Lithium ion battery pack capable of delaying output

The invention discloses a lithium ion battery pack capable of delaying output. The lithium ion battery pack comprises a battery stack; the charging socket is electrically connected with the input end of the battery stack; the input end of the protection plate is electrically connected with the output end of the cell stack; the time delay relay is electrically connected with the output end of the protection plate; and the output control socket is electrically connected with the output end of the time delay relay. The output current of the battery stack and the time needing to be delayed are controlled through the time-delay relay, a voltage signal is provided for the coil end of the time-delay relay, time-delay on-off of a switch loop of the time-delay relay is controlled, the effect of delay output of the battery stack is achieved, and the problem that the voltage signal cannot be firstly sent to the battery pack and the time cannot be delayed is solved. And after the control signal is interrupted, the output
