Abstract:
The present invention provides a charging control method and apparatus, a charging test method and system, and an electronic device. The charging control method comprises: obtaining the charging state of a cell core and charging the cell core at a charging current corresponding to the charging state according to a pre-stored correspondence between the charging state and the charging current, wherein the pre-stored correspondence between the charging state and the charging current is obtained by: adjusting a test charging current of the cell core according to the monitored lithium precipitation state of a negative electrode of the cell core, recording the corresponding test charging state, and using the correspondence between the generated test charging state and the test charging current as the pre-stored correspondence between the charging state and the charging current. The present invention ensures the charging safety of the cell core while quickly charging the cell core.
