When the battery is used in series, if the internal resistance of the battery is inconsistent, the battery terminal voltage will be inconsistent in the process of charging and discharging, which will eventually lead to the under charging and premature failure of the whole battery. Therefore, on the electric bicycle, the balance and consistency of the battery pack has a considerable impact on the service life of the battery. For consumers, how to use reasonably will also have a certain impact on the balance and consistency of the battery, thus affecting the service life of the battery. According to the research and practical use of batteries for many years, it is recommended that consumers use batteries reasonably in the following ways.
(1) Riding speed of electric vehicle: 20-25km / h.
(2) Riding distance: 10-30km / day, discharge depth less than or equal to 70% (deep discharge every 2 months).
(3) Charging frequency: once a day.
(4) Load capacity: riding alone (one child under 10 years old can be carried).
According to the above method, the electric bicycle with good quality can be used normally for 3-4 years or even 5 years, and the battery can be used for about 1.5 years. The shallower the discharge depth of the battery, the longer the cycle life of the battery and the longer the service life of the battery. Therefore, consumers generally believe that charging once is a cycle is wrong. In order to prolong the service life of the battery they use, they must always keep the battery in a fully charged state. Under the power loss state for a long time, the negative plate of the battery is very easy to salinize, resulting in the loss of battery capacity and affecting the service life of the battery.
