Introduction to lithium batteries for electric bicycles

With the progress of science and technology and the strengthening of the concept of environmental protection, electric bicycles are more and more favored by people.

The core component of electric bicycle is lithium battery, which directly affects the performance and safety of the vehicle. In this article, we will introduce the maintenance methods and techniques of lithium batteries for e-bikes in detail.

Introduction of lithium battery for electric bicycle

E-bike lithium battery consists of positive electrode material, negative electrode material, electrolyte and diaphragm. The positive electrode material is mainly lithium ternary and lithium manganate. Negative electrode materials are mainly graphite and lithium titanate.lithium ion battery VS lead acid battery The electrolyte is a mixture of dissolved salt and organic solvent; the diaphragm is a film used to separate the anode and cathode materials.

The basic principle of the work of lithium batteries for electric bicycles is mainly that the storage and release of corporate electrical energy can be achieved by improving the migration of lithium ions between the positive and negative materials.

When the battery is charging, lithium ions escape from the cathode material and migrate to the anode material through the electrolyte and diaphragm; when the battery is discharging, lithium ions escape from the anode material and return to the cathode material through the electrolyte and diaphragm.

Second, lithium e-bike battery maintenance methods

1、Correct charging

The charging method of lithium e-bike battery directly affects the service life of the battery. It is recommended to use the original charger to charge the battery to avoid damage caused by overcharging. At the same time, the principle of "shallow charging and discharging" should be followed to avoid over-charging or over-discharging the battery.

2, maintain the appropriate temperature

High and low temperatures will have a negative impact on the lithium e-bike battery. High temperature will accelerate the aging of the battery and capacity degradation, while low temperature will reduce the battery charging and discharging performance. Therefore, it is necessary to avoid using e-bikes in high and low temperatures.

3、Regular inspection

Regularly check the appearance of the lithium battery of the e-bike, the connecting wires and the battery pack, etc., to ensure that the battery pack and all parts are intact. If abnormalities are found, they should be dealt with in a timely and effective manner to avoid the problem from expanding.

4, avoid severe vibration

Strong vibration will have an adverse effect on the lithium battery of the e-bike, which will easily cause damage to the internal diaphragm and positive and negative materials of the battery, thus affecting the performance and service life of the battery. Therefore, in order to avoid riding an e-bike on a bumpy road, try to choose a flat road to drive.

Third, the use of lithium e-bike battery skills

1、Acceleration and braking

During driving, rapid acceleration and braking should be avoided as much as possible, which will lead to increased battery current fluctuations, thus affecting the service life of the battery. In order to extend battery life, it is recommended to use smooth acceleration and braking.

2、Adjust the driving mode

The driving modes of the e-bike include economy mode, standard mode and sport mode.lithium battery vs lead acid The economic mode has the longest driving distance but slower speed; the driving performance and range in the standard mode are relatively balanced; the sport mode has the fastest driving speed but the worst range. Therefore, the appropriate driving mode should be selected according to different usage scenarios.

3、Avoid overloading

Overloading will lead to the weight of our e-bikes can be increased, thus constantly increasing the burden on the battery, affecting the life of the battery. Therefore, overloading should be avoided as well as occurring.

Fourth, summarize

E-bike lithium battery maintenance and use skills are directly related to the performance and service life of the lithium battery. Correct charging method, appropriate temperature, regular inspection, avoid violent vibration and other maintenance measures can effectively extend the service life of the battery.

At the same time, reasonable use of power assist, adjust the driving mode and other skills can also help us better play the performance of the battery. By understanding and mastering these maintenance and use techniques, we can better enjoy the convenience and environmental advantages of e-bikes.
