Insufficient electric power continuation mileage after one-time battery charge

“Continuation mileage”means that after the new battery, means that after the new battery is fully charged, its weight is configured to 75kg(The rider’s weight), the ambient temperature is 25℃±5℃, and the wind speed is not more than 3m/s. Ride on a flat secondary road until it reaches the mileage under the condition of battery undervoltage.

a) With the passage of time, the capacity of the battery has decreased. For example, the new battery may have a “continuation mileage” of more than 30 kilometers. After a period of use, the battery capacity will decrease as the use time increases, so the “continuation mileage” will decrease.

b) Riding under poor road conditions, headwinds, uphills, loads, frequent starts, insufficient tire pressure, etc., will make the riding current increase and the battery discharge time reduce, so the “continuation mileage” will be somewhat decreased.

c) As the temperature drops, the capacity of the battery will decrease. When the actual “continuation mileage” is at 25°C±5°C standard temperature, every 1°C drop will shorten the “continuation mileage” by approximately 0.5-0.6km.

d) Improper charging of the battery will reduce the capacity of the battery, thereby affecting the “continuing mileage”.

-1 Riding in low temperature conditions. Once you get home, You’ll’t charge it at low temperature immediately. If you do, the battery will be falsely charged and the capacity will gradually decrease. Because at low temperatures, the chemical reaction on the battery electrodes is very slow, the charge acceptance is very poor, and it is difficult to fully charge. Therefore, you should put the battery to a room above 15°C, and then recharge the battery after 1 hour.

-2 Considering the riding distance and needs, frequent charging is beneficial to the battery life. Then again, when the battery is fully discharged and then recharged, because of the difference between the single cells all over discharge, some single cells may be over-discharged. Over-discharge will greatly reduce the charge acceptance ability, cause insufficient charge, and gradually decrease the capacity. Therefore, when the battery discharges 50-70% of the power, it’s the right time to charge the battery.
