What is Li-ion battery electric bicycle？
Li-ion battery electric bicycle is an electric bicycle that uses Li-ion battery as an auxiliary energy source, and it is a mechatronic personal transportation system that is equipped with motor, controller, battery, handlebar gate and other manipulation parts and display instrumentation system.https://www.hotebike.com/
Composition of Li-ion battery electric bicycle
The battery is the accompanying energy source that provides the energy of the bicycle, and the Li-ion battery electric bicycle uses the latest type of lithium-ion battery. Tips for use: Do not park the electric bicycle under the sun, and do not get wet for a long time to avoid controller failure.

Easy to charge it separately
The charger is a device to replenish the battery’s electrical energy, generally divided into two stages charging mode and three stages mode. Two-stage charging mode: first constant voltage charging, charging current gradually decreases with the rise of battery voltage, after the battery power replenishment to a certain degree, the battery voltage will rise to the charger’s set value, then it is converted to trickle charging. Three-stage charging mode: when charging starts, constant current charging first, quickly replenish energy to the battery; wait for the battery voltage to rise and then switch to constant voltage charging, when the battery energy slowly replenishes, the battery voltage continues to rise; when it reaches the charger’s charging termination voltage value, switch to trickle charging to maintain the battery and supply the battery self-discharge current.
The controller is the component that controls the motor speed and is the core of the electric system of the electric bike, with under-voltage, current-limiting or over-current protection functions. The intelligent controller also has a variety of riding modes and self-test function for the whole electric parts of the vehicle. The controller is the core component of electric bike energy management and various control signal processing.

Turnbuckle, gate, etc. are the signal input parts of the controller. The turn signal is the driving signal of the electric car motor rotation. The gate signal is an electrical signal output to the controller from the electronic circuit inside the gate when the electric car brakes; after the controller receives this signal, it will cut off the power supply to the motor, so as to realize the brake power-off function.
The power sensor is a device that detects the cycling pedal force back to the pedal speed signal when the electric bike is in the power-assisted state. Controller according to the electric drive power, in order to achieve automatic matching of human power and electric power, together to drive the electric car rotation.
The most important accessory of an electric bicycle is the motor, and the motor of an electric bicycle basically determines the performance and grade of the vehicle. 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 reducer motor, low-speed brush motor and low-speed brushless motor three, at present, high-speed brush + gear reducer motor performance is the best, the price is also expensive; low-speed brush motor to be cheaper, but the performance is worse; brushless motor due to the controller quality requirements are extremely high, not many brands listed, ordinary Consumers are best to pick the brand when buying.
Lamps and meters part is the combination of components that provide lighting and display the status of electric vehicles. The meter generally provides battery voltage display, whole vehicle speed display, riding status display, lamp status display, etc. The intelligent meter can also display the fault condition of each electrical component of the whole ebike.

What are the advantages and disadvantages of Li-ion battery electric bicycle.
The biggest advantage of Li-ion battery electric bicycle is the longevity. The global Li-ion battery price is expensive just to see the appearance, in fact, careful calculation of the cost and lead-acid battery is about the same, now the general Li-ion battery warranty 2 years, lead-acid battery warranty 1 year.
In the use of Li-ion batteries should be noted that the battery is placed for a period of time into a dormant state, when the capacity is lower than normal, the use of time is shortened. But the Li-ion battery is easy to activate, only after 3-5 normal charge and discharge cycle can activate the battery, recovery of normal capacity. Because of the characteristics of the Li-ion battery itself, it is almost no recall effect. Therefore, users of new Li-ion batteries in the activation process, is not the need for special methods and equipment.
Now the price of Li-ion battery electric bicycle is generally several hundred to one thousand yuan higher than the lead-acid battery electric bicycle, so it is difficult to get the recognition of customer customers in the market. Li-ion battery is light, environmentally friendly, and will not produce environmental pollution after disposal. Once the application technology becomes sophisticated and the sales volume increases, the price of Li-ion battery electric bicycle will come down.
Li-ion battery charging time should not be too long. Li-ion battery or charger will automatically stop charging after the battery is full, and there is no nickel charger called “trickle” charging that lasts more than 10 hours. That is to say, if your Li-ion battery is full, put on the charger is also a white charge. And we can not ensure that the characteristics of the battery’s charge and discharge maintenance circuit never change and quality of full assurance, so your battery will be a long time in the edge of risk wandering. This is another reason why we are against long charging.
