The invention discloses a lithium battery online charging device, which adopts each rectification power supply in a series rectification power supply pack to charge each lithium battery in a series lithium battery pack, thereby ensuring that each lithium battery can realize independent charging management, ensuring that each lithium battery can be fully charged, and realizing balance of the electric quantity of each lithium battery. Meanwhile, the positive electrodes of the series lithium battery pack and the rectification power supply pack are connected with a positive output end, and the negative electrodes of the series lithium battery pack and the rectification power supply pack are connected with a negative output end; and the series connection relation of all lithium batteries in thelithium battery pack does not need to be disconnected during charging, so that it is ensured that the lithium battery pack is kept in a standby state during charging, and the high requirement for online standby power in the
