The market share and prospect of Tricycle Motorcycle in the future

In recent years, the annual actual output has exceeded the social holdings. This is an astonishing data. The lead-acid batteries used in automobiles are only discharged in one direction when they are ignited. After ignition, the generator will automatically charge the battery without causing deep discharge. discharge. However, it is impossible to charge a Tricycle Motorcycle when riding, and it often exceeds 60% of the deep discharge. During deep discharge, the concentration of lead sulfate increases, and the vulcanization will be quite serious.

The 20-kilometer cruising current of a high-current discharge electric vehicle is generally 4A, which is already higher than the operating current of batteries in other fields, and the operating current of an electric vehicle that is overspeeded and overloaded is even greater. Battery manufacturers have conducted cycle life tests of charging 70% at 1C and discharging 60% at 2C. After such a life test, there are many batteries that can achieve a lifespan of 350 charge and discharge cycles, but the actual effect is far from the same. This is because high current work increases the discharge depth by 50%, and the battery will accelerate vulcanization. Therefore, the battery life of the Electric Tricycle Motorcycle is shorter, because the body of the Tricycle Motorcycle is too heavy, and the working current is more than 6A.
Batteries with high frequency of charging and discharging are used in the field of backup power supply. They will only be discharged when the power is cut off. If the power is cut off 8 times a year, to achieve a life span of 10 years, it only needs to achieve 80 cycles of charging life, while an electric car can last for one year. More than 300 charge and discharge cycles are common.
Short-term charging Since the Tricycle Motorcycle is a means of transportation, there is not much charging time. To complete the 36-volt or 48-volt 20-ampere charging within 8 hours, it is necessary to increase the charging voltage. When the charging voltage exceeds a single battery When the oxygen evolution voltage or hydrogen evolution voltage is low, the battery will open the valve to exhaust due to excessive oxygen evolution, resulting in water loss, increasing the concentration of the electrolyte, and aggravating the vulcanization of the battery. Cannot be charged in time after discharge As a means of transportation, the charging and discharging of the Tricycle Motorcycle are completely separated, it is difficult to charge in time after discharging, and a large amount of lead sulfate formed after discharging will be reduced to lead oxide if it is not charged for more than half an hour , will sulfide and form crystals.
