Title: Charging system, charging method, and program
Inventor: IKEDA MASAKI
IPC: H01M10/48
Filed: 2020-03-31
Abstract: To improve reliability in charging a battery pack.SOLUTION: A charging system 100 charges a battery pack 5 having one or a plurality of battery cells 50. The charging system 100 comprises an acquisition unit 11 and a control unit 12. The acquisition unit 11 acquires, as an acquisition voltage, an inter-terminal voltage V1 or cell voltage of each battery cell 50 of the battery pack 5 during charging. When the inter-terminal voltage V1 or cell voltage reaches a target voltage, the control unit 12 performs a shift from a first charging form for enabling quick charging to a second charging form using charging current lower than that in the first charging form. When the acquisition voltage acquired by the acquisition unit 11 reduces and a situation of the reduction in the acquisition voltage satisfies a predetermined condition in the second charging form, the control unit 12 stops charging operation.SELECTED DRAWING: Figure 1
