Will charging an ebike when it runs out of power affect the health of the battery?

The battery is the part that provides power for electric bicycles. The charging method affects the life of the battery. Some riders choose to charge the battery after it is used up, while some riders charge the battery immediately after the ride. So which of these two charging methods will have less impact on the battery? This article tells you the answer.

Risk analysis of charging an ebike after it runs out of power and charging it right after riding

The impact of recharging after the battery is empty

• Recharging after the battery is out of power will cause deep discharge of the battery, damage the internal plates of the battery, increase the internal resistance of the battery, and inactivate the substances that generate ions inside, thus causing the internal capacity to decrease.
• This is why newly bought batteries can always travel longer distances.

The impact of charging after riding on the battery

• After a long ride, the temperature of an electric bicycle using lithium batteries is already at a relatively high level.
• Charging immediately after riding may cause the battery temperature to continue to rise, which may lead to the risk of fire or even explosion.

Comparison of the risks of charging an ebike after it runs out of power and charging it right after riding

For electric bicycles using lithium batteries, charging them after riding will damage the batteries more.

• The reason is that lithium batteries have no battery memory. Frequent non-deep discharge will affect lithium ions, causing lithium ions to become inactive, reducing battery capacity and life. Correct operation should be to charge the battery when there is 30% power left, reducing the frequency of charging.

How to Charge Properly to Extend Battery Life

1. When charging, plug the electric bicycle into the power port first, then plug it into the 220V power port to avoid the instantaneous high voltage generated when the electric bicycle is plugged into the charger; when fully charged, unplug the bicycle charging port first, then unplug the 220V power supply, which can avoid the battery being reversely charged through the charger when the power is off, thus protecting the battery.
2. Use a charger with a power-off protection function. If you use a charger without a power-off protection function, the battery may be overheated due to a long charging time, which may cause thermal runaway and lead to a fire.
3. Avoid overcharge and over discharge, overcharging and over-discharging will cause excessive gas to be generated inside the battery and the active substances to be deactivated, resulting in a decrease in battery capacity, an increase in internal resistance, and a decrease in battery discharge performance.
4. Avoid parking or charging in high-temperature outdoor environments. When using an electric bicycle, in order to protect the battery, avoid exposing the battery to high temperatures. High temperatures will increase the temperature inside the battery, increase the battery's self-discharge rate, and shorten the battery life.
5. Electric bicycles must master the correct charging timing and charging time. Generally, the battery should be charged when there is 30% power left. When the charger indicator light turns from red to green, the power should be cut off in time. In winter, you can wait for half an hour after the red light turns green before cutting off the power. If you need to leave it idle for a long time, you can charge it once every half a month.
6. It is very important to regularly check the appearance and performance of the battery, so that you can find battery problems in time and take appropriate measures to avoid situations that may cause battery safety hazards.

Make a conclusion

In fact, charging after the battery is out of power or charging after riding will damage the battery. The normal charging method is very important to extend the life of the battery. Developing good charging habits and paying attention to the changes in the battery are the key to extending the battery life.
