Lithium Battery Electric Bicycle

Lithium battery electric bicycle refers to an electric bicycle that uses lithium batteries as an auxiliary energy source. It is equipped with electromechanical integrated personal vehicles such as motors, controllers, batteries, steering handles and other control components and display instrument systems.

The main components

charger

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.

battery

The battery is the on-board energy that provides the energy of the electric vehicle. The lithium battery electric vehicle uses the latest lithium-ion battery.

Usage Tip: The main control board of the controller is the main circuit of the electric vehicle, 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 easiest way to detect the battery: 5A discharge, the voltage is lower than 12.63 in 30 seconds, the first 3 minutes of voltage does not fall and rise, the more the counter-lift, the better the quality.

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.

Turn, 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.

Power sensor

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.

Motor

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. Most of the motors used in today's electric bicycles are high-efficiency rare earth permanent magnet motors, which are mainly divided into high-speed brush + gear reduction motors, low-speed brush motors and low-speed brushless motors. At present, the performance of high-speed brush + gear reduction motors is the most. Good, the price is also expensive; low-speed brush motor is cheaper, but the performance is worse; brushless motor because of the high quality requirements of the controller, there are not many brands listed, the average consumer should choose the brand when buying.

(Neda Lithium Electric Bicycles) We know that electric bicycles (hereinafter referred to as electric vehicles) use electric energy such as batteries and lithium batteries as auxiliary energy, and have two wheels, which can realize human riding, electric or electric assist. Functional special bike.

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.
