Electric bicycle, refers to the battery as auxiliary energy in the ordinary bicycle on the basis of the installation of motor, controller, battery, switch brake and other control parts and display instrument system of electromechanical integration of personal vehicles. 2013 "China electric bicycle Industry innovation Summit Forum" data show that the number of Electric bicycles in China by 2013 broke through 200 million, and has been in the controversy of the electric bicycle "new NATIONAL standard" will also be introduced. The new standard is expected to revolutionize the e-bike industry. Main components of The charger A charger is a device for supplementing power to the battery. It is generally divided into two stages of charging mode and three stages of charging mode. Two-stage charging mode: constant voltage charging at first, charging current gradually decreases with the rise of battery voltage, and when the battery power is replenalized to a certain extent, the battery voltage will rise to the set value of the charger, and then it will be converted to trickle charging. Three-stage charging mode: at the beginning of charging, constant current charging is carried out to rapidly replenish the battery energy; When the battery voltage rises, the battery is charged at constant voltage. At this time, the battery energy is slowly replenished and the battery voltage continues to rise. When the charging termination voltage of the charger is reached, it will turn to trickle charging to maintain the battery and supply the self-discharging current of the battery. The battery Battery is the onboard energy that provides electric vehicle energy, electric vehicle mainly uses lead acid battery combination. In addition, nickel metal hydride batteries and lithium ion batteries have also been used in some light folding electric cars. Use tips: the controller main control board for the electric car owner circuit, with a large working current, will send out a large heat. Therefore, the electric car do not park in the sun exposure, also do not get wet for a long time, so as not to controller failure. The controller The controller is the part that controls the motor speed, and is also the core of the electric vehicle system. It has the function of undervoltage, current limiting or overcurrent protection. Intelligent controller also has a variety of riding modes and vehicle electrical components self-inspection function. Controller is the core component of electric vehicle energy management and various control signal processing. Turn handle, brake handle Handle, brake handle, etc. are the signal input components of the controller. The handle signal is the driving signal of electric vehicle motor rotation. Brake signal is when the electric car brake, brake the internal electronic circuit output to the controller of an electrical signal; After the controller receives this signal, it will cut off the power supply to the motor, so as to achieve the brake power off function. Booster sensor Bicycle moment sensor Power sensor is a device that detects pedal force and pedal speed signal when the electric vehicle is in power state. According to the electric drive power, the controller can automatically match the manpower and power to drive the electric car to rotate. The most popular power sensor is the axial bilateral torque sensor, which can collect the left and right side of the pedal force, and adopts non-contact electromagnetic signal acquisition mode, thus improving the accuracy and reliability of signal acquisition. The motor The most important part of the electric bicycle is the motor, the motor of an electric bicycle basically determines the performance and grade of the car. Most motors used by electric bicycles are high-efficiency rare earth permanent magnet motors, which are mainly divided into three types: high-speed brush-tooth + wheel reducer motor, low-speed brush-tooth motor and low-speed brushless motor. A motor is a component that converts battery energy into mechanical energy and drives electric wheels to spin. There are many kinds of motors used in electric vehicles, such as mechanical structure, speed range and electrification form. The common ones are: brush with gear hub motor, brush without gear hub motor, brush without gear hub motor, brush without gear hub motor, high disk motor, side hanging motor, etc. Lamps and instruments Lamps and instruments are the components that provide lighting and display the status of electric vehicles. The instrument generally provides battery voltage display, vehicle speed display, riding status display, lamp status display, etc. Intelligent instrument can also show the fault of the vehicle electrical components. Common structure Most electric bicycles use hub-type motors to directly drive the front or rear wheels to rotate. These hub-type motors are matched with wheels of different wheel diameters according to different output speeds to drive the whole vehicle, with a speed up to 20km/h. Although these electric cars have different shapes and battery placement, their driving and control principles are common. This kind of electric bike is the mainstream of electric bike products. Electric bicycle of special construction A small number of electric vehicles are driven by non-hub motors. These electric vehicles use side - mounted or cylindrical motor, middle - mounted motor, friction tire motor. The general use of this motor driven electric vehicle, its vehicle weight will be reduced, motor efficiency is lower than the hub efficiency. With the same battery power, a car using these motors will typically have a 5%-10% shorter range than a hub-type car.
