For an electric bicycle, the correct charging method will be conducive to the extension of battery life, and the wrong charging method will not only shorten the service life of the battery but also have security risks.

Therefore, the following seven charging methods should be avoided when charging electric bicycles.

1. Mix different types of chargers for charging

Different brands and different models have different battery models. Naturally, chargers are different and cannot be used universally. However, some electric vehicle users often mix them up in the use process. For example, they charge 48V batteries with 60V chargers and 12Ah batteries with 20Ah chargers. If the charging voltage and current do not match, the batteries will be greatly damaged.

Correct Way: Use a special charger, try to use the original brand charger.

2. Charge the battery at high temperature

When the electric bicycle is riding, the battery itself will heat up. In addition to the high temperature in the weather, the temperature of the battery will often exceed 60 degrees. If the battery is charged at this time, it is easy to cause battery water loss, increase the risk of battery charging drums, and reduce the service life of the battery.

Correct Way: Put the electric bicycle for an hour, wait for the battery to cool down, and then recharge, which can protect the battery and prolong the service life of the battery.

3. Charging time

Generally, it does not take more than 8 hours to charge the batteries of electric bicycles. However, many ebike owners often charge all night for convenience, and the charging time is more than 12 hours, which often affects the battery life. Because the charging time is too long, it is likely to cause battery overcharge, and overcharge will harm the battery drum and affect battery life.

Correct Way: The charging time is kept within 8 hours, which can protect the battery and prolong its service life.

4. Carry the charger with you for charging

This kind of situation usually happens to the users who have a long distance to ride. Many users like to carry the charger with them for convenience. However, many small components in the charger are easy to fall off due to vibration, which will lead to battery damage during charging.

Correct Way: Choose an original charger and put it at the destination or keep it properly during carrying to avoid damage to the charger and prolong the service life of the battery.

5. Charging in the high-temperature environment with the sun

Because the battery of an electric bicycle will heat up in the process of charging, and if you choose to charge in the high-temperature environment with the sun, it is easy to cause the battery water loss, thus causing the battery charging drum, which will greatly reduce the battery life.

Correct Way: Choose to charge in the shade without sunlight, which can protect the battery and prolong its service life.

6. Purchase and use low-cost and low-quality chargers

The electronic components of the inferior brand chargers are basically made of inferior materials, which are easy to be damaged. The common problem is that the battery does not turn on the lamp after being fully charged, and cannot adjust the charging current according to the current of the battery. The battery will be damaged and scrapped after many times of overcharging.

7. Recharge below 10%

After each use, if possible, charge it. Try not to use the under-voltage to recharge again. Fill up every time. If the battery is kept in a shallow cycle state, its life will be prolonged. At the same time, pay attention to the regular deep discharge, which is beneficial to “activate” the battery and improve the capacity of the battery to a certain extent.

In fact, most of the time, the battery of an electric bicycle is not broken by itself, but due to the nonstandard charging method. Therefore, learn to avoid the wrong charging method, your electric vehicle battery will be able to greatly extend the battery life.
