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, causing water loss, so that the electrolyte concentration, vulcanization phenomenon aggravated battery. 3, can not be charged after discharge electric cars as a vehicle battery life of electric vehicles, electric bicycles charging and discharging are completely separated, difficult conditions after discharge timely charge, while a large number of lead sulfate formed after discharge if more than half an hour No charge is reduced to lead oxide, sulfide will form crystals.

Now, electric vehicle batteries charts, each car is a 12V battery, each battery capacity is large, the smallest car battery capacity also 32Ah. Capacity then small, although you can use the car, but winter is not easy launch electric cars, there are two, one is electric bicycles (including electric motorcycles, electric bikes, electric wheelchairs, electric Handicapped vehicles, electric tricycle, electric freight cars, electric police cars, etc.), and the other is electric car electric cars was divided fully charged and hybrid electric vehicles. Electric bicycles, a 12V battery electric vehicle batteries, 20V also, of course, there are 36V, 48V, 60V electric car battery brand, or even 72V Of course, the voltage of the electric car batteries get nothing but a combination of different battery cells. And electric bicycle battery capacity to the car, to small lot. Most of the battery capacity is 20Ah, the capacity is also 10Ah, 12Ah, 14Ah, 30Ah, 36Ah, 42Ah, 50Ah, 58Ah, 60Ah, 76Ah, such as different kinds of specifications. General Electric Bicycle mostly use 20Ah, but some electric goods moving vehicles and other large EMU choose larger capacity battery. now electric bicycle battery capacity is no national standard for unified regulations. bike rider in order to reduce the hassle and safety, mostly maintenance-free batteries (dry) batteries.
