Embodiment 1

[0008] A charging method for the pre-charging stage of an electric vehicle battery charger, in which a battery with a voltage of 48v and a capacity of 100AH ​​is charged and charged with a current of 10A for three minutes, stopped for ten seconds, then charged again for three minutes and stopped for ten seconds, so as to repeat until The whole pre-charging stage is completed until the battery voltage reaches 48v.

Embodiment 2

[0010] A charging method for the pre-charging stage of an electric vehicle battery charger, in which a battery with a voltage of 48v and a capacity of 130AH is charged and charged with a current of 13A for three minutes, stopped for ten seconds, then charged again for three minutes and stopped for ten seconds, so as to repeat until The whole pre-charging stage is completed until the battery voltage reaches 48v.

Embodiment 3

[0012] A charging method for the pre-charging stage of an electric vehicle battery charger, in which a battery with a voltage of 60v and a capacity of 130AH is charged and charged with a current of 13A for three minutes, stopped for ten seconds, then charged again for three minutes and stopped for ten seconds, so as to repeat until The whole pre-charging stage is completed until the battery voltage reaches 60v.

Abstract

The present invention relates to an electric vehicle storage battery charger charging method, particularly to a pre-charging stage charging method. The method comprises: according to the battery capacity, selecting different currents to charge for 3 min and stopping for 10 s, charging for 3 min and stopping for 10 s, and repeatedly performing the steps until the storage battery voltage achieves the volt value of the storage battery so as to complete the pre-charging stage, wherein the battery capacity divided by 10 is the current value. The electric vehicle storage battery charger pre-charging stage charging method has advantages of storage battery service life prolonging and storage battery charge-discharge number increasing.

Description

technical field [0001] The invention relates to a charging method of a battery charger for an electric vehicle, in particular to a charging method in a pre-charging stage. technical background [0002] When the electric vehicle battery is in the state of power loss, it is not suitable for charging with a large current. During the charging process, it needs to be pre-charged with a small current, and then converted to a suitable high current for charging. Many batteries on the market have The function of the pre-charging stage, but can not achieve satisfactory results. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to provide a charging method for battery chargers for electric vehicles, which can protect the battery, prolong the service life of the battery, and increase the number of charge and discharge times of the battery. [0004] In order to solve the above-mentioned technical problems, the present in...
