Our electric vehicle battery charging inappropriate greatly reduces battery life 1, the charging and discharging high frequency fields used in backup power supply battery will discharge only during a power outage, if eight times a year to stop electricity, to reach 10 years of life, only to do 80 cycles charge life, while electric cars a year more than 300 times charge-discharge cycles are common. 2, due to the short charging electric bike is a vehicle, not much can be charging time to complete charging 36 volt or 48 volt 20 amp within eight hours, which must improve the charging voltage (typically a single 2.7 to 2.9 V), when more than a single battery charge voltage oxygen evolution voltage (2.35 V) or hydrogen evolution voltage (2.42 V), the battery will be due to excessive oxygen evolution and open the exhaust valve, stroller battery, resulting in dehydration, electrolyte solution concentration, curing phenomenon aggravated battery. 3, can not be charged after discharge electric cars as transportation tools, electric bicycles charging and discharging are completely separated, difficult conditions after discharge timely charge, quality stroller batteries battery, and a lot of lead sulfate formed after discharge if more than half hours without charge reduced to lead oxide, sulfide will form crystals.
