China Electric Bike Manufacturer introduced the reasons for battery power consumption:

1. Deep discharge
The lead-acid battery used in the car only discharges unidirectionally during ignition, and the generator will automatically charge the battery after ignition, without causing deep battery discharge. However, it is impossible to charge
an electric bicycle while riding, and it will often exceed 60% of the deep discharge. During deep discharge, the concentration of lead sulfate increases, and the vulcanization will be quite serious.

2. High current discharge
The 20-kilometer cruising current of an electric vehicle is generally 4A, which is already higher than the operating current of batteries in other fields, while the operating current of an electric vehicle that is overspeeding and
overloading is even greater. Battery manufacturers have conducted cycle life tests of 70% charging at 1C and 60% discharging at 2C. After such a life test, there are many batteries with a life span of 350 charge and discharge cycles, but the actual effect is far different. This is because the high current operation increases the depth of discharge by 50%, and the battery will accelerate the vulcanization. Therefore, the battery life of an electric three-wheeled motorcycle is shorter, because the body of the three-wheeled motorcycle is too heavy, and the working current is more than 6A.

3. High charging and discharging frequency
The battery used in the field of backup power supply will only be discharged when the power is cut off. If the power is stopped 8 times a year, it will reach a life of 10 years, and only need to achieve a charging life of 80 cycles,
while the charging and discharging cycle of an electric vehicle is 300 per year. More than one time is very common.

4. Short-time charging
Since electric bicycles are vehicles, there is not much time to charge them. To complete the charging of 36 volts or 48 volts at 20-ampere hours within 8 hours, it is necessary to increase the charging voltage (usually 2.7 to 2.9 volts
per cell). When the voltage exceeds the oxygen evolution voltage (2.35 volts) or hydrogen evolution voltage (2.42 volts) of a single cell battery, the battery will open the valve and exhaust due to excessive oxygen evolution, causing loss of water, increasing the electrolyte concentration, and increasing the vulcanization of the battery.

5. Can not be charged in time after discharge
As a means of transportation, the charging and discharging of electric bicycles are completely separated. It is difficult to charge in time after discharge. If a large amount of lead sulfate formed after discharging is not charged and
reduced to lead oxide for more than half an hour, it will be vulcanized and formed into crystals.
