurrent protection. Intelligent controller also has a variety of riding patterns and vehicle electrical components self-test function. The controller is the core component of electric vehicle energy management and various control signal processing.

  The handle, handle, etc. is the signal input part of the controller. The turn signal is the driving signal of the electric motor rotation. Brake signal is when the electric car brake, the brake internal electronic circuit output to the controller of an electrical signal; controller to receive this signal, it will cut off the power supply to the motor, in order to achieve the brake power function.

  The booster sensor is a device that detects the speed of the pedal when the electric vehicle is in the assisting state. The controller according to the electric drive power,

  To achieve automatic matching of manpower and power, driving the electric car to rotate. At present, the most powerful power sensor is the central axis of the bilateral torque sensor, its product is characterized by the ability to capture the left and right sides of the pedal force, and the use of non-contact electromagnetic signal acquisition, thereby improving the signal acquisition accuracy and reliability.

  The most important part of the electric bicycle is the motor, an electric bicycle motor basically determines the performance and grade of the car. Electric bike used by the motor are mostly efficient rare earth permanent magnet motor, which is mainly divided into high-speed brush teeth + wheel motor, low-speed brush motor and low-speed brushless motor three.

  The motor is a component that converts the battery power to a mechanical energy that drives the electric wheel to rotate. In the electric car used in the motor, its mechanical structure, speed range and power form there are many kinds. Common are: a brush with a hub motor, brushless gear motor, brushless gearless motor, brushless gear motor, high disk motor, side hanging motor.

  Electric Bike The fixture, part of the meter is a combination of parts that provide illumination and display the state of the electric vehicle. Instrument generally provide battery voltage display, vehicle speed display, riding status display, lamp status display. Intelligent instrument can also show the vehicle electrical parts of the failure.

  Most electric bikes use wheel hub motors to drive the front wheels or rear wheels directly. These wheel-type motor according to the different output speed, respectively, with different wheels of the wheel with the drive to drive the vehicle, the speed of up to 20km / h. Although the shape of these electric cars and battery installation location is not the same, but its drive and control principles exist in common. This type of electric bicycle is the mainstream of electric car products.

  Special construction of electric bikes

  Electric Bike A small number of electric vehicles with non-hub motor drive. These electric cars use side-mounted or columnar motors, in the home motor, friction tire motor. General use of this motor-driven electric vehicles, the vehicle weight will be reduced, the motor efficiency is lower than the wheel-type efficiency. In the case of the same battery energy, the use of these motors will generally be less than the wheel-type vehicle continued mileage reduction of 5% -10%.
