The accessories required for assembling electric vehicles mainly include electric bike frame,electric bike casing, electric bike motor, electric bike controller, electric bike DC converter,electric bike wheel, electric bike battery, electric bike instrument, electric bike brake portion, Accessories such as lamps, rear view mirrors, etc.
The main components:
The charger is a device for replenishing the battery, and is generally divided into a two-stage charging mode and a three-stage mode. Two-stage charging mode: First, constant voltage charging, the charging current gradually decreases with the rise of the battery voltage. After the battery power is replenished to a certain extent, the battery voltage will rise to the set value of the charger, and at this time, it will be converted to trickle charging.Three-stage charging mode: When charging starts, the constant current is charged first, and the battery is quickly replenished; when the battery voltage rises, it is converted to constant voltage charging. At this time, the battery energy is slowly replenished, and the battery voltage continues to rise; the charging end voltage of the charger is reached. When the value is changed, it is switched to trickle charge to maintain the self-discharge current of the battery and the supply battery.
The battery is the on-board energy that provides the energy of the electric vehicle, and the electric vehicle mainly uses the lead-acid battery combination. In addition, nickel-metal hydride batteries and lithium-ion batteries have also been used on some portable folding electric vehicles.
Usage Tip: The main control board of the controller is the main circuit of the electric bikes, which has a large working current and will generate a large amount of heat. Therefore, do not park the electric vehicle in the sun, and do not expose it to rain for a long time to avoid malfunction of the controller.
The controller is the component that controls the speed of the motor and is the core of the electric system of the electric vehicle. It has undervoltage, current limiting or overcurrent protection. The intelligent controller also has a variety of riding modes and self-checking functions for vehicle electrical components. The controller is the core component of electric vehicle energy management and various control signal processing.
(4)Turn and Brake
The handle, the brake lever, etc. are the signal input components of the controller. The turn signal is a drive signal for the rotation of the electric vehicle motor. The brake lever signal is an electrical signal that the internal electronic circuit of the brake lever outputs to the controller when the electric vehicle brakes; after receiving the signal, the controller cuts off the power supply to the motor, thereby implementing the brake power-off function.
The booster sensor is a device that detects the riding pedal force back to the pedal speed signal when the electric vehicle is in the assist state. The controller automatically matches the manpower and electric power according to the electric driving power to jointly drive the electric vehicle to rotate. At present, the most powerful power-assisted sensor is a mid-axis bilateral torque sensor. Its product features are capable of collecting the pedaling forces on both sides, and adopts a non-contact electromagnetic signal acquisition method, thereby improving the accuracy and reliability of signal acquisition.
The most important accessory for an electric bicycle is the electric motor. The electric motor of an electric bicycle basically determines the performance and grade of the electric bicycle. The electric motors used in electric bicycles are mostly high-efficiency rare earth permanent magnet motors, among which there are three types of high-speed brushed teeth + wheel reducer motors, low-speed brush motors and low-speed brushless motors.
A motor is a component that converts battery power into mechanical energy and drives the electric wheel to rotate. There are many types of motors used in electric vehicles, such as the mechanical structure, the range of speeds, and the form of energization. Common ones are: brushed gear hub motor, brushless gearless hub motor, brushless gearless hub motor, brushless gear hub motor, high disk motor, side-mounted motor, etc.
A 350w motor.
A set of batteries.
Power switches and wires on electrical wiring.
Hardware that must be used when fixing.
STEP1 Handlebar and instrument panel installation:
STEP2 Wheel hub shock absorber installation
STEP3 Central foot pedal, transmission system, and outer plastic parts are fixed: the front wheel is installed in the middle of the frame, and the flat foot should be fixed with screws and wrenches first. Then install the drive gear and chain. The outer plastic parts should be lightly loaded, and the lights must be installed before the installation, and then the plastic parts should be loaded;
STEP4 Left decoration accessories assembly: front lights, brakes, mirrors, saddles, storage boxes, these accessories should also be slowly installed, these parts can be installed in any order, you need to pay attention to the card slot card In place, the wiring of the lights should be laid out;
Electric bike refer to the use of batteries as auxiliary energy on the basis of ordinary bikes, and the installation of motor, controller, battery, steering handles and other control components and display instrumentation system of mechatronics personal transport.According to data from the “China Electric Bicycle Industry Innovation Summit Forum” in 2013, China’s electric bikes have exceeded 200 million units in 2013, and the “new national standard” for electric bikes, which has been controversial, will also be introduced. The new national standard is expected to set off a major revolution in the electric bicycle industry.The initial stage of electric bikes is also known as the early experimental production phase of electric bicycles, in terms of time, from 1995 to 1999. This stage is mainly about the four major parts of electric bicycles, the key technology research of motor, battery, charger and controller.
