① The best approach for large-capacity lithium-ion battery packs in electric vehicles is to charge them regularly. This allows the battery to be in an infinite cycle state, extending its lifespan.
② For long-distance flights, charge the battery promptly after use. Lithium-ion batteries begin sulfation after discharge; timely charging removes minor sulfation and doesn't shorten battery life. Therefore, in addition to regular charging, charge the battery as soon as possible after use to keep it at a full charge level. Besides charging, also perform deep discharges periodically to help activate the battery.
③ Do not use lithium-ion battery packs in low-temperature environments. When the temperature is below 0℃, do not charge them outdoors, as they will not charge. You can bring the battery indoors to charge it. When the temperature is below -20℃, the battery will automatically enter a dormant state and cannot be used normally.
④ Develop the habit of charging whenever needed. In winter, when the lithium-ion battery pack has low power, we should charge it in time and develop the good habit of charging whenever needed. Remember, never estimate the battery power in winter based on the normal battery life.
⑤ The charging time for lithium-ion batteries in electric vehicles is generally around 1.5 to 3 hours. Do not leave the vehicle in a charging state for extended periods for convenience; simply unplug it once fully charged. In winter, the charging environment should not be below 0°C. Do not leave the charging area too far away while charging to prevent any unexpected situations and ensure prompt handling.
⑥ Pay attention to the lifespan of lithium-ion batteries and replace them in time. Lithium-ion battery packs have a lifespan, and the lifespan of different specifications and models of batteries is different. In addition, improper daily use can cause the battery lifespan to vary from a few months to three years. If the battery cannot be charged or discharged, please contact the official supplier in time to replace it.
⑦ Leave some residual power. To ensure normal vehicle use next spring, if the lithium-ion battery will not be used for a long period, remember to charge it to 50%~80% and remove it from the vehicle for storage. Charge it regularly, about once a month. Note: The battery must be stored in a dry environment.
