Problems solved by technology

After the grid is cast, it needs to be hardened. The hardening time is generally 72-168 hours. During this time, a dense oxide film will be formed on the surface of the grid. The thickness of the oxide film dissolves, and the thickness of the oxide film will cause the battery to respond inconsistently during charging; it is also difficult to achieve an absolute consistency in the weight of the paste when coating the board. The reaction with a small amount of paste is fast, and the response with a large amount of paste is slow. This is also the factor that causes the inconsistency of the battery formation reaction.

Abstract

The invention discloses a method for the internalization of storage batteries of an electric bicycle, which is used for solving the problem of cycle life loss caused by inconsistent voltage of all storage batteries. The method comprises a plurality of charging and discharging stages and is characterized in that: in the last stage for charging and discharging, several storage batteries constituting a storage battery pack of the electric bicycle are connected in parallel to form a group and are changed for 0.5-1 hour by adopting the constant voltage of 14.8V and the limited current of 2-4A. According to the invention, reverse charging is performed in the first stage of the internalization to solve the problems of larger initial electric internal resistance and heat generation; and in the last stage, several storage batteries of the storage battery pack of the electric bicycle are connected in parallel to form a group and are charged by adopting the constant voltage of 14.8V and the limited current of 2-4A, so that the problem of life loss of the storage batteries due to inconsistency is solved completely. By means of the method disclosed by the invention, the consistency of the internalization of the storage batteries of the electric bicycle can be increased, so that the service life of the storage batteries can be prolonged.
