[Abstract] As long as you pay attention to these points, the lithium battery life of electric bicycles can be doubled!

 

In recent years, with the advancement of lithium battery technology and the reduction of production cost, lithium battery electric bikes with lithium battery as the main power source have also flown into the homes of ordinary people. Compared with traditional lead-acid batteries, lithium batteries have light weight and cycle life. Long, high energy density, fast charging and so on. Most of the lithium battery life is designed around 1000 times (ordinary ternary lithium battery material), which is 3-4 years. But this does not mean that after 3-4 years of use, the life of the lithium battery is terminated. As long as you pay attention to these points, the lithium battery life of the e-bike can be doubled!

Take the ternary lithium battery as an example. The mainstream manufacturer produces 18650 batteries of lithium batteries. The main characteristics are high energy density, high cycle life and moderate manufacturing cost, but the requirements for the use environment and charging are relatively high.

1. Lithium batteries are afraid of heat and cold. Do not use them in extreme environments.

In summer, many people like to put lithium battery electric bikes under the sun, or stop in the yard or on the road in winter. This is very unfavorable for the service life of lithium batteries. The migration of lithium ions in electrolytes and electrode sheets The rate is closely related to temperature. In theory, the temperature can be used normally between -20 °C and 55 °C. In daily life, the lithium battery is used at a temperature between 5 °C and 35 °C. Users in the north should take the lithium battery home for storage in the winter, do not put it outdoors, and users in the south avoid summer exposure outdoors long time.

2. lithium batteries do not often deep charge and discharge

Many people think that the number of times of charging the lithium battery on the electric bicycle manual is as long as it is used once. It is a misunderstanding. The manual refers to the number of times of complete re-discharge. The lithium battery is different from the nickel-cadmium battery. Lithium battery does not have any memory effect, it can be charged anytime and anywhere. When the battery has residual power, charging will not shorten the service life, but also maintain the battery and prolong its cycle. For lithium batteries, the correct way is The lithium battery is charged when there is still power.

3. you should use a suitable charger to charge, avoid high current

The chemical activity of lithium batteries is much more active than lead-acid batteries. The requirements for chargers are higher. Once a brand-name charger or a fast charger that is not suitable is used, it not only affects the service life of the lithium battery itself, but also seriously overheats. An explosion occurs due to a broken short circuit of the diaphragm.

In addition, the 18650 battery is a 3C discharge, and your ebike is 8000W. The battery used is lower than the discharge current of your electric vehicle. This will cause the lithium battery to overheat, the current is too large and the life is shortened, and the drum kit will be scrapped. If your electric bike is very powerful and very fast, it is recommended to choose 18650 batteries with 10C current, so choosing the right battery is obviously very important!

4. do not “full charge” “overcharge” lithium battery


After many users buy the electric bicycyle lithium battery home, they still follow the method of using lead-acid batteries. The first three times to charge the lithium battery for 10-12 hours, They think the lithium battery needs to be activated, in fact, this is very affecting the life of the lithium battery. Some people think that it is correct to continue charging for another hour after the electric bicycle is fully charged to offset the interference of internal resistance . In fact, the practice is wrong. The correct approach should be to fully unplug the power supply when it is fully charged. The lithium battery of the electric bicycles should not be charged overnight, and it is prone to fire.

5. do not need to be fully charged  long storage time without using

 

When the electric vehicle lithium battery (18650 battery) is bought, it is generally 2-3 grids, and there is very little full power. The long storage time of the full battery will reduce the capacity of the lithium battery.  In addition, it is also necessary to pay attention to the selection of a better quality protection board. Pay attention to these points, your electric car lithium battery will be no problem for five or six years.

6. Hot-selling electric bicycle battery in 2019


(1) Lithium-ion hidden battery( 36V or 48v)

36V 10AH Lithium-ion battery specifically designed for HOTEBIKE electric bike A6AH26. The battery is designed to be put into the frame, making the bike look like a normal mountain bike without battery. With high capacity and low internal resistance, you can charge and discharge the battery at any time.
Easy to install and remove. The battery uses high-tech lithium technology, with waterproof design, long cycle life, small size and light weight. Easy to transport and safe to use.
With stable performance, the battery can be charged and discharged for about 800 times. Charging time: 4-6 hours. Motor power: 250 – 350W.
The battery will be promptly charged, the suggested charging voltage for 36V battery is 42V. Do not over-discharge the battery, over-discharge will harm the battery badly. For 36V battery, the discharge voltage should not be lower than 30V.

(2) Lithium-ion bottle battery936V or 48V)
