Reasonable use of electric vehicle batteries

When using batteries in series, if the internal resistance of the batteries is inconsistent, the voltage at the battery terminals during the charging and discharging process will be inconsistent, which will ultimately cause the entire set of batteries to be under charged and fail prematurely. Therefore, in electric bicycles, the balance and consistency of the battery pack have a significant impact on the service life of the battery. For consumers, how to use it reasonably can also have a certain impact on the balance and consistency of the battery, thereby affecting its service life. Based on years of research and practical use of batteries, it is recommended that consumers use batteries in a reasonable manner using the following methods.

(1) Electric bike riding speed: 20-25km/h.

(2) Cycling distance: 10-30km/day, with a discharge depth of 70% or less (deep discharge every 2 months).

(3) Charging frequency: once a day.

(4) Load capacity: Single person cycling (can carry one child under 10 years old).

According to the above method, high-quality electric bicycles can be used normally for 3-4 years, or even 5 years, and the battery can be used for about 1 and a half years. The shallower the discharge depth of the battery, the longer its cycle life and service life. Therefore, the common belief among consumers that charging once is a cycle is incorrect. In order to extend the lifespan of the battery they are using, it is necessary to keep the battery fully charged at all times. In a state of long-term battery depletion, the negative electrode plate of the battery is prone to salinization, causing a loss of battery capacity and affecting its service life.
