The ideal charging time for Electric bicycle is based on the normal charging duration. When the remaining battery level of an Electric bicycle is around 20%, it is recommended to start charging. The typical charging time is approximately 8-10 hours, with a maximum limit of 12 hours. Once the charging indicator on the charger changes from red to green, a float charge of 1-2 hours can be conducted before unplugging the charger, ensuring that the residual charge in the battery is also replenished.
Unlike lead-acid batteries, lithium-ion batteries in Electric bicycle can be charged using shallow charging methods. This approach prevents the battery from completely draining and helps extend its lifespan. Lithium-ion batteries do not have memory effects, so regular charging is sufficient. However, it is not advisable to charge the battery when it is completely empty, as this may cause certain damage to the battery.
The recommended charging duration for lithium-ion batteries is explicitly stated in the product manual. To ensure the battery’s longevity, it is best to use the charger provided by the original manufacturer for charging. This helps guarantee the battery’s proper functioning. During lithium-ion battery charging, it is important to avoid high-temperature environments, and the temperature should be kept within the range of -20°C to 60°C. In winter, the charging time can be slightly extended to ensure a full charge.
Newer lithium-ion batteries have larger capacities and longer charging times.
However, after a few months, the charging duration may shorten. For example, it could reduce from 10 hours to 6 hours and eventually settle around 3-5 hours. Generally, when the lithium-ion battery is fully charged, the indicator light changes from red to green. It is acceptable to extend the charging time by 1-2 hours when the indicator light is on.
However, excessively long charging times can cause excessive lithium ion deintercalation from the positive electrode, thereby reducing the battery’s capacity and shortening its lifespan.
Similar to lead-acid batteries, it is not advisable to wait until the lithium-ion battery is completely drained before charging. This practice can adversely affect battery performance and lifespan. If an Electric bicycle is left unused for a long period, it should be regularly charged to prevent battery depletion.
Additionally, if battery deformities or significant energy storage deficiencies are detected, it is essential to promptly replace the battery to ensure a satisfactory user experience and personal safety.
